: HI.... WE JUST BOUGHT THE STACKER 2 AND WOULD LIKE Table 1.--Patterns of Signs and Symptoms Associated With Dietary Supplements Containing Ephedrine Alkaloids
----------------------------------------------------------------------------------------------------------------
Organ/system involved Clinical significance Signs and symptoms
----------------------------------------------------------------------------------------------------------------
Cardiovascular system................... Serious.................... Dysrhythmias, severe hypertension,
cardiac arrest, angina, myocardial
infarction, and stroke \1\
Less clinically significant Tachycardia, mild hypertension,
palpitations.
Nervous system.......................... Serious.................... Psychosis, suicidal, altered or loss of
consciousness (including disorientation
or confusion), and seizures.
Less clinically significant Anxiety, nervousness, tremor,
hyperactivity, insomnia, altered
behavior, memory changes.
Gastrointestinal (GI)................... Serious.................... Altered serum enzymes, hepatitis.
Less clinically significant GI distress (nausea, vomiting, diarrhea,
constipation).

Page 30679


Dermatologic............................ Serious.................... Exfoliative dermatitis.
Less clinically significant Nonspecific rashes.
General manifestations.................. ........................... Numbness, tingling, dizziness, fatigue,
lethargy, weakness.
----------------------------------------------------------------------------------------------------------------
\1\ For the purposes of this document, strokes (i.e., cerebrovascular accidents) are considered to be related to
the cardiovascular system, because predisposing or inciting factors include hypertension, dysrhythmias and
ischemia, although it is recognized that the consequences affect the central nervous system.

B. The Availability of Ephedrine Alkaloids

To determine the types of ephedrine alkaloid-containing dietary
supplements available in the marketplace, the agency has collected over
125 dietary supplement products labeled as containing a known source of
ephedrine alkaloids during the past 2 years (Refs. 1 and 2). These
products show that ephedrine alkaloid-containing-dietary supplements
are marketed in a variety of forms, including capsules, tablets,
powders, and liquids. The source of the ephedrine alkaloids in these
supplements vary from the raw botanical to powdered plant material and
concentrated extracts; however, most of the products contain
concentrated extracts. Although FDA is aware that some companies have
changed their labeling and formulation since the market review, this
review of the marketplace reflects the general contours of products
currently sold in the United States.
Ephedrine alkaloids are present in some products as a single
ingredient, but more commonly, they are combined with other
ingredients, including vitamins, minerals, amino acids, and other
botanicals (Refs. 1, 2, and 21). Most of the dietary supplements that
contain an ingredient source of the ephedrine alkaloids also contain
between 6 and 20 other ingredients. Some of these other ingredients
have known or suspected physiological and pharmacological activities
that have the potential for interacting with the ephedrine alkaloids so
as to increase their effects. For example, the majority of dietary
supplements containing ephedrine alkaloids also contain a source of
xanthine alkaloids (e.g., caffeine), another stimulant substance that
is known to increase the effects of ephedrine alkaloids (Refs. 7, 16,
22, and 23).
Because product labels do not usually provide information on
product composition (Ref. 24), and there are no data bases containing
such data, FDA laboratories analyzed the products collected to quantify
the levels of ephedrine alkaloids (Refs. 1, 2, 21, and 25). Results of
the analyses show that these products, taking into account the labeled
recommended serving instructions, are likely to provide intakes of
ephedrine alkaloids that range from below the detectible limits of
FDA's analytical method to 110 mg per serving (i.e., per single use)
(Refs. 1, 2, 21, 25, and 26). Most of the products, regardless of their
promoted use, had ephedrine alkaloid levels at or above 10 mg per
serving.
Many of the dietary supplement products that FDA collected were
promoted for uses such as weight loss, body building, increased energy,
increased mental concentration, increased sexual sensations, or
euphoria or as alternatives to illicit street drugs (Refs. 1, 2, and
25). The majority of the products collected also bore warning
statements on their labels (Refs. 1, 2, and 27). The warning statements
varied from general precautions, suggesting that the consumer check
with a health care professional before beginning any diet or exercise
program, to more specific warning statements. The more specific warning
statements contained several elements, including cautions that the
consumer not use the product if they have certain diseases or health
conditions or are using certain drugs, and to stop the use of the
product if they develop certain symptoms (Refs. 1, 2, 25, and 27).
