Precautions

It is very important that your doctor check your progress while you are using this medicine. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it. If your cough does not improve or if it gets worse within 5 days, call your doctor.

It is against the law and dangerous for anyone else to use your medicine. Keep your unused capsules or oral liquid in a safe and secure place.

This medicine may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.

Do not use this medicine if you are using or have used an MAO inhibitor (MAOI) such as Eldepryl®, Marplan®, Nardil®, or Parnate® within the past 14 days.

Using this medicine can cause severe constipation. To prevent this, your doctor may direct you to take laxatives, drink a lot of fluids, or increase the amount of fiber in your diet. Be sure to follow the directions carefully, because continuing constipation can lead to more serious problems.

This medicine may make you drowsy. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

This medicine will add to the effects of alcohol and other CNS depressants (medicines that can make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicine, other prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics. Check with your doctor before taking any of these medicines while you are using this medicine.

If you think you or someone else may have taken an overdose of this medicine, get emergency help at once. Signs of an overdose include: pale or blue lips, fingernails, or skin, confusion, difficult or troubled breathing, irregular, fast or slow, or shallow breathing, extreme sleepiness or drowsiness, cold and clammy skin, or lightheadedness or fainting.

Dizziness, lightheadedness, or fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem. Also, lying down for a while may relieve the dizziness or lightheadedness.

Using this medicine while you are pregnant may cause serious unwanted effects, including neonatal opioid withdrawal syndrome in your newborn baby. Tell your doctor right away if you think you are pregnant or if you plan to become pregnant while using this medicine.

This medicine may cause adrenal insufficiency. Check with your doctor right away if you have darkening of the skin, diarrhea, dizziness, fainting, loss of appetite, mental depression, nausea, skin rash, unusual tiredness or weakness, or vomiting.

If you are especially sensitive to the effects of this medicine, do not suddenly stop using it without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help reduce the possibility of withdrawal symptoms, such as abdominal or stomach cramps, anxiety, fever, nausea, runny nose, sweating, tremors, or trouble sleeping.

Using too much of this medicine may cause infertility (unable to have children). Talk with your doctor before using this medicine if you plan to have children.

Make sure any doctor or dentist who treats you knows that you are using this medicine.
