Medicine sensitivity is common to people with multiple chemical sensitivity due to impaired liver detoxification, heightened nerve inflammation and sensitisations to the nervous system. For this reason a multi dimensional approach combining chemical exposure reduction and non pharmacological stress and symptom management strategies recommended to people with other Central Sensitivity Syndromes (CSS) such as fibromyalgia is often preferred.
For some people however, medications can be helpful and may even decrease sensitivities. Most useful seem to be Tricylic Antidepressants, Gabapentin (Neurontin) and Pregabalin (Lyrica). These generally need to be started on lower doses than usual and increased slowly under medical supervision. Following the same recommendations made by the Center for Disease Control and Prevention (CDC) in the MCS related condition Chronic Fatigue Syndrome
The Centre of Disease Control Says...
"Many CFS patients are sensitive to medications, particularly sedating medications. Therapeutic benefits can often be achieved at lower than normal dosages, so try prescribing a fraction of the usual recommended dose to start and gradually increase as necessary and as tolerated. All medications can cause side effects, which may lead to new symptoms or exacerbate existing symptoms, so it is important to routinely monitor all prescription drugs, OTC therapies and supplements the patient is taking." www.cdc.gov/cfs/cfstreatmentHCP.htm#pharmacologica
For people with more severe pharmacological food intolerance medicine sensitivity is generally increased particularly to aspirin, many anti-inflammatories, anti-depressants and others containing salicylates and phenols.
