Tadacip 20 mg contains tadalafil, a medication commonly prescribed for erectile dysfunction. The maximum recommended dose of Tadacip is 20 mg within a 24-hour period. Taking more than one Tadacip 20 mg tablet in a single day is not advised because tadalafil has a relatively long half-life of about 17–36 hours, meaning it remains active in the body for an extended period. Exceeding the maximum dose can increase the risk of side effects such as headache, dizziness, low blood pressure, nasal congestion, back pain, or prolonged and painful erections (priapism). Some individuals may be prescribed lower doses, such as 5 mg or 10 mg, depending on their health status and treatment goals. For daily use, doctors often recommend 2.5 mg or 5 mg once daily instead of 20 mg. Patients should never increase the dosage on their own; a healthcare provider should guide adjustments based on response and tolerability.
