Sterilid-V (sulfacetamide + prednisolone eye drops)

Written by Stephanie Nera, RPh, PharmD · Pharmacology

Updated Jun 23, 2021

Sterilid-V is a combination preparation of two drugs: sulfacetamide sodium and prednisolone acetate. It is used to treat eye conditions that require preventing infection as well as inflammation and redness. It is available as an ophthalmic suspension in the form of eye drops.

Sulfacetamide sodium is a sulfonamide antibacterial agent. It is bacteriostatic, which means it prevents the growth of bacteria but does not necessarily kill bacteria upon exposure.

Prednisolone is a corticosteroid. Corticosteroids, or steroids, are synthetic drugs that are modeled after the naturally occurring hormone cortisol, which is produced in the adrenal glands. Corticosteroids reduce inflammation, pain, itchiness, and other effects mediated by the immune system response.



What is Sterilid-V used for?

Sterilid-V is mainly indicated to treat the symptoms of the following conditions:

  • Palpebral and bulbar conjunctiva
  • Allergic conjunctivitis
  • Superficial punctate keratitis
  • Trachoma

How should I take Sterilid-V?

As an ophthalmic suspension, carefully instill the drops onto the eye. Do not touch the tip of the dropper with your finger or eye. Cover the tip with the lid immediately after using it.

How do I store Sterilid-V?

This product is best stored at controlled room temperature away from direct light and moisture. To prevent drug damage, you should not store it in the bathroom or the freezer. 

There may be different brands of this drug that may have different storage needs. So, it is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.

You should not flush this product down the toilet or pour them into a drain unless instructed to do so. Additionally, it is important to properly discard this product when it is expired or no longer needed. Consult your pharmacist for more details about how to safely discard your product.

Precautions & warnings

What should I know before using Sterilid-V?

Corticosteroids, including Sterilid-V, are associated with an increased risk of infection, bone demineralization, weight gain, water retention, and various other effects. This risk is further increased in elderly patients, young patients, immunocompromised patients, and those undergoing chronic treatment with steroids.

Never stop taking corticosteroids suddenly. If side effects are being experienced or you have completed your therapy, your doses must be tapered gradually until it is safe to stop taking corticosteroids. Abruptly stopping the use of steroids can result in adrenal insufficiency, which is potentially life-threatening.

Some groups of people with conditions like osteoporosis, diabetes mellitus, hypertension, hypothyroidism, myopathy, glaucoma, and myasthenia gravis may experience an exacerbation of symptoms after using corticosteroids.
