Before prescribing Levitra, consider the following precautions: - Cardiovascular assessment: evaluate for recent heart attack, unstable angina, or uncontrolled hypertension. - Nitrate contraindication: do not combine with nitrates or nitric‑oxide donors due to risk of severe hypotension. - Liver impairment: use with caution in patients with severe hepatic dysfunction; dose adjustment may be required. - Visual disturbances: advise patients to report sudden loss of vision or changes in color perception promptly. - Store at below 25°C: keep tablets in the original container, protect from moisture and direct sunlight.

Levitra may interact with several medicines. Review patient medication lists carefully.

Major Interactions (Avoid): - Nitrates: concurrent use can cause profound hypotension. - Alpha‑blockers: may lead to additive blood pressure lowering effects. - Protease inhibitors (e.g., ritonavir): increase vardenafil plasma levels, raising risk of adverse events.

Moderate Interactions (Monitor Closely): - Antihypertensive agents: may enhance blood pressure‑lowering effect; monitor blood pressure. - CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): can raise vardenafil concentrations; dose adjustment may be needed.
