How long should it take for a fever to go away after taking tylenol (acetaminophen)?

How long should it take for a fever to go away after taking tylenol (acetaminophen)?

Fever: Fever is the body's way of fighting infection so it is not really a bad sign. Fever will break when a viral infection runs its course( 3 to 10 days) or when the bacterial infection succumbs to the antibiotic (24 to 72 hours). So the fever may not break after 4 hours - the expected duration of action of acetaminophen. ...Read more

3rd old fever not going down after 50 min of tylenol (acetaminophen). How long usually take for med to work? 

3rd old fever not going down after 50 min of tylenol (acetaminophen). How long usually take for med to work? 

Should be OK: 50 minutes is sufficient time for tylenol (acetaminophen) to begin to reduce a child's fever if it is going to do so. The question is whether this is really necessary? Is the baby uncomfortable from the fever itself, or is it you who feels uncomfortable having a child with fever. Fever, if tolerable, may be beneficial in the management of infection by our immune system. ...Read more

What is the best way to break fever for my 3 year old? Also will tylenol (acetaminophen) weakening his immune system in the long run?

What is the best way to break fever for my 3 year old?  Also will tylenol (acetaminophen) weakening his immune system in the long run?

It is fever!: Anything over 100.5 is fever. If the child is acting normal you can watch and re check the temp. If no other symptoms and fever lasts for more than 3 days see the doctor. Tylenol (acetaminophen) helps to relieve the symptom but does not do anything to the underlying problem. Tylenol (acetaminophen) does not affect the immune system but i would give the correct dose occasionally for short term fever or pain relief. ...Read more

See your FamilyDoc: So the good news is that Motrin & Tylenol (acetaminophen) can break your fever. The bad news is that you're still sick after 4 days. Best recommendation I can make is to see your Family Doc or go to Urgent Care or even Emergency Department to determine cause of fever & to receive appropriate treatment. ...Read more

My 11 month old son has been running a fever for the past 4 days. Highest temp has been 101.2. Motrin and tylenol (acetaminophen) break the fever, but it keeps coming back. He is teething. Should we take him to a doc?

Teething Help: Many infants show signs of distress during teething. The exact mechanism these symptoms occur during teething is not known, but the correlation of these stress symptoms with a tooth erupting remain high. Ibuprofen, cold teething rings and/or camilia can help. Try to keep fluid intake high. Ibuprophen will help with the elevated temp. And with discomfort. If it doesn't improve see your pediatrician. ...Read more

Is it better to take tylenol (acetaminophen) or motrin for a fever?

Is it better to take tylenol (acetaminophen) or motrin for a fever?

Either: Tylenol (acetaminophen) is an antipyretic so it is helpful with fever. Ibuprofen is an anti-inflammatory and addresses both fever and inflammation. With stubborn fevers people often alternate tylenol (acetaminophen) (every 4 hours) and Ibuprofen (can be taken every 6 hours). Some people find one works better than the other for them. Be sure you are drinking well when taking ibuprofen. ...Read more
