Does Amprolium Hydrochloride have any effect on human health?

Yes, it can cause adverse reactions such as contact dermatitis and asthma. Adverse reactions of anorexia or diarrhoea are rare and occur mainly with high doses and prolonged use. Thiamine deficiency can cause central nervous system (CNS) symptoms, but can be reversed with the addition of thiamine to the diet. However, thiamine supplementation may interfere with the efficacy of the drug.
