Precautions While Using This Medicine

Check with your doctor :

• If the medicine stops working as well as it did when you first started using it . This may mean that you are in danger of becoming dependent on the medicine. Do not try to get better relief by increasing the dose .
• If you are having headaches more often than you did before you started using this medicine . This is especially important if a new headache occurs within 1 day after you took your last dose of headache medicine, headaches begin to occur every day, or a headache continues for several days in a row. This may mean that you are dependent on the medicine. Continuing to take this medicine will cause even more headaches later on . Your doctor can give you advice on how to relieve the headaches.

Check the labels of all nonprescription (over-the-counter [OTC]) and prescription medicines you now take . Taking other medicines that contain acetaminophen together with this medicine may lead to an overdose. If you have any questions about this, check with your health care professional.

This medicine may cause some people to become drowsy, dizzy, or less alert than they are normally. These effects may be especially severe if you also take CNS depressants (medicines that slow down the nervous system, possibly causing drowsiness) together with this medicine. Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; barbiturates; medicine for seizures; muscle relaxants; antiemetics (medicines that prevent or relieve nausea or vomiting), and anesthetics. If you are not able to lie down for a while, make sure you know how you react to this medicine or combination of medicines before you drive, use machines, or do anything else that could be dangerous if you are drowsy or dizzy or are not alert .

Do not drink alcoholic beverages while taking this medicine . To do so may increase the chance of liver damage caused by acetaminophen, especially if you drink large amounts of alcoholic beverages regularly. Also, because drinking alcoholic beverages may make your headaches worse or cause new headaches to occur, people who often get headaches should probably avoid alcohol.
