is non toxic. Huperzine A is not known to be toxic even when
administered at 50 to 100 times the human therapeutic dose.
Approximately 10,000 people have been treated with the drug with no
evidence of toxicity.
Huperzine
A should be avoided by children, pregnant women and nursing mothers.
Because
of possible adverse effects in those with seizure disorders, cardiac
arrhythmias and asthma, those with these disorders should avoid
Huperzine A. Those with irritable bowel disease, inflammatory bowel
disease and malabsorption syndromes should avoid Huperzine A.
Because
Huperzine A may increase the likelihood of seizures for individuals
with epilepsy, it should not be taken by individuals who have or have
had seizures.
Huperzine
A may cause the heart to beat slower than it would normally.
Individuals who have heart rhythm abnormalities should avoid taking
Huperzine A due to the chance it may cause dangerous disruptions in
heart rhythm.
A side effect of increased
acetylcholine activity is an increase in body secretions, including
mucus and saliva. This effect may worsen respiratory conditions such
as asthma, bronchitis, and emphysema. Individuals with chronic
respiratory conditions should not take Huperzine A.
Increased
production of stomach acid, possibly caused by huperzine A's
cholinergic effect, may aggravate ulcers of the stomach or small
intestine. Therefore, individuals with ulcers should avoid taking
huperzine A.
Urine output may also be increased by
Huperzine A. Individuals who have bladder conditions or other
conditions, such as benign prostate hyperplasia (BPH), that may be
made worse by increased amounts of urine should not take Huperzine A.
