What is Viagra and how does it work?
Viagra (sildenafil) is a medication used to treat erectile dysfunction. It works by relaxing blood vessel walls and increasing blood flow to the penis, helping a man achieve and maintain an erection when sexually stimulated. Viagra was invented in the early 1990s and has been used for ED treatment since 1998.
What dosage options are available?
Viagra is commonly available in 50 mg and 100 mg tablets. The appropriate dosage depends on individual health factors and should be determined by a doctor. It is important to follow the prescribed dosage exactly and not exceed one dose per day.
What are the common side effects?
Common side effects may include headache, flushing, nasal congestion, upset stomach, and dizziness. Most side effects are mild and temporary. Serious side effects are rare but require immediate medical attention — these include sudden vision or hearing loss and chest pain.
Can Viagra interact with other medications?
Yes. Viagra can interact with nitrates (often prescribed for chest pain), certain blood pressure medications, and some antifungal or antibiotic drugs. Always inform your doctor about all medications you are taking before using Viagra.
Is generic Viagra the same as brand-name Viagra?
Generic Viagra contains the same active ingredient — sildenafil citrate — as the brand-name product. It is designed to work the same way in the body. Generic versions are typically available at lower cost, and several manufacturers produce sildenafil citrate tablets, including Cipla (marketed as Suhagra).
Can women use Viagra or similar medications?
Viagra is not approved for use in women. However, sildenafil citrate (the active ingredient in Viagra) is sometimes prescribed for pulmonary arterial hypertension in both men and women. There are also separate medications, such as Lovegra, designed specifically for female sexual health concerns.
How should I take Viagra?
Take Viagra approximately 30 to 60 minutes before sexual activity. It can be taken with or without food, though a heavy or high-fat meal may delay its effect. Sexual stimulation is required for the medication to work. Do not take more than one dose in a 24-hour period.
