It is not recommended to take any cold medicine after drinking: firstly, cold medicine can easily produce allergic reaction with alcohol, and serious anaphylactic shock or even life-threatening can occur. Secondly, taking cold medicine after drinking is likely to increase the burden on the liver, because alcohol and drugs are metabolized by the liver, and taking cold medicine immediately after drinking can easily lead to more serious liver damage. So you can’t take cold medicine immediately after drinking, it is recommended to take cold medicine at least 24 hours after drinking, because this time a lot of alcohol in the body has been metabolized out, and then take cold medicine on the body basically will not cause any effect, and after taking cold medicine is recommended to drink alcohol after 5-7 days, safer.
