Leverette 21 can interact with other medicines, altering its effectiveness or safety profile.

Major Interactions (Avoid): - Enzyme‑inducing anticonvulsants (e.g., carbamazepine, phenytoin): reduce contraceptive efficacy. - Rifampicin and other rifamycins: markedly decrease hormone levels. - Protease inhibitors (e.g., ritonavir): increase risk of hormonal side effects. - St John’s wort: may lower contraceptive effectiveness. - Certain antiretrovirals (e.g., efavirenz): diminish hormone exposure.

Moderate Interactions (Monitor Closely): - Antifungal agents (e.g., ketoconazole): may increase hormone concentrations. - SSRIs (e.g., fluoxetine): possible alteration of bleeding patterns. - Antihypertensives (e.g., beta‑blockers): monitor blood pressure changes. - Diuretics: may affect electrolyte balance and blood pressure. - Herbal supplements (e.g., ginseng): observe for reduced contraceptive reliability.
