Diabetes Medications and New Drugs

Cialis (Tadalafil)

What is Cialis?

Cialis or Tadalafil is an oral medication for the treatment of erectile dysfunction. It works in a similar way to other tablets for ED such as Viagra and Levitra.

How does Cialis work?

Cialis belongs to a group of medicine called phosphodiesterase type 5 inhibitors. Blood vessels in the penis fill with blood to produce an erection. These chemicals help blood vessels in the penis relax, which helps the flow of blood. This results in improved erectile function. Cialis will be of no benefit if you do not have erectile problems. It is also important to realise that Cilais will not work if there is no sexual stimulation.

Who should not take Cialis?

You should avoid taking Cialis if

  • you are taking nitrates for treatment of angina (includes nitrolingual spray)
  • you have had a heart attack or stroke recently
  • you have low blood pressure or uncontrolled high blood pressure

What is the dose of Cialis?

Your doctor will advise you on how to use this medication. The recommended starting dose is one 10 mg tablet before sexual activity. If this does not work your doctor may increase the dose to 20 mg.

What time do I take the tablet?

Cialis may be taken at any time between 12 hours to half-an-hour before sexual activity. It may in fact be effective for up to 24 hours after taking the tablet. It is very important to realise that the tablet will not work if there is no sexual stimulation such as foreplay. In other words spontaneous erections should not occur.

What are the side effects of Cialis?

  • headache
  • indigestion
  • back pain, muscle aches
  • nasal congestion
  • facial flushing
  • dizziness
  • rarely, swelling of the eyelids, painful eyes or red eyes

Does it affect fertility?

This was encountered in one animal study. There has been no evidence that it does so in humans.
