Uses For Vopac

Acetaminophen and codeine oral suspension is used to relieve mild to moderate pain. The oral tablets are used to relieve mild to moderately severe pain.

Acetaminophen is used to relieve pain and reduce fever in patients. It does not become habit-forming when taken for a long time. But acetaminophen may cause other unwanted effects when taken in large doses, including liver damage.

Codeine belongs to the group of medicines called narcotic analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain.

When codeine is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.

This medicine is available only with your doctor's prescription.

Proper Use of acetaminophen and codeine

This section provides information on the proper use of a number of products that contain acetaminophen and codeine. It may not be specific to Vopac. Please read with care.

Take this medicine only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. This is especially important for elderly patients, who may be more sensitive to the effects of pain medicines. If too much of this medicine is taken for a long time, it may become habit-forming (causing mental or physical dependence) or cause an overdose. Large amounts of acetaminophen may cause liver damage.

Shake the oral suspension well before each use. Measure the medicine with a marked measuring spoon, oral syringe, or medicine cup. The average household teaspoon may not hold the right amount of liquid.

This combination medicine contains acetaminophen (Tylenol®). Carefully check the labels of all other medicines you are using, because they may also contain acetaminophen. It is not safe to use more than 4 grams (4,000 milligrams) of acetaminophen in one day (24 hours).

Precautions While Using Vopac

It is very important that your doctor check the progress of you or your child while you are taking this medicine. This will allow your doctor to see if the medicine is working properly and to decide if you or your child should continue to take it.

It is against the law and dangerous for anyone else to use your medicine. Keep your unused medicine in a safe and secure place. People who are addicted to drugs might want to steal this medicine.

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. Also, there may be a greater risk of liver damage if you drink three or more alcoholic beverages while you are taking acetaminophen. Do not drink alcoholic beverages, and check with your doctor before taking any of these medicines while you are using this medicine.

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.

Check with your doctor right away if you have pain or tenderness in the upper stomach; pale stools; dark urine; loss of appetite; nausea; unusual tiredness or weakness; or yellow eyes or skin. These could be symptoms of a serious liver problem.

This medicine may cause a serious type of allergic reaction called anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Stop using this medicine and call your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using this medicine.

This medicine may make you dizzy, drowsy, or lightheaded. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert.

Using narcotics for a long time 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.

For patients taking a codeine-containing medicine or any other narcotic analgesics (e.g., dihydrocodeine, hydrocodone, oxycodone, and pentazocine):

• Contact your doctor right away if you have extreme sleepiness, confusion, or shallow breathing. These symptoms may indicate that you are an "ultra-rapid metabolizer of codeine". Ultra-rapid metabolizers change codeine to morphine more quickly and completely than other people. As a result, there is too much morphine in the body and more side effects of morphine than usual.

Do not change your dose or suddenly stop using this medicine 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 prevent worsening of your condition and reduce the possibility of withdrawal symptoms, such as abdominal or stomach cramps, anxiety, fever, nausea, runny nose, sweating, tremors, or trouble with sleeping.

Using this medicine while you are pregnant may cause neonatal withdrawal syndrome in your newborn babies. Tell your doctor right away if your child has the following symptoms: abnormal sleep pattern, diarrhea, high-pitched cry, irritability, shakiness or tremor, weight loss, vomiting, or failure to gain weight.

Before you have any medical tests, tell the medical doctor in charge that you or your child are taking this medicine. The results of certain tests may be affected by this medicine.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines, especially those containing acetaminophen (Tylenol (R)), and herbal or vitamin supplements.
