Generic Viagra: What to Know
Generic Viagra is sildenafil — the same active ingredient as brand-name Viagra when dispensed appropriately. A clinician and pharmacy determine what you receive. Generic does not mean unregulated; FDA-approved generics meet the same active-ingredient standards.

Brand vs generic
Viagra is a brand name. Sildenafil is the generic name for the active ingredient. When a clinician prescribes sildenafil, your pharmacy may dispense a generic version if one is available and appropriate.
Inactive ingredients (fillers, coatings) can differ between brands and generics. Most men tolerate generics well, but tell your clinician if you notice a change in response or side effects after a switch.
How prescriptions work
A licensed clinician evaluates your health history before prescribing sildenafil — whether brand or generic. Online care can be appropriate when remote evaluation is safe. The prescription itself does not guarantee a specific brand at the pharmacy.
This is not a shopping guide. Treatment decisions require clinical evaluation.
Safety and counterfeit risk
Only use sildenafil obtained through a licensed pharmacy with a valid prescription. Counterfeit pills sold online without proper oversight can contain wrong doses or harmful ingredients.
If a price seems too good to be true or no clinician is involved, that is a red flag — not a bargain.
