How to pay the least

  • Ask your own clinician (a routine visit or your insurer’s telehealth line) for a generic prescription and fill it at a discount pharmacy. The drug is cheap; the markup is in the bundle.
  • Daily low-dose tadalafil costs far more per month than as-needed tablets on telehealth plans. Ask whether you need daily dosing.
  • Tablet splitting is common with generic sildenafil (one 100 mg tablet split in half gives two 50 mg doses) but only do it if your prescriber says so.
  • Compounded dissolving tablets are convenient but not FDA-approved and cost several times more than the generic tablets they contain.

Sildenafil vs tadalafil

Both are PDE5 inhibitors. Sildenafil is usually taken about an hour before sex and works for a few hours; tadalafil can work for up to 36 hours and also comes as a low daily dose. Neither may be taken with nitrate medicines (such as nitroglycerin) or riociguat. Details: MedlinePlus drug pages linked in Sources.

Do I need a prescription for sildenafil or tadalafil?

Yes, in the US both need a prescription from a licensed clinician. Telehealth services include the visit; discount pharmacies like Cost Plus Drugs need a prescription sent to them.
