Ibuprofen. If you are an adult of average size 3 pills, which totals 600mg. Take with a glass of water and a little food ideally.
It takes 50 minutes for it to kick in so take it now! If you don’t have ibuprofen then take Tylenol.
Once you are past the shivers donot let your fever get out of control again. Take the Ibuprofen every 5–6 hours, before you get too hot. Also, use a cold damp washcloth and wipe down your forehead, thighs, arms and forehead if you fever continues to go up. It feels terrible, but you have to get the fever down if it is very high (over 103).
You have to wake up and take the ibuprofen to make sure you don’t let more than 6 hours go by if you are just starting something like the flu.
What are your other symptoms? Is there any reason to think it isn’t the flu and is something else that might need a doctor? I don’t go to the doctor for the flu.
