Viagra (sildenafil) helps achieve and maintain an erection by increasing blood flow to the penis. This happens because it blocks an enzyme called phosphodiesterase-5 (PDE5), allowing nitric oxide to work more effectively.
Here’s what you can expect:
- Onset of action: Viagra typically takes 30-60 minutes to work, but this can vary depending on individual factors and food intake. Duration of effect: The effects usually last for 4-5 hours, allowing for multiple attempts at sexual intercourse. Dosage: Your doctor will prescribe the right dose for you, usually starting with 50mg. Never adjust your dosage without consulting your physician. Side effects: Common side effects include headache, flushing, nasal congestion, and upset stomach. These are usually mild and temporary. More serious side effects are rare but require immediate medical attention.
Before taking Viagra:
Consult your doctor: Discuss your medical history, including any heart conditions, high blood pressure, or other medications you’re taking. Avoid alcohol: Excessive alcohol can interfere with Viagra’s effectiveness and increase the risk of side effects. Avoid grapefruit juice: Grapefruit juice can interact with Viagra and lead to increased side effects. Expect variations: Individual responses to Viagra vary. What works for one person may not work exactly the same for another. Open communication with your physician is key.
Remember: Viagra is a prescription medication and should only be used as directed by your doctor. If you experience any concerning side effects, contact your doctor immediately.
