We line up generic sildenafil, tadalafil, vardenafil, and avanafil by active ingredient, strength, and per-unit price — so you can compare listings before deciding whether a route is appropriate and lawful where you live.
Catalog pricing captured from the source; verify the current checkout price and requirements.
Full disclosure
Regulatory status stated plainly — see below.
The Comparison
Six formulations, one table.
Every generic ED formulation carried in the catalog, grouped by active ingredient. Strength ranges below reflect commonly available dosing for each compound — confirm exact options on the product page.
This is an ingredient comparison, not a live price catalog. Current provider links are disclosed separately. Verify the full price and medical eligibility with the provider.
Some historical international combination products are not FDA-approved in the United States. These rows are ingredient education, not a recommendation to buy them or a list of available prescriptions.
Prescription guide
Start with the ingredient, not a catalog brand.
Sildenafil and tadalafil are prescription medicines. Compare formulation, screening, dispensing pharmacy, total cost, and refill policy before choosing a treatment service. Old international catalog pricing has been retired because it cannot be verified.
In the United States, the FDA requires a generic medication to contain the same active ingredient, strength, dosage form, and route of administration as its brand-name counterpart, and to demonstrate bioequivalence before it can be approved. The brand name is largely the packaging, marketing, and patent premium built on top of the same compound.
That's the economic logic behind every drug on this page: sildenafil is sildenafil, whether the box says Viagra® or a generic manufacturer's name.
Historical catalog note
HealthyRXS was previously referenced in our international catalog coverage. That affiliate is on hold, and its prices, fulfillment, and promotional eligibility are not currently verified. This website now prioritizes prescription-based care comparisons with clear pharmacy sourcing.

Nitrate warning: Sildenafil, tadalafil, vardenafil, and avanafil can cause a dangerous drop in blood pressure when combined with nitrate medications (often prescribed for chest pain or heart disease). If you take nitrates, have cardiovascular disease, or are unsure whether these medications are safe for you, talk to a doctor or pharmacist before ordering — with no prescriber screening involved in this purchase path, that check is on you.
Paid comparisons / U.S. prescription-care routes
Compare the clinician-reviewed route
These are tracked provider links, not medical endorsements or personalized rankings. Compare the prescribing process, licensed pharmacy, total price, and support before choosing. Sildenafil and tadalafil are prescription medicines, and they are not safe with nitrates. Providers must determine eligibility.

What's actually different between generic and brand-name ED medication?
The active ingredient and mechanism are the same — sildenafil is sildenafil. What differs is the manufacturer, the packaging, the price, and in this case, the regulatory pathway the product came through (see the disclosure above). Some people also notice differences in inactive ingredients, tablet coating, or manufacturing consistency between generic sources.
Is it legal to order generic ED medication from an international pharmacy?
Laws vary by country and even by state or province. Importing prescription-equivalent medication for personal use is a legal gray area in many jurisdictions rather than a clear yes or no. We're not able to give legal advice on your specific situation — if you're unsure, check your local regulations before ordering.
How does international shipping and customs work?
For a prescription medicine, use a licensed prescriber and verify the pharmacy in the relevant jurisdiction. Do not rely on historical catalog or import guidance as assurance of safety, legality, shipping, or refunds. Check current terms with the licensed provider.
How do I know which strength is right for me?
For a prescription medicine, use a licensed prescriber and verify the pharmacy in the relevant jurisdiction. Do not rely on historical catalog or import guidance as assurance of safety, legality, shipping, or refunds. Check current terms with the licensed provider.
Can I take these with other medications I'm on?
Possibly not safely — nitrates are the best-known interaction (see the warning above), but alpha-blockers, certain blood pressure medications, and some other prescriptions can also interact with PDE5 inhibitors like sildenafil and tadalafil. Talk to a doctor or pharmacist about your specific medication list before ordering.
What if my order doesn't arrive, or arrives damaged?
For a prescription medicine, use a licensed prescriber and verify the pharmacy in the relevant jurisdiction. Do not rely on historical catalog or import guidance as assurance of safety, legality, shipping, or refunds. Check current terms with the licensed provider.
