Trusopt (dorzolamide) is a carbonic anhydrase inhibitor that reduces the amount of fluid in the eye, which decreases pressure inside the eye, used to treat open-angle glaucoma and other causes of high pressure inside the eye. Trusopt is available in generic form. Common side effects of Trusopt include:

  • temporary blurred vision,
  • temporary burning/stinging/itching/redness of the eye,
  • watery eyes,
  • dry eyes,
  • sensitivity of eyes to light,
  • bitter or unusual taste in your mouth,
  • headache,
  • weakness,
  • tired feeling,
  • nausea,
  • dry mouth, or
  • sore throat.

Tell your doctor if you have rare but very serious side effects of Trusopt including:

  • vision changes,
  • signs of a kidney stone (e.g., pain in the back/side/abdomen, nausea, vomiting, blood in the urine),
  • yellowing eyes or skin,
  • dark urine,
  • unusual tiredness or weakness,
  • easy bruising or bleeding, or
  • signs of infection (e.g., fever, chills, persistent sore throat).

The dose of Trusopt is one drop in the affected eye(s) three times daily. Trusopt may be used at the same time as other topical ophthalmic drug products to lower intraocular pressure. If more than one topical ophthalmic drug is being used, the drugs should be administered at least ten minutes apart. Trusopt may interact with acetazolamide, dichlorphenamide, or methazolamide. Other drugs may interact with Trusopt ophthalmic. Tell your doctor all prescription and over-the-counter medications you use. Trusopt should be used only when prescribed during pregnancy. It is unknown if this drug passes into breast milk. Consult your doctor before breastfeeding.

Trusopt Consumer Information

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Although the risk of serious side effects is low when dorzolamide is used in the eyes, you should be aware of side effects that can occur if the medication is absorbed into your bloodstream.

Stop using dorzolamide ophthalmic and call your doctor at once if you have a serious side effect such as:

  • swelling or redness of your eyelids;
  • eye redness, pain, discomfort, or sensitivity to light;
  • drainage, crusting, or oozing of your eyes or eyelids;
  • severe skin reaction: fever, sore throat, swelling in your face or tongue, burning in your eyes, skin pain, followed by a red or purple skin rash that spreads (especially in the face or upper body) and causes blistering and peeling; or
  • stomach pain, loss of appetite, dark urine, jaundice (yellowing of the skin or eyes).

Less serious side effects may include:

  • burning or stinging in your eye;
  • bitter or unusual taste in your mouth;
  • blurred vision;

SIDE EFFECTS

Clinical Studies Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Controlled clinical trials

The most frequent adverse reactions associated with TRUSOPT were ocular burning, stinging, or discomfort immediately following ocular administration (approximately one-third of patients). Approximately one-quarter of patients noted a bitter taste following administration. Superficial punctate keratitis occurred in 10 to 15% of patients and signs and symptoms of ocular allergic reaction in approximately 10%. Reactions occurring in approximately 1 to 5% of patients were conjunctivitis and lid reactions [see WARNINGS AND PRECAUTIONS], blurred vision, eye redness, tearing, dryness, and photophobia. Other ocular reactions and systemic reactions were reported infrequently, including headache, nausea, asthenia/fatigue; and, rarely, skin rashes, urolithiasis, and iridocyclitis.

In a 3-month, double-masked, active-treatment-controlled, multicenter study in pediatric patients, the adverse reactions profile of TRUSOPT was comparable to that seen in adult patients.

Post-Marketing Experience

The following adverse reactions have been identified during post-approval use of TRUSOPT. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: signs and symptoms of systemic allergic reactions including angioedema, bronchospasm, pruritus, and urticaria; Stevens-Johnson syndrome and toxic epidermal necrolysis; dizziness, paresthesia; ocular pain, transient myopia, choroidal detachment following filtration surgery, eyelid crusting; dyspnea; contact dermatitis, epistaxis, dry mouth and throat irritation.
