Myrzi (Desogestrel, Ethinylestradiol)

Desogestrel/Ethinylestradiol, the active ingredients in Myrzi, are a combined oral contraceptive presented as an oral tablet for oral use. They work to prevent pregnancy by inhibiting ovulation and creating cervical mucus changes that reduce fertilisation. Myrzi is prescribed for women of reproductive age seeking reliable hormonal contraception.

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

Major Interactions (Avoid): - Antiepileptic drugs (e.g., carbamazepine, phenytoin): markedly reduce contraceptive efficacy. - Rifampicin and other strong enzyme inducers: may lead to contraceptive failure. - Certain HIV protease inhibitors (e.g., ritonavir): increase risk of thrombotic events.

Moderate Interactions (Monitor Closely): - Antifungal agents (e.g., fluconazole): may increase hormone levels, watch for side‑effects. - Antibiotics (e.g., tetracycline): occasional reduction in contraceptive effect, advise backup method. - St. John’s wort: may lower hormone concentrations, consider alternative contraception.
