Introduction An adverse drug interaction is defined as an interaction between one or more coadministered medications which leads to alteration of the effectiveness or toxicity of any of the coadministered medications. Drug interactions can be caused by P rescription and Over-the-counter (OTC) medications, herbal products or vitamins, foods, diseases, and genetics (family history). It is estimated that people over 65 take an average of seven drugs at any one time to treat a variety of illnesses including higher cholesterol, diabetes, hypertension, etc. With this amount of medicine use, the probability that a person will take two prescribed drugs that may interact with one another is very high.

Niacin & Statins:

Niacin & Statins If coadministration of Niacin and Statins is required, monitor the patient for signs and symptoms of myopathy or rhabdomyolysis (Muscle pain, Tenderness , or weakness ). Periodic creatine kinase (CK) determinations may be advisable . http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4110829 /

Conclusion The occurrence of significant morbidity and mortality can be reduced by minimizing the risk for drug interactions. The hyperlipidemic patients should bring a list of all the drugs they are taking including prescription drugs, over-the-counter drugs, and any supplements, herbal or otherwise, during their visit to the doctor or pharmacist . The risk of adverse effects could be reduced and the quality of life for patients improved by healthcare professionals through the screening , education, and follow up on suspected drug interactions. If possible, the hyperlipidemic patients are recommended to fill all their prescriptions at one pharmacy.
