This guide compares the leading U.S. telehealth services that prescribe and ship erectile dysfunction (ED) treatment in 2026, medically reviewed by Dr. Marcus Tan, MD. We weigh the factors that actually matter: price per dose, whether the medication is FDA-approved or compounded, the formats offered (tablets, chewables, daily vs. as-needed), prescriber oversight, delivery speed, and how easy each service is to cancel. BestMedsHub may earn a commission from some providers listed here; that never affects our medical review or which services we include.
Most online ED providers prescribe the same two core molecules — generic sildenafil (the active ingredient in Viagra) and tadalafil (Cialis) — so the real differences come down to cost, formulation, and service quality rather than the drug itself. Because sildenafil and tadalafil are not controlled substances, a licensed clinician can prescribe them after a short online visit in all 50 states. Always review contraindications, especially nitrates and certain blood-pressure medications, with a prescriber before starting treatment.
