FROM OUR PHYSICIANS
“Premature ejaculation gets joked about far more often than it gets treated, and that silence keeps men out of real medical conversations. We prescribe paroxetine off-label for this, at a carefully considered dose, with a physician reviewing your history first. This condition deserves that level of seriousness.”

Simal Patel, MD
Founder and CEO at Strut Health
ParoxetineRx is a physician-prescribed compounded capsule combining Paroxetine, an SSRI used off-label for premature ejaculation, with trusted ED ingredients in a single as-needed dose.
PAROXETINERX pairs Paroxetine 20mg with Tadalafil 20mg. PLUS steps the Paroxetine up to 40mg with the same Tadalafil 20mg. MAX 2.0 adds Sildenafil and Apomorphine alongside Paroxetine 20mg and Tadalafil 7.5mg, and MAX 2.0 DOUBLE is that same combination at double the strength, for PE and ED support in one capsule.
Both are SSRIs that delay ejaculation by affecting serotonin. Paroxetine is an established, widely prescribed SSRI used off-label for PE; Dapoxetine is a shorter-acting SSRI developed specifically for on-demand PE dosing but is not FDA-approved in the U.S. Your physician can help determine which approach fits your history.
Both may meaningfully delay ejaculation, and response varies by individual. Paroxetine has decades of clinical use as an SSRI, though primarily studied for mood disorders rather than PE specifically. Your prescribing physician can help set expectations based on your history.*
Take ParoxetineRx as directed by your doctor, typically as-needed, before anticipated sexual activity. Follow your physician's specific dosing instructions.
Most patients experience effects within 1 to 3 hours of taking their dose. The Tadalafil component remains active for up to 36 hours.
No. ParoxetineRx is designed for as-needed dosing, with no daily commitment required. Follow your prescribing physician's instructions.
Common side effects include nausea, drowsiness, dizziness, dry mouth, sweating, headache, and gastrointestinal upset.
Share any history of mood disorders, bleeding disorders, heart problems, low blood pressure, vision or hearing concerns, and any antidepressants, MAOIs, or other current medications.
Avoid MAOIs, other SSRIs, nitrate drugs for chest pain, and grapefruit products. Limit alcohol use, which may increase dizziness and side effects.
Taking more than your prescribed dose can increase side effects, including serotonin syndrome symptoms or a painful, prolonged erection. Contact your doctor or seek emergency care if this occurs.
Store ParoxetineRx in a cool, dry place, away from direct light and out of reach of children. Follow any additional instructions provided with your prescription.
We work with leading physicians and compounding pharmacists with decades of experience in sexual health and performance medicine.
