Hemorrhoids Medication Prescription

is it haraam to use a medication/cream for a condition that contains haraam ingredients?
asalaam alaikum everyone.♥
so i have hemorrhoids and i bought the preparation H cream for it. i bought the regular one because mine isnt severe. its only mild. but after i bought it i checked the ingredients and it said that there was 3% shark liver oil (to protect the damaged tissue).
i dont know what to do now. im hesitant about this because i dont know of any other product that doesnt require a prescription that will help.
i checked online just now and there is one without the shark liver oil but its for extreme relief and i dont want to use that for a problem that isnt extreme, ya know? like it could be TOO strong.
i dont know what to do. please help.
thank you.♥
its also internal though.
Shark is a type of fish and as you know fishes do not require a dhabh (slaughtering in the name of Allah) to be consumed or utilized for other purposes. Therefore even if a fish is caught dead it is permissible to consume it or use it for other purposes. Therefore shark oil will be considered permissible to be consumed or applied externally in all the cases.

EDIT:
@Myotsimo please do not comment without proper knowledge. Do some research first. In Islam the criteria for classification of objects and animals is Urf and not philosophy or science. In urf shark is a fish thats all. It does not matter whether it has scales or not. Even whale is considered a fish even though scientifically it is a mammal Therefore it is the unanimous decision of the whole ummah that shark is permissible to be consumed.

@asker when it is permissible to consume it, it will be permissible to use it internally as well.
