Safety
No boxed warning. Never take it with nitrates (such as nitroglycerin or “poppers”) or riociguat: together they can cause a dangerous drop in blood pressure. Don’t combine it with another ED medicine. Get emergency care for an erection lasting more than 4 hours, and stop and call a clinician for sudden vision or hearing loss. Blood pressure can also drop with alpha-blockers, other blood pressure medicines or heavy drinking. Ask a clinician whether your heart is healthy enough for sex. Compounded products lack FDA review of quality, dose accuracy and stability.
Legal status
Prescription only; compounded and not FDA-approved. Compounded ED chewables are prepared by a compounding pharmacy for an individual prescription. Compounded products are not FDA-approved, and the FDA does not review them for safety, effectiveness or quality. A compounded chewable is not Viagra or Cialis and not a generic of either. A compounding pharmacy prepares it for an individual prescription, and it isn’t FDA-approved. On Sept 9, 2025, the FDA sent warning letters to telehealth sellers, including BlueChew, over claims that implied their compounded products matched FDA-approved ones.
What compounded ED chewables are
Compounded ED chewables contain sildenafil, tadalafil or vardenafil, one per product. Products that combine sildenafil with tadalafil, or two other ED drugs, are not covered here: the approved labels tell patients not to combine PDE5 inhibitors.
Dosing
Chewable, sublingual or dissolving tablet; some providers compound capsules, as needed, or daily for some tadalafil products. Set by your prescriber. The strength may differ from the approved tablets.
How well it works
Compounded chewables were not part of the trials behind Viagra or Cialis, and the FDA has not reviewed them for safety, effectiveness or quality. Individual results vary.
Compounded ED chewables cost
Chewables from $20 a month (BlueChew’s lowest plan) to $59 (MangoRx), or $3.53 to $4.47 a tablet at BlueChew; other compounded forms from $49.99 a month at Maximus (Oct 18, 2026).
