Priligy - Comprehensive Usage Guide: instructions, indications, composition, side effects
Composition
- Active Ingredient: Dapoxetine hydrochloride
- Excipients: May include lactose monohydrate, microcrystalline cellulose, croscarmellose sodium, colloidal anhydrous silica, magnesium stearate, hypromellose, titanium dioxide (E171), lactose monohydrate, triacetin, iron oxide black (E172), iron oxide yellow (E172), and other inactive ingredients depending on the formulation.

Pharmacological Group
Priligy belongs to the pharmacological group of selective serotonin reuptake inhibitors (SSRIs) used for the treatment of premature ejaculation (PE) (ATC code: N06AX23).
Pharmacological Properties
- Pharmacodynamics: Dapoxetine selectively inhibits the reuptake of serotonin, thereby prolonging the time to ejaculation and improving control over ejaculation.
- Pharmacokinetics: After oral administration, dapoxetine is rapidly absorbed, with peak plasma concentrations achieved within 1 to 2 hours. It undergoes extensive hepatic metabolism and is excreted primarily in urine.
Indications
Priligy is indicated for the treatment of premature ejaculation in adult men aged 18 to 64 years.
Contraindications
Priligy is contraindicated in individuals with:
- Hypersensitivity to dapoxetine or any component of the formulation
- Concurrent use with monoamine oxidase inhibitors (MAOIs) or within 14 days of discontinuing MAOI therapy
- Significant cardiovascular conditions (e.g., heart failure, conduction abnormalities)
Interactions
Dapoxetine may interact with various medications, including:
- MAOIs
- Serotonergic drugs (e.g., SSRIs, tricyclic antidepressants)
- Drugs metabolized by the CYP3A4 enzyme system (e.g., ketoconazole, erythromycin)
- Drugs that increase serotonin levels (e.g., triptans, tramadol)
Specifics of Use
- Priligy tablets should be taken orally as needed approximately 1 to 3 hours before anticipated sexual activity, with a full glass of water, with or without food.
- The recommended starting dose is 30 mg, with adjustments made based on individual response and tolerability, up to a maximum dose of 60 mg.
- Priligy is not intended for continuous daily use and should not be taken more than once every 24 hours.
