Understanding Viagra: Uses, Benefits, and Considerations
Viagra, known generically as sildenafil, is a widely recognized medication used to treat erectile dysfunction (ED) in men. Since its introduction in the late 1990s, it has become a cornerstone in the management of impotence, helping millions regain their confidence and improve their quality of life.
What is Viagra?
Viagra is a prescription drug that belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors. It works by increasing blood flow to the penis, helping men achieve and maintain an erection when sexually stimulated. It is important to note that Viagra does not cure ED or increase sexual desire; it only works when there is sexual arousal.
How Does Viagra Work?
Viagra functions by inhibiting the PDE5 enzyme, which leads to the relaxation of blood vessels in the penis and increased blood flow. This process requires sexual arousal to be effective, as it relies on the natural release of nitric oxide in the body.
Indications for Use
- Erectile Dysfunction (ED): Primarily used to treat impotence in men.
- Pulmonary Arterial Hypertension: In some cases, Viagra is also prescribed to improve exercise capacity in both men and women by relaxing blood vessels in the lungs.
Viagra Dosages and Administration
The typical starting dose for Viagra is 50 mg, taken as needed approximately one hour before sexual activity. Depending on effectiveness and tolerability, the dosage may be increased to 100 mg or decreased to 25 mg. It is crucial not to take Viagra more than once a day. Always follow your healthcare provider’s instructions and never self-adjust the dosage.
Possible Side Effects
Like all medications, Viagra can cause side effects. Common reactions include:
- Headache
- Flushing
- Upset stomach
- Nasal congestion
- Dizziness
In rare cases, more severe side effects may occur, such as vision changes or an erection lasting more than four hours (priapism). If you experience these, seek medical attention immediately.
