Understanding Viagra: A Comprehensive Guide
What is Viagra?
Viagra, known generically as sildenafil, is a medication primarily used to treat erectile dysfunction (ED) in men. First approved by the FDA in 1998, Viagra has since become one of the most well-known treatments for this condition, helping millions of men around the world restore their sexual function.
Mechanism of Action
Viagra works by inhibiting an enzyme known as phosphodiesterase type 5 (PDE5). This action results in the relaxation of smooth muscle and an increase in blood flow to the penis, which facilitates the achievement and maintenance of an erection when combined with sexual stimulation.
Indications for Use
Viagra is primarily indicated for the treatment of erectile dysfunction, a condition characterized by the inability to achieve or maintain an erection sufficient for satisfactory sexual intercourse. It is important to note that Viagra does not cure ED or increase sexual desire.
How to Use Viagra
Viagra is typically taken orally, as needed, approximately 30 minutes to one hour before sexual activity. It is important not to take more than one dose in a 24-hour period. For the best results, Viagra should be taken on an empty stomach, as high-fat meals can delay its effectiveness.
Possible Side Effects
- Headache
- Flushing
- Upset stomach
- Abnormal vision (such as changes in color vision)
- Nasal congestion
- Back pain
- Muscle pain
- Nausea
- Dizziness
- Rash
If you experience severe side effects such as chest pain, sudden vision loss, or an erection lasting more than four hours, seek medical attention immediately.
