Robitussin DM comes in a liquid form that you take by mouth. Dextromethorphan is an antitussive drug used to help relieve constant coughing. It helps stop your cough by decreasing activity in your brain that triggers your impulse to cough. Guaifenesin belongs to a class of drugs called expectorants. These drugs help loosen up and thin phlegm mucus in your throat and lungs so that your coughs are more productive. A productive cough will help bring up mucus that is causing chest congestion.
This clears your airways, making it easier for you to breathe. Each active ingredient in Robitussin DM causes different side effects. These side effects can be more mild. However, some can be serious. Side effects are usually not too common when you use Robitussin DM as recommended, but nausea is more common than the others.
Taking Robitussin DM with food or milk may help ease nausea, vomiting, and upset stomach. If you have side effects and they become bothersome, stop taking Robitussin DM and ask your doctor or pharmacist to recommend another product.
These side effects are usually rare. Only mild side effects are associated with guaifenesin. There are no serious side effects associated with it. A rash may be a serious side effect of dextromethorphan.

Delsym and Robitussin do not contain an expectorant, a medication intended to break up phlegm and mucus to allow them to clear the airways. If your cough contains an excessive amount of these substances, you should consult your healthcare provider. An expectorant, such as Mucinex guaifenesin , or other medications may be warranted. Dextromethorphan has been linked to fatal overdoses in children. The FDA recommends that dextromethorphan, along with many other common cold remedies, not be used in children under the age of six.
There are no well-controlled studies establishing safety in pregnant women, which has led the FDA to classify Delsym and Robitussin as pregnancy category C. While there may be limited transfer into breast milk, it is generally considered safe to take dextromethorphan while breastfeeding.
The use of dextromethorphan products at high doses to potentiate the effects of opiate-containing drugs is a cause for concern. This may be particularly true in young adults. Delsym is an over-the-counter cough suppressant medication that contains a long-acting formulation of dextromethorphan.
Delsym is for use in the temporary relief of cough and works in the part of the central nervous system known as the medulla to stop the cough reflex. It is available in grape and orange flavors in both a 3 oz.
Robitussin is also an over-the-counter cough suppressant medication that contains a long-acting formulation of dextromethorphan. Robitussin is for use in the temporary relief of cough, and like Delysm works in the part of the central nervous system known as the medulla to stop the cough reflex.
It is also available in grape and orange flavors in 3 and 5 oz. Both Delsym and Robitussin belong to a family of other cough and cold products which utilize the same leading trade name but differ in ingredients.
Delsym and Robitussin are both effective at suppressing temporary cough caused by acute processes such as the common cold. They are preferred over codeine-based prescription formulations because they are non-opioid and available without a prescription. Dextromethorphan products have been shown to be superior to other OTC products such as expectorants, decongestants, and antihistamines in controlling cough.
Delsym and Robitussin are considered pregnancy category C by the FDA, meaning there is not enough evidence to establish safety for use in pregnant women. Pregnant women should seek the advice of their healthcare professional and should only use these products when the benefit clearly outweighs the risk.
Delsym and Robitussin are both alcohol-free formulations. However, due to their potential to cause confusion, drowsiness, and other nervous system side effects which could be potentiated by alcohol, their concurrent use with alcohol should be avoided.
