Interactions between your drugs

Moderate

chlorpheniramine dextromethorphan

Applies to: Triaminic-D Multi-Symptom Cold (chlorpheniramine / dextromethorphan / pseudoephedrine) and Triaminic-D Multi-Symptom Cold (chlorpheniramine / dextromethorphan / pseudoephedrine)

MONITOR: Central nervous system- and/or respiratory-depressant effects may be additively or synergistically increased in patients taking multiple drugs that cause these effects, especially in elderly or debilitated patients. Sedation and impairment of attention, judgment, thinking, and psychomotor skills may increase.

MANAGEMENT: During concomitant use of these drugs, patients should be monitored for potentially excessive or prolonged CNS and respiratory depression. Cautious dosage titration may be required, particularly at treatment initiation. Ambulatory patients should be counseled to avoid hazardous activities requiring 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.

pseudoephedrine lixisenatide

Applies to: Triaminic-D Multi-Symptom Cold (chlorpheniramine / dextromethorphan / pseudoephedrine) and lixisenatide

MONITOR: The efficacy of insulin and other antidiabetic agents may be diminished by certain drugs, including atypical antipsychotics, corticosteroids, diuretics, estrogens, gonadotropin-releasing hormone agonists, human growth hormone, phenothiazines, progestins, protease inhibitors, sympathomimetic amines, thyroid hormones, L-asparaginase, alpelisib, copanlisib, danazol, diazoxide, isoniazid, megestrol, omacetaxine, phenytoin, sirolimus, tagraxofusp, temsirolimus, as well as pharmacologic dosages of nicotinic acid and adrenocorticotropic agents. These drugs may interfere with blood glucose control because they can cause hyperglycemia, glucose intolerance, new-onset diabetes mellitus, and/or exacerbation of preexisting diabetes.

MANAGEMENT: Caution is advised when drugs that can interfere with glucose metabolism are prescribed to patients with diabetes. Close clinical monitoring of glycemic control is recommended following initiation or discontinuation of these drugs, and the dosages of concomitant antidiabetic agents adjusted as necessary. Patients should be advised to notify their physician if their blood glucose is consistently high or if they experience symptoms of severe hyperglycemia such as excessive thirst and increases in the volume or frequency of urination. Likewise, patients should be observed for hypoglycemia when these drugs are withdrawn from their therapeutic regimen.

Drug and food interactions

Moderate

chlorpheniramine food

Applies to: Triaminic-D Multi-Symptom Cold (chlorpheniramine / dextromethorphan / pseudoephedrine)

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.

lixisenatide food

Applies to: lixisenatide

ADJUST DOSING INTERVAL: Lixisenatide slows gastric emptying, which may impact the absorption of concomitantly administered oral medications. The interaction has been studied with various medications, which demonstrated primarily an effect on the rate rather than the overall extent of absorption.

Acetaminophen: When acetaminophen 1000 mg was administered 1 hour and 4 hours after lixisenatide 10 mcg injection, acetaminophen peak plasma concentration (Cmax) was decreased by 29% and 31%, respectively; and median time to peak plasma concentration (Tmax) was delayed by 2 hours and 1.75 hours, respectively. The Cmax and Tmax of acetaminophen were not significantly altered when acetaminophen was given one hour before lixisenatide injection, and systemic exposure (AUC) was not affected whether administered before or after lixisenatide administration. Based on these results, no dose adjustment for acetaminophen is required; however, it may be advisable to take acetaminophen at least one hour before lixisenatide if a rapid onset of action is required.

Oral Contraceptives: When an oral contraceptive containing ethinyl estradiol 0.03 mg and levonorgestrel 0.15 mg was administered 1 hour and 4 hours after lixisenatide 10 mcg injection, ethinyl estradiol Cmax was decreased by 52% and 39%, respectively, while levonorgestrel Cmax was decreased by 46% and 20%, respectively. Median Tmax values were delayed by 1 to 3 hours, but overall exposure (AUC) and mean terminal half-life (T1/2) of ethinyl estradiol and levonorgestrel were not significantly altered. Administration of the oral contraceptive 1 hour before or 11 hours after lixisenatide had no effect on any of the measured pharmacokinetic parameters of either ethinyl estradiol or levonorgestrel. Based on these results, no dose adjustment for oral contraceptives is required; however, some authorities recommend that oral contraceptives be administered at least 1 hour before or 11 hours after lixisenatide.

Atorvastatin: When atorvastatin 40 mg and lixisenatide 20 mcg were coadministered in the morning for 6 days, atorvastatin Cmax was decreased by 31% and Tmax was delayed by 3.25 hours, but AUC was not affected. When atorvastatin was administered in the evening and lixisenatide in the morning, the AUC and Cmax of atorvastatin were increased by 27% and 66%, respectively, but there was no change in Tmax. Based on these results, no dose adjustment for atorvastatin is required; however, some authorities recommend that atorvastatin be administered at least 1 hour before lixisenatide.

Warfarin: When warfarin 25 mg was coadministered with repeated dosing of lixisenatide 20 mcg, warfarin Cmax was decreased by 19% and Tmax was delayed by 7 hours, but there were no effects on AUC or International Normalized Ratio (INR). Based on these results, no dose adjustment for warfarin is required; however, closer monitoring of INR may be appropriate following initiation or discontinuation of lixisenatide treatment.

Digoxin: When digoxin 0.25 mg and lixisenatide 20 mcg were coadministered at steady state, digoxin Cmax was decreased by 26% and Tmax was delayed by 1.5 hours, but AUC was not affected. Based on these results, no dose adjustment for digoxin is required.

Ramipril: When ramipril 5 mg and lixisenatide 20 mcg were coadministered for 6 days, ramipril Cmax was decreased by 63% and AUC was increased by 21%, while Cmax and AUC of the active metabolite (ramiprilat) were not affected. The Tmax values of ramipril and ramiprilat were delayed by approximately 2.5 hours. Based on these results, no dose adjustment for ramipril is required.

MANAGEMENT: Caution is advised during concomitant use of lixisenatide with oral medications that have a narrow therapeutic index or that require careful clinical monitoring. These medications should be administered on a consistent schedule relative to lixisenatide, and blood levels and/or pharmacologic effects should be closely monitored. In addition, if they are to be administered with food, patients should be advised to take them with a meal or snack when lixisenatide is not administered. Oral medications that are particularly dependent on threshold concentrations for efficacy, such as antibiotics, or medications for which a delay in effect is undesirable, such as acetaminophen, should be administered at least 1 hour before lixisenatide. Gastro-resistant formulations containing substances sensitive to stomach degradation should be administered 1 hour before or 4 hours after lixisenatide. Patients taking oral contraceptives should be advised to take them at least 1 hour before or 11 hours after lixisenatide.

pseudoephedrine food

Applies to: Triaminic-D Multi-Symptom Cold (chlorpheniramine / dextromethorphan / pseudoephedrine)

MONITOR: Coadministration of two or more sympathomimetic agents may increase the risk of adverse effects such as nervousness, irritability, and increased heart rate. Central nervous system (CNS) stimulants, particularly amphetamines, can potentiate the adrenergic response to vasopressors and other sympathomimetic agents. 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 agents are coadministered. Pulse and blood pressure should be closely monitored.
