Mucinex Side Effects: The Good And Bad Side Effects You Need To Know

October 10, 2018 By Nell Simmons

Coughing and congestion will rain on anyone’s parade. While allergies or a common cold are not much to worry about in most cases, they still leave you feeling tired and unable to carry out your day-to-day responsibilities with the same ease and comfort you are used to. The expectorant medication commonly known as Mucinex may provide you with the relief you are looking for. However, before you choose Mucinex to relieve your symptoms, take a few minutes to learn about what Mucinex is and familiarize yourself with the good and bad Mucinex side effects. Only then can you weigh the benefits and risks to make the best decision to relieve your own cough and cold symptoms. 

Mucinex Uses And Side Effects

MucinexD MAX STRENGTH Allergy and Sinus Congestion Relief that Works

Mucinex is a brand name for a medication called guaifenesin. In the United States, guaifenesin is sold over-the-counter expectorant that can be used to treat congestion by breaking up and thinning mucus in the chest and throat. Mucus that is closer to a liquid than a solid is easier to cough out and expel. Mucinex is typically used by individuals who are congested because they are suffering from a common cold, the flu, or allergies but it can be prescribed by a doctor for other reasons. Guaifenesin works to relieve the symptoms of these conditions but is not a treatment for the root cause of congestion or decrease the overall time of these illnesses. Guaifenesin is safe to use in both adults and children.

Aside from being used as an expectorant, guaifenesin is a centrally-acting muscle relaxant and is sometimes used in veterinary medicine for this purpose. There is also an off-label treatment known as the fibromyalgia guaifenesin protocol that is sometimes used, however, there is very little evidence to support the use of guaifenesin in this manner.

Guaifenesin is sold by itself or as one of the several ingredients in many cough and cold preparations. Some of the different medications containing guaifenesin include:

Mucinex 24

Sally Found that NAC helped ease her upper respiratory tract challenges:

I have had COPD for several years . My lungs are the weak link in an otherwise healthy body.

I take NAC and find that it helps break up things and clear my lungs and stop the nagging, little cough that is caused by COPD. Recently, I had a bad bout of pneumonia and bronchitis for which I took Mucinex. It was helpful but when I went back to the NAC things got better.immediately.

Linda found that Mucinex plus a neti pot nasal rinse eased her symptoms:

I had never had a sinus infection until I was in my early 60s and didnt know what they were. Then I got sick for weeks at a time. Finally I figured it out and went to a doctor for relief.

Id been taking OTC cold tablets that didnt help at all and seemed to make it worse. I got so stuffed up and impacted that I couldnt breathe through my nose at all and didnt think Id ever get better. The doctor told me to only take a med with guaifenesin as the main ingredient. Around the same time I read about neti pots.

From then on whenever I got a cold I took Mucinex with guaifenesin and used the neti pot to try and ward off getting a sinus infection. This has been a very successful regimen for me. I still get an occasional cold, maybe once a year, but they are milder now and dont last as long.

Mucinex D can raise your blood pressure. Make sure your provider knows if you have heart problems or high blood pressure before you start taking it.

What Is The Correct Dosage Of Mucinex D

How To Get Rid Of Your Sinus Congestion!! A Real “Mucinex D” Review… (Sinus Relief)

The Mucinex D Extended Release 12-Hr tablet is to be taken orally by mouth. You can either have it with food or without food. It is to be taken every 12 hours with a full glass of water or as per your doctors instructions. If you notice a stomach upset after having Mucinex D, then it is recommended you take the medication with food or milk. If you are self-treating with Mucinex D, then it is important to follow all the instructions in the product package. It is advisable that you dont consume the medication close to bedtime as it can cause problems in sleeping.

The dosage of Mucinex D is based on your age, your medical condition, and your response to the treatment. However, whatever the case, you should not take more than two doses in a day and do not increase your dose more than what is given in the instruction package.

Swallow the capsules whole and do not try to open them. Do not chew or crush the capsules/tablets. Crushing or chewing the tablet/capsule will release the entire drug at one go and increase the risk of side effects as well.

While taking Mucinex D, continue to drink plenty of water or fluids as this will further help in dissolving or breaking up mucus and phlegm, clearing away the congestion. Also, avoid consuming caffeine while on Mucinex D as it can increase the side effects of this drug. Therefore, avoid beverages such as coffee, colas, tea, as well as large amounts of chocolate. Also, do not take nonprescription medications that contain caffeine.

What Happens If I Miss A Dose

Since cough or cold medicine is taken when needed, you may not be on a dosing schedule. If you are taking the medication regularly, take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What Symptoms Does It Treat

Mucinex, or guaifenesin, treats the symptoms of a cough and chest congestion caused by colds, allergies, infections, and other short-term respiratory sicknesses. While it controls the symptoms of these illnesses and offers temporary relief, Mucinex does not treat the cause. As mentioned before, Mucinex will not cure your illness or shorten its duration.

Why Do Some Medications Dehydrate You

There is a difference between actual dehydrating medications and those that give you a dried-out sensation, says Jennings. The goal of a diuretic is to remove excess fluid from the body, which can lower blood pressure and reduce swelling in the extremities. Dehydration would only occur if such a medication removed too much fluid from the body. Talk to your doctor if you’re concerned.

Medications that dry you outantihistaminescause that side effect because they block a specific neurotransmitter in the brain, Jennings says. 

Many patients experience drying side effects because they are taking too many antihistamines. “For example, if someone is taking a daily antihistamine for allergy symptoms and currently suffering from cold/flu symptoms, they might take a multi-symptoms product that results in a duplication of antihistamine,” Jennings says.

Jennings gives the example of someone taking a daily antihistamine to fight seasonal allergies who then comes down with the common cold. 

If they continue to take their daily allergy medication and introduce a product like NyQuil for overnight cold relief, they are doubling up on antihistamines and are more likely to experience extreme dryness. Many consumers aren’t aware of what’s in their medications or how their medications may interact, Jennings adds.
