At home, doctor gets drink (6)
I believe the answer is:
ingest
'drink' is the definition.
(thesaurus)
'at home doctor gets' is the wordplay.
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'doctor' indicates an anagram.
'gets' anagrammed gives 'gest'.
'in'+'gest'='INGEST'
(Other definitions for ingest that I've seen before include "Swallow, absorb" , "Take (food) into the body" , "Swallow -signet (anag)" , "Absorb, assimilate" , "Absorb mentally" .)
