What It Is and How It Works
Viagra is a medication used primarily to treat erectile dysfunction. It functions by relaxing muscles in the walls of blood vessels and increasing blood flow to particular areas of the body, most notably the penis. Viagra achieves its effects by inhibiting an enzyme called phosphodiesterase type 5 (PDE5). By blocking PDE5, Viagra allows for increased levels of cyclic guanosine monophosphate (cGMP), which promotes blood flow to facilitate an erection.
Indications / Uses
Viagra is primarily prescribed for managing erectile dysfunction in men, which is characterized by the inability to achieve or maintain an erection sufficient for sexual performance. While its primary use is for ED, some studies have explored its potential in treating other conditions such as pulmonary arterial hypertension; however, this guide focuses on its most common application related to ED.
Dosage Forms and Typical Dosing Considerations
Viagra is available in oral tablet form, typically in dosages of 25 mg, 50 mg, and 100 mg. The recommended starting dose for most men is 50 mg taken approximately one hour before sexual activity. Depending on efficacy and tolerance, this dosage can be adjusted, but it should not exceed 100 mg per day. Various factors such as age, overall health, liver and kidney function, and other medications can influence dosing considerations.
How to Take It Correctly
- Follow your prescription: Always take Viagra exactly as prescribed by your healthcare provider.
- Timing: Take Viagra 30 minutes to 4 hours before engaging in sexual activity, typically around one hour is ideal.
- Food considerations: It can be taken with or without food; however, fatty meals might delay its effectiveness.
- Missed doses: Viagra is taken as needed, so the concept of a missed dose does not apply as it would with daily medications.
- Storage: Keep the tablets in their original packaging at room temperature, away from moisture and heat.
