It is available in packs of 10 x 50g sachets of powder.

This is a prescription item and will be sent once a valid prescription is received.


If you see the "prescription required" sign next to an item you’d like to order, it means the item can only be issued with a prescription. While you can add these items to your shopping cart and pay for them along with other non-prescription products, we can’t dispatch them until we’ve received a prescription.
