Potential Benefits of PT-141 (Bremelanotide)
On-Demand Option
Used “as needed” rather than daily—fits around real life and avoids continuous exposure.
Desire & Arousal Support
FDA-approved for acquired, generalized HSDD in premenopausal women; non-hormonal mechanism.
Whole-Program Friendly
Pairs with coaching on stress, sleep, meds review, and relationship context for best outcomes.
PT-141 (brand device available) is indicated for premenopausal women with acquired, generalized HSDD. Not studied/approved for men or postmenopausal women for this indication. Use only under a licensed clinician’s supervision.
Contraindications & Precautions
Contraindications
-
Uncontrolled hypertension or known cardiovascular disease

Known hypersensitivity to bremelanotide or formulation components

Use with Caution
-
Controlled hypertension—monitor; transient ↑BP/↓HR can occur for several hours

Oral meds that must work quickly—PT-141 can slow gastric emptying
-
Oral naltrexone users: exposure may be reduced; discuss alternatives

Skin hyperpigmentation risk—may cause focal darkening (face, gums, breasts); usually resolves slowly or not at all after stopping

PT-141 offers a non-hormonal, on-demand option for premenopausal women with acquired, generalized HSDD when used within a clinician-guided plan that addresses medical, psychological, and relationship factors.
Patient Story:
“Using it only when needed felt simple. Pairing it with stress and sleep coaching helped the most.” — Camila T.
Mechanism of Action
-
Melanocortin Agonist (MC4R): Acts centrally to modulate pathways tied to sexual desire and arousal
-
Non-Hormonal: Does not rely on estrogen/testosterone replacement
-
Gastric Emptying: Temporarily slows gastric emptying—may reduce exposure to certain oral meds
