Tadapox is a medication that combines two active ingredients: tadalafil and dapoxetine. Tadalafil is used to treat erectile dysfunction (ED), while dapoxetine is used to treat premature ejaculation (PE). The duration of the effects of Tadapox can vary depending on individual factors. The effects of tadalafil, which helps improve erectile function, can last up to 36 hours. It's important to note that this doesn't mean you'll have an erection for the entire duration. Tadalafil enables the ability to achieve and maintain an erection when sexual stimulation occurs within the 36-hour timeframe. On the other hand, dapoxetine is a short-acting selective serotonin reuptake inhibitor (SSRI) that is primarily used to treat premature ejaculation. It has a shorter duration of action compared to tadalafil. Dapoxetine is rapidly absorbed and eliminated from the body, with a half-life of approximately 1-2 hours. Its effects are typically felt within 1-3 hours after ingestion. Since Tadapox contains both tadalafil and dapoxetine, the combined effects may vary. Tadalafil's effect can last significantly longer than dapoxetine's effect on premature ejaculation. It's important to follow the dosage instructions provided by your healthcare professional and to consult with them for more specific information regarding the duration of Tadapox's effects in your particular case.
