01 / BASIC INFORMATION

Cialis and tadalafil

Cialis is a brand of medicine containing tadalafil. It is used to treat erectile dysfunction and, in some patients, urinary symptoms associated with benign prostate enlargement.

02 / BASIC INFORMATION

Why is sexual stimulation necessary?

Inhibiting the PDE5 enzyme helps achieve an erection during sexual stimulation. The medicine does not cause an erection on its own and is not a treatment to increase sexual desire.

03 / BASIC INFORMATION

How many hours does the effect last?

Tadalafil's effect may last up to 36 hours. A continuous erection is not expected during this period. The response may vary according to health and the treatment regimen.

04 / BASIC INFORMATION

Erectile dysfunction and sexual desire are not the same

Difficulty achieving or maintaining an erection is different from reduced sexual desire. Sometimes these conditions occur together. Stress, fatigue, diabetes, vascular disease and some medicines can contribute to erection problems. If the problem recurs, its cause should be assessed rather than focusing only on choosing a medicine.

05 / BASIC INFORMATION

Know the limits of treatment

Cialis does not treat prostate cancer. Urinary symptoms suggesting prostate enlargement can also occur in other conditions, so a doctor's assessment is important. A medicine helping a symptom does not mean it automatically eliminates the underlying cause.

06 / BASIC INFORMATION

How are treatment options assessed?

Tablets are not the only option for erectile dysfunction. The doctor may consider lifestyle changes, psychological support and other treatments when necessary. If a medicine taken for another condition contributes to the problem, any change must be made only with your doctor.

07 / BASIC INFORMATION

Questions you can ask your doctor

You can note these questions before the appointment:

  • What assessments are needed to identify the cause of my problem?
  • Do the medicines I take affect the choice of treatment?
  • How often should we assess the effect and side effects?
