Mucinex use and side effects

  Articles

Mucinex is a registered trademark of a medicine called guaifenesin. In the United States, guaifenesin is sold without a prescription as expectorant a remedy that can be used to treat congestion through fission and dilute the mucus in the chest and throat. Ooze, which is closer to liquid than solid, it is easier to cough and excrete. Mucinex is commonly used by people who overload because they suffer from common cold, flu or allergies, but may be prescribed by a doctor for other reasons. Guaifenesin helps relieve the symptoms of these conditions, but is not a means of addressing the underlying cause of stagnation or reducing the overall time of these diseases. Guaifenesin is safe to use in both adults and children.

In addition to its use as an expectorant, guaifenesin is a centrally acting muscle relaxant and is sometimes used in veterinary medicine for this purpose. There is also an informal treatment known as guaifenesin protocol for fibromyalgia, which is sometimes used, however, there is very little evidence to support the use of guaifenesin in this way.

Guaifenesin is sold alone or as one of several ingredients in many cough and cold medicines. Some of the various medications that contain guaifenesin include:

  • Mucinex
  • Mucinex DM – contains dextromethorphan as cough suppressant
  • Mucinex D-contains pseudoephedrine as a decongestant for sinuses and nasal
  • Mucinex Fast-Max-contains Tylenol for pain and fever, phenylephrine as decongestant and dextromethorphan
  • Infant Mucinex with multiple symptoms: several combinations listed above

Dose

Mucinex comes in a variety of forms, including tablets, liquids, and even soluble granules. You should carefully follow the instructions on the package, regardless of the form of medication you use. Talk to your healthcare provider or pharmacist and tell them about any medications you are currently taking, as well as any drug allergies you have, before trying Mucinex. If you use an extended-release medication, the tablets should not be cut, crushed, or chewed, but taken whole. You should drink plenty of water with this medicine. This medicine can usually be taken with or without food.

The typical dose of Mucinex for adults is 1 to 2 tablets of 600 mg every 12 hours, or 1 tablet of maximum strength (1200 mg) every 12 hours. When prescribing Mucinex, children should closely follow the instructions on the package, as the dose will vary depending on the age and weight of the child, as well as the medication used. Mucinex should not be given to children under 4 years of age.

You should consult your health care provider before taking this medication if you are pregnant or breastfeeding, have kidney or liver disease, or if your cough may be caused by an upper respiratory tract infection or allergies such as emphysema or COPD.

side effects

Guaifenesin is generally well tolerated and considered safe to use, but like all medications, it can cause side effects. The most common side effects associated with this drug are:

  • Queasy
  • Vomit

Less common side effects of this medication include but are not limited to:

  • Drowsy
  • Skin rash
  • Headache

You should stop taking this medication and seek emergency medical attention if you experience symptoms of a serious allergic reaction to this medication, which may include:

  • Swelling, itching, or redness of the face
  • Swelling of the tongue
  • Difficulty speaking or breathing
  • Rash or hives

You should also see your health care provider if your cough continues for more than 7 days or if it is accompanied by a fever that does not go away.

Alternative

Mucinex has little evidence that it has a powerful effect in helping you clear secretions. Some of the above combinations also contradict intuition. For example, Mucinex DM has a cough suppressant when you should try to dilute your secretions and remove excess mucus with coughing. Care should always be taken when taking combinations of medications that may decrease the effectiveness of other medications.

Proper hydration with water is an important factor in helping to reduce the incidence of thick secretions that are then difficult to cough. If you find it difficult to cough up a thick discharge, your healthcare provider may prescribe a hypertensive solution (7%) or bronchodilator (for example, Atrovent). There are many other medications that can help, but they are usually designed for chronic problems related to cystic fibrosis, chronic COPD, and other respiratory diseases.
