Robitussin Abuse Symptoms

Even though it is a drug that is indicated for the treatment and relief of coughs, Robitussin has the potential of causing tolerance, addiction, and dependence, even when taken as recommended by the doctor. The worst cases of addiction occur when the drug is taken in very high, unusual dosages, the main reason of abuse.

The two main active component of the drug are dextromethorphan and guinafenesin. Dextromethorphan is a cough suppressant that affects the brain signals that trigger the coughing reflex. Guinafenesin acts an expectorant and loosens phlegm, causing the expulsion of the sputum through the mouth. Because of the double effect, Robitussin is highly effective in the treatment and relief of chesty dry coughs that are caused by the common cold or upper respiratory tract infection.
