Learn about Sidegra, a more affordable Thai alternative to Viagra.
What is Sidegra?
- Sidegra is Thailand's version of Viagra — it contains the same active ingredient, Sildenafil
- It improves blood flow to the penis, making it easier to get and maintain an erection when aroused
- Effects last approximately 4–6 hours; take 30–60 minutes before activity, works best on an empty stomach
- Available in 2 strengths — start with the lower dose and adjust as needed
- Made in Thailand by GPO; more affordable than Viagra
- Do not use with nitrate medications, and do not take more than once per day
What is Sidegra?
Sidegra is a pharmacist-dispensed medicine that helps treat erectile dysfunction (ED). It is manufactured in Thailand by the Government Pharmaceutical Organization (GPO) and contains Sildenafil Citrate — the same active ingredient found in Viagra.
Simply put, Sidegra is Thailand's version of Viagra, offering comparable effectiveness at a much more accessible price point, since it is a generic medicine that does not carry the research and branding costs of Viagra.
Sidegra is not only for men experiencing severe ED — it is also suitable for men who want added confidence in the bedroom, whether for a special occasion or simply as part of taking better care of themselves.
How Does Sidegra Work? (Sildenafil Mechanism)
Sildenafil belongs to a class of medicines called PDE5 inhibitors. It works by blocking the PDE5 enzyme, which normally causes blood vessels in the penis to constrict. When this enzyme is inhibited, the blood vessels relax and dilate, allowing greater blood flow, which makes it easier to achieve and maintain an erection.
Key things to know:
- Sidegra does not cause an automatic erection — sexual arousal or stimulation is still required for the medicine to take effect
- It helps "open the pathway" for better blood flow; it is not a libido-enhancing drug
- Effects last approximately 4–6 hours after taking it — this does not mean a constant erection, but rather an enhanced ability to achieve one during that window

Sidegra vs Viagra — What's the Difference?
A common question — the short answer is the active ingredient is exactly the same (Sildenafil Citrate). The differences come down to:
| Sidegra | Viagra | |
|---|---|---|
| Made in | Thailand (GPO) | Overseas (Pfizer) |
| Type | Generic medicine | Original brand-name |
| Price | Better value | Higher |
| Effectiveness | Comparable | Comparable |
In terms of effectiveness, both work the same way — the choice comes down to budget and personal preference.

Who Is Sidegra For?

Frequently Asked Questions
