Caverta 100 mg is a medication used to treat erectile dysfunction (ED) in men. It contains sildenafil citrate, a PDE5 inhibitor that improves blood flow to the penis, helping men achieve and maintain an erection during sexual stimulation. Caverta 100 mg may help improve erectile function when used appropriately. However, the highest dose is not necessarily the best choice for everyone. Consult a healthcare professional to determine a safe, effective dose for your circumstances.
