Sidegra

Erectile Dysfunction (ED)
Taken as needed before sexual activity. Ideal for men who want immediate effect when they need it. In clinical studies conducted in Thai men, Sildenafil helped achieve successful intercourse in approximately 66% of attempts, compared to 33% with placebo. See other options in our erectile dysfunction treatment collection.

Sidegra vs. Viagra: Same active ingredient (Sildenafil), identical mechanism of action. Sidegra is a Thai-manufactured generic — equivalent quality at a more accessible price.

Sildenafil (Sidegra) vs. Tadalafil:

Sildenafil (Sidegra) — Fast-acting, works within 30–60 minutes. Lasts 4–6 hours. Taken as needed. High-fat meals may reduce absorption. Best for men who want immediate effect and can plan ahead.

Tadalafil (Talafil, Cialis) — Effective for up to 36 hours. Can be taken daily or as-needed. Food has no effect. Also treats BPH. Best for men who want spontaneity without timing.

For Sildenafil in other forms, consider Kamagra Oral Jelly (gel form, faster absorption). See all options in our Sildenafil collection.

Strictly contraindicated:

• Nitrates (see "Contraindications" section above for details)
• Other PDE5 inhibitors — do not use Sildenafil together with Tadalafil or Vardenafil

Use with caution:

• Alpha-blockers such as Doxazosin (Cardura XL, Cazosin) — may enhance blood pressure–lowering effects, space out dosing
• HIV protease inhibitors such as Ritonavir — may increase Sildenafil levels, dose adjustment needed
• Erythromycin, Ketoconazole — CYP3A4 inhibitors that may increase Sildenafil levels

Always inform your doctor or pharmacist about all medications you are currently taking before starting Sidegra.

Sildenafil has a half-life of approximately 4 hours. It begins working within 30–60 minutes and reaches peak blood levels in about 1 hour. The total duration of effectiveness is approximately 4–6 hours, though some men may experience effects for up to 8 hours.

Factors that influence duration include food intake (high-fat meals delay absorption), age, overall health, and severity of ED.

Sidegra and Viagra contain the same active ingredient, Sildenafil, and work in exactly the same way. Sidegra is a Thai-manufactured generic, certified by the Thai FDA. Same quality, more accessible price.

Take Sidegra approximately 30–60 minutes before sexual activity. It works fastest on an empty stomach. High-fat meals may delay its onset.

Approximately 4–6 hours. It reaches peak blood levels within about 1 hour. Some men may experience effects for up to 8 hours, depending on individual factors.

Start with 50 mg to assess how your body responds. If 50 mg is not sufficient, your pharmacist may recommend increasing to 100 mg. Never increase the dose on your own.

Best to limit or avoid alcohol. It can reduce the effectiveness of Sildenafil and increase the risk of dizziness, headache, and low blood pressure.

No. Sildenafil does not cause physical dependence. You can stop using it at any time without withdrawal symptoms. It only works when you take it as needed.
