I strongly recommend against putting essential prescription medications in checked baggage. You just never know if your bags might be delayed.

Actually, the page you linked seems to be very clear:


Any containers larger than 100ml (excluding essential medicines, see section below) will NOT be allowed through the security search point.


Essential medicines for the period of the trip may be permitted in larger quantities above the 100ml limit, but will be subject to authentication. Passengers must have obtained the prior agreement of the airline with which they are travelling and their departure airport. Passengers must also bring with them supporting documentation from a relevant qualified medical professional.


SO....I would highly recommend carrying the prescription creams with you. Simply declare them to the security officer and show a copy of the prescription (or the pharmacy label with the patient's name), etc.
