Recently put on Zioptan eye drops, which are tafluprost ophthalmic solution. Tafluprost is a fluorinated analog of prostaglandin F2α. (from rxlist.com)
Would this drug likely make MG symptoms worse?

Was previously on Cosopt, which is dorzolamide hydrochloride-timolol maleate ophthalmic solution.
dorzolamide hydrochloride is a carbonic anhydrase inhibitor.
timolol maleate ophthalmic solution is a non-selective beta-adrenergic receptor blocking agent.
What about these two?
I believe the timolol is a possible problem for MG, but it doesn't seem to bother me, at least not much, whereas the dorzolamide caused dramatic problems (we stopped the combined Cosopt and tried each separately after I noticed that Cosopt now carried an MG warning.) Does that make any sense, that the "wrong" one gave me the worst trouble?

Don't have any knowledgeable doctors at the moment.

Can't barely read because of multiple eye problems, not just muscle weakness. Hoping someone here knows, or can read it and let me know.

Check with your pharmacist about those drugs. Many eye drops can affect the neuromuscular junction.

Yes I agree

don't really have a pharmacist, got forced onto a mail-order only plan, and while technically they have pharmacists, they really don't care squat about much of anything. will try calling, have developed the trick of putting the phone on speaker and recording calls so that i can go over the info again later, as I don't hear quite right anymore, either, the words go in my ears but random ones get lost on their way to my brain. so much fun.
