A nasal spray.
Not another pill.

Both. PT-141 is prescribed for women and men alike, because the pathway it acts on — the melanocortin receptors in the brain associated with desire and arousal — is the same in both. For women it is most associated with low sexual desire (HSDD, hypoactive sexual desire disorder). For men it is used to support arousal and desire, including alongside a blood-flow medication. Couples are sometimes prescribed it together.

PT-141 (bremelanotide) is a compounded peptide nasal spray that works on the central nervous system to support sexual arousal and desire. It activates melanocortin receptors in the brain associated with sexual desire, addressing libido at its neurological source.

Unlike oral medications that work by increasing blood flow, or hormonal therapies that alter hormone levels, PT-141 activates melanocortin receptors in the brain that regulate sexual desire and arousal. Use one spray per nostril 1 to 4 hours before anticipated activity. Effects can last 48 to 72 hours. Do not exceed 4 sprays in 72 hours or 8 doses in one calendar month. Individual results may vary.

Viagra (sildenafil) and Cialis (tadalafil) work by increasing blood flow — they address the physical mechanics of arousal and depend on desire already being present. PT-141 works on the brain’s desire centres, addressing wanting at the neurological level. The mechanisms are complementary, so they can be used together — but only if your provider says it is appropriate for you.

No. PT-141 is non-hormonal. It does not change or replace your hormones — it works through the brain’s natural arousal pathways, which makes it a suitable option for anyone who prefers or requires a treatment that does not involve hormone therapy.

Yes. PT-141 is a compounded medication that requires a prescription from a licensed healthcare provider. MintRx facilitates a telehealth consultation with a provider to determine your eligibility — your visit and prescription review are free.

Compounded medications are customized by a pharmacy for an individual patient and are not themselves FDA-approved; the FDA does not verify their safety, effectiveness or quality before they are marketed. However, the active pharmaceutical ingredients are sourced from FDA-registered facilities, and your prescription is filled by a licensed U.S. pharmacy.

Yes. PT-141 nasal spray is a cold-chain product — it ships overnight with a cold pack and should be refrigerated when it arrives. The beyond-use date is 35 days, so check your pharmacy label and do not use it past that date.

The most common is nausea, which is also the most frequent reason patients stop early — it typically improves after the first 2 to 3 uses, and taking your dose with food can help. Flushing and headache are also reported. Seek emergency care for signs of an allergic reaction: hives, difficulty breathing, swelling of the tongue or throat, slow heartbeat, blurred vision, numbness or hot flushes.

Same active ingredient, same mechanism. The spray is needle-free and used 1 to 4 hours before; the injection goes just under the skin, is used 4 to 6 hours before, and has to be mixed once before first use. Which is right for you comes down to preference and your provider’s guidance.
