Tazzle 10 FM is a combination medication containing Tadalafil 10 mg and Fluoxetine (usually 20 mg or adjusted dose), used to address two common male sexual health issues: erectile dysfunction (ED) and premature ejaculation (PE). Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor that helps increase blood flow to the penis, facilitating erection during sexual stimulation. Fluoxetine, a selective serotonin reuptake inhibitor (SSRI), is commonly prescribed for depression and anxiety but is also effective in delaying ejaculation by modulating serotonin levels.
