Generic name: Ketorolac tromethamineBrand names: Acular

Why is Acular prescribed?

Acular relieves the itchy eyes brought on by seasonal allergies. Doctors also prescribe it to reduce inflammation after cataracts have been removed from the eyes. A preservative-free formulation (Acular PF) is used to reduce pain and light-sensitivity following operations to correct vision. Acular belongs to the class of medications called nonsteroidal anti-inflammatory drugs.

Most important fact about Acular

Acular sometimes causes an inflammation of the cornea (the clear tissue over the pupil of the eye). This can lead to a sight-threatening breakdown of the cornea. Warning signs may include sensitivity to light and a sensation like a foreign body in the eye. If you develop these problems, see your doctor immediately. Acular may have to be discontinued.

How should you take Acular?

Do not administer Acular while wearing contact lenses. If you are using Acular PF, open a new single-use vial for each dose and discard any unused contents after administering the drop. To prevent contamination and possible infections, avoid touching the eyedropper or single-use vial to the eye or any other surface.

  • If you miss a dose...Apply the forgotten dose as soon as you remember. However, if it is almost time for your next dose, skip the one you missed and return to your regular schedule. Do not apply two doses at once.
  • Storage instructions...Store at room temperature. Protect from light.

What side effects may occur?

Side effects cannot be anticipated. If any develop or change in intensity, tell your doctor as soon as possible. Only your doctor can determine if it is safe to continue using Acular.

  • Side effects may include:Temporary stinging and burning when the drops are applied.

Why should Acular not be prescribed?

If you've ever had an allergic reaction to the active ingredient ketorolac (found in the painkiller Toradol), you should not use Acular.

Special warnings about Acular

A history of reactions to other nonsteroidal anti-inflammatory drugs, including aspirin, makes a reaction to Acular more likely. Tell the doctor about any drug reactions you've experienced.

Drugs such as Acular may make the blood slower to clot, leading to increased bleeding after eye surgery. Use Acular with caution if you tend to bleed easily or are taking a blood thinning medication. Acular may also delay healing.

Problems in the cornea are more likely after complicated or repeated eye operations, or if you use Acular for more than 1 day prior to surgery or more than 14 days afterwards. The risk of such problems is also greater if you have diabetes, arthritis, dry eyes, or pre-existing corneal defects.

Acular is not recommended for children under 3 years of age.

Possible food and drug interactions when taking Acular

No interactions with Acular have been reported.

Special information if you are pregnant or breastfeeding

Avoid Acular late in pregnancy; the drug could have harmful effects on the developing baby. If you are pregnant or plan to become pregnant, inform your doctor immediately.

Use Acular with caution while nursing a baby.
