Poxet 90 mg, containing dapoxetine, is primarily used to treat premature ejaculation in men. While many users experience only mild side effects like nausea, dizziness, or headache, some serious side effects require immediate medical attention. Poxet 90mg include fainting, irregular heartbeat, blurred vision, chest pain, mood changes (such as anxiety or depression), and signs of serotonin syndrome like agitation, hallucinations, rapid heartbeat, and muscle stiffness. Rarely, seizures may also occur. Additionally, if the user has a history of heart problems, Poxet may increase cardiovascular risks. Due to these potential complications, it's crucial to use the medication under a doctor's supervision.
