Buy STENDRA (avanafil) Online: What You Need to Know
STENDRA (avanafil) is a prescription medication used to treat erectile dysfunction (ED).
ED occurs when someone has difficulty getting or keeping an erection. STENDRA helps by improving the natural chemical signals released during sexual stimulation. It relaxes the blood vessel muscles in the penis, increasing blood flow and leading to an erection.
How to Take STENDRA
The typical starting dose is 100 mg, taken orally about 30 minutes before sexual activity. It should not be used more than once per day. Depending on how well it works and any side effects, the dose can be adjusted between 50 mg and 200 mg.
If you are taking medications that interact with STENDRA, such as CYP3A4 inhibitors or alpha-blockers, the starting dose is reduced to 50 mg.
