Warning
Health Canada warns Canadians not to use "Thermonex"
OTTAWA - Health Canada is warning consumers not to use Thermonex
capsules, which are being advertised for weight loss, water loss and to
help boost thyroid output. This product could cause serious adverse
effects, including death.
Thermonex contains synephrine, which is similar to ephedrine and
may have similar adverse effects such as hypertension and cardiovascular
toxicity. These adverse effects could lead to stroke, heart attack and/or
death. Health Canada has previously advised consumers against the use of
ephedrine-containing products, especially those containing caffeine and
other stimulants*. Thermonex also contains high levels of the stimulant
caffeine and other ingredients which increase the effects of synephrine.
Many other health products advertised for weight loss, and containing
"bitter orange extract" may also contain synephrine.
Thermonex is manufactured by BSN Inc. in the U.S. While it is not yet
known if this product is currently being sold in Canada, shipments of
Thermonex have been refused at the Canadian border. Health Canada has
issued a Customs Alert to prevent shipments of this product from entering
the country. Should Health Canada become aware of this product being sold
in Canada, appropriate action will be taken to ensure its removal from the
market. Health Canada asks that [Canadian] consumers report retail outlets that carry
this product by calling 1-800-267-9675.
If consumers have concerns about Thermonex or similar products that
contain synephrine, especially those containing caffeine and other
stimulants, they should consult a pharmacist or physician.
Health Canada advises consumers, particularly those with pre-existing
conditions such as heart disease, hypertension, thyroid disease, diabetes,
enlarged prostate, anxiety and restlessness, glaucoma and pheochromocytoma
(a type of adrenal gland tumour), to consult a physician prior to the use
of any product marketed for weight loss, body building and increased
energy.
