Viagra is the original brand of sildenafil, a widely used treatment for erectile dysfunction. The same active ingredient is also available under brand names such as Vizarsin, Kamagra and Penegra, supplied as tablets in strengths ranging from 25mg to 200mg. It is a well-established standard for managing this condition.
Buying Viagra online
Generic sildenafil, often sourced from high-quality laboratories in India, offers a far more affordable alternative to the original brand. This ensures that expats and residents have consistent access to the medication they need, even when living far from a well stocked provider.
Is the Viagra on SGMeds a generic?
Yes. SGMeds ships a generic with the same active ingredient (sildenafil) at the strength you choose, not the original Viagra made by Viatris. We use the brand name so you can find the medicine, and the generic's manufacturer varies with stock.
How is Viagra priced?
Viagra comes in 25, 50, 100, 120, 130, 150 and 200mg strengths, in packs of 10 to 360 tablets. Each option's price is shown on this page in Singapore dollars, converted from US dollars, so the exchange rate can change the final amount. Larger packs work out cheaper per tablet.
