Compare active ingredients, manufacturer, price, and brand-name premiums.
Same active ingredient, different product
Viagra contains sildenafil and Cialis contains tadalafil. FDA-approved generics contain the same active ingredient and must meet regulatory standards, but inactive ingredients and manufacturer differ.
Brand premiums can be substantial
Compare the exact dose and quantity. Brand pricing can be many times the generic price.
Avoid counterfeit marketplaces
Use a licensed prescriber and pharmacy. Do not buy prescription ED drugs from unverified social-media sellers or “no prescription” websites.
