Vidalista 2.5 is a lower-dose version of tadalafil, typically prescribed to individuals who may benefit from a mild dose of the medication. It is often recommended to those who experience side effects with higher doses of tadalafil or who may have less severe cases of ED. While tadalafil is also used for other medical conditions like benign prostatic hyperplasia (BPH), it is primarily known for its use in ED treatment.
