You can take up to 4000mg a day of tylenol. So it's perfectly safe to take extra strength.
thats all i have too and the doc said its fine as long as you don't go over 4000mg in one day. I usually only take one depending on how bad my headache or whatever is and 2 if the ache is really bad. So id say it'd be safe to take two at a time like LosingmymindinGA and Clysta said
I also only took Extra Strength (2 at a time). On my sheet they gave me, it says you can take up to 4000 mg of Tylenol a day. Basically all Tylenol products are safe, such as Reg Tylenol, Tylenol Extra Strength and all Tylenol Cold medicines.
it should be safe to take up to 1000 mg every 4-6 hours. The only difference between regular and extra strength is the milligrams per dose. I only take extra strength tylenol and took it while I was pregnant at my docs recommendation,.
