Iren can interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid): - CYP3A4 inducers (e.g., rifampin, carbamazepine): reduce contraceptive effectiveness. - Antifungal agents (e.g., ketoconazole, itraconazole): increase hormone levels, raising side‑effect risk. - St. John’s wort: may diminish contraceptive protection. - Certain antibiotics (e.g., griseofulvin): may lower plasma hormone concentrations.

Moderate Interactions (Monitor Closely): - SSRIs (e.g., fluoxetine): may increase bleeding tendency. - Antihypertensives (e.g., ACE inhibitors): monitor blood pressure for additive effects. - Antidiabetic drugs (e.g., metformin): observe glucose control as hormones can affect insulin sensitivity.
