Hydrocodone, pseudoephedrine, and guaifenesin (Oral)

Hydrocodone, pseudoephedrine, and guaifenesin combination is used to help relieve cough and stuffy nose caused by the common cold.

Hydrocodone is a narcotic cough suppressant. It works directly on the cough center in the brain to help relieve coughing. Pseudoephedrine is a decongestant that reduces nasal congestion by narrowing the blood vessels and decreasing blood flow to the nasal passages. Guaifenesin helps to clear mucus or phlegm from the chest when you have congestion from a cold or flu. It does this by thinning the mucus or phlegm in the lungs.

Using hydrocodone for a long time may lead to habit formation. This can cause mental or physical dependence. If you become physically dependent and stop treatment suddenly, you may experience unwanted withdrawal effects. Talk to your doctor if you have any questions.

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

It is very important that your doctor check your progress while you are using this medicine. This will help your doctor see if the medicine is working properly and decide if you should keep taking it. If your cough does not improve or 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 oral liquid in a safe and secure place. People who are addicted to drugs might want to steal this medicine.

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.

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

If you think you or someone else may have taken an overdose of this medicine, get emergency help right away. Signs of an overdose include: dark urine, difficult or troubled breathing, irregular, fast or slow, or shallow breathing, nausea or vomiting, pain in the upper stomach, pale or blue lips, fingernails, or skin, pinpoint pupils of the eyes, or yellow eyes or skin.

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

This medicine will increase 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.

Using this medication can cause severe constipation. To prevent this, your doctor may tell 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 ongoing constipation can lead to more serious problems.

Dizziness, lightheadedness, or fainting may happen when you get up suddenly from a lying or sitting position. Getting up slowly may help reduce this issue. 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. This medicine may affect the results of certain medical tests.

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

In deciding to use a medication, the chances of taking the medication must be weighed against the good it will do. This is a decision you and your clinician will make. For this drug, the following should be considered:

Allergies

Inform your doctor if you have ever had any unusual or allergic reaction to this medication or any other medicines. Also inform your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

The use of hydrocodone in children younger than 6 years of age has caused severe breathing problems, sometimes causing death. Use of hydrocodone, pseudoephedrine, and guaifenesin combination is not indicated in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific issues that would limit the usefulness of hydrocodone, pseudoephedrine, and guaifenesin combination in the elderly. Nevertheless, elderly patients are more likely to have age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving this drug.

Breast Feeding

There are no adequate studies in women for determining infant chance when using this drug during breastfeeding. Weigh the potential benefits against the potential risks before using this medication while breastfeeding.

Interactions with Medications

Although certain drugs should not be used together at all, in other cases two different drugs may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary.

The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
