Interactions between your drugs

Moderate

chlorpheniramine carbetapentane

Applies to: Tustan 12S (carbetapentane / chlorpheniramine) and Tustan 12S (carbetapentane / chlorpheniramine)

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.

Moderate

chlorpheniramine tirzepatide

Applies to: Tustan 12S (carbetapentane / chlorpheniramine) and tirzepatide

MONITOR: Additive increases in heart rate may occur when tirzepatide is coadministered with other drugs that can also increase heart rate. The mechanism by which tirzepatide may affect heart rate is unknown. In placebo-controlled trials, treatment with tirzepatide resulted in an average increase in heart rate of 2 to 4 beats per minute (bpm) compared to an average increase of 1 bpm in patients receiving placebo. The incidence of patients who had a change in heart rate of greater than 20 bpm from baseline for 2 or more consecutive visits was 2.1%, 3.8% and 2.9% for tirzepatide 5 mg, 10 mg and 15 mg, respectively, compared with 2.1% for placebo. Episodes of sinus tachycardia, associated with a concomitant increase in heart rate of greater than or equal to 15 bpm from baseline, were reported in 4.3%, 4.6%, 5.9% and 10% of subjects treated with placebo or tirzepatide 5 mg, 10 mg and 15 mg, respectively. For patients enrolled in Japan, the reported frequencies of these episodes were 7% (3/43), 7.1% (3/42), 9.3% (4/43) and 23% (10/43), respectively.

MANAGEMENT: Although the clinical relevance of the effects on heart rate is not currently known, some authorities suggest observing caution when tirzepatide is coadministered with other drugs that can increase heart rate such as those with sympathomimetic or anticholinergic activity. Advise patients of the potential risk of tachycardia and to contact their healthcare provider if it occurs in the absence of a known cause (i.e., at rest).

Drug and food interactions

Moderate

chlorpheniramine food

Applies to: Tustan 12S (carbetapentane / chlorpheniramine)

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.

tirzepatide food

Applies to: tirzepatide

MONITOR: Glucagon-like peptide-1 (GLP-1) receptor agonists and dual GLP-1 and glucose-dependent insulinotropic polypeptide (GIP) receptor agonists can delay gastric emptying, which may impact the absorption of concomitantly administered oral medications. Mild to moderate decreases in plasma concentrations of coadministered drugs have been demonstrated in pharmacokinetic studies for some GLP-1 receptor agonists (e.g., exenatide, lixisenatide), but not others. According to the prescribing information, liraglutide did not affect the absorption of several orally administered drugs to any clinically significant extent, including acetaminophen, atorvastatin, digoxin, griseofulvin, lisinopril, and an oral contraceptive containing ethinyl estradiol-levonorgestrel. Likewise, no clinically relevant effect on absorption was observed for concomitantly administered oral drugs studied with albiglutide (digoxin, ethinyl estradiol-norethindrone, simvastatin, warfarin), dulaglutide (acetaminophen, atorvastatin, digoxin, ethinyl estradiol-norelgestromin, lisinopril, metformin, metoprolol, sitagliptin, warfarin), or semaglutide (atorvastatin, digoxin, ethinyl estradiol-levonorgestrel, metformin, warfarin). The impact of dual GLP-1 and GIP receptor agonist tirzepatide on gastric emptying was reported to be dose- and time-dependent, with the greatest effect observed after a single 5 mg dose but diminished after subsequent doses. When acetaminophen was administered following a single 5 mg dose of tirzepatide, acetaminophen peak plasma concentration (Cmax) was decreased by 50% and its median time to peak plasma concentration (Tmax) delayed by 1 hour. However, no significant impact on acetaminophen Cmax and Tmax was observed after 4 consecutive weekly doses of tirzepatide (5 mg/5 mg/8 mg/10 mg), and the overall exposure (AUC) of acetaminophen was unaffected. Tirzepatide at lower doses of 0.5 mg and 1.5 mg also had minimal effects on acetaminophen exposure.

MANAGEMENT: Although no specific dosage adjustment of concomitant medications is generally recommended based on available data, potential clinical impact on some oral medications cannot be ruled out, particularly those with a narrow therapeutic index or low bioavailability, those that depend on threshold concentrations for efficacy (e.g., antibiotics), and those that require rapid gastrointestinal absorption (e.g., hypnotics, analgesics). Pharmacologic response to concomitantly administered oral medications should be monitored more closely following initiation, dose adjustment, or discontinuation of a GLP-1 receptor agonist or a dual GLP-1 and GIP receptor agonist.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
