Drug interactions
Moderate drug interactions
Moderate:
pseudoephedrine milnacipran
Applies to: Actifed (pseudoephedrine / triprolidine) and milnacipran
Monitor
Additive or synergistic effects on blood pressure and heart rate may occur when serotonin-norepinephrine reuptake inhibitors (SNRIs) are combined with sympathomimetic agents such as nasal decongestants, adrenergic bronchodilators, ophthalmic vasoconstrictors, and systemic vasopressors. The use of SNRIs alone has been associated with sustained increases in blood pressure and heart rate, and cases of elevated blood pressure requiring immediate treatment have been reported in postmarketing experience.
Management
Caution is advised if SNRIs are used with other drugs that can increase blood pressure and/or heart rate. Blood pressure and pulse should be measured prior to initiating SNRI therapy and monitored at regular intervals thereafter. Dose reduction or discontinuation of the SNRI should be considered in patients who experience a sustained increase in blood pressure or pulse rate.

Moderate:
triprolidine Food/Lifestyle
Applies to: Actifed (pseudoephedrine / triprolidine)
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.

Moderate:
milnacipran Food/Lifestyle
Applies to: milnacipran
Generally avoid
Use of milnacipran in conjunction with chronic alcohol consumption may potentiate the risk of liver injury. Milnacipran alone can increase serum transaminase levels. In placebo-controlled fibromyalgia trials, increases in ALT were more frequently observed in patients treated with milnacipran 100 mg/day (6%) and 200 mg/day (7%) compared to patients treated with placebo (3%). One patient receiving milnacipran 100 mg/day (0.2%) had an increase in ALT greater than 5 times the upper limit of normal (ULN) but did not exceed 10 times the ULN. Increases in AST were also more frequently observed in patients treated with milnacipran 100 mg/day (3%) and 200 mg/day (5%) than in patients treated with placebo (2%). There have been reported cases of increased liver enzymes and severe liver injury, including fulminant hepatitis, from foreign postmarketing experience with milnacipran. Significant underlying clinical conditions and/or use of multiple concomitant medications were present in the cases of severe liver injury.
Management
Due to the risk of liver injury, patients prescribed milnacipran should be counseled to avoid excessive use of alcohol. Milnacipran should generally not be prescribed to patients with substantial alcohol use.

pseudoephedrine Caffeine
Applies to: Actifed (pseudoephedrine / triprolidine)
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.

Bipolar Disorder
Major:
milnacipran
Milnacipran has a major potential interaction with Bipolar Disorder.
Adult and pediatric patients with depression and other psychiatric disorders may experience worsening of their symptoms and may have the emergence of suicidal thoughts and behavior. Patients should be monitored appropriately and observed closely for worsening of their symptoms, suicidality or changes in their behavior, especially during the first few months of treatment, and at times of dose changes. Discontinuing the medication should be considered if symptoms are persistently worse, or abrupt in onset. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Moderate:
milnacipran
Milnacipran has a moderate potential interaction with Bipolar Disorder.
Therapy with SNRI antidepressants can cause activation of mania and hypomania and should be used with caution in patients with personal or family history of mania, hypomania, bipolar disorder, and other mood disorders.
Cardiovascular Conditions and Disorders
Major:
Actifed
The pseudoephedrine in Actifed 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.
Moderate:
Actifed
The triprolidine in Actifed has a moderate potential interaction with Cardiovascular Conditions and Disorders.
Antihistamines may infrequently cause cardiovascular adverse effects related to their anticholinergic and local anesthetic (quinidine-like) activities. Tachycardia, palpitation, ECG changes, arrhythmias, hypotension, and hypertension have been reported. Although these effects are uncommon and usually limited to overdosage situations, the manufacturers and some clinicians recommend that therapy with antihistamines be administered cautiously in patients with cardiovascular disease, hypertension, and/or hyperthyroidism.
Cerebrovascular Insufficiency

