Tadarise 2.5 mg is a medication containing tadalafil, which is primarily used to treat erectile dysfunction (ED) in men. Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor, similar to sildenafil (Viagra) and vardenafil (Levitra). Tadarise 2.5 mg contains a relatively low dose of tadalafil. It's typically prescribed for men who may require a lower dose of medication due to factors such as age, underlying health conditions, or sensitivity to the medication.
