It seems like cyclizine is indeed OTC here. It's pharmacy only, one of the ones that needs to be sold specifically by a qualified pharmacist once in there, rather than counter assistants. I checked, last week, when picking up my refill.
They have it on display on the shelves behind the counter, and I remembered seeing in another pharmacy that the other place, had a poster up about specific meds, to question people about if asked for before sale, and which had either been reduced from POM status to just P, and valoid was on there, along with the expected stuff like PSE, dextromethorphan, a fair few others.
So I went to the place I usually pick my meds up, to pick up a refill the other week and asked the pharmacist whether it was indeed P, rather than POM (I actually have a script for it, so it was a fact-finding expedition not actually of use to me personally. Got it scripted partly because an antihistamine is useful a lot of the time for opioid itching, but mostly because I've got some GI issues that sometimes make me really, REALLY sick. It's put me in hospital before, was originally given fexofenadine as the antihistamine, but it's pretty crappy IMO and I didn't even bother using it, since it didn't help much at all, so now it's cyclizine, with ondansetron, the latter on an as-needed rather than daily basis, works like fucking magic, when my guts play up, when the two are combined and plugged [because when things get really bad, at their worst, I can't swallow anything without it coming back up within 60s, unabsorbed, even a sip of water will trigger vomiting and retching, it sucks ass]
Explained that some other people had been saying it's POM (as I'm already scripted it, so the guy didn't think I was up to anything, as why, if already prescribed it would I be interested in getting loads more of the stuff..), and that poster I'd seen in another pharmacy, and he confirmed that it is P, not POM.
It might be one of those things that can be sold OTC, but most or many pharmacists have a stick up their arse about it, like codeine linctus, Gee's, etc.
Unbranded, 50mg tablets, can't remember if it was 50ct or 100ct, 100 I think, unless the pharmacist himself is mistaken, then it seems like they are OTC, just hard to get in many pharmacies.
