Da Zeagra Tablet contains Dapoxetine 30 mg and Sildenafil 50 mg, which are used to manage premature ejaculation and erectile dysfunction, respectively. You should not take 2 tablets at once unless specifically prescribed by a doctor, as doubling the dose can increase the risk of side effects such as headache, dizziness, low blood pressure, or heart-related issues. If the usual dose does not give the desired effect, consult your doctor to determine the safe and appropriate dose.
