Moderate drug interactions

Moderate:

acetaminophen ozanimod

Applies to: Cough & Cold Relief (acetaminophen / dextromethorphan / guaifenesin / phenylephrine) and ozanimod
Monitor

Coadministration of acetaminophen with other potentially hepatotoxic agents may increase the risk of liver injury. The mechanism may involve additive hepatotoxic effects and, for some medicines, increased formation of hepatotoxic acetaminophen metabolites due to induction of hepatic enzymes. Therapeutic-dose acetaminophen-induced hepatotoxicity, including fatal cases, has been reported in patients with factors associated with increased hepatotoxicity risk, including concomitant use of hepatotoxic drugs, low body weight, renal or hepatic impairment, chronic alcoholism, and malnutrition or other conditions associated with glutathione depletion.

Management

Caution is advised when acetaminophen is used with other potentially hepatotoxic agents, particularly in patients with additional risk factors for hepatotoxicity. Alternative therapy may be considered when appropriate. Patients should not exceed the recommended acetaminophen dosage or use multiple acetaminophen-containing products concurrently. Patients should be monitored for clinical signs and symptoms of liver injury, and liver function monitoring may be appropriate in patients receiving prolonged or high-dose therapy or those at increased risk of hepatotoxicity. If liver injury is suspected, paracetamol should be discontinued and the patient evaluated promptly.

Moderate:

dextromethorphan ozanimod

Applies to: Cough & Cold Relief (acetaminophen / dextromethorphan / guaifenesin / phenylephrine) and ozanimod
Generally avoid

Coadministration of serotonergic agents (e.g., selective serotonin reuptake inhibitors (SSRIs), 5-HT1 receptor agonists (triptans), ergot alkaloids, buspirone, dextromethorphan, St. John's wort) with drugs that possess monoamine oxidase inhibition (MAOI) activity may potentiate the risk of serotonin syndrome, which is a rare but serious and potentially fatal condition thought to result from hyperstimulation of brainstem 5-HT1A and 2A receptors. Symptoms of the serotonin syndrome may include mental status changes such as irritability, altered consciousness, confusion, hallucinations, and coma; autonomic dysfunction such as tachycardia, hyperthermia, diaphoresis, shivering, blood pressure lability, and mydriasis; neuromuscular abnormalities such as hyperreflexia, myoclonus, tremor, rigidity, and ataxia; and gastrointestinal symptoms such as abdominal cramping, nausea, vomiting, and diarrhea. Because an active metabolite of ozanimod inhibits MAO-B in vitro, the interaction may theoretically occur with ozanimod. In clinical trials, a small number of patients treated with ozanimod were concomitantly exposed to serotonergic medications; however, this exposure was not adequate to rule out the possibility of an adverse reaction from coadministration.

Management

Until more information is available, concomitant use of ozanimod with serotonergic agents should be avoided when possible. Blood pressure and other vitals should be monitored if coadministration is required.

Moderate:

phenylephrine ozanimod

Applies to: Cough & Cold Relief (acetaminophen / dextromethorphan / guaifenesin / phenylephrine) and ozanimod
Generally avoid

Coadministration of sympathomimetic agents with drugs that possess monoamine oxidase inhibition (MAOI) activity may precipitate severe hypertensive reactions and hyperpyrexia. Death has occurred in some reported cases. The mechanism involves a synergistic sympathomimetic effect due to enhanced norepinephrine storage in adrenergic neurons secondary to MAOI activity. MAOIs also slow the metabolism of some sympathomimetics such as amphetamines, which may potentiate their effect on the release of norepinephrine and other monoamines from adrenergic nerve endings. Although the interaction has primarily involved nonselective MAOIs, hypertensive crisis has been reported with selective MAO-B inhibitors. Because an active metabolite of ozanimod inhibits MAO-B in vitro, the interaction may theoretically occur with ozanimod. In a placebo-controlled crossover study involving healthy subjects, coadministration of ozanimod with pseudoephedrine did not potentiate the effects on blood pressure; however, ozanimod did increase the pseudoephedrine-induced heart rate response by approximately 3 beats per minute (bpm). In two clinical studies, ozanimod increased systolic pressure by an average of 1 to 2 mmHg over interferon beta-1a, but had no effect on diastolic pressure. The increase in systolic pressure was first detected after approximately 3 months of treatment and persisted throughout treatment. Hypertension was reported as an adverse reaction in 3.9% of patients treated with ozanimod 0.92 mg, compared to 2.1% of patients treated with interferon beta-1a. Two patients treated with ozanimod and one patient treated with interferon beta-1a in these studies experienced a hypertensive crisis.

