What It Is and How It Works
Tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor. Its mechanism of action involves relaxing the smooth muscles in the blood vessels, which enhances blood flow to certain areas of the body, including the penis. In simpler terms, this medication helps men achieve and maintain an erection by increasing blood flow in response to sexual stimulation. Unlike some treatments that must be taken immediately before intercourse, tadalafil offers flexibility due to a longer duration of action.
Indications / Uses
Cialis is primarily prescribed for erectile dysfunction, helping men achieve and maintain an erection sufficient for sexual activity. It is also indicated for benign prostatic hyperplasia, where it helps alleviate urinary symptoms associated with an enlarged prostate. In certain instances, it is used to treat pulmonary arterial hypertension, where it improves exercise ability by relaxing blood vessels in the lungs.
Dosage Forms and Typical Dosing Considerations
Cialis is available in various strengths, including 5mg, 10mg, and 20mg tablets. The usual starting dose for ED is 10mg taken before sexual activity, but it can vary based on the individual\’s response and tolerability. For BPH, a 5mg daily dosing is common. Dosing may need adjustments for those with liver or kidney impairment, and it\’s crucial to follow the exact dosing instructions provided by the prescribing healthcare professional.
How to Take It Correctly Step-by-Step
To maximize the effectiveness of Cialis and minimize side effects, adhere to the following guidelines:
- Swallow the tablet with water, with or without food.
- Take at least 30 minutes before planned sexual activity for ED.
- Avoid taking more than once a day.
- Store the medication at room temperature away from moisture and heat.
- If a dose is missed for daily use, take it as soon as you remember if it\’s within the same day.
- Do not double up doses if a dose is missed.
- Avoid consuming excessive alcohol, which can impair the ability to get an erection.
