Cialis, known by its generic name tadalafil, is a prescription medication primarily used to treat erectile dysfunction (ED) and symptoms of benign prostatic hyperplasia (BPH), or an enlarged prostate. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors, which work by increasing blood flow to the penis to help achieve and maintain an erection. Cialis is notable for its long duration of action, offering up to 36 hours of effectiveness, which has earned it the nickname "The Weekend Pill." It is taken orally, with or without food, and should be used as directed by a healthcare provider. Cialis is also sometimes prescribed for the treatment of pulmonary arterial hypertension (PAH) under the brand name Adcirca.
When using Cialis, a medication primarily prescribed for the treatment of erectile dysfunction, it is crucial to adhere strictly to the doctor's instructions and thoroughly read the label that accompanies the medicine. Patients should inform their healthcare provider about all other medications they are taking to avoid potential interactions. Common side effects of Cialis include headaches, indigestion, back pain, muscle aches, flushing, and stuffy or runny nose, which usually resolve within a few hours. However, there are rare but serious side effects such as sudden vision loss or an erection lasting more than four hours (priapism), which require immediate medical attention. Due to its effects on the cardiovascular system, caution is advised when engaging in activities such as driving or operating heavy machinery until you know how Cialis affects you. The importance of following the doctor's guidance cannot be overstated to ensure the safe and effective use of Cialis.
