What is Spedra?
Spedra, also known by its generic name avanafil, is a newer medication for treating ED.
It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors, which also includes Viagra.
Spedra works by increasing blood flow to the penis, helping to achieve and maintain an erection.
What is Viagra?
Viagra, with the generic name sildenafil, is one of the most well-known treatments for ED. The FDA first approved it as an oral PDE5 inhibitor for use.
It has been helping men with ED for over two decades.
Like Spedra, Viagra increases blood flow to the penis to help achieve and maintain an erection.
Key Differences Between Spedra vs Viagra
- Onset of Action: One of the most significant differences between Spedra and Viagra is how quickly they start to work.
Spedra can begin to take effect in as little as 15 minutes.
It is one of the fastest-acting ED medications available. Viagra typically takes about 30 to 60 minutes to start working. - Duration of Effect: Both medications are effective for several hours, Viagra and Spedra’s effects can last up to 6 hours.
- Food Interactions: Viagra’s effectiveness can be reduced if taken with a high-fat meal, which can delay its absorption. Spedra is less affected by food.
It is best to follow your doctor’s advice on how to take your medication. - Side Effects: Both Spedra and Viagra have similar side effects, including headaches, flushing, nasal congestion, and dizziness. However, individual responses can vary, and some men may tolerate one medication better than the other. Fewer side effects can be expected with Spedra compared to Viagra. this is because Spedra is designed to be a more selective medication compared to Viagra.
Usage and Administration
Always follow your doctor’s instructions on how to take these medications to ensure optimal results and minimize side effects.
Who Should Not Take These Medications?
Men taking nitrates for chest pain or heart problems should not take Spedra or Viagra.