Management

Until more information is available, concomitant use of ozanimod with sympathomimetic agents should be avoided when possible. Blood pressure and other vitals should be monitored if coadministration is required.

Food/lifestyle interactions

Major food/lifestyle interactions

Major:

acetaminophen Food/Lifestyle

Applies to: Cough & Cold Relief (acetaminophen / dextromethorphan / guaifenesin / phenylephrine)
Generally avoid

Chronic, excessive consumption of alcohol may increase the risk of acetaminophen-induced hepatotoxicity, which has included rare cases of fatal hepatitis and frank hepatic failure requiring liver transplantation. The proposed mechanism is induction of hepatic microsomal enzymes during chronic alcohol use, which may result in accelerated metabolism of acetaminophen and increased production of potentially hepatotoxic metabolites.

Management

In general, chronic alcoholics should avoid regular or excessive use of acetaminophen. Alternative analgesic/antipyretic therapy may be appropriate in patients who consume three or more alcoholic drinks per day.

Moderate food/lifestyle interactions

Moderate:

dextromethorphan Food/Lifestyle

Applies to: Cough & Cold Relief (acetaminophen / dextromethorphan / guaifenesin / phenylephrine)
Generally avoid

Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

Management

Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

ozanimod Food/Lifestyle

Applies to: ozanimod
Generally avoid

Foods that contain large amounts of tyramine may precipitate a hypertensive crisis in patients treated with ozanimod. The proposed mechanism involves potentiation of the tyramine pressor effect due to inhibition of monoamine oxidase (MAO) by the major active metabolites of ozanimod, CC112273 and CC1084037. Monoamine oxidase in the gastrointestinal tract and liver, primarily type A (MAO-A), is the enzyme responsible for metabolizing exogenous amines such as tyramine and preventing them from being absorbed intact. Once absorbed, tyramine is metabolized to octopamine, a substance that is believed to displace norepinephrine from storage granules causing a rise in blood pressure. In vitro, CC112273 and CC1084037 inhibited MAO-B (IC50 values of 5.72 nM and 58 nM, respectively) with more than 1000-fold selectivity over MAO-A (IC50 values >10000 nM). Because of this selectivity, as well as the fact that free plasma concentrations of CC112273 and CC1084037 are less than 8% of the in vitro IC50 values for MAO-B inhibition, ozanimod is expected to have a much lower propensity to cause hypertensive crises than nonselective MAO inhibitors. However, rare cases of hypertensive crisis have occurred during clinical trials for the treatment of multiple sclerosis (MS) and ulcerative colitis (UC) and in postmarketing use. In controlled clinical trials, hypertension and blood pressure increases were reported more frequently in patients treated with ozanimod (up to 4.6% in MS patients receiving ozanimod 0.92 mg/day) than in patients treated with interferon beta-1a (MS) or placebo (UC). Administration of ozanimod with either a high-fat, high-calorie meal (1000 calories; 50% fat) or a low-fat, low-calorie meal (300 calories; 10% fat) had no effects on ozanimod peak plasma concentration (Cmax) and systemic exposure (AUC) compared to administration under fasted conditions.

Management

Dietary restriction is not ordinarily required during ozanimod treatment with respect to most foods and beverages that contain tyramine, which usually include aged, fermented, cured, smoked, or pickled foods (e.g., air-dried and fermented meats or fish, aged cheeses, most soybean products, yeast extracts, red wine, beer, sauerkraut). However, certain foods like some of the aged cheeses (e.g., Boursault, Liederkrantz, Mycella, Stilton) and pickled herring may contain very high amounts of tyramine and could potentially cause a hypertensive reaction in patients taking ozanimod, even at recommended dosages, due to increased sensitivity to tyramine. Patients should be advised to avoid the intake of very high levels of tyramine (e.g., greater than 150 mg) and to promptly seek medical attention if they experience potential signs and symptoms of a hypertensive crisis such as severe headache, visual disturbances, confusion, stupor, seizures, chest pain, unexplained nausea or vomiting, and stroke-like symptoms. Blood pressure should be regularly monitored and managed accordingly. Because of the long elimination half-lives of the major active metabolites, these precautions may need to be observed for up to 3 months following the last ozanimod dose. Ozanimod can be administered with or without food.

