Neosporin-H Ointment 5 gm belongs to the class of 'antibiotics' and is primarily used to treat bacterial infections of the external eye and uveitis (inflammation of the middle layer of the eye (uvea)). Bacterial infection occurs when harmful bacteria grow in the body and cause illness. Neosporin-H Ointment 5 gm will not work for infections caused by fungi and viruses.

Neosporin-H Ointment 5 gm is composed of four medicines: Bacitracin, Hydrocortisone, Neomycin, and Polymyxin B. Bacitracin is a bacteriostatic medicine (stops the growth or reproduction of bacteria). It works by inhibiting bacterial cell wall synthesis. Hydrocortisone belongs to the class of corticosteroids. It blocks the production of prostaglandins (chemical messengers) that make the affected area red, swollen and itchy. On the other hand, Neomycin is an aminoglycoside antibiotic and prevents the synthesis of essential proteins required by bacteria to carry out vital functions. Polymyxin B, an antibiotic, destroys the bacterial membranes by binding to the phospholipids on the cell membranes of gram-negative bacteria. This process of binding causes the loss of essential metabolites in bacteria.

Your doctor will advise the appropriate dose that suits your infection. Common side effects of Neosporin-H Ointment 5 gm include itching, redness, dryness, and eye irritation. These side effects may not occur in every patient using this medication and differ individually. If the side effects persist longer or worsen, please seek a doctor's advice.

Neosporin-H Ointment 5 gm treats bacterial eye infections. It comprises four medicines, namely Bacitracin, Hydrocortisone, Neomycin, and Polymyxin B. Bacitracin is a bacteriostatic medicine (stops the growth or reproduction of bacteria) and works by inhibiting the bacterial cell wall synthesis. Bacitracin is active against many gram-positive and some gram-negative bacteria. Hydrocortisone is a corticosteroid and blocks prostaglandins' production (chemical messengers) that make the affected area red, swollen and itchy. Neomycin is an aminoglycoside antibiotic and prevents the synthesis of essential proteins required by bacteria to carry out vital functions. Polymyxin B, an antibiotic, destroys the bacterial membranes by binding to the phospholipids on cell membranes of gram-negative bacteria. This process of binding causes the loss of essential metabolites in bacteria. It is bactericidal against most gram-negative bacteria and has no in-vitro activity against gram-positive bacteria.

Bacterial eye infection: A bacterial eye infection occurs when bacteria invade any part of the eyeball or its surrounding tissues, including the cornea (clear front surface of the eye) and the conjunctiva (thin membrane lining the outer eye and inner eyelids). A bacterial eye infection symptoms include red eyes, pain, swelling of the eyes, watery eyes, itching, and blurry vision. Some very common eye infections are conjunctivitis (the inflammation and irritation of the eye's mucous membrane (conjunctiva), stye (bump on the eyelid), uveitis inflammation of the uvea (middle layer of the eye), marginal keratitis (inflammation of the cornea), and blepharitis (inflammation of the eyelids).
