It is a prescription drug that has helped millions of men improve their sexual health and quality of life. In this article, we will delve into what Cialis is, how it works, recommended dosages, potential side effects, and other essential information. We aim to provide a detailed and expert perspective to assist you in understanding and using Cialis effectively.
What is Cialis?
Cialis, known generically as tadalafil, is a medication that belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. It was approved by the FDA in 2003 for the treatment of erectile dysfunction. Unlike its counterparts, Viagra and Levitra, Cialis is often nicknamed the “weekend pill” due to its long-lasting effects of up to 36 hours.
Mechanism of Action
Cialis works by increasing blood flow to the penis, which helps achieve and maintain an erection when sexually stimulated. It does this by inhibiting the PDE5 enzyme, which regulates blood flow in the penis. By blocking this enzyme, Cialis ensures that blood vessels remain dilated, allowing for a sustained erection.
Indications for Use
- Erectile Dysfunction (ED): Cialis is primarily prescribed to treat erectile dysfunction, a condition where a man finds it difficult to achieve or maintain an erection sufficient for sexual intercourse.
- Benign Prostatic Hyperplasia (BPH): Cialis is also used to treat symptoms of an enlarged prostate, such as difficulty in starting the flow of urine, weak stream, and the need to urinate frequently or urgently.
- Pulmonary Arterial Hypertension: In some cases, Cialis is used to treat pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the vessels carrying blood to the lungs.
Recommended Dosages
The dosage of Cialis varies depending on the condition being treated and individual patient factors. It is essential to follow a healthcare professional’s guidance when using this medication.
| Condition | Recommended Dosage |
|---|---|
| Erectile Dysfunction | 10 mg taken prior to anticipated sexual activity, not more than once per day. The dose may be increased to 20 mg or decreased to 5 mg based on efficacy and tolerability. |
| Benign Prostatic Hyperplasia | 5 mg once a day, taken at the same time each day. |
| PAH | 40 mg once a day. |
Possible Side Effects
Like all medications, Cialis can cause side effects. Most side effects are mild and temporary, but some can be serious. Common side effects include:
- Headache
- Indigestion
- Back pain
- Muscle aches
- Flushing
- Nasal congestion
Serious side effects, although rare, can include sudden vision loss, sudden hearing decrease, and an erection that lasts more than four hours (priapism). If you experience any of these, seek medical attention immediately.
Expert Opinions
