How does Stendra Treat Erectile Dysfunction?

What is Erectile Dysfunction?

Erectile dysfunction is a very common problem in men. It is a disorder by which you are unable to get or maintain an erection. This is also known as impotence. The common symptoms of erectile dysfunction are:

  • Unable to get an erection

  • Inability to obtain an erection that is firm enough for intercourse

Some of the most common causes of ED are:

  • Heart problems
  • High blood pressure
  • High cholesterol
  • Diabetes
  • Multiple sclerosis
  • Parkinson’s disease
  • Side effects of other drugs
  • Treatment of prostate cancer
  • Injury in the pelvic region
  • Stress
  • Depression
  • Anxiety

However, there are drugs for treating erectile dysfunction like avanafil or Stendra.


How Does The Drug Work?

The drug is known to increase the blood flow to the penis which helps in getting an erection. However, the drug does not work if you are not sexually stimulated.

Side Effects of the Drug

Some of the common side effects of the drug are:

  • Flushing
  • Dizziness
  • Headache

Usually, these side effects subside when you stop taking the medicine but if you notice that the problem persists then you should immediately consult the doctor. If you have to reduce the effect of the lightheadedness or dizziness, make sure that you get up slowly from a lying or a sitting position.

However, Canadian Health&Care Mall is of the opinion that you should just stop using the medicine, if you incur side effects like:

  • Changes in vision
  • Ringing in the ears
  • Redness of the face or chest
  • Diarrhea
  • Back pain
  • Constipation
  • Stomach upset
  • Stuffy nose
  • Sore throat
  • Sinus pain
  • Shortness of breath
  • Swelling in the hands and feet
  • Painful erection


Canadian Health&Care Mall believes that you need to maintain some precaution before taking the oral drug. You should inform the pharmacist or the doctor if you have allergies to the drug or some allergies in general. Convey your medical details to the doctor, especially if you have a history of:

  • Heart attack
  • Chest pain
  • Stroke in the last 6 months
  • Liver disease
  • Low or high blood pressure
  • Kidney disease
  • A severe loss of water from the body
  • History of prolonged and painful erection
  • Eye problems
  • Bleeding disorders

Since this drug makes you dizzy to some extent, you should avoid doing activities that need you to be alert.


DRUG INTERACTIONYou should not take this drug you are using a nitrate drug for your heart problems or chest pain. This is because taking this drug along with nitrate might lead to sudden and serious drop in the blood pressure. Riociguat is also known to react with Stendra.

Also make sure that you are not taking an alpha blocker for enlarged prostate, as this too might react with the drug to cause a drop in the blood. Contact a doctor and talk about the problem. The doctor might suggest you a lower dosage of the medicine.

There are other medications that might affect the removal of avanafil from the body. This might affect the way in which the drug works. Such medicines include:

  • HIV protease inhibitors
  • Hepatitis C virus protease inhibitors
  • Nefazodone
  • Rifampin
  • Macrolide antibiotics
  • Cobicistat
  • Azole antifungals
