What Is Avanafil?

Avanafil belongs to the pharmacological class of PDE5 inhibitors, which makes it similar in action to such drugs as Sildenafil, Tadalafil, and Vardenafil. It is the white powder that has slight solubility in ethanol and hydrochloric acid, and is insoluble in water.

This medicament helps those men who cannot achieve firm and long erection to complete sexual intercourse. In a few words, the principle of action is as follows: the inhibitor relaxes the smooth muscles of the sponge-like body of penis and provides blood flow there, which results in an erection.

We have to mention that the phosphodiesterase type 5 enzyme can be found in various body tissues, for example in the retina and lung arteries. Thus, avanafil can influence some other processes in a human’s body. This is why it is better to consult with a doctor before using it.

Who Should Take Avanafil?

There are symptoms of ED that become a serious signal to take care of the sexual health of a man. They can come all together, or one at a time, but in both cases it is better to take steps in order to fix the problem as soon as possible. It is necessary to consult a doctor first of all, but if you notice regular signs of amorous troubles, ED medications can help quickly and effectively. Such signs can include:

  • troubles with getting erection when coitus starts along with enough sexual desire and stimulation;
  • weak erection during the intercourse;
  • lack of desire and troubles with finishing the act.

The usage of any PDE5 inhibitors must be done carefully, and there are certain precautions necessary to follow. In order to make the treatment safe and avoid bigger health damages, men with the following health conditions should take avanafil only after receiving professional medical advice:

  • high or low blood pressure;
  • chest pain;
  • recent heart operative treatment;
  • various heart disorders, like arrhythmia or heart failure;
  • recent strokes and heart attacks;
  • diseases of kidneys, stomach, liver;
  • Peyronie disease, or excessive physical deformation of phallus;
  • cancer, leukemia, hemophilia;
  • troubles with vision and hearing;
  • HIV/AIDS or hepatitis C.

Avanafil is not allowed for women and men younger than 18 years of age.

How to Use Avanafil Pills?

Take tabletThe dosage for every man is personal and should be determined according to certain factors:

  • health condition;
  • age;
  • tolerance to medicinal products;
  • severeness of the treated disorder.

The usual starting dose for an adult man is 100mg, and it is recommended to take it not less than 15 minutes before the intended coitus. If the desired effect does not occur, the dosage can be increased to 200mg 15 min before sex. Sometimes the initial dose appears to be redundant, and it can be reduced to 50mg that should be taken 30 minutes before starting intercourse.

The drug reaches its maximum concentration 30-45 minutes after administration, and its effect lasts for 6 hours. The time of the half-life plasma elimination of products based on avanafil varies from 3 to 10 hours. A man can use this medicine only once a day. There is no need to take the medication regularly, as it should only be used before sex, and remember that if you intake the pill too soon or too long before the coition, the result will fall short of the expected effect.

Side Effects

Before taking avanafil make sure that you are not allergic to any of its components. Pay attention to the response of your body to the first administration, and be careful with the dosage. Avanafil may have a list of unwanted effects, and if some of them are observed it is highly recommended to call for medical assistance.

More Common

Tell your doctor if you undergo longtime headache, back or chest pain, flushing or running nose, or sore throat. Such side effects can be moderate and cease in a short time, but if you suffer from some of them constantly and recurrently, seek for quick medical help.

Avanafil side effectsLess common undesired symptoms after usage of the ED remedies can be:

  • coughing, sneezing, sweating;
  • indigestion, diarrhea, appetite disorders;
  • fevers and chills;
  • body and joint aches;
  • anxiety, depression and troubles with sleeping;
  • itching, rash, shivering and others.

This list is not full, so you should pay attention to any unusual conditions after taking avanafil, and see if it goes away soon.


