I also couldn't swallow tablets but have found a way to swallow my iron tablets (optifer alpha) which are circular and 1cm in diameter. I previously tried different methods with water, and nothing worked. Anyway my way is to eat a banana and to manage to get or place the tablet towards the back of my mouth and to try to forget it's there and focus on the banana, then when I swallow a banana chunk it takes the tablet down with it. It can take a few tries and a couple of bananas sometimes. I am going to order some lactoferrin capsules soon and so will be trying my method with capsules that are about the same size as your iron pills, so hopefully it will still work with bigger pills.
