The proper way to use
Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often than directed, and do not take it every day for several days in a row. If the amount you are to take does not relieve your headache, check with your doctor. If a headache medicine is used too often, it may lose its effectiveness or even cause a type of physical dependence. If this occurs, your headaches may actually get worse. Also, taking too much acetaminophen can cause liver damage.
This medicine works best if you:
- Take it as soon as the headache begins. If you get warning signals of a migraine, take this medicine as soon as you are sure that the migraine is coming. This may even stop the headache pain from occurring.
- Lie down in a quiet, dark room until you are feeling better.
People who get a lot of headaches may need to take a different medicine to help prevent headaches. It is important that you follow your doctor's directions, even if your headaches continue to occur. Headache-preventing medicines may take several weeks to start working. Even after they do start working, your headaches may not go away completely. However, your headaches should occur less often, and they should be less severe and easier to relieve, than before. This will reduce the amount of headache relievers that you need. If you do not notice any improvement after several weeks of headache-preventing treatment, check with your doctor.
