Avanafil, sold under the brand name Stendra, is a phosphodiesterase-5 (PDE5) inhibitor used to treat erectile dysfunction (ED). It works by increasing blood flow to the penis, facilitating an erection. The recommended starting dose is 100 mg, taken approximately 30 minutes before sexual activity. Dosage may be adjusted to 200 mg or reduced to 50 mg based on individual response and tolerance.
Understanding Avanafil’s Action
Avanafil’s rapid onset of action is a key differentiator. Studies show its effects can be felt within 15-30 minutes, faster than some other PDE5 inhibitors. This quick action can be particularly beneficial for spontaneity. However, it’s important to note that Avanafil’s effects last for a shorter duration, generally 4-6 hours.
Safety and Side Effects
Common side effects include headache, flushing, nasal congestion, and back pain. Serious side effects are rare but include sudden vision loss and prolonged erection (priapism). Individuals with heart conditions, low blood pressure, or those taking specific medications (like nitrates) should consult their doctor before using Avanafil. Alcohol consumption may enhance side effects.
Avanafil vs. Other ED Treatments
Compared to other PDE5 inhibitors like sildenafil (Viagra) or tadalafil (Cialis), Avanafil offers a faster onset but shorter duration of action. The choice of medication depends on individual preferences and medical history. Your doctor can help determine the most suitable treatment option for your specific needs.
Dosage and Administration
Avanafil should be taken as directed by your doctor. It’s typically administered orally with or without food. Do not exceed the prescribed dose. Consult your healthcare provider immediately if you experience any adverse reactions.
