Cialis is a widely recognized prescription medication that contains tadalafil as its active ingredient. This medication is mainly prescribed for two primary health concerns: erectile dysfunction (ED) and benign prostatic hyperplasia (BPH), which is an enlarged prostate condition. As a phosphodiesterase type 5 (PDE5) inhibitor, Cialis enhances blood flow to the penis, enabling men to achieve and sustain an erection during sexual intercourse.
The FDA granted approval for Cialis to be used by adults in 2003, and since then, it has gained immense popularity as an effective treatment for both erectile dysfunction and symptoms associated with benign prostatic hyperplasia.

How Long Does Cialis Last?
One of the unique features of Cialis is its remarkably long duration of effectiveness — up to 36 hours. This prolonged action allows for greater spontaneity compared to other erectile dysfunction treatments, making it a preferred choice for many men. Depending on individual health needs and your healthcare provider's advice, Cialis can be prescribed to be taken as needed prior to sexual activity, or it can also be taken daily in lower doses.
Cialis vs. Viagra
Two of the most commonly compared medications in the realm of erectile dysfunction are Cialis and Viagra (sildenafil). Here’s how these medications stack up against each other:
Ingredients
Cialis contains tadalafil, while Viagra’s active ingredient is sildenafil. Although both belong to the same class of PDE5 inhibitors, they differ in their duration of action and how long they take to work.
Uses
Both medications are FDA-approved for the treatment of erectile dysfunction; however, Cialis has the added approval for alleviating symptoms of benign prostatic hyperplasia, which Viagra does not.
Drug Forms and Administration
Cialis can be taken either daily or only as needed before sexual engagement, while Viagra is usually prescribed strictly for on-demand use.
Side Effects
Common side effects of both Cialis and Viagra include headaches and facial flushing. However, each medication carries different risks and side effect profiles.
Effectiveness of Cialis
Research shows that Cialis is effective in enhancing erectile function. In clinical trials, men who were administered Cialis reported improved sexual confidence and higher satisfaction compared to those using Viagra. Many users have expressed a preference for Cialis due to its extended duration of action.
Cost of Cialis
The price of Cialis can vary significantly depending on factors such as insurance coverage, pharmacy location, and potential discounts. As a brand-name drug, it may be more costly than its generic version, tadalafil. It’s advisable to consult with a healthcare provider about available financial options to help manage the costs associated with this medication.
Dosage Information
Cialis is offered in several dosages, including 2.5 mg, 5 mg, 10 mg, and 20 mg. The specific dosage will depend on the patient's health condition and individual factors.
Dosage for ED
The usual starting dose for erectile dysfunction is often 10 mg taken before sexual activity. Based on how well it works and any side effects experienced, this dosage can be adjusted, with a maximum dose of 20 mg allowed. For continuous daily use, a lower dosage of 2.5 mg to 5 mg may be recommended.
Dosage for BPH
For patients with symptoms of benign prostatic hyperplasia, the standard dosage is 5 mg taken once daily. Depending on your specific needs and your doctor's recommendations, it may be taken with or without food.
Potential Side Effects
Cialis, like any medication, can produce side effects. It’s crucial to discuss these with your healthcare provider so that you can manage them effectively.
Mild Side Effects
- Headache
- Facial flushing
- Stuffy nose
- Back pain
