Lybrate-user, Thanks for the query. Thyroxine is taken early morning on emty stomach. Then nothing should be taken after that for at least 1 to 1 and half hour. Albendazole is to be taken at night, plus usually it is just one tablet or at times may be repeated after a fortnight. There is absolutely no problem in taking that if needed. Thanks.
