Narrow Therapeutic Index Drugs
Before using the Far Infrared Sauna (FIRS), please consider any narrow therapeutic index drugs you may be currently taking or have taken in the past. When the body undergoes a detoxification via FIRS therapy, the body may excrete chemicals that have been stored in the body fat, which can then enter the bloodstream. When those chemicals get into the bloodstream, they will have some level of therapeutic effect intended by that medication. In addition, these medications listed may adversely effect FIRS therapy or aggravate the intended action of the pharmaceutical for treating conditions for which it was prescribed.
Additional medications to consider include: diuretics, barbiturates and beta-blockers that may impair your body's natural heat loss mechanisms. Anticholinergics may inhibit sweating and predispose you to heat rash and slightly increase the risk of heat stroke. Some over-the-counter drugs, such as antihistamines, may increase the risk of heat stroke.