Moderate:

phenylephrine Caffeine

Applies to: Cough & Cold Relief (acetaminophen / dextromethorphan / guaifenesin / phenylephrine)
Monitor

Coadministration of two or more sympathomimetic or noradrenergic agents may increase the risk of nervousness, irritability, tachycardia, and/or increased blood pressure. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic and/or noradrenergic agents, including norepinephrine transporter inhibitors. Additive increases in blood pressure and heart rate may occur due to enhanced peripheral sympathetic activity.

Management

Caution is advised if two or more sympathomimetic or noradrenergic agents are coadministered. Pulse and blood pressure should be closely monitored. Consultation with individual product labeling, as well as relevant institutional protocols, may be advisable for further guidance.

Disease interactions

28 potential interactions Applies to: 24 conditions, including High Blood Pressure, Benign Prostatic Hyperplasia, Arrhythmia, Sleep Apnea, and Multiple Sclerosis.

Alcoholism

Major:

Cough & Cold Relief

The acetaminophen in Cough & Cold Relief has a major potential interaction with Alcoholism.

Chronic alcohol abusers may be at increased risk of hepatotoxicity during treatment with acetaminophen (APAP). Severe liver injury, including cases of acute liver failure resulting in liver transplant and death, has been reported in patients using acetaminophen. Therapy with acetaminophen should be administered cautiously, if at all, in patients who consume three or more alcoholic drinks a day. In general, patients should avoid drinking alcohol while taking acetaminophen-containing medications. Patients should be warned not to exceed the maximum recommended total daily dosage of acetaminophen (4 g/day in adults and children 12 years of age or older), and to read all prescription and over-the-counter medication labels to ensure they are not taking multiple acetaminophen-containing products, or check with a healthcare professional if they are unsure. They should also be advised to seek medical attention if they experience signs and symptoms of liver injury such as fever, rash, anorexia, nausea, vomiting, fatigue, right upper quadrant pain, dark urine, and jaundice.

Arrhythmia

Moderate:

ozanimod

Ozanimod has a moderate potential interaction with Arrhythmia.

The use of ozanimod may result in a transient decrease in heart rate and atrioventricular conduction delays upon starting treatment. It is recommended to follow an up-titration scheme to reach the maintenance dosage. Initiation of ozanimod without titration may result in greater decreases in heart rate. If treatment with ozanimod is considered, advice from a cardiologist should be sought for those individuals at risk of cardiovascular effects, particularly conduction delays.

Benign Prostatic Hyperplasia

Moderate:

Cough & Cold Relief

The phenylephrine in Cough & Cold Relief has a moderate potential interaction with Benign Prostatic Hyperplasia.

Sympathomimetic agents may cause or worsen urinary difficulty in patients with prostate enlargement due to smooth muscle contraction in the bladder neck via stimulation of alpha-1 adrenergic receptors. Therapy with sympathomimetic agents should be administered cautiously in patients with hypertrophy or neoplasm of the prostate.

Cardiovascular Conditions and Disorders

Major:

Cough & Cold Relief

The phenylephrine in Cough & Cold Relief has a major potential interaction with Cardiovascular Conditions and Disorders.

Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.

Major:

ozanimod

Ozanimod has a major potential interaction with Cardiovascular Conditions and Disorders.

Ozanimod is contraindicated in patients who have had a recent myocardial infarction, those with unstable angina, stroke, transient ischemic attack, decompensated heart failure with hospitalization, or Class III/IV heart failure, a presence of Mobitz Type II 2nd degree or 3rd degree AV block, sick sinus syndrome, or sino-atrial block, unless the patient has a pacemaker, severe untreated sleep apnea or those patients being treated with monoamine oxidase inhibitor drugs.

