Do Dorzolamide Eye Drops Come In A Preservative-Free Form?

Answer

Dorzolamide 2% eye drops, unfortunately, do not come in a preservative-free form. It is manufactured by several different companies, all of which add a preservative.

While the ingredients of all the different dorzolamide eye drops vary slightly, they all contain benzalkonium chloride, an antimicrobial preservative.

Alternative Options

Dorzolamide is a carbonic anhydrase inhibitor used for the treatment of glaucoma.

The only other carbonic anhydrase inhibitor product (that only contains one active ingredient) is Azopt (brinzolamide). That too is only available with preservatives.

Nevertheless, you do have some potential options to talk to your doctor about, which include:

• Cosopt PF (dorzolamide; timolol)
• Zioptan (tafluprost)
• Timoptic Ocudose (timolol)

All of these drugs are available in single use, preservative-free containers.

Cosopt PF (a preservative-free combination of dorzolamide and timolol) would be your most similar option since it already contains dorzolamide and adds on the beta-blocker timolol.

The other preservative free options are in different drug classes.

Timoptic Ocudose contains timolol as the sole drug and Zioptan is an ophthalmic prostaglandin.

There are many considerations to take into account when determining what the most appropriate course of therapy for an individual treating glaucoma is.

For most individuals, the recommended initial therapy is a prostaglandin, like Zioptan, because they have been shown to be effective at lowering intra-ocular pressure, are well tolerated, can be dosed once daily and have fewer side effects than other options.

If you are looking to use only a preservative-free option to treat your glaucoma, talk to your doctor about any of the options above.
