Introduction

Tadalafil is one of the commonly used medications that help improve men's health in several medical conditions. It is known for its strong effectiveness and long duration of action compared to similar treatments. This medication belongs to a group of drugs called PDE5 inhibitors, which work by improving blood flow in the body.
Originally developed to treat erectile dysfunction in men, Tadalafil later became used in other conditions such as benign prostatic hyperplasia (BPH) and certain cases of pulmonary arterial hypertension.
Thanks to its long-lasting effect, many patients prefer it because it provides extended results and can be taken either as needed or in low daily doses as prescribed by the doctor. In this article, we explore the main information about Tadalafil, its benefits, how to use it, and the precautions needed for safe and effective use.

What Is Tadalafil?

Tadalafil is a medication that belongs to a class of drugs known as PDE5 inhibitors, which work by improving blood flow inside the blood vessels. It is mainly used to treat erectile dysfunction in men by enhancing blood flow to the genital area in the presence of sexual stimulation.
In addition to this common use, Tadalafil is also used to treat benign prostatic hyperplasia (BPH), helping relieve symptoms such as difficulty urinating or weak urine flow. It may also be prescribed in certain cases of pulmonary arterial hypertension because it relaxes the blood vessels in the lungs and improves circulation.
This medication is known for its long duration of action, which may last up to 36 hours in some cases.

How Does Tadalafil Work?

Tadalafil works by increasing blood flow to the penis to help a man achieve an erection, but it does not cause an erection on its own and requires sexual stimulation.
It belongs to a group called PDE5 inhibitors—an enzyme found in the blood vessels of the penis. When PDE5 is inhibited, the levels of a substance called cGMP increase. This substance relaxes the smooth muscles in the blood vessels, allowing them to widen and improve blood flow, which results in a stronger and more stable erection.
Tadalafil also helps relax the muscles of the prostate and bladder, easing symptoms of BPH, and contributes to treating pulmonary hypertension by dilating the blood vessels in the lungs.

Recommended Dosage of Tadalafil

The recommended dosage of Tadalafil depends on the patient’s overall health, the condition being treated, and the presence of any other medications or medical issues.
For erectile dysfunction, it can be taken in two ways:

• As needed: starting with 10 mg before sexual activity, adjustable to 20 mg or 5 mg depending on the response.
• Daily use: typically 2.5–5 mg once daily at the same time.
  For benign prostatic hyperplasia (BPH), the usual dosage is 5 mg once daily.
  For pulmonary hypertension, dosing is more specific and should be determined by a specialist.
  It is important not to increase or repeat the dose without medical supervision, as Tadalafil may interact with medications such as heart and blood pressure drugs.

When Should You Consult a Doctor Before Using Tadalafil?

A doctor should be consulted before using Tadalafil in several conditions. This includes heart diseases such as angina, heart failure, irregular heartbeats, or a recent history of heart attack or stroke. Caution is necessary for those taking nitrate medications for chest pain, as combining them with Tadalafil can cause severe drops in blood pressure.
Medical advice is also essential if you have severely high or low blood pressure, kidney or liver disease, or a history of vision problems like optic nerve damage.
Caution is needed in cases of bleeding disorders, active stomach ulcers, or when using other interacting medications such as alpha-blockers, antifungals, certain antibiotics, HIV treatments, blood thinners, or herbal supplements like St. John’s Wort.
Medical consultation is also necessary for men with physical penis abnormalities, a history of painful or prolonged erections, sickle cell anemia, multiple myeloma, or leukemia.

Can Tadalafil Be Taken with Other Medications?

Tadalafil may interact with some medications; therefore, consulting a doctor before use is essential.
The drug must never be taken with nitrate medications used for chest pain, as this can lead to dangerous drops in blood pressure.
It may also interact with certain prostate medications such as alpha-blockers, strong antibiotics like clarithromycin, antifungal medications such as ketoconazole, HIV medications, and some heart or blood pressure treatments.
Inform your doctor if you are taking blood thinners, seizure medications, or herbal supplements like St. John’s Wort, as they may reduce or alter the effect of Tadalafil.

Is Tadalafil Safe for Women?

Tadalafil is not approved for use in women, and they should not take it, as its safety and effectiveness have not been proven in females.
Most clinical studies were conducted on men for erectile dysfunction and BPH—conditions that do not apply to women.
It can cause unwanted side effects and may pose risks during pregnancy or breastfeeding.

What Is the Best Time to Take Tadalafil?

The best time to take Tadalafil depends on how it is prescribed.
For as-needed use, it is recommended to take it 30 minutes to 1 hour before sexual activity, and its effect can last up to 36 hours.
For daily use, it should be taken at the same time every day to maintain a consistent level in the body.
It can be taken with or without food.

Conclusion

Tadalafil is an effective medication that has proven useful in treating erectile dysfunction and benign prostatic hyperplasia when used correctly and under medical supervision. Misuse may lead to complications or drug interactions, especially in patients with cardiovascular conditions. Understanding how Tadalafil works, its dosage, precautions, and interactions helps ensure safe and effective treatment.
