3. Why not use Aspirin and Ibuprofen in dengue fever?



Aspirin is a drug with antipyretic and analgesic effects at high doses and antiplatelet aggregation at lower doses. However, aspirin is contraindicated in dengue fever.

In addition, aspirin also causes burning of the gastrointestinal tract, respiratory failure, especially causes bronchospasm and aggravates asthma.
Group of non-steroidal anti-inflammatory drugs (NSAIDs) besides Aspirin, there are also diclofenac, ibuprofen, piroxicam... Especially Ibuprofen is often used to reduce pain and inflammation for patients with fever. Although the platelet aggregation effect of these drugs is not as strong as aspirin, this property still exists to varying degrees, so the risk of bleeding that is difficult to stop in dengue fever still occurs.
Therefore, Ibuprofen and other NSAIDs are not recommended for the symptomatic treatment of dengue.

Carefully read the instructions for use, do not overdose, do not use in combination with drugs containing the same active ingredient paracetamol because it can easily lead to an overdose. Paracetamol for children has many dosage forms (tablets, oral syrups, powders, nuggets, effervescent tablets and suppositories), do not use a combination of different routes of administration, only one dosage form is used to avoid the risk of drug poisoning causing liver damage, impaired liver function. Before using the drug should combine cool compress, rest in a well-ventilated place, drink enough water. Monitor body temperature regularly Look for signs of dengue fever to quickly visit the hospital. Do not take consecutive doses of paracetamol over a period of less than 4 hours.
