Side effects of Dextromethorphan in details

infoA side effect of any drug can be defined as the unwanted or undesired effect produced by the drug. The side effect can be major or in few medications minor that can be ignored. Side effects not only vary from drug to drug, but it also depends on the dose of the drug, the individual sensitivity of the person, brand or company which manufactures it. If side effects overweigh the actual effect of the medicine, it may be difficult to convince the patient to take the drug. Few patients get specific side effects to specific drugs; in that case, a doctor replaces the drug with another. If you feel any side effect and it troubles you, do not forget to share with your healthcare practitioner.
