Assuming: Assuming the er physician felt your infants fever was due to a viral illness, you can observe at home if your infant is alert, eating well, having his usual number of wet diapers every few hours, no breathing difficulty and not fussy or irritable. 99.9 is not considered a fever. No need to give tylenol (acetaminophen) for 99. Always call your regular physician to see if a trip to the er is needed. ...Read more

I overdosed on 30, 000 mg Tylenol as a kid, I've had cholestasis and hepatic fits ever since, I feel terrible but blood work looks good, why is that?

Liver toxicity: Tylenol overdose is very common and can be fatal. It can lead to liver failure. Disorders of the liver can cause cholestasis. It appears the Tylenol overdose may have caused liver damage. I highly suggest you have regular check-ups in a clinic or private physicians office. ...Read more

I take hctz for high blood pressure and tylenol (acetaminophen) after 1 hour I start trembling and get cold. What is wrong with me.

I take hctz for high blood pressure and tylenol (acetaminophen) after 1 hour I start trembling and get cold. What is wrong with me.

Recheck BP: Tylenol (acetaminophen) does not interact with hctz. I wonder if you feel that way because your blood pressure drops too low 1 hour after the hctz. Check your blood pressure before hctz, then recheck it 1-2 hours after hctz both while your standing and laying down. If its below 90/60 it is too low. ...Read more

Depends on reason: You should be fine by now but the reason is important. Was this directed by your medical provider or was this a dosage you decided for yourself. In the future ask your provider if you are instructed to take more than 8 in 24 hours as to why. If you self-decided this dose in the future check with your medical provider before you start to take them to ensure the reason matches the dosage. ...Read more
