Groprinosin 50 Tablets 500 mg https://www.amazon.com/dp/B095P8R3T6/ref=cm_sw_r_cp_api_glt_i_589X8WHV52F5NZC9Y474
That is goprinosin which is the brand name in Eastern Europe. I ordered through this seller and it got here (middle America) in a week which was surprising. This seller and another also sell a different brand off Amazon. Before using, make sure you read the pamphlet. Best bet is the Imunovir pamphlet.

I took a different dose than what was recommended because i only got two boxes of 50. So far, so good. Thought i had a recurrence after the initial outbreak cleared but i think i was just being overly cautious. Still touched it up just in case.
(If you'd be interested in getting IP read this, if not no worries :))
Assuming this would work the same way in the UK that it does in Canada, to buy a certain form of IP (Immunovir, generic canadian form) I required an RX from my doctor, but for my second round I found a site which sold the Groprinosin (Polish Generic form) for a cheaper price, and didn't require an RX. I was able to ship the drug from Poland to Canada, the parcel spent more time in customs but ultimately came through.
Other forms which seem to be OTC (and available for international shipping) are Isoprinosine (Mexico Generic), Isoprinosine (Hungary Generic) etc.
You can check here for more generic versions: https://www.drugs.com/international/inosine-pranobex.html
or even purchase the generic form from amazon https://www.amazon.com/Groprinosin-50-Tablets-500-mg/dp/B095P8R3T6/ref=sr_1_2?keywords=groprinosin&qid=1652878054&sr=8-2
Sorry to bother, hope this might be helpful!
