I think I took 4 Tylenol pm pills instead of 2 when I was getting ready for bed. Is this ok?

I think I took 4 Tylenol pm pills instead of 2 when I was getting ready for bed. Is this ok?

Tylenol overdose: It depends on when you had your last dosage, the current state of your liver, and the number of milligrams you took. 4 Grams within 24 hours is concerning. If you feel weak, nauseous, and have abdominal pain you should definitely get yourself
evaluated as soon as possible. You should follow up with your physician regardless. Following directions as prescribed is crucial to preventing an overdose. ...Read more

Mgt: I would recommend seeing your physician or the ED. Does she have any symptoms currently? When did the ingestion occur? I would also suggest calling poison control. ...Read more

I took 4 extra strength tylenol (acetaminophen) In 4 hours is that ok?

I took 4 extra strength tylenol (acetaminophen) In 4 hours is that ok?

Probably OK: Extra strength Tylenol (acetaminophen) are 500 mg, so 4 of them is 2000 mg. The usual safe recommended maximum daily dose is 3000 mg in 24 hours. If there is underlying liver or kidney disease or other medications that interact, even 2000-3000 mg can be too much. The other issue to consider is the need for Tylenol (acetaminophen). If there is a new pain that needs to be evaluated, see your doctor. ...Read more

What to do if I just took 3 or 4 tylenol (acetaminophen) 500 mg at once, is it bad?

No benefit: Your liver will be able to handle this without a problem. But something you don't want to do again as there is no benefit. Safe doses are up to 7, 000 mg/day, taken down to 3, 000 mg/day to 4, 000/day for population safety reasons. You just won't get any more added benefit from 2 grams of tylenol (acetaminophen) at a time than say from 1 gram. ...Read more

Cold&mild fever. Took Tylenol, (acetaminophen)4 hours later, I would not stop sweating. BP dropped really low idk ifmachine was false err from panic. Sepsis? BPnorm now.28

Cold&mild fever. Took Tylenol, (acetaminophen)4 hours later, I would not stop sweating. BP dropped really low idk ifmachine was false err from panic. Sepsis? BPnorm now.28

Not sepsis: Often times the presence of sweating is the sign of the fever "breaking". BP changes for various reasons but panic will usually cause increase in blood pressure. Surely sepsis will cause low BP but sepsis is a "hospital diagnosis" …you wouldn't be asking questions via the internet if you were septic. Hope this helps ...Read more

I took 2500 mg of tylenol (acetaminophen) at once about three or four hours ago; should I be concerned?

I took 2500 mg of tylenol (acetaminophen) at once about three or four hours ago; should I be concerned?

Yes and No: You have taken a whole day's worth of tylenol (acetaminophen) at once. Usually, the recommendation is 3000-4000mg per day in divided doses. It would be better to take 1000mg at breakfast, lunch, and dinner to spread it out. Instead, what you've done is deliver one whopping dose of tylenol (acetaminophen) to metabolize all at once. It's like pollution - you don't want to overwhelm the system! ...Read more

I have an elevated ALT it's 61... Is that to high to take 650mg of Tylenol (acetaminophen) every four hours?

No: Tylenol (acetaminophen) is only a liver poison at very high doses. You do need to find out why your ALT is elevated. It may be nothing more than your body asking for more exercise, but more serious illness needs to be ruled out ...Read more

My four year old son had surgery two days ago and now he has a rash. He is on Tylenol (acetaminophen) with codeine he has had four doses before the rash started.

My four year old son had surgery two days ago and now he has a rash. He is on Tylenol (acetaminophen) with codeine he has had four doses before the rash started.

Call your doctor: The best course of action is to call your doctor immediately and let him know about the rash. Tylenol (acetaminophen) can cause severe skin reactions and in addition since your son was in surgery he should be evaluated right away for any infectious causes of a skin rash as well.
I would advise taking him in immediately. ...Read more

My 6 month old son got his 6 months shot on Thursday and is still running fever between 100 and 103.giving Tylenol (acetaminophen) every four hours. Urine test - ve.

48 hours of fever: Poor baby! This timeline is definitely in the realm of fever related to vaccines. I would decide according to how the baby is looking after a dose of motrin. If he perks up and gives you a smile with a dose of motrin, then you can watch him tonight. If he appears ill, is not feeding well, or is hard to console, then bring him to the ER now. ...Read more

Four year old fever at 103.5. Doctor said tylenol (acetaminophen) and motrin back and forth but fever persist. How can I break/reduce this fever?

Four year old fever at 103.5. Doctor said tylenol (acetaminophen) and motrin back and forth but fever persist. How can I break/reduce this fever?

Cool compresses: If the fever is only for one day, even that high, you can still observe him if he is well hydrated, not lethargic & has no other symptoms. Also you ned to make sure that he is getting the right dose of fever reducers & how often you give him the dose. It could be just due to viral illness. Your child's overall condition will help to decide as well. Speak to your Pediatrician. ...Read more

My four year old son developed a fever and severe headache yesterday and it continues this morning. No other symptoms thus far. I have given Advil and tylenol (acetaminophen). Do I take him to the pediatrician?

My four year old son developed a fever and severe headache yesterday and it continues this morning. No other symptoms thus far. I have given Advil and tylenol (acetaminophen). Do I take him to the pediatrician?

Yes: He needs to get checked out especially with "severe" headache with the fever. Even more concern with neck stiffness and confusion. It is most likely a virus, but you have listed a couple of symptoms that can go with meningitis. Either way, it's worth getting it evaluated unless he miraculously starts feeling better. ...Read more

I took 2 500 mg Tylenol not thinking about if I had taken 2 when I went to bed. Now I'm afraid I've taken 4 500 mg within an hour and a half of each?

I took 2 500 mg Tylenol not thinking about if I had taken 2 when I went to bed. Now I'm afraid I've taken 4 500 mg within an hour and a half of each?

Tylenol: In this particular case, you’re likely in okay shape. 4 grams is the daily dose limit for someone of your age who has a healthy liver. With that said, you’ll want to be extra careful in future now that you’ve had this scare. Do you need to be taking Tylenol regularly? You should be taking it for as short as possible for whichever condition you’re treating. If it’s not working, something more effec ...Read more

I had 2 Tylenol extra strength @ 6:30 pm yesterday 7/28 I took 2 more @ 1:10 a.m 7:29 Is it safe to take 2 Tylenol Extra Strength Rapid release now?

Likely ok: If this is for a day or two, the dose is probably ok. Do note that any dose higher than that may cause liver problem for some people. Long-term intake of tylenol is not a good idea however due to the liver issue. ...Read more

I have a cold and yesterday accidentally took 4000mg of APAP. I roughly took 2000mg twice 12hrs apart from each other. I took 2 500mg Tylenol and also?

See below: The max daily you should take is 4000mg. Sounds like you got 5000mg. I doubt that is going to cause a problem, but I certainly wouldn't take any more tylenol for a few days, if not a week. It is very hard on your liver. To be certain, you would need to have a tylenol level drawn. You could call poison control and ask their opinion as well. ...Read more