Moderate:

ozanimod

Ozanimod has a moderate potential interaction with Cardiovascular Conditions and Disorders.

The use of ozanimod may result in a transient decrease in heart rate and atrioventricular conduction delays upon starting treatment. It is recommended to follow an up-titration scheme to reach the maintenance dosage. Initiation of ozanimod without titration may result in greater decreases in heart rate. If treatment with ozanimod is considered, advice from a cardiologist should be sought for those individuals at risk of cardiovascular effects, particularly conduction delays.

Central Nervous System Disorders

Moderate:

ozanimod

Ozanimod has a moderate potential interaction with Central Nervous System Disorders.

Rare cases of posterior reversible encephalopathy syndrome (PRES) have been reported in patients receiving a sphingosine 1-phosphate receptor modulator. It is recommended to promptly schedule a complete physical and neurological examination and should consider an MRI, if a patient develops any unexpected neurological or psychiatric symptoms/signs, any symptom/sign suggestive of an increase of intracranial pressure, or accelerated neurological deterioration. Delay in diagnosis and treatment may lead to permanent neurological sequelae. Exercise care when using this agent in patients with a history of ischemic stroke or cerebral hemorrhage. Treatment should be discontinued if PRES is suspected.

Cerebrovascular Insufficiency

Major:

Cough & Cold Relief

The phenylephrine in Cough & Cold Relief has a major potential interaction with Cerebrovascular Insufficiency.

Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.

Dehydration

Major:

Cough & Cold Relief

The acetaminophen in Cough & Cold Relief has a major potential interaction with Dehydration.

Acetaminophen is contraindicated in patients with severe hepatic impairment or severe active liver disease. Patients with hepatic impairment may be at increased risk of toxicity. Severe liver injury, including cases of acute liver failure and death, have been reported in patients using this drug. Clinical monitoring of hepatic function is recommended. Caution is advised if using acetaminophen in patients with chronic malnutrition or severe hypovolemia. Instruct patients to avoid drinking alcohol while taking acetaminophen-containing medications. Patients should be warned not to exceed the maximum recommended total daily dosage of acetaminophen (4 g/day in adults and children 12 years of age or older), and to read all prescription and over-the-counter medication labels to ensure they are not taking multiple acetaminophen-containing products, or check with a healthcare professional if they are unsure.

Diabetes Mellitus

Moderate:

Cough & Cold Relief

The phenylephrine in Cough & Cold Relief has a moderate potential interaction with Diabetes Mellitus.

Sympathomimetic agents may cause increases in blood glucose concentrations. These effects are usually transient and slight but may be significant with dosages higher than those normally recommended. Therapy with sympathomimetic agents should be administered cautiously in patients with diabetes mellitus. Closer monitoring of blood glucose concentrations may be appropriate.

Moderate:

ozanimod

Ozanimod has a moderate potential interaction with Diabetes Mellitus.

Macular edema has been reported with the use of sphingosine 1-phosphate (S1P) receptor modulators. Care should be exercised when using these drugs in patients with a history of uveitis and patients with diabetes mellitus as these patients are at increased risk for macular edema. Before starting treatment with these agents, an ophthalmic evaluation of the fundus, including the macula, is recommended in all patients and at any time if vision change is reported during treatment. Patients with a history of uveitis and patients with diabetes mellitus should have regular follow-up examinations of the fundus, including the macula during treatment. Continuation of therapy in patients with macular edema has not been evaluated, therefore, a decision on whether or not to discontinue treatment needs to take into account the potential benefits and risks for the individual patients.

Glaucoma/Intraocular Hypertension

Moderate:

Cough & Cold Relief

The phenylephrine in Cough & Cold Relief has a moderate potential interaction with Glaucoma/Intraocular Hypertension.

Sympathomimetic agents can induce transient mydriasis via stimulation of alpha-1 adrenergic receptors. In patients with anatomically narrow angles or narrow-angle glaucoma, pupillary dilation can provoke an acute attack. In patients with other forms of glaucoma, mydriasis may occasionally increase intraocular pressure. Therapy with sympathomimetic agents should be administered cautiously in patients with or predisposed to glaucoma, particularly narrow-angle glaucoma.

