Hi, Thanks for using HCM.
Small itchy blisters
appears in palmer aspect only after drinking alcohol may be due to allergic response
. The allergen may be some additives in alcohol or some particular type of alcohol.
problem the itching will be all over the body so we can exclude it but for safer side get done LFT once.
This may be due to any drug interaction
also but usually interaction will be very severe. So if you are taking any drugs routinely or during alcohol, let us know to rule out if any interactions.
For now take anti histaminic and apply topical glycerine. Consult your doctor for further management.
Hope I answered your question. Feel free to ask me if you have any further queries.
Wish you good health. Take care.
