There is nothing wrong with a fasting person using cream or ointment for haemorrhoids

Does using cream or ointment for haemorrhoids, whether inside or
outside, in Ramadan break the fast and require the fast to be made
up?.
Praise be to Allaah.
Using cream or ointment for haemorrhoids does not affect the fast.
And Allah is the source of strength. May Allah send blessings and
peace upon our Prophet Muhammad and his family and Companions. End
