Vidalista 40 contains 40 mg of tadalafil, a medication used to treat erectile dysfunction (ED) by increasing blood flow to the penis. Vidalista 40 mg is a relatively high dose, and for most men starting ED treatment, beginning with a lower dose is generally recommended. The typical starting dose is Vidalista 10 mg or 20 mg, taken 30 to 60 minutes before sexual activity. Starting with a lower dose allows your doctor to evaluate how your body responds to the medication and minimize the risk of side effects such as headache, dizziness, indigestion, or back pain. Vidalista 40 may be considered for those who do not experience sufficient results with lower doses. However, it is essential to consult a healthcare provider before starting Vidalista or adjusting the dose to ensure safety and effectiveness.
