Cialis is a prescription medication primarily used to treat erectile dysfunction (ED) and certain urinary conditions in adult men. The active ingredient in Cialis is tadalafil, which belongs to a class of medications known as phosphodiesterase type 5 (PDE5) inhibitors.
Cialis helps increase blood flow to specific areas of the body, particularly the penile region, which may support improved erectile function during sexual stimulation. The medication is also prescribed for benign prostatic hyperplasia (BPH), a condition involving an enlarged prostate gland that can cause urinary difficulties.
One of the most recognized features of Cialis is its long-lasting effect, which may remain active for up to 36 hours in some individuals.
The most common use of Cialis is for managing erectile dysfunction. Men experiencing difficulty achieving or maintaining an erection may benefit from the medication’s ability to improve blood circulation during sexual activity.
Cialis is also approved for treating symptoms associated with BPH, including:
Frequent urination
Weak urine stream
Difficulty starting urination
Incomplete bladder emptying
In some cases, healthcare providers prescribe Cialis for men who experience both erectile dysfunction and enlarged prostate symptoms simultaneously.
Cialis works by inhibiting the PDE5 enzyme, which helps relax smooth muscles and improve blood flow in targeted areas of the body. Increased blood circulation to the penile tissue may support stronger and longer-lasting erections when sexual stimulation occurs.
The medication may also relax muscles in the bladder and prostate, helping reduce urinary symptoms linked to BPH.
Cialis tablets for as-needed use are commonly available in:
5 mg
10 mg
20 mg
These doses are typically taken before anticipated sexual activity.
For daily treatment, lower-dose tablets are often prescribed, including:
2.5 mg
Daily dosing allows the medication to remain consistently active in the body.
Healthcare providers determine the appropriate dosage based on medical condition, response to treatment, and overall health history.
The primary active ingredient is:

Patients with allergies or ingredient sensitivities should review medication labeling carefully before use.
Cialis received approval from the U.S. Food and Drug Administration in the early 2000s for the treatment of erectile dysfunction. Over time, additional approvals were granted for BPH and pulmonary arterial hypertension under different formulations.
Because of its effectiveness and extended duration of action, Cialis became one of the most widely recognized ED medications worldwide.
Cialis is taken orally with or without food. Depending on the prescribed treatment plan, patients may take the medication either daily or as needed before sexual activity.
Take exactly as prescribed
Swallow tablets whole with water
Avoid taking more than recommended
Follow timing instructions carefully

The medication may remain effective for an extended period, so dosage schedules should always be followed carefully.
Several medications and substances may interact with Cialis and increase the risk of side effects or complications.
Potential interacting substances include:
Nitrate medications
Blood pressure medications
Alpha-blockers
Certain antifungal drugs
HIV protease inhibitors
Other erectile dysfunction medications
Excessive alcohol consumption may increase dizziness or blood pressure changes while taking Cialis. Grapefruit products may also affect how tadalafil is processed in the body.

Cialis tablets are commonly recognized by their distinctive appearance.
Common characteristics include:
Yellow or light-colored tablets
