Tadarise 2.5 mg is a medication that contains the active ingredient tadalafil. It is commonly used to treat erectile dysfunction (ED) and symptoms of benign prostatic hyperplasia (BPH). Tadalafil belongs to a class of medications called phosphodiesterase type 5 (PDE5) inhibitors, which work by increasing blood flow to the penis during sexual stimulation, thereby helping to achieve and maintain an erection. The dosage of Tadarise 2.5 mg (or any strength of tadalafil) should be determined by a healthcare provider based on individual factors such as the severity of ED or BPH, other medical conditions, and response to treatment. It's important to follow the prescribed dosage and instructions provided by the healthcare provider or pharmacist.
