The typical starting dose of Viagra is 50 mg taken orally, about one hour before sexual activity. Your doctor might recommend 25 mg for those starting treatment or with certain health conditions. The maximum recommended dose is 100 mg per day.
Always take Viagra as directed by your physician. Do not exceed the recommended dosage. Swallow the tablet whole with a glass of water. Viagra’s effects generally last for four to five hours.
Several medications can interact negatively with Viagra. It’s crucial to inform your doctor about all medications you are currently taking, including:
- Nitrates: Combining Viagra with nitrates (used to treat chest pain) can cause a dangerous drop in blood pressure. Alpha-blockers: These medications (used to treat high blood pressure and enlarged prostate) can also lower blood pressure when taken with Viagra. Certain antifungals: Some antifungal medications can interact with Viagra, potentially increasing its side effects. HIV protease inhibitors: These medications can increase Viagra’s concentration in the blood. Other ED medications: Never take Viagra with other phosphodiesterase-5 (PDE5) inhibitors like Cialis or Levitra.
Grapefruit juice can also interact with Viagra. Avoid consuming grapefruit or grapefruit juice while taking this medication.
If you experience side effects such as chest pain, prolonged erection (priapism), sudden vision loss, or hearing loss, seek immediate medical attention.
