Cialis contains tadalafil, a prescription medicine used to treat erectile dysfunction and, in certain dosing regimens, symptoms of benign prostatic hyperplasia. This page provides general information about tadalafil, including its uses, strengths, how it works, precautions and storage. Use tadalafil only as directed by a qualified healthcare professional.
Cialis is the brand name for tadalafil, a medicine belonging to the phosphodiesterase type 5 (PDE5) inhibitor class. Tadalafil increases blood flow to certain tissues when sexual stimulation occurs and can also relax smooth muscle in the prostate and bladder. The appropriate dose depends on the condition being treated, other medicines being used, kidney and liver function, and individual medical circumstances. A healthcare professional should determine the appropriate treatment regimen.
Tadalafil is used for the treatment of erectile dysfunction. It is also used in specific dosing regimens to treat the signs and symptoms of benign prostatic hyperplasia. Tadalafil does not automatically cause an erection and does not protect against sexually transmitted infections. Patients should follow their prescriber's instructions and discuss existing medical conditions and all medicines or supplements they take before using tadalafil.
Tadalafil inhibits the PDE5 enzyme. This increases the availability of cyclic guanosine monophosphate (cGMP), which contributes to relaxation of smooth muscle and increased blood flow. For erectile dysfunction, sexual stimulation is still necessary for tadalafil to produce its intended effect. The medicine should not be used more frequently or at a higher dose than prescribed.
The product information currently lists 5 mg and 20 mg tadalafil strengths. The appropriate strength and dosing schedule depend on the medical condition being treated and the patient's individual circumstances. Do not change the dose without advice from a qualified healthcare professional.
Tadalafil should not be taken with nitrate medicines because the combination can cause a dangerous drop in blood pressure. It should also be used cautiously with certain alpha-blockers, blood-pressure medicines and medicines that affect tadalafil metabolism. Seek urgent medical attention for an erection lasting more than four hours, sudden vision loss or sudden hearing loss. Patients with cardiovascular disease or other significant medical conditions should discuss tadalafil use with their healthcare professional before treatment. This information is for general educational purposes and does not replace professional medical advice.
Store tadalafil according to the product labeling and keep it out of reach of children. Keep medicines in their original packaging where appropriate and do not use a product that has been damaged or is past its expiration date.
