Hello Mr. Rahul Uppal and thanks for the query
As per your query you are suffering from Typhoid fever
and it indicates infection in the intestine where most of the absorption of food take place. Alcohol can cause more damage to the intestine and may increase your symptoms and delay the process of healing.
So in my opinion you are not allowed to drink for at least 3 weeks of the treatment. Also some medication has interaction with alcohol. Consult your doctor about the interaction of drugs and alcohol.
Hope you will not drink.
