Spedra/Avanafil is a fast-acting prescription treatment for men with ED (erectile dysfunction), a condition that affects your ability to get or keep an erection. It is one of the newest drugs in the phosphodiesterase 5 type inhibitor (PDE5) family, to join the more well know ED medicines Viagra/Sildenafil and Cialis. It has been formulated to have fewer side effects and faster action and is available in 3 different strengths; 50mg, 100mg and 200mg tablets.
Spedra/Avanafil may take 15 to 30 minutes to be effective, and 30 minutes for lower-dose tablets. The effect can last for up to 4 hours but don’t worry, it will only work when you are sexually aroused.
You can take Spedra/Avanafil with or without food – but preferably not after a heavy or high-fat meal as this may delay the effect. Grapefruit juice can increase exposure to medicine and should be avoided within 24 hours before taking Spedra/Avanafil. Drinking alcohol at the same time as taking Spedra/Avanafil may increase your heart rate and lower your blood pressure. Drinking alcohol may also decrease your ability to get an erection.
How does Spedra/Avanafil work?
When you are aroused your tissues release a chemical called nitric oxide (NO), this, in turn, causes the release of a second chemical called cyclic guanosine monophosphate (cGMP). cGMP causes the muscles at the sides of your penis to relax, allowing blood to rush in. The veins that drain the blood from your penis also get compressed, trapping the increased blood in your penis, resulting in an erection. An enzyme called phosphodiesterase-5 (PDE5) breaks down the cGMP and your penis will return to its original state.
Spedra/Avanafil is a PDE5 inhibitor, meaning it blocks the action of PDE5. As your levels of cGMP remain high, the muscles at the side of your penis relax, more blood rushes in and you can achieve a firmer and longer-lasting erection. It is important to remember that Spedra/Avanafil only exerts its action when you are sexually aroused. It does not increase your sexual desire, and it will not resolve any underlying physical causes of your ED.
How long does it take Spedra/Avanafil to work?
It is one of the fastest-acting treatments for ED, taking as little as 15-30 minutes to take effect, and can last for up to four hours. The time it takes to work will be different for each man. If taken with food it can have a slower effect, so, it’s best to take it on an empty stomach or after a low-fat meal. The higher strength tablets (100mg and 200mg) should be taken approximately 15-30 minutes before you desire their effect. The lower strength tablets should be taken about 30 minutes before sexual activity. Spedra/Avanafil will only help you to get an erection when you are sexually aroused.Get Started
How do I take Spedra/Avanafil?
The recommended dose is a 100mg tablet, swallowed whole with water, as needed, but no more than once a day. You can take Spedra/avanafil with or without food, but if taken with food it may take longer to work.
If you found the effects too strong of a higher strength dose, your doctor may prescribe a lower strength dose of 50mg. If the effects are not strong enough, your doctor may prescribe the 200mg tablet. You may also need your dose adjusting if you are taking other medications. For more information please read the patient information leaflets for Spedra(avanafil).
If I take more tablets, do I get a better effect?
You must not take more than 1 tablet a day or exceed the dose recommended for you. If you feel that your dose is not appropriate, that the effects of the medication are too much, or not enough, your doctor can alter your dose.
If you do take more than the recommended dose, your risk of side effects, including serious ones, like low blood pressure or an erection that won’t go away even after 4 hours, dramatically increases. If you do experience any side effects, particularly serious side effects, you should seek medical attention immediately.Get Started
