About the Erectile Dysfunction Sample Pack

There are many different types of pills for erectile dysfunction (ED). The pills work in different ways and have different instructions for use. This sample pack allows you to try out which ED pill you like best.

The pack contains tablets of the five most widely used and prescribed ED medicines:

  • Viagra (active substance: sildenafil).
  • Cialis (active substance: tadalafil).
  • Vardenafil.
  • Tadalafil (generic alternative to Cialis).
  • Sildenafil (generic alternative to Viagra).

How to use the Erectile Dysfunction Sample Pack

The ED pills in the sample pack belong to a group of medicines called phosphodiesterase type 5 (PDE 5) inhibitors. These medicines work by relaxing the blood vessels in the penis. This allows the blood to flow into the penis more easily and temporarily restores men’s ability to get an erection.

These types of ED pills will not help if you do not have erectile dysfunction, a condition in which a man has difficulty getting or maintaining an erection. Bear in mind that they work only with sexual stimulation.

The pill should be taken about 30 minutes (Cialis, Tadalafil, Vardenafil) to an hour (Viagra, Sildenafil) before sexual activity. The pills can be taken with or without food. It may take longer for the pill to take effect if it is taken with food.

The effect of the ED pills lasts several hours:

  • Viagra, Sildenafil and Vardenafil: about four to five hours.
  • Cialis and Tadalafil: up to 36 hours.

During this time, you may achieve an erection with sexual stimulation. See the package leaflet for more information on the use of the ED pills.


Do not takemore than once a day. The recommended starting dose in adult men is:

  • Viagra and Sildenafil: 50 mg.
  • Vardenafil, Cialis and Tadalafil: 10 mg.

Your doctor may adjust the dose if you feel the effect is too weak or too strong. ED pills are not intended for use by women and adolescents under the age of 18. For more information on dosage, see the package leaflet of the ED medicine you are using.


These types of ED medicines may cause side effects that will impair your ability to drive. If you experience symptoms such as dizziness or blurred vision, you should avoid driving or operating machinery until these symptoms have passed.

Limit your alcohol intake! Alcohol may trigger or intensify the side effects of ED medicines. Drinking alcohol can also temporarily impair your ability to get an erection.

If you use more/forget to use ED pills

If you take more pills than you were told to, consult your doctor or pharmacist.

The ED medicine should be taken 30 minutes to an hour before sexual activity as it needs some time to work. If you forgot to take your pill, you should take it as soon as you remember. Bear in mind it may take up to 30 minutes to get a firm erection. Never take a double dose. Do not take more than once a day.

When not to use ED pills

The ED pills in the sample pack are not suitable for everyone. You should not use these ED medicines if:

  • You are allergic to the active substance or any other ingredient in the medicine.
  • You are taking medicines called nitrates, as the combination may lead to a dangerous fall in your blood pressure. Tell your doctor if you are taking these medicines which are often given for relief of angina pectoris (or 'chest pain'). If you are unsure, ask your doctor or pharmacist.
  • You are taking products that release nitrogen monoxide, such as amyl nitrite (‘poppers’). This too can result in dangerously low blood pressure.
  • You have a serious heart or liver problem.
  • You have had a recent stroke or heart attack, or have low blood pressure.
  • You have a rare hereditary eye condition called retinitis pigmentosa.
  • You have ever had loss of vision because of nonarteritic anterior ischemic optic neuropathy (NAION).

For more information on warnings, see the package leaflet of the ED medicine you are using.

When should these types of ED medicines be used with caution?

In some situations, you should talk to your doctor before using ED medicines. For instance, if:

  • You have leukaemia, sickle cell disease, multiple myeloma (Kahler’s disease), or any deformation of your penis or undesired or prolonged erections lasting more than four hours.
  • You have a serious liver or kidney problem.
  • You have any hereditary eye disease.
  • You have any heart problems other than your pulmonary hypertension.
  • You have blood pressure problems.

For more information on warnings, see the package leaflet of the ED medicine you are using.
