Obredon

hydrocodone / guaifenesin
Used for Cold Symptoms, Cough

Obredon is a combination medication that helps relieve cough and chest congestion in adults. It contains hydrocodone (an opioid that works like a cough suppressant to lower the urge to cough) and guaifenesin (an expectorant that thins mucus in the chest). This medication comes as a flavored liquid that's taken by mouth every 4 to 6 hours as needed for cough and congestion. Side effects can include constipation and making you sleepy. This medication is a controlled substance because it contains an opioid with a risk for misuse and addiction.

Risks and warnings for Obredon (hydrocodone / guaifenesin)

Obredon (hydrocodone / guaifenesin) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Potential for misuse and addiction

  • Risk factors: Personal or family history of alcohol or substance use disorder | Personal or family history of mental health conditions (like depression)

Black Box Warning Obredon contains hydrocodone, which is an opioid that carries a risk of addiction and misuse, even at recommended doses. For this reason, Obredon (hydrocodone / guaifenesin) is a schedule II controlled substance. In serious cases, addiction and misuse of an opioid medication can lead to overdose and death.

blank warning iconObredon (hydrocodone / guaifenesin) is typically prescribed only when cough relief outweigh these serious risks. If absolutely necessary, your healthcare professional (HCP) will prescribe the lowest amount of medication for the shortest period of time needed to treat your symptoms. Contact your HCP to discuss other options if you've taken Obredon (hydrocodone / guaifenesin) for 5 days and your cough hasn't gotten better.

Dangerously slow breathing (respiratory depression)

  • Risk factors: Older adults | Children younger than 18 years old | Taking medications that can cause slow breathing | Brain injury | Drinking alcohol | Having medical conditions that affect breathing (e.g., asthma) | Taking higher doses of Obredon (hydrocodone / guaifenesin) than prescribed

Black Box WarningThe hydrocodone in Obredon can cause dangerously slow breathing, which can be life-threatening. This can happen at any time, but you're at higher risk 1 to 3 days right after you start Obredon (hydrocodone / guaifenesin). Drinking alcohol and taking other medications, like benzodiazepines, can also raise your risk for this dangerous side effect.

blank warning iconYou're recommended to ask your prescriber about getting naloxone, a medication that can reverse slowed breathing from opioids. You should have naloxone before you start Obredon (hydrocodone / guaifenesin) so that you can use it in case of an accidental overdose. Call 911 to get medical help right away if you or a loved one notices that you have trouble breathing or bluish-colored lips.

Difficulty concentrating and extreme sleepiness

  • Risk factors: Taking higher doses of Obredon (hydrocodone / guaifenesin) | Age 65 years or older | Drinking alcohol | Taking other medications that can cause sleepiness

Black Box Warning The hydrocodone in Obredon can cause extreme sleepiness. It can also lower your ability to think, react, and focus. Your risk for these side effects is higher if you're taking other medications that can make you sleepy, such as benzodiazepines, muscle relaxants, and sleep medications.

blank warning iconMake sure you know how Obredon (hydrocodone / guaifenesin) affects you before driving a car or doing activities that require your concentration. Talk to your HCP right away if you feel too sleepy from the medication.

Risk for opioid overdose

  • Risk factors: History of opioid use disorder | Previous opioid overdose | Taking high doses of Obredon (hydrocodone / guaifenesin) | Taking more opioids than prescribed | Drinking alcohol

Black Box WarningTake Obredon (hydrocodone / guaifenesin) exactly as prescribed. Taking too much medication or taking it more often than prescribed can lead to an opioid overdose. Mixing alcohol with opioids also raises your risk for overdose. Be sure you know how to measure out your dose properly and don't drink alcohol or use alcohol-containing products while you're taking Obredon (hydrocodone / guaifenesin). Place the medication out of reach from children, pets, or visitors to prevent accidental exposure or overdose.

blank warning iconSymptoms of an opioid overdose include not responding to sound or touch, extremely slow breathing, extreme sleepiness, slow heartbeat, and cold or clammy skin. Be sure you and your loved ones know how to recognize an overdose. Your prescriber will probably recommend you to get naloxone (Narcan), a medication that can treat an opioid overdose. Have naloxone with you at all times; use it and call 911 right away if an overdose happens.

blank warning iconObredon also contains guaifenesin, which can be found in many over-the-counter cough and cold products, such as the Mucinex branded line of products. Taking too much guaifenesin can lead to side effects like upset stomach, dizziness, and headaches. To prevent an accidental overdose, read package labels carefully. Ask your pharmacist if you're not sure whether a product has guaifenesin in it.

