What is Dorzox Eye Drop?

Dorzox Eye Drop is manufactured by Cipla and contains Dorzolamide HCl 2% as a sterile ophthalmic clear solution. It is a topical carbonic anhydrase inhibitor used to lower IOP in glaucoma. Dorzolamide is a clear solution. Some patients report a transient bitter taste from drainage into the throat, and mild stinging from the acidic pH (pH 5.6).

Hoe het werkt

Dorzolamide HCl blocks carbonic anhydrase isoenzyme II in the ciliary epithelium, slowing the formation of bicarbonate and the consequent flow of sodium and water into the posterior chamber. The result is reduced aqueous humour production and lower IOP. Topical CAIs reach significant intraocular concentration without the systemic side effects of oral acetazolamide (paraesthesia, kidney stones, taste disturbance).

Indicaties & Dosering

IndicatieDosering
Monotherapy1 drop in affected eye(s) three times daily
Add-on to a beta-blocker or PGA1 drop twice daily
If suspensionNot applicable — dorzolamide is a clear solution
Multiple dropsWait 5 minutes between different products

Bijwerkingen

Lokaal: blurred vision (less common), stinging on instillation (common, especially with dorzolamide), bitter taste in mouth (drainage through nasolacrimal duct), conjunctival hyperaemia, ocular pruritus, eyelid reactions.

Systemisch: headache, fatigue (rare), kidney stones (very rare with topical use, in contrast to oral acetazolamide).

Sulfa cross-reactivity warning. Both brinzolamide and dorzolamide are sulfonamide derivatives. Patients with severe sulfa drug allergy (Stevens-Johnson, anaphylaxis to sulfamethoxazole) have rarely developed cross-reactions. A history of mild sulfa rash is not an absolute contraindication, but discuss with your prescriber. Most reactions are mild conjunctival irritation rather than systemic hypersensitivity.

Waarschuwingen & Contra-indicaties

  • Ernstige sulfonamide-overgevoeligheid
  • Severe renal impairment (CrCl < 30 mL/min) — accumulation possible
  • Ernstige leverfunctiestoornis
  • Concurrent oral CAIs (acetazolamide, methazolamide) — additive but limited extra benefit
  • Corneal endothelial dysfunction (Fuchs dystrophy, post-corneal-graft) — CAIs may worsen corneal oedema
  • Pregnancy Category C — avoid unless benefit outweighs risk

Opslag

Store at 15–25°C. Discard 28 days after first opening. Keep tightly capped between uses.

Veelgestelde vragen

What is the difference between Dorzolamide HCl and acetazolamide?

Both target the same enzyme. Topical Dorzolamide HCl delivers therapeutic levels at the eye with minimal systemic exposure. Oral acetazolamide produces systemic side effects (paraesthesia, taste changes, kidney stones, metabolic acidosis) that often limit long-term use.

Can I use Dorzox Eye Drop if I'm allergic to sulfa antibiotics?

If you had Stevens-Johnson syndrome or anaphylaxis to a sulfonamide, avoid topical CAIs. Mild rash with sulfamethoxazole is not an absolute contraindication, but discuss with your ophthalmologist before starting.

Why does Dorzox Eye Drop make my mouth taste bitter?

After instillation, the drop drains through the nasolacrimal duct into the throat. Dorzolamide has a recognisable bitter taste. Punctal occlusion (pressing the inner corner of your eye for 1–2 minutes) reduces the effect.

How quickly does Dorzox Eye Drop work?

IOP reduction begins within 1 hour of the first dose; steady-state effect at 1–2 weeks. Average reduction is 18–22% from baseline as monotherapy.

Is the blurred vision after instilling Dorzox Eye Drop normal?

Mild transient blur lasting a few minutes is common as the drop spreads across the cornea. If blur persists beyond 10–15 minutes, contact your eye-care professional.

Can I combine Dorzox Eye Drop with other glaucoma drops?

Yes — CAIs are additive with beta-blockers, prostaglandin analogs, and alpha-2 agonists. Wait 5 minutes between different bottles. Fixed combinations such as dorzolamide+timolol exist for adherence.

Wat als ik een dosis vergeet?

Take it as soon as you remember unless the next scheduled dose is close — then skip the missed one. Do not double up.

Can I use Dorzox Eye Drop in pregnancy?

Category C. Topical CAIs cross the placenta in small amounts. Avoid unless your ophthalmologist judges the benefit clearly outweighs the risk. Discuss alternatives such as brimonidine or selective laser trabeculoplasty.

Why three times a day instead of twice?

When used as monotherapy, Dorzolamide HCl has an 8-hour duration so three-times-daily dosing maintains 24-hour IOP control. When added to an existing beta-blocker or prostaglandin, twice daily is sufficient because the partner drug provides additional coverage.

What if my eye becomes red or itchy?

Mild conjunctival redness is common in the first 1–2 weeks and usually settles. Persistent redness, swollen lids, or itching may indicate a hypersensitivity reaction — stop the drop and contact your ophthalmologist.
