The highest dosage to drinking Ibuprofen (38) at once can lead to death. Ibuprofen helps lower fever and minor pain. Overdosing may cause damage to the stomach and intestines since drinking a lot at once. Just know that Ibuprofen is a nonsteroidal anti-inflammatory drug, and it isn't to play with since this is deadly. People who take this but doesn't have heart disease or any risk factors can get these problems. Stay safe :)
