What do i do if i accidentally ingested expired brufen 20mg painkiller medicine? the nearest pharmacy is 50 miles away and i cant make the drive right now as i am suffering from extreme toothache?

Overwhelming chance nothing bad will happen and you will be OK from that. Use cloves or clove oil to the tooth till you see your dentist. Hope you feel well

The expired meds may not harm you but probably won't help either. You need to see a dentist ASAP since meds will not resolve your issues.

"Expired" means less potent with time. And Burden 20mg is am medic action for children. Pain caused by infection inflammation. OTC meds, pills, potions, mouthwashes, spells, will not cure infection. You need to see a Dentist immediately. This will not get better by itself. You also need regular Dental care to reduce the chance of this happening to another tooth in the future.
