If you’ve ever had the the flu, you might remember that awful achy feeling. Ibuprofen can come to the rescue when you are feeling that way. Ibuprofen is a kind of pain reliever that helps ease aches and pains. After you take ibuprofen, it keeps the nerves in your body from sending messages that say “Ow! I ache!” to your brain, so you won’t hurt as much. But remember not to take any kind of medicine without your parent’s help.
