Mucinex is an over the counter anti-congestant which is used to help relieve respiratory infections.
Mucinex is used to help control the symptoms of chest congestion so that your body can clear the infection from your body. This type of medication is known as an expectorant, which thins the mucus so that it is easier for your body to push it out of your airways.

If you are using the liquid form of Mucinex, use the measuring cup which came with your dose to ensure proper dosing. You can ask your pharmacist for a replacement if your dose did not come with a measuring cup. Avoid using more than one over the counter cold product at the same time as this could lead to an overdose. Because Mucinex has such a variety of preparations, you should take care to read all of the instructions so ensure that you are taking the proper dose, especially when giving this medication to children.
Most forms of Mucinex are available over the counter. Because you will be taking this medication without supervision it is important to take care to monitor your use and take the medication the way it has been directed. Make note of any contact information on the package that you can call to ask questions about dosing or safety information. If you are considering giving Mucinex to a child, talk with your doctor about the potential risk for side effects that could occur.
Adults may take 200-400 mg every four hours in varying forms of Mucinex. Doses should not exceed 2400 mg in a 24 hour period. Children ages 12 and older may be able to take a full adult dose of the liquid form. Use of tablets should be based on whether or not the child is able to swallow pills effectively. Children ages 6 to 12 may take 100-200 mg every four hours and should not consume more than 1200 mg in a 24 hour period. Those ages 2-6 may take 5-100 mg every four hours, not exceeding 600 mg in a 24 hour period.

Those with phenylketonuria should not use the dissolving granules of Mucinex. These contain aspartame which could make your condition worse. Ask your pharmacist about alternative forms of this medication which may be more appropriate for you.
Pregnant women or those who are breastfeeding should not use Mucinex as it can cause harm to your child. Mucinex has been rated in pregnancy category C. This means that laboratory tests have shown negative reactions by the fetus, but no testing has been done on human subjects yet. However, children under the age of 4 are at an increased risk to develop side effects, which could impact a breastfeeding infant. Talk to your doctor about these risks and determine whether or not the benefits of this medication outweigh these potential risks.
