Paracetamol works differently depending on what is wrong with the body. In the event of an injury, it blocks the signals to the brain that tell the body that there is pain.
Meanwhile, during a fever, paracetamol targets the areas of the brain that regulate body temperature. The pain reliever can be used for all kinds of conditions, including backaches, headaches, migraines, and stomachaches.
However, like all medicines, there are some side effects, albeit rare, to taking paracetamol.
Some of them are manageable, others require immediate medical attention. One of these is the skin turning pale yellow; this is also known as jaundice. If this happens, contact a doctor immediately.
This is not the only side effect that should result in a call to a medical professional. If breathing is difficult, irregularly fast or slow, or shallow, you should consult a doctor.
The NHS recommends that you also seek emergency treatment if you experience a serious allergic reaction. An allergic reaction to paracetamol can come in the form of a rash with "itchy, red, swollen or blistered skin". /Telegraph/
