Harder faster, for longer.

Circulation and desire are different problems. Quattro combines PDE5 inhibitors for blood flow with apomorphine for desire, in one sublingual dose. Your provider decides whether that combination is appropriate for you.

A 2 mL oral solution, held under the tongue rather than swallowed, which is why uptake is faster than a tablet.

You are not charged unless a provider reviews your intake and approves treatment.

Yes. Your plan renews automatically until you cancel, and you can cancel at any time.

Do not take Quattro if you take nitrates.
Nitrates include nitroglycerin, isosorbide mononitrate or dinitrate, and recreational "poppers" (amyl or butyl nitrite). Taking Quattro with a nitrate can cause a sudden, dangerous drop in blood pressure that may be fatal. Because one of Quattro’s ingredients stays in your body for a long time, do not take any nitrate for at least 48 hours after a dose. If you need emergency heart care, tell the treating clinician you have taken Quattro and when.

Do not take Quattro if you:
• take riociguat (Adempas) or another guanylate cyclase stimulator
• take ondansetron (Zofran) or another 5-HT3 antagonist — the combination can cause severe low blood pressure
• have had an allergic reaction to apomorphine, sildenafil, tadalafil or vardenafil
• are under 18, or are a woman

Talk to your provider before taking Quattro if you have heart disease or have had a heart attack, stroke or life-threatening irregular heartbeat in the last 6 months; have uncontrolled high blood pressure or low blood pressure; have chest pain during sex; take an alpha-blocker; take a medication for Parkinson’s disease, nausea or a mental health condition; have liver or kidney problems; have retinitis pigmentosa or have had sudden vision loss from NAION; have sickle cell anemia, multiple myeloma or leukemia; have a physical deformity of the penis or have had a prolonged erection before; or have a stomach ulcer or bleeding disorder.

Seek emergency care right away for an erection lasting more than 4 hours, sudden loss of vision in one or both eyes, sudden decrease or loss of hearing, or chest pain, fainting or severe dizziness.

Common side effects include headache, flushing, stuffy or runny nose, indigestion, dizziness, back or muscle aches, and changes in vision such as a blue tinge or sensitivity to light. Nausea, drowsiness and lightheadedness on standing are more common with Quattro than with a standard ED tablet because of the apomorphine component. Do not drive until you know how Quattro affects you. Alcohol makes dizziness and fainting more likely.

Quattro contains three PDE5 inhibitors in one dose. Their effects add together, so side effects may be stronger or last longer than with a single ED medication. Do not take Quattro alongside sildenafil, tadalafil, vardenafil, avanafil or any other ED treatment. Never take more than your provider prescribed. Quattro does not protect against HIV or other sexually transmitted infections.