Some manufacturers and clinicians recommend that therapy with antihistamines be administered cautiously in patients with asthma or chronic obstructive pulmonary disease.
Dehydration
Moderate:
milnacipran
Milnacipran has a moderate potential interaction with Dehydration.
Treatment with SNRI antidepressants can cause hyponatremia. Caution should be used when treating patients with hyponatremia or at greater risk of hyponatremia such as the elderly, patients taking diuretics or who are volume depleted.
Depression
Major:
milnacipran
Milnacipran has a major potential interaction with Depression.
Adult and pediatric patients with depression and other psychiatric disorders may experience worsening of their symptoms and may have the emergence of suicidal thoughts and behavior. Patients should be monitored appropriately and observed closely for worsening of their symptoms, suicidality or changes in their behavior, especially during the first few months of treatment, and at times of dose changes. Discontinuing the medication should be considered if symptoms are persistently worse, or abrupt in onset. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Diabetes Mellitus
Moderate:
Actifed
The pseudoephedrine in Actifed 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.
Gastrointestinal Obstruction
Moderate:
Actifed
The pseudoephedrine in Actifed has a moderate potential interaction with Gastrointestinal Obstruction.
The extended-release formulation of pseudoephedrine (Sudafed 24 Hour) contains a non-deformable material. There have been rare reports of obstructive symptoms in patients with known strictures following the ingestion of similar sustained-release products. Therapy with the extended-release formulation of pseudoephedrine should be administered cautiously in patients with preexisting severe gastrointestinal narrowing or obstruction, whether pathologic or iatrogenic.
Moderate:
Actifed
The triprolidine in Actifed has a moderate potential interaction with Gastrointestinal Obstruction.
Antihistamines often have anticholinergic activity, to which elderly patients are particularly sensitive. Therapy with antihistamines should be administered cautiously, if at all, in patients with preexisting conditions that are likely to be exacerbated by anticholinergic activity, such as urinary retention or obstruction; angle-closure glaucoma, untreated intraocular hypertension, or uncontrolled primary open-angle glaucoma; and gastrointestinal obstructive disorders. Conventional, first-generation antihistamines such as the ethanolamines (bromodiphenhydramine, carbinoxamine, clemastine, dimenhydrinate, diphenhydramine, doxylamine, phenyltoloxamine) tend to exhibit substantial anticholinergic effects. In contrast, the newer, relatively nonsedating antihistamines (e.g., cetirizine, fexofenadine, loratadine) reportedly have low to minimal anticholinergic activity at normally recommended dosages and may be appropriate alternatives.
Glaucoma, Narrow Angle
Moderate:
milnacipran
Milnacipran has a moderate potential interaction with Glaucoma, Narrow Angle.
SNRI antidepressants cause pupillary dilation that may trigger an angle closure attack in patients with anatomically narrow angle without iridectomy.
Glaucoma/Intraocular Hypertension
Moderate:
Actifed
The triprolidine in Actifed has a moderate potential interaction with Glaucoma/Intraocular Hypertension.
Antihistamines often have anticholinergic activity, to which elderly patients are particularly sensitive.

Moderate:
Actifed
The pseudoephedrine in Actifed 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.
High Blood Pressure
Moderate:
milnacipran
Milnacipran has a moderate potential interaction with High Blood Pressure.
Selective serotonin and norepinephrine reuptake inhibitor antidepressants (SNRIs) have been associated with sustained increases in blood pressure.

Liver Disease
Major:
milnacipran
Milnacipran has a major potential interaction with Liver Disease.
Postmarketing studies have reported that duloxetine and some other SNRIs like milnacipran may aggravate preexisting liver disease. The use of duloxetine delayed-release and milnacipran should be avoided in patients with chronic liver disease or cirrhosis.
Moderate:
Actifed
The triprolidine in Actifed has a moderate potential interaction with Liver Disease.
Limited pharmacokinetic data are available for the older, first-generation antihistamines. Many appear to be primarily metabolized by the liver, and both parent drugs and metabolites are excreted in the urine. Patients with renal and/or liver disease may be at greater risk for adverse effects from antihistamines due to drug and metabolite accumulation. Therapy with antihistamines should be administered cautiously in such patients. Lower initial dosages may be appropriate.
Mania
Moderate:
