What is Viagra?
Viagra, known generically as Sildenafil, is a medication primarily used to treat erectile dysfunction (ED) in men. Developed and manufactured by Pfizer, it is part of a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. Originally intended to treat hypertension and angina, Viagra found its niche in addressing erectile issues.
How Does Viagra Work?
The mechanism of action for Viagra involves enhancing the effects of nitric oxide, a natural chemical in the body that relaxes muscles in the penis. This results in increased blood flow and an erection in response to sexual stimulation. By inhibiting the PDE5 enzyme, Viagra helps maintain an erection that is harder and longer-lasting.
Indications for Use
- Primarily prescribed for erectile dysfunction.
- Sometimes used for the treatment of pulmonary arterial hypertension under the brand name Revatio.
- Off-label uses include Raynaud’s phenomenon and other circulatory issues as directed by a healthcare provider.
How to Use Viagra Safely
To ensure the effectiveness and safety of Viagra, follow these recommendations:
- Consult a healthcare professional before starting Viagra, especially if you have underlying health conditions or are taking other medications.
- Take the medication approximately 30-60 minutes before planned sexual activity.
- Viagra can be taken with or without food, but high-fat meals may delay its effect.
- Do not take more than one dose in a 24-hour period.
- Avoid alcohol as it can increase the risk of side effects.
Possible Side Effects
While Viagra is effective for many, some users may experience side effects, which can include:
- Headaches
- Flushing
- Upset stomach
- Vision changes
- Back pain
If you experience severe side effects, such as chest pain or a prolonged erection lasting more than four hours, seek medical attention immediately.
