About Cialis

Cialis contains tadalafil as the active ingredient. It is commonly prescribed to treat the conditions erectile dysfunction, benign prostatic hyperplasia (enlarged prostate), and pulmonary arterial hypertension. Cialis belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors. It works by temporarily increasing blood flow through blood vessels to the penis, during periods of sexual stimulation.

Tadalafil is only available on prescription for erectile dysfunction if you have a spinal cord injury or multiple sclerosis. If you do not have these conditions you may get a private prescription.

NowPatient offers Cialis, or the non branded version tadalafil as treatments for erectile dysfunction only, following an online consultation with a prescribing clinician.

Key facts of Cialis

  • Cialis usually takes 30 to 60 minutes to work
  • Cialis can be taken 30 minutes before you want to have sex
  • Cialis does not result in an erection if taken alone. You would need to be sexually excited for it to work
  • Cialis has some common side effects which include headaches, facial flushes, feeling sick, and indigestion. Many people display no side effects, or if they do the side effects can be mild
  • It can be dangerous to take Cialis with certain medications like alpha blockers or nitrates (nitroglycerin, isosorbide mononitrate). The combination can lead to a dangerous fall in your blood pressure. If you’re not sure if you’re taking a nitrate, you can discuss this with the prescribing clinician
  • You should avoid drinking grapefruit juice if you’re taking Cialis prescribed for pulmonary hypertension because it affects the way the medicine works
