Cialis is a brand-name oral medication prescribed primarily for erectile dysfunction (ED) and benign prostatic hyperplasia (BPH). Its active ingredient, tadalafil, is known for its effectiveness in increasing blood flow to the penis and relaxing the muscles in the prostate and bladder, thereby alleviating urinary symptoms associated with BPH.
The Food and Drug Administration (FDA) granted approval to Cialis in 2003, marking a significant advancement in the treatment of ED and BPH in adult males. A comprehensive understanding of the medication, including its mechanism of action, potential side effects, and appropriate dosage, is essential for patients to make informed decisions about their treatment alternatives.

How Long Does Cialis Last?
Cialis is noted for its long-lasting efficacy, providing relief for up to 36 hours. Patients may choose to take Cialis as needed, ideally 30 minutes to 2 hours prior to sexual activity, or opt for daily use, which ensures consistent levels of the medication in the body for ongoing effectiveness against both ED and BPH.
Cialis vs. Viagra
When considering treatments for erectile dysfunction, many patients compare Cialis and Viagra. While both medications effectively treat ED, they differ significantly in duration of action and specific indications.
Ingredients
The primary active ingredient in Cialis is tadalafil, whereas Viagra contains sildenafil. Both are classified as PDE5 inhibitors, functioning similarly by enhancing blood flow to facilitate an erection.
Uses
Although both drugs are FDA-approved for the treatment of ED, Cialis has additional approval for:
- Addressing symptoms of benign prostatic hyperplasia (BPH), which can include various urinary complications.
- Simultaneously treating ED and BPH symptoms.
Drug Forms and Administration
Cialis is available in oral tablet form, which can be taken either daily or on an as-needed basis. In contrast, Viagra is typically prescribed only for situational use, making the choice between medications dependent on personal preferences and lifestyle needs.
Side Effects
Both Cialis and Viagra share similar side effects due to their underlying mechanisms; however, the incidence and severity can vary between individuals.
FDA-Approved Uses for Cialis
The FDA has approved Cialis specifically for the treatment of:
Benign Prostatic Hyperplasia (BPH)
A condition commonly seen in aging males, BPH is characterized by the enlargement of the prostate gland, leading to symptoms such as:
- Increased frequency of urination, particularly during the night
- Difficulties in initiating urination
- Weak or interrupted urine stream
Erectile Dysfunction (ED)
ED is defined as the persistent inability to achieve or maintain an erection adequate for satisfactory sexual performance. By boosting blood flow to the penis, Cialis aids in the erectile process when sexual stimulation occurs.
Generic Version: Tadalafil
The generic variant of Cialis, known as tadalafil, presents a more affordable alternative without sacrificing the safety or efficacy associated with the brand-name drug.
Cost Considerations
Generic medications, such as tadalafil, typically offer patients financial relief, often costing significantly less than their brand-name counterparts. However, the precise price can fluctuate based on pharmacy location, dosage prescribed, and insurance policy.
Dosing Information
The recommended dosage of Cialis varies based on individual health conditions, including the severity of ED and BPH symptoms. Here are common dosing guidelines:
For Erectile Dysfunction:
- As Needed: The usual starting dose is 10 mg, administered approximately 30 minutes before anticipated sexual activity.
- Daily Use: A daily regimen may start with a dose of 2.5 mg, facilitating continuous treatment without the need for planning around sexual encounters.
For Benign Prostatic Hyperplasia:
The suggested dosage for managing BPH symptoms is 5 mg once daily, irrespective of sexual activity.
Possible Side Effects of Cialis
Cialis may trigger both mild and severe side effects, making it essential for patients to communicate any unexpected symptoms with their healthcare provider.
Mild Side Effects
- Headaches
- Back pain
- Facial flushing
- Congestion or stuffiness in the nasal passages
- Muscle aches
Serious Side Effects
Infrequent but severe adverse effects may include:
- A prolonged erection lasting more than 4 hours
- Alterations in vision

Effectiveness of Cialis
Research indicates that Cialis significantly enhances erectile function and reduces symptoms associated with BPH. The International Index of Erectile Function (IIEF) is often utilized in clinical studies to measure treatment success.
How to Take Cialis
Cialis should be administered in line with your doctor's prescribed instructions. It can be taken either with or without food; however, it is crucial not to exceed the recommended dose.
Taking with Food
No specific dietary restrictions exist, although excessive alcohol consumption should be avoided, as it may increase the risk of adverse effects.
Drug Interactions
Cialis has the potential to interact with various medications, which can impact its effectiveness and safety. Notable interactions include:
- Nitrates (e.g., nitroglycerin), which can lead to dangerously low blood pressure levels.
- Alpha-blockers that may also contribute to blood pressure reduction when combined with Cialis.
