Valif Oral Jelly 20 mg contains vardenafil, which is a medication used to treat erectile dysfunction (ED) in men. Vardenafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors, which work by increasing blood flow to the penis during sexual stimulation, allowing for an erection. Like other medications for ED, Valif Oral Jelly 20 mg should only be used under the guidance of a healthcare provider. They can assess if it's suitable for you based on your medical history and current medications.
