Medical Forum / General / Vision / July 2007Dry Eye Restasis and Opcon A
I am on Restasis, lubricants and heat for dry eye, but my eyes are still fairly irritated. I tried some Opcon A in addition to the Restasis and lubricants and it really helps minimize the irritation. I used it about an hour after taking Restasis. Anyone know if there is a problem with taking Opcon A with all the other dry eye meds? Twice a day ought to be enough. > I am on Restasis, lubricants and heat for dry eye, but my eyes are > still fairly irritated.

Twice a day ought to be enough. conventional wisdom is that Opcon A is contraindicated in dry eye patients. Opcon A contains a vasoconstrictor and an antihistamine (which has anticholinergic side effects). Both of those agents can reduce tear secretion in the eye. In fact it's use is for people suffering from allergic symptoms which includes watery weeping eyes-- it is supposed to dry-up the tearing and reduce itching (another allergic symptom). Are you suffering from eye irritation after applying Restasis? If so, then perhaps the Opcon A reduces your inflammatory response to the Restasis making you feel more comfortable despite the fact that tear production has not been increased (and perhaps even been decreased). This is all conjecture on my part, and I am unaware of any data on the topic. >> I am on Restasis, lubricants and heat for dry eye, but my eyes are >> still fairly irritated.

AND it's preserved with Benzalkonium Chloride -- virtual Drano for the eyes. IF you have ocular allergy, ask your doctor to prescribe Acular PF -- the preservative-free version. Stay away from ocular preservatives. They're horrible for dry eye. Refrigerate your Restasis. Some people say that helps a lot.

Hi Neil, I was wondering when you said about ocular preservatives. Please could you explain a little about them? What sort of substances are they? Where could I find them or buy them? And also, what is meant by 'Virtual Drano'? TIA On Jul 25, 4:46 am, Kisame Hoshigaki <absolutelyinvinci...@hotmail.com> wrote: > Hi Neil, > > I was wondering when you said about ocular preservatives.

Best response I have seen. Congrats, Neil! >> I am on Restasis, lubricants and heat for dry eye, but my eyes are >> still fairly irritated.

I suspected that there might be a problem, but was unable to locate anything with a warning about the use of Opcon A when there is a dry eye diagnosis. Fortunately I took it only once. My eye doctor gave me a bunch of different lubricants to try out. The best of the lot, for me, are Soothe, Optive, and TheraTears. I don't think any of them contain the preservative benzalkonium chloride. Actually, the inactive ingredients in Restasis are fairly soothing...have to look for an eye drop with castor oil, glycerin and polysorbate. > >> I am on Restasis, lubricants and heat for dry eye, but my eyes are > >> still fairly irritated.

Also consider Refresh Plus and Systane. >> >> I am on Restasis, lubricants and heat for dry eye, but my eyes are >> >> still fairly irritated.

Actually I think I am getting best results by switching lubricants. I use Optive until it no longer stops the irritation, then switch to Soothe and then to TheraTears (5 minute flood). Systane and HypoTears don't seem to work as well. Lots of fun! > THANK YOU.

It isn't "dangerous" it's just counterproductive. > Actually, the inactive ingredients in Restasis are fairly > soothing...have to look for an eye drop with castor oil, glycerin and > polysorbate. Those ingredients (the "vehicle") in Restasis are the same as a dry-eye formula called Refresh Endura. -MT |
