Have you experienced the tremendous pain of fracturing a bone? Well, fear no more! Hydrocodone is a pain reliever that can help in the relief of very severe pain. Although it can help to relieve immense pain, make sure to follow a doctor's instructions as even a little extra can cause problems. Pain relievers like Ibuprofen can be used to reduce both severe and little pain, but on the other hand, hydrocodone is only prescribed to treat those who are in severe pain and can't be treated in other ways. So always make sure to ask a doctor first! A hydrocodone molecule consists of 21 hydrogen atoms, 18 carbon atoms, 3 oxygen atoms, and one nitrogen atom.