Drug interactions

Black Box WarningObredon (hydrocodone / guaifenesin) interacts with many medications. So it's important to tell your prescriber and pharmacist about the medications you're taking and planning to take with Obredon (hydrocodone / guaifenesin). Your care team can check that your medications are safe to take together. Also talk to your care team first before making any changes to your medications because sudden dose adjustments can lead to harm as well.

blank iconSome drug interactions can raise the level of hydrocodone in your body. This can raise your risk for serious side effects, including potentially life-threatening slowed breathing. Examples of medications that can lead to this type of interaction with Obredon (hydrocodone / guaifenesin) include erythromycin, ketoconazole, and ritonavir (Norvir).

blank iconOther drug interactions can lower the levels of hydrocodone in your body. This can make the opioid work less well for cough and possibly lead to withdrawal symptoms (especially if you've been taking the cough medication for a long time). These interactions include taking Obredon (hydrocodone / guaifenesin) with rifampin (Rifadin) or carbamazepine (Tegretol).

Harm to newborn babies

  • Risk factors: Taking Obredon (hydrocodone / guaifenesin) during pregnancy

Black Box WarningIt isn't recommended to take Obredon (hydrocodone / guaifenesin) if you're pregnant. The medication can go through the bloodstream to your unborn baby. Long-term opioid use during pregnancy can cause your unborn baby to become dependent on the medication.

blank warning iconOnce your baby is born, they can experience withdrawal symptoms, such as high-pitched crying, poor feeding and sucking behavior, trembling, irritability, abnormal sleep patterns, and even seizures. This condition is called neonatal opioid withdrawal syndrome and can be life-threatening if not recognized and treated in time. Let your healthcare team know if you've taken Obredon (hydrocodone / guaifenesin) during pregnancy or if you notice these symptoms in your baby.

Low blood pressure

Obredon (hydrocodone / guaifenesin) can cause extremely low blood pressure. Your blood pressure might drop when you stand from a sitting or lying down position. This can lead to dizziness and fainting. To avoid falling, get up slowly if you've been sitting or lying down. Talk to your HCP if any dizziness or lightheadedness doesn't go away.

Low adrenal hormone levels

  • Risk factors: Taking Obredon (hydrocodone / guaifenesin) for longer than 1 month

Some people who take opioid medications, like the hydrocodone in Obredon, can have low adrenal hormone levels. This can be more likely to happen after taking opioids for longer than 1 month. Tell your HCP if you have symptoms, such as tiredness, dizziness, weakness, not feeling hungry, nausea, and vomiting. If your adrenal hormone levels are too low, you might need to stop the medication and get treated with corticosteroids.

Caution in people with gut-related conditions

  • Risk factors: Also taking anticholinergic medications like ipratropium or antihistamines

It's not recommended to take Obredon (hydrocodone / guaifenesin) if you have a blockage in your gut (bowel obstruction) or if you have any conditions related to gut movement. This is because the hydrocodone in Obredon can cause the movement in your gut to slow. This can lead to constipation, bowel obstruction, or worsening of a gut condition you already have. Get medical attention right away if you experience symptoms related to bowel obstruction, such as serious stomach pains, bloating, or nausea.

Seizures

  • Risk factors: History of seizure conditions

Opioids, such as the hydrocodone in Obredon, can raise the risk of having seizures more often in people who've had one in the past. Obredon (hydrocodone / guaifenesin) can also raise your risk for seizures in certain other situations. Get medical help right away if you have a seizure while you're taking this medication.

Pharmacist tips for Obredon (hydrocodone / guaifenesin)

pharmacist
  • Take Obredon (hydrocodone / guaifenesin) exactly as prescribed. Take it as needed only when you're having cough or chest congestion symptoms and take each dose at least 4 to 6 hours apart.
  • Talk to a healthcare professional (HCP) for other options if your cough doesn't get better after you've taken Obredon (hydrocodone / guaifenesin) for 5 days. You should take this medication only for a short period of time because it can be habit-forming and it has many serious risks.
  • Use the medication dose cup or oral syringe that your pharmacy gives you to measure out your dose of Obredon (hydrocodone / guaifenesin). Don't use household teaspoons or utensils because they're not accurate, so you might end up taking the wrong dose and be at risk for an overdose.
  • Obredon (hydrocodone / guaifenesin) can make you sleepy and dizzy. It can also make you have trouble focusing or concentrating. Avoid activities that need your full attention, like driving, until you know how the medication affects you.
  • Avoid drinking alcohol or using any alcohol-containing products while you're taking Obredon (hydrocodone / guaifenesin). Alcohol can worsen side effects like sleepiness and dizziness. Both alcohol and Obredon (hydrocodone / guaifenesin) can also make it hard for you to think clearly and react quickly.
  • You might get constipated after you take Obredon (hydrocodone / guaifenesin). To help with constipation, drink enough water each day and add more foods with fiber, like broccoli and beans, to your diet. Speak to your care team if you need more relief. They can recommend medications or a change in your treatment.
  • Let your prescriber and pharmacist know about all the medications you're taking to make sure Obredon (hydrocodone / guaifenesin) is safe to take with them. Several medications can interact with both hydrocodone and guaifenesin, and these drug interactions can be harmful. Also, keep in mind that guaifenesin can be found in many over-the-counter cough and cold products.
  • Talk with your prescriber if you've been regularly taking Obredon (hydrocodone / guaifenesin) for a long period of time and you want to stop. Your prescriber might lower your dose slowly over time before you can stop completely. This helps prevent withdrawal symptoms, such as anxiety, stomach cramps, and chills, which can happen after lowering your dose or stopping the medication too suddenly.
  • Keep Obredon (hydrocodone / guaifenesin) at room temperature in a safe place out of reach from children, pets, or visitors. Ask a pharmacist about how to get rid of it safely if you don't need to take the medication anymore. This lowers the risk of accidental overdose and helps prevent medication misuse.

