For those suffering from the effects of hypertension, Plan B pill is a very effective medication t control the condition. Plan B pill is belongs to the beta adrenergic classification of anti-hypertensive medication. Generally what it does is that it blocks beta receptors found in the heart that transmits too much impulse to the heart to make it beat too fast. When the heart is more relaxed and pumps blood slower, blood pressure decreases and goes back to normal levels.

However, too much Plan B pill usage can cause some effects that are not very favorable to the individual. Here is a list of side effects of Plan B pill and why do these side effects of Plan B pill occur.

Difficulty in breathing

Beta receptors are not only found in the heart, but they are also found in the lungs. These beta receptors in the lungs absorb the beta1 building block which helps the lungs expand more easily and it helps dilate the upper and lower airways, allowing more air to pass through. When these receptors are blocked, beta1 building blocks are not able to bind with their receptors. This results to the constriction of the airways that limits the air that is able to pass through; that is why the individual exerts more effort to breathe in air and exhale out the carbon dioxide. This leads to difficulty in breathing generally.

Visual disturbances

This is brought about when too many Plan B pills or a high dose of Plan B pills are given to an individual. This causes a sudden drop in blood pressure. Blood is not able to perfuse in the skull. When there is not enough blood and oxygen that goes to the occipital lobe of the brain, visual disturbances occur like blurring of vision or night blindness. It is important continually assess the individual for possible eye nerve damage.

Acute coughing

Plan B pills when taken too long and in excess can also cause to stimulate the cough reflex incessantly. This leads to coughing episodes even though there is no infection or alteration of immunity inside the lungs. Cough suppressants are usually given to persons experiencing this symptom. But it is also important to note that cough suppressants cannot be taken for long periods as well.

Erectile dysfunction

This probably one of the most dreaded side effects by men. But do not fret because erectile dysfunction brought about by the Plan B pill is temporary. Normal penile function resumes once the drug is stopped or controlled by another drug.
