Mucinex Information

Mucinex (Guaifenesin) is an over-the-counter medication that relieves chest congestion and cough caused by the common cold, bronchitis, and other respiratory illnesses. The active ingredient in Mucinex is Guaifenesin. Expectorants such as Guaifenesin stimulate secretions in the respiratory tract, increasing the volume and reducing the viscosity of mucus in the trachea and bronchi. Mucinex loosens mucus in the airways through this mechanism, clearing congestion and improving respiration. It would be best to know that Mucinex cold, flu, and sore throat medication does not work against chronic breathing problems such as lung cancer, asthma, or chronic emphysema.

Mucinex Side Effects

Mucinex's most common side effects may include nausea, vomiting, headache, stomach pain, and dizziness. Call your doctor right away if you have any of the serious side effects, such as:
• Severe headache that doesn't go away;
• Severe sore throat;
• Severe stomach ache;
• Severe dizziness or anxiety;
• Worsening of your cough

Mucinex Precautions

Before taking Mucinex medicine, inform your doctor if you are taking monoamine oxidase inhibitor (MAOI) (certain medications used to treat depression, psychosis, or Parkinson's disease) or if you recently stopped taking MAOIs. Mucinex is a tablet and should be taken orally with or without food. It is usually taken every 12 hours with a full glass of water. Your dose depends on the severity of your symptoms and response to treatment. Do not use more than four tablets in a day to prevent the risk of severe side effects. Swallow the tablets whole. Do not crush or chew the tablets. You may feel relieved of your symptoms a few hours after taking the medication. Discuss with your doctor if there is no improvement in your condition, especially if your cough lasts more than seven days, comes back, or occurs with fever, rash, or persistent headache.

Before you start using this medication, tell your doctor about your medical history, including history of breathing problems including emphysema, chronic bronchitis, asthma, smoker's cough, coughing out blood, liver problems, kidney disease, heart failure; think you may be pregnant or plan to become pregnant; are breastfeeding, or are planning to breastfeed. Tell your doctor about all your medications, including prescription, OTC, herbal supplements, and vitamins. There may be a drug interaction between Mucinex and other medications, such as selegiline, metoclopramide, isocarboxazid, and phenelzine. During pregnancy, it is unknown if Mucinex has a harmful effect on the unborn child. Discuss the risks and benefits of using Mucinex in pregnancy. Guaifenesin passes into breast milk and should be used with caution if breastfeeding a baby. Do not use Mucinex for children below the age of we. Store Mucinex tube cream at room temperature and keep it out of the reach of children.
