- Strong CYP3A4 inhibitors (for example ritonavir, ketoconazole, itraconazole, erythromycin): these agents can raise sildenafil levels and boost unwanted postmarketing effects; dose adjustments or other possible paths may be needed.
- Strong CYP3A4 inducers (for example rifampicin, phenobarbital): these can reduce sildenafil concentrations and reduce effectiveness.
