Tadaga 5 mg, which contains tadalafil, typically remains effective for up to 36 hours after ingestion. This long duration has earned it the nickname “the weekend pill,” as it allows for greater sexual spontaneity. However, it doesn’t cause constant erections—sexual stimulation is still needed for it to work. Onset usually begins within 30 to 60 minutes after taking the tablet. Factors such as age, metabolism, diet, and overall health can influence how long its effects last. Despite its extended window of activity, you should not take more than one dose in 24 hours. Always follow your doctor’s instructions.
