Robitussin is one brand of medication containing dextromethorphan and guaifenesin as active ingredients. Many other brands are available, including Pediacare, Nycoff, Simply Cough and Vicks 44, but Robitussin is a brand many people are familiar with. Robitussin is sold over the counter without a prescription.
Variations
Many variations of Robitussin exist, with different amounts of the active ingredients. Some contain other ingredients that treat additional symptoms. One variant of Robitussin has guaifenesin only and does not have any dextromethorphan. Variants are distinguished by the letters behind the Robitussin name and by the active ingredients listed on the packaging. For example, Robitussin DM contains both dextromethorphan and guaifenesin and Robitussin Cough & Cold CF contains these two active ingredients plus pseudoephedrine. Robitussin is available in liquid and lozenge form.
Purpose
The guaifenesin in Robitussin acts as an expectorant, loosening chest congestion caused by colds or allergies. Dextromethorphan acts as a cough suppressant and directly affects the areas of the brain controlling coughing. The combination of these two active ingredients can help relieve the symptoms of many different types of respiratory illness including the common cold, flu, allergies or infections.
Usage
Dosage depends upon the age of the individual, the specific strength of the particular variation used and any individual physiological factors that might affect the use of this drug. Proper dosage can be determined by a doctor, and use of this medication should follow what the doctor recommends.
Side Effects
Most side effects to Robitussin are mild, such as nausea, dizziness, constipation, headache or a rash. Some people have an allergic reaction to Robitussin, which may invoke a severe reaction involving trouble breathing, hives or swelling in the face and throat. Others may overdose on this medication. These people will exhibit signs that may include blurred vision, slowed breathing, confusion, restlessness or irritability. Anyone showing symptoms of an overdose should be brought to the emergency room for care.
Warnings
According to the Partnership for a Drug Free America, some teens abuse Robitussin in an attempt to achieve a dissociative high by ingesting high levels of dextromethorphan. This medication may cause a chemical dependency in some individuals who use it, especially in those who abuse it, although this is rare. This medication also should not be given to children under the age of 4. Robitussin may interact with other medications, so using it in combination with other drugs should be discussed with a physician to avoid conflicts.
Considerations
According to KellyMom, a breastfeeding and parenting website, Robitussin and its two main ingredients, guaifenesin and dextromethorphan, are generally safe for breastfeeding mothers. The variant of Robitussin containing only guaifenesin and not dextromethorphan is sometimes used to help improve fertility, since this ingredient acts to thin out mucus in the body, including the cervical mucus of a woman's vaginal tract.