Heart Disease

Major:

ozanimod

Ozanimod has a major potential interaction with Heart Disease.

Ozanimod is contraindicated in patients who have had a recent myocardial infarction, those with unstable angina, stroke, transient ischemic attack, decompensated heart failure with hospitalization, or Class III/IV heart failure, a presence of Mobitz Type II 2nd degree or 3rd degree AV block, sick sinus syndrome, or sino-atrial block, unless the patient has a pacemaker, severe untreated sleep apnea or those patients being treated with monoamine oxidase inhibitor drugs.

High Blood Pressure

Moderate:

ozanimod

Ozanimod has a moderate potential interaction with High Blood Pressure.

The use of ozanimod may result in increased blood pressure. Care should be exercised when using this drug in hypertensive patients and those at risk for hypertension. It is recommended to monitor blood pressure during treatment and manage it according to clinical practices.

Hyperthyroidism

Major:

Cough & Cold Relief

The phenylephrine in Cough & Cold Relief has a major potential interaction with Hyperthyroidism.

Sympathomimetic agents may cause adverse cardiovascular effects, particularly when used in high dosages and/or in susceptible patients. In cardiac tissues, these agents may produce positive chronotropic and inotropic effects via stimulation of beta- 1 adrenergic receptors. Cardiac output, oxygen consumption, and the work of the heart may be increased. In the peripheral vasculature, vasoconstriction may occur via stimulation of alpha-1 adrenergic receptors. Palpitations, tachycardia, arrhythmia, hypertension, reflex bradycardia, coronary occlusion, cerebral vasculitis, myocardial infarction, cardiac arrest, and death have been reported. Some of these agents, particularly ephedra alkaloids (ephedrine, ma huang, phenylpropanolamine), may also predispose patients to hemorrhagic and ischemic stroke. Therapy with sympathomimetic agents should generally be avoided or administered cautiously in patients with sensitivity to sympathomimetic amines, hyperthyroidism, or underlying cardiovascular or cerebrovascular disorders. These agents should not be used in patients with severe coronary artery disease or severe/uncontrolled hypertension.

Infection

Moderate:

ozanimod

Ozanimod has a moderate potential interaction with Infection.

Ozanimod may increase the risk of infections and some serious infections with opportunistic pathogens including viruses have been reported. Because of reversible sequestration of lymphocytes in lymphoid tissues, this drug causes a mean reduction in peripheral blood lymphocyte count to approximately 45% of baseline values. Prior to treatment, a recent CBC (i.e., within 6 months or after discontinuation of prior therapy), including lymphocyte count must be available. It is recommended to delay treatment initiation in patients with an active infection until complete resolution. Consider withholding or discontinuing treatment if a patient develops a serious infection, and reassess the benefits and risks prior to reinitiating therapy.

Liver Disease

Major:

Cough & Cold Relief

The acetaminophen in Cough & Cold Relief has a major potential interaction with Liver Disease.

Acetaminophen is contraindicated in patients with severe hepatic impairment or severe active liver disease. Patients with hepatic impairment may be at increased risk of toxicity. Severe liver injury, including cases of acute liver failure and death, have been reported in patients using this drug. Clinical monitoring of hepatic function is recommended. Caution is advised if using acetaminophen in patients with chronic malnutrition or severe hypovolemia. Instruct patients to avoid drinking alcohol while taking acetaminophen-containing medications. Patients should be warned not to exceed the maximum recommended total daily dosage of acetaminophen (4 g/day in adults and children 12 years of age or older), and to read all prescription and over-the-counter medication labels to ensure they are not taking multiple acetaminophen-containing products, or check with a healthcare professional if they are unsure.

Moderate:

ozanimod

Ozanimod has a moderate potential interaction with Liver Disease.

The use of ozanimod may result in elevations of aminotransferases. The use of ozanimod in patients with hepatic impairment is not recommended. While on treatment with this drug, if a patient develop symptoms suggestive of hepatic dysfunction, such as unexplained nausea, vomiting, abdominal pain, fatigue, anorexia, or jaundice and/or dark urine, should have hepatic enzymes checked, and ozanimod should be discontinued if significant liver injury is confirmed.

