Marvelon can interact with several medicines, altering its effectiveness or safety profile.

Major Interactions (Avoid): - Enzyme‑inducing anticonvulsants (e.g., carbamazepine, phenytoin): may markedly reduce contraceptive efficacy. - Rifampin or rifabutin: strong hepatic enzyme inducers that lower hormone levels. - Certain antiretrovirals (e.g., efavirenz): can diminish contraceptive protection.

Moderate Interactions (Monitor Closely): - Antibiotics such as tetracycline or fluoroquinolones: may slightly decrease effectiveness. - Antifungal agents (e.g., ketoconazole, itraconazole): can increase hormone concentrations, raising side‑effect risk. - St. John’s wort: herbal inducer that may lower plasma hormone levels.
