Also, stop using acetaminophen if your child develops new symptoms such as redness or swelling on the skin. In these cases, call your doctor right away as they could be signs of a more serious condition such as a reaction to a medication.

Non-steroidal anti-inflammatory drugs (NSAIDs) include drugs such as ibuprofen, aspirin, and naproxen. This is also a group of drugs that help reduce inflammation, relieve pain, and reduce fever. The mechanism of action of NSAIDs is by preventing the body from producing a substance called prostaglandin, which in turn suppresses the inflammatory response and fever by releasing various chemical signals in the body.
NSAIDs are also formulated in a variety of ways, suitable for use on many subjects such as acetaminophen, including tablets, chewable tablets, capsules or even liquid suspension, placed rectally.
Compared with acetaminophen, NSAIDs are used to reduce fever in children less commonly because of the potential for side effects, so they are usually only combined when acetaminophen is not effective enough.
Therefore, when it is necessary to use NSAIDs to lower a child's fever, parents need to pay attention to the dosage and how to use it, to avoid an overdose.
The most common side effect of NSAIDs is stomach upset. To help prevent stomach upset, take ibuprofen or naproxen with food or milk and not on an empty stomach. Furthermore, NSAIDs can also have many serious side effects, including:
Damage to the lining of the digestive tract, causing bleeding and ulcers. Cardiovascular damage, causing heart attack and stroke. Kidney damage. Allergic reactions to the drug with symptoms such as difficulty breathing, wheezing, swelling of the face, and shock.

The child's fever is increasing or persists for more than three days . Skin redness or swelling. Tinnitus or hearing loss. Signs of stomach bleeding, including: Pale skin, vomiting blood or what looks like coffee grounds, bloody or black stools, stomach pain that doesn't improve.
