Sidegra

Sidegra is a film-coated tablet containing Sildenafil Citrate as its active ingredient. It belongs to the Phosphodiesterase type 5 (PDE5) inhibitor class — the same active ingredient found in Viagra.

Sildenafil works by inhibiting the PDE5 enzyme, which increases cGMP levels in the corpus cavernosum of the penis. This causes smooth muscle relaxation and increased blood flow, resulting in an erection when sexually stimulated. The medication is not an aphrodisiac — it only works when there is sexual arousal.

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.

Take 1 tablet approximately 30–60 minutes before sexual activity. Swallow whole with water. Do not take more than 1 tablet in 24 hours.

Choosing the right strength:

Sidegra 50 mg — Recommended starting dose for first-time Sildenafil users. Allows you to assess how your body responds before considering a higher dose.

Sidegra 100 mg — For men who have used Sildenafil before and found 50 mg insufficient. Do not increase your dose without consulting a pharmacist.

Food interaction: Best taken on an empty stomach for fastest absorption. High-fat meals may delay onset and reduce effectiveness.

Common side effects (usually mild and resolve within a few hours):

• Headache — the most common
• Flushing
• Dyspepsia (indigestion)
• Nasal congestion
• Dizziness

Rare but serious side effects (stop taking the medication and seek medical attention immediately):

• Chest pain
• Sudden changes in vision or blue-tinted vision
• Sudden decrease in hearing
• Erection lasting more than 4 hours (priapism) — this is a medical emergency

In clinical studies in Thai men, the most common side effects were flushing (14.3%), headache (6.3%), and dizziness (6.3%), all of which were mild in nature.

Do not use:

• If allergic to Sildenafil or any ingredients in the tablet
• If taking nitrate medications (e.g., Nitroglycerin, Isosorbide) — can cause a life-threatening drop in blood pressure
• If you have severe cardiovascular conditions where sexual activity is medically inadvisable
• If you have a history of heart attack or stroke
• If you have low blood pressure (below 90/50 mmHg)
• If under 18 years of age

Use with caution:

• If you have liver or kidney disease — may need to start with a lower dose
• Avoid excessive alcohol — may reduce effectiveness and increase side effects

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.