Macular Edema

Moderate:

ozanimod

Ozanimod has a moderate potential interaction with Macular Edema.

Macular edema has been reported with the use of sphingosine 1-phosphate (S1P) receptor modulators. Care should be exercised when using these drugs in patients with a history of uveitis and patients with diabetes mellitus as these patients are at increased risk for macular edema. Before starting treatment with these agents, an ophthalmic evaluation of the fundus, including the macula, is recommended in all patients and at any time if vision change is reported during treatment. Patients with a history of uveitis and patients with diabetes mellitus should have regular follow-up examinations of the fundus, including the macula during treatment. Continuation of therapy in patients with macular edema has not been evaluated, therefore, a decision on whether or not to discontinue treatment needs to take into account the potential benefits and risks for the individual patients.

Malnourishment

Major:

Cough & Cold Relief

The acetaminophen in Cough & Cold Relief has a major potential interaction with Malnourishment.

Acetaminophen is contraindicated in patients with severe hepatic impairment or severe active liver disease. Patients with hepatic impairment may be at increased risk of toxicity. Severe liver injury, including cases of acute liver failure and death, have been reported in patients using this drug. Clinical monitoring of hepatic function is recommended. Caution is advised if using acetaminophen in patients with chronic malnutrition or severe hypovolemia. Instruct patients to avoid drinking alcohol while taking acetaminophen-containing medications. Patients should be warned not to exceed the maximum recommended total daily dosage of acetaminophen (4 g/day in adults and children 12 years of age or older), and to read all prescription and over-the-counter medication labels to ensure they are not taking multiple acetaminophen-containing products, or check with a healthcare professional if they are unsure.

Multiple Sclerosis

Moderate:

ozanimod

Ozanimod has a moderate potential interaction with Multiple Sclerosis.

Rare cases of severe exacerbation of multiple sclerosis (MS), including disease rebound, have been reported after discontinuation of sphingosine 1-phosphate receptor modulator in MS treated patients. The possibility of severe exacerbation of disease should be considered after stopping treatment with these agents. Patients should be observed for a severe increase in disability upon discontinuation and appropriate treatment should be instituted, as required.

Phenylketonuria

Moderate:

Cough & Cold Relief

The acetaminophen in Cough & Cold Relief has a moderate potential interaction with Phenylketonuria.

Several oral acetaminophen and acetaminophen-combination products, particularly flavored chewable tablets, contain the artificial sweetener, aspartame (NutraSweet). Aspartame is converted to phenylalanine in the gastrointestinal tract following ingestion. Chewable and effervescent formulations of acetaminophen products may also contain phenylalanine. The aspartame/phenylalanine content should be considered when these products are used in patients who must restrict their intake of phenylalanine (i.e. phenylketonurics).

Ozanimod has a moderate potential interaction with Uveitis.

Macular edema has been reported with the use of sphingosine 1-phosphate (S1P) receptor modulators. Care should be exercised when using these drugs in patients with a history of uveitis and patients with diabetes mellitus as these patients are at increased risk for macular edema. Before starting treatment with these agents, an ophthalmic evaluation of the fundus, including the macula, is recommended in all patients and at any time if vision change is reported during treatment. Patients with a history of uveitis and patients with diabetes mellitus should have regular follow-up examinations of the fundus, including the macula during treatment. Continuation of therapy in patients with macular edema has not been evaluated, therefore, a decision on whether or not to discontinue treatment needs to take into account the potential benefits and risks for the individual patients.

Vaccination

Moderate:

ozanimod

Ozanimod has a moderate potential interaction with Vaccination.

Vaccinations may be less effective if administered during ozanimod treatment. Patients without a clinical confirmed history of chickenpox or without documentation of a full course of vaccination against VZV should be tested for antibodies to VZV before initiating treatment. It is recommended to obtain a full course of vaccination for antibody-negative patients with varicella vaccine prior to starting treatment with ozanimod and to postpone treatment for 4 weeks to allow the full effect of vaccination. If live attenuated vaccine immunizations are required, administer at least 1 month prior to initiation of ozanimod.
