I presume you mean "paracetamol, sodium bicarbonate and caffeine." ?
If so, why not buy the ingredients separately.
I have had to do something similar when the licence for Syndol was rescinded. Although it is still available in South Africa and can be purchased for ten times it's original price.
The same goes for, of all things Euthymol toothpaste. Which has been withdrawn due an EU directive regarding an ingredient. Try buying another toothpaste that does not have fluoride added.
