Remedies to reduce fever are antipyretics or anti-inflammatory drugs, such as paracetamol or ibuprofen, which act by reducing the formation of substances that cause an increase in body temperature, especially in cases of flu or the common cold.
Fever is a way for the body to defend itself from aggressive agents such as viruses or bacteria, being an important sign that something is wrong with the body. In cases of fever that is very high, above 39ºC, or does not go down, even taking the medication, it is important to consult a doctor to verify the cause and treat it properly. See the main causes of fever.
It is important that medicines to reduce fever are used with medical indication as they have contraindications and side effects.In addition, in the case of children or pregnant women, not all remedies are indicated, and therefore, they must be used under the guidance of a pediatrician or obstetrician, with doses adapted to age, weight and the intensity of symptoms.
The medicines that are most used by the doctor to reduce fever are:
Paracetamol, also known as acetaminophen, is the antipyretic drug most indicated by doctors to reduce fever in adults or children, as it acts by reducing the production of specific substances in the body, responsible for causing fever, especially in cases of colds or flu.
