Advice please

I am British but I live in Southern Spain. I am on private healthcare as I am retired but not pension age. So, I have been seeing an Opthalmologist in a private hospital who speaks fairly good English.

I had an eye test in July and had high pressure so saw the Ophthalmologist on the 2nd August. He told me I had glaucoma and prescribed Fixaprost drops. A week later I had further tests, and it was ascertained that I had no optic nerve damage, but I was told I had to use the drops forever.

A fee weeks later I started feeling unwell. I wear a Fitbit and it was registering my heart rate was much lower than normal (it's already quite low, as is my blood pressure) and I was also getting dizzy spells and passed out a few times and I had shortness of breath. I got an appointment to see the Opthalmologist straight away when I told the clinic my symptoms and he immediately took me off the drops which apparently have a beta blocker in. So he prescribed Monoprost.

I have been taking these now for about 6 weeks and although I am not getting the other symptoms, I am still getting dizzy spells and they ate affecting my day to day life.

The ophthalmologist I am seeing only works in our local clinic one day a week and I can't go anywhere else because my insurance will only pay at certain clinics. He told me he wanted to see me in December but I am concerned that maybe I should see him sooner. However, I don't know if I am just wasting my time and his as dizziness is listed as a side effect. Do I really have to put up with this forever?

We have no support groups here and the ones I found on FB seem to be based in the US and things are very different there. Everyone seems to have surgery.

I have read that there are different types but he didn't tell me which. he haant taken my blood pressure or anythubg and I would rather not take this medication if it makes me feel like this.

Does anyone have any advice please?
