One of the main uses for zinc acetate lozenges is to help people recover from a cold faster, notes the University of Maryland Medical Center. Zinc acetate is also used to help improve brain function in people who have hepatic encephalopathy.
As of 2015, several studies have shown that patients who have taken zinc acetate or gluconate lozenges during a cold saw symptoms, such as coughing, sore throat and runny nose, improve faster than those on a placebo, states University of Maryland Medical Center. Zinc acetate lozenges do not prevent a cold from occurring. Zinc acetate or other forms of zinc are also used to help treat conditions such as acne, Wilson's disease, bad breath and diaper rash, notes the United States National Institutes of Health's Medline Plus.
