Cialis is a well-known medicine that is used to treat Erectile Dysfunction (ED). However, ED patients must be cautious when taking Cialis, as it may reduce their blood pressure.
Low blood pressure is a concerning problem because it can disrupt blood flow to vital organs, causing symptoms like fatigue and blurred vision.
Therefore, understanding the true relationship between Cialis and blood pressure is important for safe and effective treatment, allowing you to make informed choices about your health.
So, let us explore the answer to: Does Cialis lower blood pressure? We will also look at other side effects of Cialis and provide tips to avoid them.
Can Cialis lower blood pressure
Yes, low blood pressure is a rare side effect of taking Cialis. A study states that the medicine can reduce systolic blood pressure by 4.8 mmHg.
Cialis (Tadalafil) is classified as a Phosphodiesterase Type 5 (PDE5) inhibitor. It blocks the PDE5 enzyme and increases cyclic Guanosine Monophosphate (cGMP) levels, which is a chemical that regulates penile blood flow. This action can relax blood vessels in the penis, promoting a firm and lasting erection.
However, the relaxation of the blood vessels can also result in a mild blood pressure-lowering effect.
Therefore, individuals with low blood pressure (Hypotension) should be careful and only use Cialis after consulting a doctor, as the pill can reduce blood pressure.
It can also increase the chances of other Cialis side effects like headache, flushing, vision problems, Priapism (long and painful erection), and more.
The side effects are mostly temporary and may go away on their own. However, your doctor may prescribe other ED pills if they are persistent.

- Antihypertensives
Inform your medical history to the doctor during the consultation to avoid the above interactions and side effects.
