Vidalista 2.5 mg is a low-dose, extended-release medication used to treat erectile dysfunction (ED) in men. Unlike standard tadalafil tablets, this extended-release (ER) formulation is designed to maintain stable levels of the drug in the bloodstream over a longer period, providing continuous erectile support. Common side effects are generally mild and may include headache, flushing, nasal congestion, muscle aches, and mild stomach upset. Rare serious effects, such as prolonged erections or cardiovascular complications, require immediate medical attention.
