Medicine sensitivities or drug intolerance/sensitivity refers to an inability to tolerate the medication including any side effects when given at therapeutic or subtherapeutic doses.
A drug allergy is a form of drug intolerance that involves an immune-mediated component, and may cause anaphylactic shock.
Drug intolerance should not to be confused with drug tolerance (drug resistance) which refers to a lack of adverse effects even at higher than average doses. Some instances of drug intolerance are known to result from genetic variations in drug metabolism.[citation needed]
New medication intolerance is a common problem for ME/CFS patients, with some patients developing allergic reactions.[1]
Symptom recognition[edit | edit source]
- The International Consensus Criteria lists sensitivities to food, medications, odors or chemicals as an optional criteria for diagnosis, under the section C. Immune, gastro-intestinal and genitourinary Impairments.[2]
- 2018, The Centers for Disease Control and Prevention (CDC) website ME/CFS page Monitoring the Use of All Medicines and Supplements[3] gives guidance for healthcare providers on medications for ME/CFS patients.
Many patients with ME/CFS are sensitive to medications. This is particularly true of any medication that acts on the central nervous system, such as sedating medications: therapeutic benefits can often be achieved at lower-than-standard doses. Patients with ME/CFS might tolerate or need only a fraction of the usual recommended doses for medications. After initial management with lower dosing, one or more gradual increases may be considered as necessary and as tolerated by the patient.[3]
Prevalence[edit | edit source]
- In a 2001 Belgian study, 48.5% of patients meeting the Fukuda criteria and 54.8% of patients meeting the Holmes criteria, in a cohort of 2073 CFS patients, reported new sensitivities to food or drugs.[1]
