Ally, please see forum posts by forum user ICU for her/his extensive anti parasite protocols, used by numerous Curezone users.
The protocols mentions examples of which animal deworming protocols are suitable.
As Paul mentions, many (other) animal deworming products contain much too low concentrations of the active compounds to be able to be effective for human consumption. I have noticed this is true for many of the horsewormer Praziquantel products for example.
As you are in the UK/Europe, also do yourself the favour of looking into pharmaceuticals directed for human consumption and offered online, e.g. eurodrugstore.eu supply numerous "antihelminthics" (antiparasitic drugs).
