Generic Name: homatropine/hydrocodone (hye-droe-KOE-done bye-TAR-trate, hoe-MAT-roe-peen meth-il-BROE-mide)
Warning: Addiction, abuse, and misuse; life-threatening respiratory depression; accidental ingestion; medication errors; cytochrome P450 3A4 interaction; concomitant use with benzodiazepines or other CNS depressants; interaction with alcohol; neonatal opioid withdrawal syndromeAddiction, Abuse, and MisuseHydrocodone bitartrate/homatropine methylbromide exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Reserve hydrocodone bitartrate/homatropine methylbromide for use in adult patients for whom the benefits of cough suppression are expected to outweigh the risks, and in whom an adequate assessment of the etiology of the cough has been made. Assess each patient’s risk prior to prescribing hydrocodone bitartrate/homatropine methylbromide, prescribe hydrocodone bitartrate/homatropine methylbromide for the shortest duration that is consistent with individual patient treatment goals, monitor all patients regularly for the development of addiction or abuse, and refill only after reevaluation of the need for continued treatment.Life-Threatening Respiratory DepressionSerious, life-threatening, or fatal respiratory depression may occur with use of hydrocodone bitartrate/homatropine methylbromide. Monitor for respiratory depression, especially during initiation of hydrocodone bitartrate/homatropine methylbromide or when used in patients at higher risk.Accidental IngestionAccidental ingestion of even one dose of hydrocodone bitartrate/homatropine methylbromide, especially by children, can result in a fatal overdose of hydrocodone.Risk of Medication ErrorsEnsure accuracy when prescribing, dispensing, and administering hydrocodone bitartrate/homatropine methylbromide. Dosing errors can result in accidental overdose and death. Always use an accurate milliliter measuring device when measuring and administering hydrocodone bitartrate/homatropine methylbromide.Cytochrome P450 3A4 InteractionThe concomitant use of hydrocodone bitartrate/homatropine methylbromide with all cytochrome P450 3A4 inhibitors may result in an increase in hydrocodone plasma concentrations, which could increase or prolong adverse drug effects and may cause potentially fatal respiratory depression. In addition, discontinuation of a concomitantly used cytochrome P450 3A4 inducer may result in an increase in hydrocodone plasma concentration. Avoid the use of hydrocodone bitartrate/homatropine methylbromide in patients taking a CYP3A4 inhibitor or inducer.Risk from Concomitant Use with Benzodiazepines or Other CNS DepressantsConcomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Avoid the use of hydrocodone bitartrate/homatropine methylbromide in patients taking benzodiazepines, other CNS depressants, or alcohol.Interaction with AlcoholInstruct patients not to consume alcoholic beverages or use prescription or non-prescription products that contain alcohol while taking hydrocodone bitartrate/homatropine methylbromide. The co-ingestion of alcohol with hydrocodone bitartrate/homatropine methylbromide may result in increased plasma levels and a potentially fatal overdose of hydrocodone.Neonatal Opioid Withdrawal SyndromeHydrocodone bitartrate/homatropine methylbromide is not recommended for use in pregnant women. Prolonged use of hydrocodone bitartrate/homatropine methylbromide during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If hydrocodone bitartrate/homatropine methylbromide is used for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available .Oral route(Tablet)
Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Avoid use of opioid cough medications in patients taking benzodiazepines, other CNS depressants, or alcohol .

Uses for hydrocodone and homatropine
Hydrocodone and homatropine combination is used to relieve cough in adults and children 6 years of age and older. Hydrocodone is a narcotic antitussive (cough suppressant). It acts directly on the cough center in the brain to relieve cough.
When hydrocodone is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing cough and nasal congestion should not let the fear of dependence keep them from using narcotics to relieve their cough. 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.
Hydrocodone and homatropine is available only with your doctor's prescription.
Before using hydrocodone and homatropine
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For hydrocodone and homatropine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to hydrocodone and homatropine or any other medicines.

Although appropriate studies on the relationship of age to the effects of hydrocodone and homatropine combination have not been performed in the geriatric population, no geriatric-specific problems have been documented to date. However, elderly patients are more likely to have age-related kidney, liver, or lung problems, which may require caution and an adjustment in the dose for patients receiving hydrocodone and homatropine combination.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Precautions while using hydrocodone and homatropine
It is very important that your doctor check your or your child's progress while you are using hydrocodone and homatropine. 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.
Do not use hydrocodone and homatropine if you are using or have used an MAO inhibitor (MAOI) such as Eldepryl®, Marplan®, Nardil®, or Parnate® within the past 14 days.
Hydrocodone and homatropine 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 hydrocodone and homatropine.
If you think you or someone else may have taken an overdose of hydrocodone and homatropine, get emergency help at once. Symptoms of an overdose include: extreme dizziness or weakness, trouble breathing, slow heartbeat or breathing, seizures, and cold, clammy skin. In case of an overdose, call your doctor right away.
Hydrocodone and homatropine 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.
Hydrocodone and homatropine may make you dizzy or drowsy. Do not drive or do anything else that could be dangerous until you know how hydrocodone and homatropine affects you.
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.
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 hydrocodone and homatropine 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 hydrocodone and homatropine.
Hydrocodone and homatropine 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 hydrocodone and homatropine, 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 hydrocodone and homatropine may cause infertility (unable to have children). Talk with your doctor before using hydrocodone and homatropine if you plan to have children.
Make sure any doctor or dentist who treats you knows that you are using hydrocodone and homatropine. Hydrocodone and homatropine may affect the results of certain medical tests.
