Introduction
Erectile dysfunction (ED) affects millions of men worldwide. It can harm quality of life and strain relationships. Modern drugs have changed how we treat ED. Avanafil is one of the newer options available. This guide explains what Avanafil is, how it works, its benefits, and its risks.
What is Avanafil?
Avanafil (sold as Stendra® in the US and Spedra® in Europe) treats erectile dysfunction. It belongs to a class of drugs called PDE5 inhibitors. The FDA approved it in 2012, making it one of the newer ED medications.
“Avanafil is an important step forward in ED treatment options,” says Dr. Jonathan Mercer, a urologist who specializes in men’s sexual health. “As a second-generation medication, it was designed to fix some problems with earlier ED drugs.”
How Avanafil Works
To understand how Avanafil works, you need to know how erections happen. During sexual arousal, your body releases nitric oxide in the penis. This triggers an enzyme that increases levels of a chemical called cGMP. This chemical relaxes smooth muscles and increases blood flow, causing an erection.
Avanafil works by:
- Blocking the enzyme that breaks down cGMP
- Allowing cGMP to last longer in the body
- Keeping blood vessels dilated
- Improving blood flow to the penis during sexual arousal
“What makes Avanafil special is how precisely it targets the PDE5 enzyme,” explains Dr. Sarah Chen, clinical pharmacologist. “This precision may lead to fewer side effects compared to older medications.”
Remember that Avanafil doesn’t cause automatic erections. You still need sexual stimulation for it to work. The drug enhances your natural response rather than creating an artificial one.
Quick Action and Other Benefits
One of Avanafil’s biggest advantages is how quickly it works. Some men see results in as little as 15 minutes. The label suggests taking it about 30 minutes before sex.
“The quick action of Avanafil allows for more spontaneity, which many couples value highly,” says Dr. Richard Thomas, sexual health specialist. “This fixes one of the main complaints about earlier ED treatments—the need for too much planning.”
Avanafil typically works for 4-6 hours. This provides enough time for most users without lasting unnecessarily long.
How Well It Works
Avanafil comes in three strengths: 50 mg, 100 mg, and 200 mg. Doctors usually start patients at 100 mg and adjust based on results and side effects.
Clinical studies show strong results:
- With 100 mg: about 57% of sexual attempts succeeded
- With 200 mg: about 57-63% of sexual attempts succeeded
“What’s impressive is how Avanafil helps different types of patients,” notes Dr. Michael Williams, director of a men’s health clinic. “Studies show benefits even in hard-to-treat groups, including men with diabetes and those who’ve had prostate surgery.”
Side Effects and Safety
Avanafil has fewer side effects than some older ED drugs. The most common side effects include:
- Headache (5-10% of patients)
- Flushing (3-6%)
- Nasal congestion (1-3%)
- Back pain (1-3%)
- Dizziness (1-2%)
“Most side effects from Avanafil are mild and don’t last long,” explains Dr. Elizabeth Norton, medication safety expert. “Most men find these effects manageable and keep taking the medication.”
Who Shouldn’t Take Avanafil
Avanafil isn’t safe for everyone. Don’t take it if you:
- Take nitrates for chest pain/angina
- Use “poppers” (amyl nitrite, butyl nitrite)
- Have severe heart disease
- Have severe liver problems
- Have end-stage kidney disease
Drug Interactions
Avanafil can interact with other medications:
- Nitrates: Can cause dangerous blood pressure drops; never combine these
- Alpha-blockers: May lower blood pressure too much; use with caution
- Other ED medications: Don’t take together
- Certain antibiotics, antifungals, and HIV drugs: May increase Avanafil in your body
“Always tell your doctor about all medicines you take,” stresses Dr. Robert Chen, clinical pharmacist. “This includes over-the-counter products and supplements.”
