Summary
Weight-loss injections such as liraglutide, tirzepatide and semaglutide, given under the skin to treat obesity, do not break the fast. The injection does not pass through an open cavity and contains no nutrients, only a hormone that signals fullness to the brain and helps control appetite. The ruling relies on contemporary scholars and the Islamic Fiqh Academy resolution that medical injections under the skin, into muscle or into a vein do not invalidate the fast. Taking it is permissible on the advice of a specialist.
Written in our own words from the original fatwa — check the source before acting on it.
Suntikan ubat kurus (liraglutide/tirzepatide/semaglutide) yang dicucuk di bawah kulit bagi tujuan rawatan obesiti adalah tidak membatalkan puasa.
