Tablets should be swallowed whole. If taken on an empty stomach, Spedra is likely to be more active after 15 to 30 minutes and is likely to remain active for a period of 4 hours or more.
If taken on a full stomach, absorption is likely to be delayed up to 1.5 hours or more.
As with erectile dysfunction treatment, Spedra supports natural erections. Sexual arousal and normal foreplay are required for the treatment to work. Without it, the effects of a tablet simply fade for a couple of hours.
The usual starting dose is a single tablet of 100 mg, with subsequent doses adjusted according to the success of the treatment. The maximum dose is one tablet of 200 mg, the minimum dose is one tablet of 50 mg. Do not take more than 1 tablet per day.
No dose reduction is required for age, although no study information is available for men over 70 years of age.
Spedra tablets should not be taken within 24 hours of other erectile dysfunction medications.
Effectiveness of Spedra
Studies show that about 50% of men taking Spedra report success, with higher doses producing better results. In the general population with ED, the average percentage of attempts leading to successful contact was approximately 47%, 58% and 59% for the 50mg, 100mg and 200mg avanafil groups, respectively, compared to approximately 28% for placebo.
Side effects of Spedra
If men notice any of the following serious side effects, they need urgent medical treatment:
- an erection that will not disappear (priapism). If you get an erection that lasts more than 2 hours, this needs to be treated as soon as possible or permanent damage to your penis (including inability to erect) may occur.
- blurred vision.
- sudden reduction or loss of vision in one or both eyes;
- sudden decrease or loss of hearing (sometimes you may also feel dizzy or ringing in your ears);
