Sildenafil, commonly known as generic Viagra, is the unbranded version of the medication. It offers a more cost-effective alternative to branded Viagra while maintaining the same effectiveness in treating erectile dysfunction. Both Viagra and generic Viagra contain sildenafil citrate as their active ingredient.

Sildenafil is a medication designed for on-demand use when you anticipate sexual activity. Here are some useful guidelines:

1. Test it individually first: Before engaging with a partner, try the medication alone to understand its effects on your body.

2. Take it at least 60 minutes before sexual activity: Sildenafil typically remains effective in the body for approximately 4-6 hours.

3. Optimal effectiveness on an almost empty stomach: For best results, avoid consuming fatty foods and alcohol before using the treatment.

4. Arousal is essential: Sildenafil does not induce an erection automatically. Engage in foreplay to enhance its efficacy and achieve the desired results.

The following safety information is crucial to consider before taking sildenafil:

1. **Avoid Nitrate Medications:** Do not take sildenafil if you are currently using any medications containing nitrates, commonly prescribed for chest pain, or guanylate cyclase stimulators like Adempas (riociguat). Combining these drugs with sildenafil can cause a sudden and potentially dangerous drop in blood pressure.

2. **Inform Your Healthcare Provider:** Make sure to inform your healthcare provider about all medications you are currently taking, including prescription, over-the-counter medicines, vitamins, and herbal supplements, before starting sildenafil treatment.

3. **Potential Side Effects:** Be aware of the possible side effects of sildenafil, which may include stuffy or runny nose, flushing, headaches, heartburn, dizziness, muscle aches, and nausea. If you experience any severe or persistent side effects, seek medical attention promptly.

4. **Medical History:** Disclose your complete medical history to your healthcare provider, especially if you have a history of cardiovascular issues, low or high blood pressure, liver or kidney problems, bleeding disorders, or any other medical conditions that may affect your suitability for sildenafil treatment.

5. **Follow Prescribed Dosage:** Take sildenafil exactly as prescribed by your healthcare provider. Do not exceed the recommended dosage or take it more frequently than instructed.

6. **Emergency Situations:** In case of a medical emergency, such as a prolonged or painful erection lasting more than four hours, seek immediate medical assistance.
