For most healthy men, Vidalista 20 mg is considered safe, and it provides effective relief for ED. It works by inhibiting the PDE5 enzyme, which relaxes the blood vessels in the penis, allowing for improved blood flow and making it easier to achieve and maintain an erection. Typically, it’s taken 30 to 60 minutes before sexual activity and can last up to 36 hours. Generally, Vidalista 20 mg can be taken safely by most men who are prescribed the medication by a doctor. However, its safety depends on several factors, including individual health conditions, the presence of other medications, and the correct use of the drug.
