liban 100 mg is a medication commonly used to treat premature ejaculation (PE) in men. Its active ingredient is dapoxetine, which belongs to a class of medications known as selective serotonin reuptake inhibitors (SSRIs). Dapoxetine works by increasing serotonin levels in the nervous system, which helps delay ejaculation and improve control during sexual activity. Fliban 100 mg is usually taken 1 to 3 hours before sexual activity. The effects can vary, but many men experience a noticeable increase in the time taken to ejaculate.
