Red flags that should end the transaction
- No prescription required. Illegal in the US, full stop.
- No licensed clinician involved — no consultation, no questionnaire reviewed by a person, no way to ask a question.
- No physical address or phone number, or an address that does not resolve to a real pharmacy.
- No pharmacist available to answer questions.
- Prices dramatically below normal generic pricing.
- Unsolicited spam email or text advertising the site.
- Foreign shipping of prescription medication into the US, which is generally unlawful for personal import.
- Payment by cryptocurrency, wire transfer or gift card only.
- Claims of a 'herbal Viagra' that works within an hour — a strong indicator of undeclared prescription ingredients.
How to verify a pharmacy in five minutes
- Check accreditation. The National Association of Boards of Pharmacy accredits legitimate digital pharmacies and publishes lists of verified and not-recommended sites.
- Check the state licence. Pharmacies must be licensed in the state they ship to. Your state board of pharmacy can confirm this.
- Confirm a clinician is involved. A named, licensed prescriber — not just an algorithm.
- Look for a real address and phone number, and try calling it.
- Check that a pharmacist is contactable for questions about interactions.
- Read the privacy policy. Health information is sensitive; find out what they collect and who they share it with.
Telehealth services vs online pharmacies
| Telehealth service | Online pharmacy | Rogue seller | |
|---|---|---|---|
| How it works | Consultation with a licensed clinician, then a prescription filled by a partner pharmacy | Fills a prescription you already have | Sells without any prescription |
| Prescription required | Yes — they arrange it | Yes — you provide it | No |
| Legal in the US | Yes | Yes, if licensed | No |
| Best for | Getting treatment without an in-person visit | Cheaper fills of an existing prescription | Nothing |
Both legitimate models are fine. The distinction that matters is whether a licensed clinician evaluates you and a licensed pharmacy dispenses to you. See our reviews of telehealth services and our telehealth vs in-person comparison.
Questions to ask any online service
- Is the prescribing clinician licensed in my state, and can I see their name?
- Which pharmacy dispenses the medication, and is it accredited?
- Can I speak to a pharmacist about interactions?
- Is this a subscription, and how do I cancel it?
- What is the total cost after any introductory offer ends?
- What happens if the dose needs changing?
- What do you do with my health data, and do you share it with advertisers?
- Will you communicate with my regular clinician if I ask?
FAQ
Frequently asked questions
Is it legal to buy ED medication online?
Yes, from a licensed US pharmacy with a valid prescription. It is not legal to buy prescription medication without a prescription, or to import it personally from abroad.
How do I know if an online pharmacy is legitimate?
Check NABP accreditation and state licensure, confirm a licensed clinician is involved, and look for a real address, phone number and contactable pharmacist.
Why are some sites so much cheaper?
Because they are not selling what they claim to be selling. Prices far below normal generic pricing are a warning, not a bargain.
Can I import cheaper medication from another country?
Personal importation of prescription drugs into the US is generally unlawful, and imported products bypass US quality controls entirely.
