Interactions between your drugs

Moderate

naproxen edrophonium

Applies to: EC-Naprosyn (naproxen) and edrophonium

Consumer information for this interaction is not currently available.

MONITOR: The concomitant use of acetylcholinesterase inhibitors (ACHEIs) (e.g., donepezil, galantamine, benzgalantamine physostigmine, rivastigmine, tacrine) with nonsteroidal anti-inflammatory drugs (NSAIDs) may increase the risk of gastrointestinal (GI) bleeding. ACHEIs can increase gastric acid secretion due to their cholinergic effects and NSAIDS may increase the risk of GI bleeding and ulceration. In a Swedish retrospective case study of 70,060 patients aged 65 years and older with new prescriptions for both ACHEIs and NSAIDs, 1500 persons were diagnosed with incident peptic ulcer. The results suggested that the risk of peptic ulcer was significantly increased for the combination of ACHEIs and NSAIDs compared to NSAIDs alone. No increased risks were found for the use of ACHEIs alone.


MANAGEMENT: Caution and clinical monitoring are recommended if concomitant use of ACHEIs and NSAIDs is required, especially in patients with a prior history of peptic ulcer disease, the elderly, or debilitated patients. Patients should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence gastrointestinal bleeding such as black or tarry stools, bright red blood in vomit, coffee ground like vomit, abdominal pain or cramping, diarrhea, dizziness or lightheadedness, weakness or fatigue and pale skin.

Drug and food interactions

Moderate

naproxen food

Applies to: EC-Naprosyn (naproxen)

Ask your doctor before using naproxen together with ethanol (alcohol). Do not drink alcohol while taking naproxen. Alcohol can increase your risk of stomach bleeding caused by naproxen. Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Moderate

naproxen food

Applies to: EC-Naprosyn (naproxen)

Consumer information for this interaction is not currently available.

MONITOR: Smoking cessation may lead to elevated plasma concentrations and enhanced pharmacologic effects of drugs that are substrates of CYP450 1A2 (and possibly CYP450 1A1) and/or certain drugs with a narrow therapeutic index (e.g., flecainide, pentazocine). One proposed mechanism is related to the loss of CYP450 1A2 and 1A1 induction by polycyclic aromatic hydrocarbons in tobacco smoke; when smoking cessation agents are initiated and smoking stops, the metabolism of certain drugs may decrease leading to increased plasma concentrations. The mechanism by which smoking cessation affects narrow therapeutic index drugs that are not known substrates of CYP450 1A2 or 1A1 is unknown. The clinical significance of this interaction is unknown as clinical data are lacking.

MANAGEMENT: Until more information is available, caution is advisable if smoking cessation agents are used concomitantly with drugs that are substrates of CYP450 1A2 or 1A1 and/or those with a narrow therapeutic range. Patients receiving smoking cessation agents may require periodic dose adjustments and closer clinical and laboratory monitoring of medications that are substrates of CYP450 1A2 or 1A1.

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.
