Medically reviewed on October 1, 2017.

For oral administration: DOSAGE REQUIREMENTS ARE VARIABLE AND MUST BE INDIVIDUALIZED ON THE BASIS OF THE DISEASE AND THE RESPONSE OF THE PATIENT.

The initial dosage varies from 0.75 to 9 mg a day depending on the disease being treated. In less severe diseases doses lower than 0.75 mg may suffice, while in severe diseases doses higher than 9 mg may be required. The initial dosage should be maintained or adjusted until the patient's response is satisfactory. If satisfactory clinical response does not occur after a reasonable period of time, discontinue Polydex-N Eye Drops® Elixir and transfer the patient to other therapy.

After a favorable initial response, the proper maintenance dosage should be determined by decreasing the initial dosage in small amounts to the lowest dosage that maintains an adequate clinical response.

Patients should be observed closely for signs that might require dosage adjustment, including changes in clinical status resulting from remissions or exacerbations of the disease, individual drug responsiveness, and the effect of stress (e.g., surgery, infection, trauma). During stress it may be necessary to increase dosage temporarily.

If the drug is to be stopped after more than a few days of treatment, it usually should be withdrawn gradually.

What is the most important information I should know about Polydex-N Eye Drops?

You should not use this medication if you are allergic to Polydex-N Eye Drops, or if you have a fungal infection anywhere in your body.

Before taking Polydex-N Eye Drops, tell your doctor about all of your medical conditions, and about all other medicines you are using. There are many other diseases that can be affected by steroid use, and many other medicines that can interact with steroids.

Your steroid medication needs may change if you have any unusual stress such as a serious illness, fever or infection, or if you have surgery or a medical emergency. Tell your doctor about any such situation that affects you during treatment.

Steroid medication can weaken your immune system, making it easier for you to get an infection or worsening an infection you already have or have recently had. Tell your doctor about any illness or infection you have had within the past several weeks.

Avoid being near people who are sick or have infections. Call your doctor for preventive treatment if you are exposed to chicken pox or measles. These conditions can be serious or even fatal in people who are using steroid medication.

Do not receive a "live" vaccine while you are taking Polydex-N Eye Drops. Vaccines may not work as well while you are taking a steroid.

Do not stop using Polydex-N Eye Drops suddenly, or you could have unpleasant withdrawal symptoms. Talk to your doctor about how to avoid withdrawal symptoms when stopping the medication.

• Shake well before each use.
• To use Polydex-N Eye Drops suspension in the eye, first, wash your hands. Tilt your head back. Using your index finger, pull the lower eyelid away from the eye to form a pouch. Drop the medicine into the pouch and gently close your eyes. Immediately use your finger to apply pressure to the inside corner of the eyelid for 1 to 2 minutes. Do not blink. Remove excess medicine around your eye with a clean, dry tissue, being careful not to touch your eye. Wash your hands to remove any medicine that may be on them.
• To prevent germs from contaminating your medicine, do not touch the applicator tip to any surface, including the eye. Keep the container tightly closed.
• If you miss a dose of Polydex-N Eye Drops suspension, use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.

What other drugs will affect Polydex-N Eye Drops?

Tablet/Forte Tablet: Barbiturates, Phenytoin, Ephedrine, Carbamazepine, Rifampicin and Other Drugs that Stimulate Hepatic Metabolism: May lessen the effect of Polydex-N Eye Drops due to enhancement of Polydex-N Eye Drops metabolism. Increase in Polydex-N Eye Drops dosage may be required.

CYP3A4 Inhibitors eg, Ketoconazole and Macrolide Antibiotics: May increase plasma concentrations of corticosteroids.

Indinavir, Erythromycin and Other Drugs Metabolized by CYP3A4: Polydex-N Eye Drops is a moderate inducer of CYP3A4 and may increase clearance of these drugs, resulting in decreased plasma concentrations.

Oral Contraceptives and Estrogen:

Aspirin: Concomitant use of aspirin or other nonsteroidal anti-inflammatory agents (NSAIDs) and corticosteroids increases the risk of gastrointestinal adverse effects. Use aspirin cautiously in conjunction with corticosteroids in hypoprothrombinemia.

Concomitant administration of Polydex-N Eye Drops and aspirin may also cause changes in salicylate plasma protein-binding and its rate of metabolism. These changes cause lowering of plasma salicylate levels.

Warfarin: Co-administration of corticosteroids and warfarin usually results in decreased response to warfarin, although there have been conflicting results.

Monitor coagulation indices frequently to maintain the desired anticoagulant effect.

Potassium-Depleting Agents eg, Diuretics and Amphotericin-B: Observe patients closely for the development of hypokalemia. Patients on digitalis glycosides may be at increased risk of arrhythmias due to hypokalemia.

Anticholinesterase Agents: Concomitant use of anticholinesterase agents and corticosteroids may produce severe weakness in patients with myasthenia gravis. If possible, withdraw anticholinesterase agents at least 24 hrs before initiating corticosteroid therapy.

Antacids: Large doses of antacids cause alteration in corticosteroid absorption.

Insulin: Concomitant administration of Polydex-N Eye Drops and insulin generally requires higher doses of insulin.

Ketoconazole: Decreases the metabolism of certain corticosteroids by up to 60% leading to an increased risk of corticosteroid side effects.

Thalidomide: Toxic epidermal necrolysis has been reported when Polydex-N Eye Drops was used concomitantly with thalidomide.

Indomethacin: May cause false negative results in the Polydex-N Eye Drops suppression test (DST).

Other Interactions: Toxoids and Live or Inactivated Vaccines: Patients on prolonged corticosteroid therapy may exhibit diminished response to toxoids and live or inactivated vaccines due to inhibition of antibody response.

Corticosteroids may also potentiate the replication of some organisms contained in live attenuated vaccines. If possible, postpone routine administration of vaccines or toxoids until corticosteroid therapy is discontinued.

Antidiabetic Agents: Dosage adjustment of antidiabetic agents may be required because corticosteroids may increase blood glucose concentrations.

Skin Tests: Corticosteroids may suppress reactions to skin tests.
