Over-the-counter (OTC) medications can be helpful when you come down with a cough, cold, or fever. Mucinex (guaifenesin), Nyquil, and Dayquil are just a few common OTC products that you may have in your medicine cabinet to provide relief.

But if you're experiencing multiple cough and cold symptoms, you may need more than just one of these products. In that case, can you take Mucinex and Nyquil together? And what about combining these medications with OTC pain relievers, like Tylenol (acetaminophen) or Advil (ibuprofen)? Below, we discuss the dos and don'ts of combining multiple OTC medications for symptom relief.

What is the difference between Mucinex and Nyquil?

Mucinex and Nyquil are both medications that can be used for cough and cold symptoms. Their ingredients and uses differ slightly. So one may be preferred over the other, depending on your symptoms.

Mucinex and Nyquil ingredients can vary by product. And there are a number of different dosage forms available, including oral pills and liquids. Always check your specific product's label since the medication may contain ingredients that are different from what's discussed below.

What is Mucinex?

Mucinex is a medication that's used for chest congestion. It contains the active ingredient guaifenesin. Guaifenesin is an expectorant, which means it works by breaking up mucus in the airways. This allows you to cough up mucus more easily and to clear your airways.

Another version of Mucinex is Mucinex DM. It contains guaifenesin and another active ingredient: dextromethorphan. Dextromethorphan is used to help relieve coughing. Mucinex DM is used to treat a cough associated with mucus in the chest.

What is Nyquil?

Nyquil is a combination medication used to treat cold and flu symptoms such as cough, sore throat, and headache. It can also help with fever, runny nose, and sneezing.

Nyquil products typically contain the following active ingredients, which all have different purposes:

• Acetaminophen: a pain reliever and fever reducer

• Dextromethorphan: a cough suppressant

• Doxylamine: an antihistamine that can help with congestion and sneezing

How is Nyquil different from Dayquil?

Typically, Nyquil is taken at night before you go to bed, and Dayquil is taken during the day.

Dayquil is similar to Nyquil, except Nyquil contains doxylamine, which causes sleepiness. And unlike most Nyquil products, Dayquil contains phenylephrine. Phenylephrine is a nasal decongestant that's intended to help with nasal and sinus congestion and pressure.

Sometimes, decongestants like phenylephrine can make it harder for people to sleep. That's why phenylephrine is left out of Nyquil, which is formulated to help with sleep.

Aside from phenylephrine, Dayquil products typically also contain acetaminophen and dextromethorphan. But like Nyquil, Dayquil ingredients can vary by product.

Can you take Mucinex and Nyquil or Dayquil together?

Many OTC cough, cold, and flu medications contain similar ingredients. In general, you'll want to avoid taking medications that contain overlapping ingredients.

Always check with your prescriber or pharmacist before taking OTC medications together. They can help you avoid taking products with duplicate ingredients. And they can check for potential interactions with other medications or supplements you're taking.

Mucinex and Nyquil

Mucinex and Nyquil don't typically share any of the same active ingredients, and they don't interact with each other. So taking these two medications together should be safe for most people.

However, Mucinex DM contains dextromethorphan, which is also found in Nyquil. Taking Mucinex DM and Nyquil together could result in too much dextromethorphan in your system, leading to side effects like dizziness and drowsiness. This combination should be avoided.

Mucinex and Dayquil

In most cases, it's safe to take Mucinex and Dayquil together since their active ingredients don't typically overlap or interact. However, there are Dayquil cough products that contain guaifenesin. Taking one of these products with Mucinex could result in taking too much guaifenesin.

Like with Nyquil, you should avoid taking Dayquil with Mucinex DM because they both contain dextromethorphan.

Can you take Mucinex with Tylenol or Advil?

In addition to taking a medication like Mucinex, some people with cold and flu symptoms might also need to take a pain reliever. Tylenol and Advil are common OTC medications used for pain relief. They're both helpful at reducing common cold and flu symptoms like body aches, sore throat, and fever. But is it safe to take these OTC pain relievers with Mucinex?

Mucinex and Tylenol

The only active ingredient in Mucinex is guaifenesin. Since Mucinex doesn't contain any type of pain reliever, it should be safe to take with Tylenol. However, ask your pharmacist or prescriber before combining these medications if you have any medical conditions, such as liver disease, or take additional medications.

Mucinex and Advil

As mentioned above, Mucinex doesn't contain a pain reliever, so it should be safe to take with Advil as well.

Can you take Nyquil with Tylenol or Advil?

Since Nyquil contains several active ingredients, taking it with an OTC pain reliever is a little more complicated.

Nyquil and Tylenol

Nyquil contains acetaminophen, the active ingredient in Tylenol. Combining Nyquil and Tylenol could result in taking too much acetaminophen. This can lead to serious problems like liver damage or even death.

One study showed that about 50% of people are likely to take too much acetaminophen when combining multiple OTC acetaminophen-containing products. The FDA also warns against taking too much acetaminophen from OTC products, especially if you have liver problems or drink a lot of alcohol.

Most adults shouldn't take more than 4,000 mg of acetaminophen in a day. And the daily maximum can also vary by product. For some people, the recommended amount may be even less. This includes people with liver problems or heavy alcohol use.

Always check with your pharmacist or prescriber before combining OTC products that contain acetaminophen. They can make sure you're taking a safe amount.

Nyquil and Advil

Advil is a common pain reliever that contains the active ingredient ibuprofen. Advil and Nyquil don't interact with each other. But it may not be necessary to take these two medications at the same time. That's because Nyquil already contains the pain reliever acetaminophen.

But if you're finding that you need additional pain relief, it's generally OK to take generic ibuprofen or Advil with Nyquil. Talk to your prescriber or pharmacist about the safest way to combine these medications.

Can you take Dayquil with ibuprofen?

Similar to Nyquil, it's generally OK to take Dayquil with generic ibuprofen or Advil. But Dayquil also contains acetaminophen, so you may not need to take another pain reliever with it. If you need more pain relief, though, your healthcare team can help you combine these medications safely.