Advantages of Avanafil
Avanafil offers several benefits:
- Works quickly (as fast as 15 minutes for some men)
- Targets the right enzymes more precisely
- Works for many different types of patients
- Food doesn’t affect it as much as some other ED drugs
- Works well for “as-needed” use
Limitations
Potential drawbacks include:
- Costs more than generic versions of older ED drugs
- Not suitable for daily use
- Has less long-term safety data than older medications
- Doesn’t work for all men with ED
- Can’t be taken with nitrate medications
Special Patient Groups
Avanafil works differently in certain groups:
Older Men Older men usually don’t need a different dose. However, doctors may start with a lower dose due to age-related changes in how the body processes drugs.
Men with Diabetes Studies show Avanafil helps men with diabetes, though it may not work as well as in men without diabetes. Up to 75% of men with diabetes experience ED.
After Prostate Surgery Avanafil can help some men who’ve had prostate surgery. Success rates are typically lower in this group. Starting treatment early and using it consistently may improve results.
Comparing ED Treatments
How Avanafil compares to other ED medications:
- Sildenafil (Viagra®): Avanafil works faster but doesn’t last as long
- Tadalafil (Cialis®): Avanafil doesn’t last as long (4-6 hours vs. up to 36 hours) but may cause fewer muscle aches
- Vardenafil (Levitra®): Similar duration but Avanafil usually works faster
“Each ED drug has unique features that may benefit different men,” explains Dr. James Peterson, urologist. “Some men prefer the longer-lasting effect of tadalafil, while others value how quickly Avanafil works. Treatment should be personalized.”
Other Treatment Options
Avanafil is just one way to treat ED:
- Vacuum pumps
- Penile implants
- Injections into the penis
- Lifestyle changes (exercise, weight loss, quitting smoking)
- Sex therapy
“Medication is just one approach to ED,” emphasizes Dr. Rachel Henderson, sex therapist. “A complete treatment plan often addresses psychological factors, relationship issues, and lifestyle habits that contribute to ED.”
Using Avanafil Effectively
To get the best results:
- Take Avanafil about 30 minutes before sex
- Remember that sexual stimulation is necessary
- Avoid heavy, fatty meals before taking Avanafil
- Limit alcohol, as it may increase side effects
- Take no more than one dose per day
Cost and Insurance
As a brand-name drug, Avanafil usually costs more than generic versions of older ED medications. Insurance coverage varies widely.
“Cost remains a major barrier for many men seeking ED treatment,” notes Dr. Anthony Garcia, health policy researcher. “With few generic options for newer drugs like Avanafil, out-of-pocket costs can be high.”
Men should explore:
- Insurance coverage
- Manufacturer discount programs
- Prescription savings cards
- Comparing prices at different pharmacies
Beyond the Physical Aspects
Effective ED treatment isn’t just about the physical side of the problem.
“ED rarely exists in isolation from psychological and relationship factors,” explains Dr. Claire Johnson, sex therapist. “Even with effective medication, it’s important to address performance anxiety, communication issues, and sexual expectations.”
Research shows that combining ED drugs with therapy may work better than medication alone, especially when psychological factors play a role.
Partner Involvement
Including your partner in treatment discussions can:
- Improve communication about sexual needs
- Reduce pressure around sexual performance
- Create realistic expectations about the medication
- Lead to greater satisfaction with treatment
Frequently Asked Questions

What’s the difference between Avanafil and Viagra? Both treat erectile dysfunction, but they differ in several ways:
- Speed: Avanafil works faster (15-30 minutes vs. 30-60 minutes)
- Targeting: Avanafil targets the right enzymes more precisely
- Food effects: Food affects Avanafil less than Viagra
- Cost: Viagra is available as a cheaper generic, while Avanafil is brand-name only in most places
Is Avanafil covered by insurance? Coverage varies by insurance provider and plan. As a brand-name medication without generic versions, Avanafil may have limited coverage or higher copays compared to generic ED medications. Check with your insurance provider.
Can I use Avanafil if I have heart problems? It depends on your specific heart condition. Avanafil isn’t safe for men taking nitrates or those with unstable angina, recent heart attack, severe heart failure, or uncontrolled high blood pressure. Men with heart disease should get a cardiac evaluation before starting any ED medication.
What should I do if Avanafil doesn’t work for me? If Avanafil doesn’t give satisfactory results after several attempts (usually 4-8 tries), talk to your doctor. Options might include:
- Adjusting your dose
