Dear @Nouseforaname ,Yes Zantac ( Ranitidine) has been used to reduce the Asian flush by slowing the breakdown of alcohol to acetaldehyde. However the loss of the Asian flush reaction, leads to one consuming excessive amount of alcohol, becoming more drunk, greater impairment of judgement and even death due to alcohol- induced poisoning. Zantac has also been recalled off the shelves as on September 13, 2019, the FDA announced that preliminary tests found low levels of N-nitrosodimethylamine (NDMA) in ranitidine. NDMA is a probable carcinogen and hence long term use of Zantac may cause cancer only after exposure to high doses over a long period of time. Therefore I will advise not to take zantac or other equivalent while drinking and to hydrate more before or while taking alcohol. Hope this helps.
