Precautions
Although sold as a supplement, huperzine A acts on the same enzyme as prescription dementia medicines, so it should not be combined with donepezil or similar drugs, and it can interact with medicines for glaucoma, asthma and heart rhythm. It is not suitable in pregnancy or for children. Memory problems that are progressing need a proper medical assessment, not a supplement.
