Caverta 100 mg is a medication that contains sildenafil citrate as its active ingredient. Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, which helps men achieve and maintain an erection when sexually stimulated. Caverta 100 mg, like other sildenafil-based medications, is intended to help men with ED improve their ability to achieve and sustain an erection. The standard dose is 100 mg, but the dosage may be adjusted based on individual response and tolerability.
