Interactions between your drugs

Moderate

interferon alfa-2a moexipril

Applies to: interferon alfa-2a and moexipril

MONITOR: The concomitant use of recombinant interferon-alpha-2a and some angiotensin converting enzyme (ACE) inhibitors has been associated with a higher incidence of granulocytopenia than either drug used alone in patients with cryoglobulinemia. The mechanism is unknown but may be related to an autoimmune response. It is also unknown whether patients with other conditions may be affected. Data exist for enalapril and captopril.

MANAGEMENT: Until more information is available, close hematologic monitoring is recommended.

Drug and food interactions

Moderate

moexipril food

Applies to: moexipril

GENERALLY AVOID: Moderate-to-high dietary intake of potassium can cause hyperkalemia in some patients who are using angiotensin converting enzyme (ACE) inhibitors. In some cases, affected patients were using a potassium-rich salt substitute. ACE inhibitors can promote hyperkalemia through inhibition of the renin-aldosterone-angiotensin (RAA) system.

MANAGEMENT: It is recommended that patients who are taking ACE inhibitors be advised to avoid moderately high or high potassium dietary intake. Particular attention should be paid to the potassium content of salt substitutes.

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.
