Tadalafil - Uses, Sideeffect, Precausion from Emily Zoeau's blog


Tadalafil is a medication used to treat erectile dysfunction (ED) and certain other medical conditions. It belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Tadalafil works by increasing blood flow to the penis during sexual stimulation, which helps a man achieve and maintain an erection.


Here are some key points about tadalafil:


Brand Names:

 Tadalafil is sold under various brand names, with Cialis being one of the most well-known.


Erectile Dysfunction:

It is primarily prescribed to men who have difficulty getting and maintaining an erection. It can be taken as needed or on a daily basis, depending on the specific prescription.


Pulmonary Arterial Hypertension (PAH):

Tadalafil is also used to treat a condition called pulmonary arterial hypertension, which involves high blood pressure in the arteries of the lungs.


Duration of Action:

Tadalafil is known for its long duration of action. It can work for up to 36 hours, earning it the nickname "the weekend pill." This means a man can take it well in advance of sexual activity and not be restricted to a specific short window of time.


How it Works:

Tadalafil inhibits the action of the PDE5 enzyme, which breaks down a chemical called cyclic guanosine monophosphate (cGMP) in the body. cGMP is responsible for relaxing the smooth muscles in the blood vessels of the penis, allowing increased blood flow, which is necessary for an erection.


Side Effects:

Common side effects of tadalafil may include headache, flushing, indigestion, muscle aches, and back pain. More serious side effects are rare but can include sudden vision loss, hearing loss, and prolonged erections (priapism).



Tadalafil should not be taken with certain medications, especially those containing nitrates, as it can cause a dangerous drop in blood pressure. It's important to consult a healthcare provider before taking tadalafil, especially if you have any underlying medical conditions or are taking other medications.


Generic Versions:

Generic forms of tadalafil are available and may be more affordable than the brand-name versions.


Consult a Healthcare Provider:

Tadalafil should only be used under the guidance and prescription of a qualified healthcare provider. They can determine the appropriate dose and frequency based on an individual's medical history and needs.

Remember that tadalafil is a prescription medication, and its use should be discussed with a healthcare professional who can provide personalized advice and monitor for potential side effects or interactions with other medications.
