I took 1 motrin 600mg for severe toothache, 4.5 hours later after trying to wait it out unsuccessfully i took another. is that fine?next dosage:in8hrs

Not to worry: Motrin 800 mg every 8 hours with food has been the drug of choice for many of us. As a matter of fact, I have found doses of this drug used acutely (less than 7 days) have been far superior than narcotics alone. However the latest recommendations have been changed by the AMA and it is now not recommended to take more than 600mg every 8 hours. Just be careful and you'll be fine.

Med wise, fine...: ... but you really need to have that tooth examined and restored before the pain becomes unbearable and no amount of medication will help.

It is OK , See DDS: The maximum daily dose should not exceed 2,400 mg so you can take 600 mg every 4-6 hours. However, a toothache is a problem that won’t go away by itself. It can be caused by tooth decay, an infection, or a cracked tooth. Please visit a dentist ASAP.