There are some indications that require immediate medical help. The following ones can be signs of severe health conditions, for example heart attack, stroke, kidney or liver failure, vision loss, and other serious troubles:

  • pain and tightness in chest, breath shortness;
  • abnormal heartbeat;
  • dizziness;
  • nausea, vomiting;

If you feel any of these, call for emergency medical assistance at once.


Back painWhen a dangerous content of the medication is introduced into the body you can feel warmth in your face, flushing, back pain, nasal stuffiness, and the common cold. If you took Avanafil more than your usual dosage or sooner than 24 hours after the last administration and feel dangerous symptoms, call the nearest emergency room.


Avanafil can interact with food, drinks, and medicines taken together with the ED medication. This interaction can change the active substance or prevent it from working properly, which can cause unwanted results. To avoid this, ask your pharmacist to direct you how to use ED medicines with other drugs.

Can I Take Avanafil with Food?

Avanafil can be taken with or without food, as usually it does not interfere with the operation of the medicine. However, some products can cause changes in the drug’s action. Food high in fat content can slow the process, reducing the absorption of the medical agent. Grapefruits and grapefruit juice increase the concentration of the inhibitors in the blood, which can cause overdose. It is better to avoid taking avanafil with them.

Avanafil and Alcohol Intake

Beverages containing alcohol taken together with avanafil can result in low blood pressure. You can feel faintness, a rush of blood to the head, and other symptoms of hypotension. Try to limit the use of spirits to three shots maximum, and the negative consequences will be nullified.

Interaction with Other Medications

As avanafil operates in the same way with all PDE5 inhibitors, it has similar precautions about using it together with other drugs.

ED medicationsAsk for medical advice if you take avanafil with:

  • analogous ED medications;
  • antimycotics;
  • antibiotics macrolides;
  • HIV therapy;
  • remedies for hepatitis С;
  • blood pressure controllers, alpha blockers and prostate diseases medicines;
  • drugs that contain nitrates;
  • barbiturates;
  • antituberculous remedies;
  • medicines that help with seizure, vomiting and nausea.

Organic nitrates together with ED treatment can lead to harmful hypotension, which can cause such severe consequences as a heart attack or stroke. Some medicines, like antibiotics, antifungals, and HIV/AIDS medications can increase the concentration of avanafil in your body to an unsafe level. On the contrary, seizure and antituberculous remedies and barbiturates decrease the level of the active ingredient of ED pills, which leads to its inefficacious work.

Avanafil Alternatives

There are many rival products on the ED medication market, all with their own advantages and disadvantages. Among the most popular are Viagra and its generics sildenafil, Cialis, Kamagra, and Levitra. They work in the same way and are analogous medications for men’s health. Tadapox stands apart as it has two active agents, tadalafil and Dapoxetine, and cures impotence together with premature ejaculation.

Avanafil Vs Viagra (Sildenafil)

To compare avanafil vs sildenafil we will consider such factors as:

  • how quickly they provide action;
  • how long does it last;
  • effectiveness;
  • and side effects.

Avanafil works much faster than Viagra, as it starts action only 15-30 minutes after intake with no dependence on food, while sildenafil needs one hour if taken with meals. Both drugs stay effective for about 6 hours and have the same side effects. In trial researches, sildenafil showed efficacious treatment for 80% of men, while avanafil gave only 60% positive results. Though, these numbers cannot be considered the final score, because there was no face-to-face testing.

Avanafil Versus Cialis (Tadalafil)

Cialis tabletsBoth tadalafil and avanafil should be taken 15 minutes before the sexual act, but Cialis works for a day and a half, while the effect of avanafil lasts only for 6 hours. They are not dependent on food; however, tadalafil is compatible with fat meals and spirits. Because of the shorter action time, avanafil seems to be less effective vs Cialis, but at the same time, the shorter time allows for fewer risks of side effects. In conclusion, we have to say that it is hard to determine the best pills for each specific man. At the moment, avanafil is one of the newest and most effectual drugs for erectile dysfunction on the market, which makes it the best seller among competitors.