Common questions about Obredon (hydrocodone / guaifenesin)

Yes. One of the ingredients in Obredon is hydrocodone, which is an opioid. Hydrocodone works in the brain to lower the urge to cough. The other ingredient is guaifenesin, an expectorant that thins the mucus in your lungs so it's easier to cough out. In general, opioid-containing medications like Obredon (hydrocodone / guaifenesin) have many safety warnings. So it's important to speak with your prescriber about the risks of taking an opioid and whether this medication is an appropriate option for you.

Both the hydrocodone and guaifenesin in Obredon generally start to help relieve cough and congestion within 30 minutes of taking a dose. Let your care team know, though, if your cough doesn't get better within 5 days of starting the medication. This might be a sign that you need something different for the type of cough or congestion you have. It's recommended to visit a healthcare professional to get examined again at this point. Continuing Obredon (hydrocodone / guaifenesin) will just raise your risk for dependence and other serious side effects, like trouble breathing. Speak with your healthcare team if this medication doesn't seem to be relieving your cough or congestion enough.

Yes. Sleepiness is a common side effect of opioids like the hydrocodone in Obredon. Your risk for this side effect is higher if you're taking other medications that make you sleepy, such as benzodiazepines or muscle relaxants. Also, you can feel even sleepier if you drink alcohol while you're taking Obredon (hydrocodone / guaifenesin) so avoid alcohol. Make sure to avoid driving or doing anything that requires concentration until you know how Obredon (hydrocodone / guaifenesin) affects you.

Yes, it's generally okay to take ibuprofen (Advil) with Obredon (hydrocodone / guaifenesin). This medication doesn't directly interact with ibuprofen (Advil). But keep in mind that ibuprofen (Advil) isn't safe for everyone. For example, ibuprofen (Advil) isn't a good option for people with certain medical conditions, such as heart failure or kidney problems. Before you take ibuprofen (Advil) with Obredon (hydrocodone / guaifenesin), speak with a healthcare professional or pharmacist to make sure it's safe for you to take them together.

Yes. Acetaminophen (Tylenol) doesn't have any serious interactions with Obredon (hydrocodone / guaifenesin), so it's safe to take together. But acetaminophen (Tylenol) has has a risk for causing liver problems, so it's not the best choice for everyone. Speak with a healthcare professional to make sure it's safe for you to take acetaminophen (Tylenol) with Obredon (hydrocodone / guaifenesin).

No. Mixing alcohol and Obredon (hydrocodone / guaifenesin) can be dangerous. Drinking alcohol or using products that contain alcohol while you're taking Obredon (hydrocodone / guaifenesin) can slow down your brain activity. It raises your risk of life-threatening slowed breathing, excessive sleepiness, dizziness, coma, overdose, and death. Let your prescriber know before you start taking Obredon (hydrocodone / guaifenesin) about your drinking habits so they can give you guidance.

Obredon (hydrocodone / guaifenesin) is not recommended during pregnancy because it can harm to your baby. This medication contains an opioid (hydrodocone). Opioid use during pregnancy, especially when taken for a long time, can cause your baby to have withdrawal symptoms when they're born. These symptoms include high-pitched crying, irritability, breathing problems, feeding problems, fever, or even seizures. This condition can become life-threatening if it isn't managed and treated right away. Discuss the risks and benefits of taking Obredon (hydrocodone / guaifenesin) with a healthcare professional if you're pregnant. Let your prescriber know right away if you become pregnant while you're taking this medication.

It's not recommended to take Obredon (hydrocodone / guaifenesin) while breastfeeding because it can cause harm to your breastfed baby. The hydrocodone component of this combination medication can get into breast milk. This raises the risk that your breastfed baby can have serious side effects like excessive sleepiness, slowed breathing, and even death. Let your healthcare team know if you're breastfeeding so they can discuss your options with you. They'll either recommend that you stop breastfeeding if it's absolutely necessary for you to take Obredon (hydrocodone / guaifenesin) or suggest other remedies for cough and congestion.
