Uses for guaifenesin and hydrocodone

Guaifenesin and hydrocodone combination is used to ease cough and nasal congestion that comes with the common cold.

Hydrocodone is a narcotic antitussive (cough suppressant). It works directly on the cough center in the brain to reduce coughing. Guaifenesin helps clear mucus or phlegm from the chest when you have congestion due to a cold or flu. It does this by thinning the mucus or phlegm in the lungs.

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

Precautions while using guaifenesin and hydrocodone

It is very important for your doctor to monitor 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 symptoms do not improve or get worse, call your doctor.

It is illegal and dangerous for anyone else to use your medicine. Keep your unused oral liquid or tablets in a safe place. People who are addicted to drugs might try to steal this medicine.

Do not use this medicine if you are currently using or have used an MAO inhibitor (MAOI) like Eldepryl®, Marplan®, Nardil®, or Parnate® in 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 guidance.

If you think you or someone else may have taken an overdose of this medicine, seek emergency help immediately. Signs of an overdose include dark urine, trouble breathing, irregular or fast or slow breathing, nausea or vomiting, upper stomach pain, pale or blue lips, fingernails, or skin, pinpoint pupils of the eyes, or yellow eyes or skin.

This medicine may make you feel dizzy or drowsy. Do not drive or do anything 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 medicines for allergies or colds, sedatives, tranquilizers, or sleeping pills, other prescription pain medicines or narcotics, medicines for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics. Check with your doctor before taking any of these medicines while using this medicine.

Using this medication can cause severe constipation. To prevent this, your doctor may recommend taking laxatives, drinking plenty of fluids, or increasing fiber in your diet. Be sure to follow the directions carefully, as ongoing constipation can lead to more serious issues.

Dizziness, lightheadedness, or fainting may occur when you get up quickly from lying or sitting. Getting up slowly may help reduce this issue. Also, lying down for a while may help 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 immediately if you think you are pregnant or plan to become pregnant while using this medicine.

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

If you have been using this medicine regularly for several weeks or longer, do not stop using it suddenly without first consulting your doctor. Your doctor may want you to slowly reduce the amount you are using before stopping it completely. This may help lessen the chance of withdrawal symptoms, such as abdominal cramps, anxiety, fever, nausea, runny nose, sweating, tremors, or trouble sleeping.

Contact your doctor right away if you have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or see or hear things that are not there. These may be signs of a serious condition called serotonin syndrome. Your risk may be higher if you also take certain other medicines that affect serotonin levels in your body.

Using too much of this medicine may cause infertility (inability to have children). Speak with your doctor before using the tablet if you plan to have children.

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.

Before using guaifenesin and hydrocodone

In deciding to use a drug, the chances of using the medicine must be weighed against the beneficial it will do. This is a decision you and your doctor will make. For this medicine, 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 medications. Also tell 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. Appropriate studies have not been performed on the relationship of age to the effects of guaifenesin and hydrocodone combination 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 guaifenesin and hydrocodone combination in the elderly. However, elderly patients are more likely to develop age-related kidney, liver, or heart problems, which may require caution and an adjustment in the dose for patients receiving this medicine.

Breast Feeding

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