My 9 year old grandson ran a high fever for a few days last week with no other symptoms other than no appetite. Tylenol reduces the fever and it went away after a couple of days. He came home from school yesterday with 101 fever that quickly went away.

My 9 year old grandson ran a high fever for a few days last week with no other symptoms other than no appetite. Tylenol reduces the fever and it went away after a couple of days. He came home from school yesterday with 101 fever that quickly went away.

Time to see doc: For fevers over 100-101 that last more than 4 or 5 days, I strongly recommend seeing his doc. Usually, the fevers with uncomplicated viral illnesses like colds go away within 3-4 days, so the fact that he had high fevers last week and now this week is more concerning. ...Read more

Can I take arthrotec for back pain and tylenol (acetaminophen) to reduce fever at the same time?

Shouldn't need to: Although technically, you can take a non-steroidal anti-inflammatory drug like Arthrotec and Tylenol (acetaminophen) at the same time as they have no significant interactions, it should not be necessary. The Arthrotec you take for your back pain should also reduce your fever. The fewer medicines you take to accomplish your goal, the better off your detoxification systems (liver & kidneys) will be. ...Read more

10month baby has fever range from 100 to 102.5.also Saw doctor prescribed ibuprofen & Tylenol (acetaminophen).can I use ice pack to reduce hot in his head, bathe him?

Yes but: fever isn't a bad thing. It is part of the body's way of fighting infection. It is good to treat the fever, because having a fever feels awful, but the fever won't "cook his brain" or anything bad like that. Alternate tylenol (acetaminophen) and ibuprofen as your doctor suggests, and if his symptoms worsen or don't improve, see your doctor again. Hope this helps! ...Read more

14month old son. How much Tylenol (acetaminophen) to give when fever? Current temp is 99.8

What weight?: To give the most precise dose you need to do it based on weight. Typically for tylenol (acetaminophen) you want to give 10-15 mg/kg per dose every 4-6 hrs as needed. However, I don't think your child needs tylenol (acetaminophen) for a temp of 99.8. Of course if your child looks uncomfortable you can try a dose. ...Read more

Can I give tempra or tylenol (acetaminophen) to bring down his fever?

Weight based meds: Both tylenol (acetaminophen) (acetomenophen) and advil (ibuprofen) have age and weight based dosing for children with fever. Luke warm bath splashing can also help--do not use ice water or alcohol baths!
of course, finding the reason for the fever is most important, so if the child is ill, they should be evaluated by the doctor. Do not give Aspirin to children under 18, to avoid reye's syndrome, a bad liver dzz. ...Read more

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

My son is 95 lbs and 5 ft tall but is only 8 can I give him 500 mg Tylenol (acetaminophen) for his fever?

Tylenol (acetaminophen) dose: The tylenol (acetaminophen) dose is 10-15 mg per Kg of body weight, your son's weight Is about 43 Kg so 500 mg of tylenol (acetaminophen) is in the range. You can give him liquid tylenol (acetaminophen) 160 mg per 5 ml, he gets 2.75 tsp every 4- 6 hours for fever or pain as needed. I hope that answers your question. Best wishes. ...Read more

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

My son got his 4 month shots yesterday and his fever hasn't gone away with Tylenol (acetaminophen). What else can I give him?

Tylenol (acetaminophen): Make sure it is the right dose which is 10 mg/kg every 4hrs
generally after shots the fever should respond and should last only 24hrs.
you could try ibuprofen 10 mg /kg every 6 hrs but if fever is still not responding in 24 hrs baby needs to be checked

Call her MD: Try to lower her fever by giving the appropriate dose of tylenol (acetaminophen) every 4 hours. Check her temp 4 hours after the last dose and if it is still high, you give another dose of tylenol (acetaminophen). Have her dr tell you what dose you should be giving.

Fever of 100.9 from last week went down, but after 4 days it's back up to 99.1? Should I be worried? I thought I wasn't sick anymore... Took tylenol (acetaminophen).

Not fever.: Temperature of 100.9 is a low to moderate fever but 99.1 is not a fever. Do you have any other symptoms besides fever like cough, cold, vomiting, diarrhea etc.? If not why do you have a need to take daily temperatures? Please stop taking temperature everyday if you are not feeling sick anymore. ...Read more

For pain or fever: You can give Tylenol (acetaminophen) to anyone in the appropriate dose for weight whether or not they have fever. Pain from immunizations or teething would be examples of pain no fever.

When giving Tylenol (acetaminophen), ask why you are giving the Tylenol (acetaminophen) and what is it you want to happen? If the baby is crying, 99 times out of 100 Tylenol (acetaminophen) is not going to help. As you already know, babies cry for a variety of reasons. ...Read more

If he/she is miserable, not drinking and/or uncomfortable this is a good time to give a fever reducer for comfort, and not to just reduce a number. ...Read more

Call you doctor: It's never a good idea to post questions about an acute illness your child is dealing with online because there can be a delay in getting an answer. In general, you're better off discussing these illnesses with your physician's office because sometimes there are other things going on that merit immediate attention. ...Read more

Can my 10 year old who weighs 155 pounds take an adult dose of tylenol (acetaminophen) if he has a fever?

Yes: In this case weight is more important than age in determining dose. But I advise against taking anything to lower fever unless he is miserable, as fever is a key aspect of how our bodies fight infections- our immune system works better and bacteria ; viruses have difficulty surviving high temps. Reducing fever sabotages your immune system and prolongs the infection! Treat discomfort, not fever. ...Read more

My 9 month old has had a fever ranging from 101-102.2. I have given h tylenol (acetaminophen) and tried to keep him cool. Can I do anything else?

You don't need to: I'm more interested in how a baby is acting than how high the fever is. If she is drinking well, wetting diapers well, not too cranky, then the fever is her immune system working and doing its job. If she appears to be in pain, won't drink, isn't wetting diapers, is vomiting repeatedly, having trouble breathing etc., then seek medical attention. The fever alone is not dangerous. ...Read more

I've had on/off fever for months, but now it's been 11 days w/o relief with aleve/tylenol. Begins a few hours after I wake and I feel terrible. Ideas?

CIDP management: In my review, I did not find fever as a manifestation of cidp. However, cidp is an immunological disorder that makes you more susceptible to infections. You need to see the physician who is treating your cidp for an evaluation. If he (she) has no new suggestions, ask for a referral to an infectious disease specialist. ...Read more

Is it ok that I gave my 2 month old tylenol (acetaminophen) a couple hours after he had his shots? He doesn't have a fever but I suspect he's in pain.

You can, but. . .: You can certainly give your kiddo tylenol (acetaminophen) after his immunizations. The dose in 15 mg per kilogram of weight every 4 hours. The tylenol (acetaminophen) will certainly help with the pain, however we also know it will decrease the overall immune response to the immunization. What this means long term is not known, but does make me tell my patient not to use tylenol (acetaminophen) unless there is fever or obvious signs of pain. ...Read more
