ibuprofen will exit your system in 12-24 hours, depending on your body. the dosage doesn't effect time in your system, it just effects the potency of the drug during its duration i your body. so it may only take 12 hours to get out of your body, and the 600mg is just telling you how strong it will be in your body.
Ar poor love - I think it took about 4 weeks for us too but seemed to happen in three bouts where really bad teething with ibuprofen at night for 3 days followed by nothing for about 10days then another 3 days of teething followed by nothing until they were fully in. We are getting the 4 'eye teeth' now.
