Sudden death and QT prolongation have occurred in patients receiving nilotinib therapy. Also, nilotinib is a moderate CYP3A4 inhibitor and vardenafil is a primary CYP3A4 substrate; administering these drugs together levitra 10mg tablets may result in increased vardenafil concentrations. Do not use vardenafil orally disintegrating tablets with nilotinib due to increased vardenafil exposure.
- Levitra does not cure erectile dysfunction; it manages symptoms.
- Combining Levitra with certain antibiotics or antifungals may alter its effectiveness.
- Always follow the healthcare provider’s instructions for dosage and timing.
- Levitra is usually taken without regard to meals, but high-fat meals may delay action.
- Patients should report any allergic reactions such as rash or swelling.
- Use with caution in patients already taking blood pressure medications.
- Men with history of stroke or heart attack should consult a doctor before use.

If use of nilotinib and vardenafil oral tablets is required, do not exceed a single vardenafil oral tablet dose of 5 mg per 24-hour period.
Warnings & Precautions
Vardenafil is a primary CYP3A4 substrate that is associated with QT prolongation. Both therapeutic and supratherapeutic doses of vardenafil can produce an increase in QTc interval. Lefamulin is a moderate CYP3A4 inhibitor that has a concentration-dependent QTc prolongation effect. Coadministration of vardenafil with another moderate CYP3A4 inhibitor increased the AUC of vardenafil by 4-fold. Lenacapavir: (Major) Do not use vardenafil orally disintegrating tablets with lenacapavir due to increased vardenafil exposure; do not exceed a single dose of 5 mg per 24-hour period of vardenafil oral tablets.
How does vardenafil work (mechanism of action)?
Vardenafil is primarily metabolized by CYP3A; lenacapavir is a moderate CYP3A inhibitor. Lenvatinib: (Major) Concomitant use of vardenafil and lenvatinib increases the risk of QT/QTc prolongation and torsade de pointes (TdP). Letermovir: (Major) Do not use vardenafil orally disintegrating tablets with letermovir due to increased vardenafil exposure; do not exceed a single dose of 5 mg per 24-hour period of vardenafil oral tablets. Vardenafil is primarily metabolized by CYP3A4/5; letermovir is a moderate CYP3A4 inhibitor. Leuprolide: (Moderate) Concomitant use of vardenafil and androgen deprivation therapy (i.e., leuprolide) may increase the risk of QT/QTc prolongation and torsade de pointes (TdP) in some patients.
