acetaminofén

Acetaminophen, also known as paracetamol, is a widely used medication for the relief of mild to moderate pain and fever. It is a member of the aniline class of drugs and works by inhibiting the production of prostaglandins, which are chemicals that cause pain and fever. Acetaminophen is available over-the-counter in many countries and is also prescribed by healthcare professionals.

The typical dosage for adults is 500 to 1000 milligrams every 4 to 6 hours, not to exceed 4000 milligrams in a 24-hour period. For children, the dosage is based on their weight and age, as determined by a healthcare provider. Acetaminophen is generally considered safe when used as directed, but it can be toxic if taken in large amounts or for extended periods.

One of the most serious risks associated with acetaminophen is liver damage, particularly when taken in high doses or by individuals with pre-existing liver conditions. The risk of liver damage can be reduced by not exceeding the recommended dosage and by avoiding alcohol while taking the medication. Other potential side effects include allergic reactions, skin rash, and gastrointestinal upset.

Acetaminophen is generally well-tolerated, but it is important to follow the instructions provided by a healthcare professional or on the medication label. If you experience any severe side effects or have concerns about taking acetaminophen, it is crucial to seek medical attention immediately.
