Always inform your doctor about all medications you are taking, including over-the-counter drugs, supplements, and herbal remedies. This includes nitrates (used for chest pain), alpha-blockers (used for high blood pressure or enlarged prostate), and certain antifungals. Combining Filitra (vardenafil) with these can cause a dangerous drop in blood pressure.
Specific interactions require careful monitoring. For example, combining vardenafil with ritonavir or indinavir (HIV protease inhibitors) necessitates a lower Filitra dose to prevent adverse effects. Similarly, co-administration with erythromycin or ketoconazole (antifungals) may increase vardenafil’s concentration, potentially leading to side effects.
Grapefruit juice can also interact significantly. Avoid grapefruit juice and grapefruit-containing products while taking Filitra, as it can increase vardenafil levels in your blood.
Alcohol can intensify vardenafil’s side effects, such as dizziness and lightheadedness. Limit or avoid alcohol consumption while using this medication. Your physician can provide personalized advice regarding alcohol intake.
This information is not exhaustive. Consult your doctor or pharmacist for a complete list of potential drug interactions and for personalized guidance.
Discontinue Filitra immediately and seek medical attention if you experience severe side effects, such as chest pain, prolonged erection (priapism), or sudden vision loss.
