Neparin is an eye medication. It is a pain-relieving medicine used to treat pain and inflammation associated with postoperative eye pain/cataract surgery. The standard or generic name for neparin is nepafenac. The uses, side effects, contraindications, and many more will be discussed in detail in this article.


This drug is for external use only. It is used in the relief of post-operative high pain and inflammation. First, you apply pressure on the corner of the eye, close to the nose. For about one minute immediately, after instilling the drop, wait for at least five to ten (5-10) minutes before delivering the following medication in the same eye to avoid dilution. You may experience a stinging sensation, but that should not last more than a minute or two; if the sensation persists, notify your doctor.

The eyedrop is supposed to be used within four weeks (4) of opening the bottle.

For postoperative pain of inflammation, instill one drop, three times daily, one day before cataract surgery, and continue on the day of the surgery and through the first two weeks (2) of the operative period. An additional drop should be administered 30 – 120 minutes prior to surgery.

Neparin is an eye drop that helps relieve symptoms such as pain, redness, swelling, itching, and watering of eyes after an operation of the eyes. This medication works by decreasing the production of some chemicals that cause inflammation of the eyes, making it easier for you to go about your daily activities. However, if you see no improvement even after a week of using it as prescribed, talk to your doctor. Neparin is a nonsteroidal anti-inflammatory drug (NSAID) that works by blocking the release of certain chemical messengers that cause pain and inflammation in the eye. It penetrates the cornea and converts ocular tissue hydrolase to Amfenac, a potent nonsteroidal anti-inflammatory drug. Amfenac is thought to inhibit the action of the cyclooxygenase enzyme. This enzyme is required for prostaglandin synthesis.
The common side effects of neparin eyedrop are foreign body sensation, ocular hyperemia, decreased vision, and watery eyes.Neparin should be used with caution in patients with known bleeding tendencies or who are receiving medications that may prolong bleeding time. During pregnancy, Neparin should only be used if the potential benefit justifies the fetus's potential risk. In lactating or nursing mothers, caution should be exercised when administering neparin ophthalmic suspension.Headaches, runny nose, sticky or itchy eyes can also be side effects of neparin.
The safety effectiveness of Neparin in pediatric patients below eighteen (18) years of age has not been established. People with diabetes are at increased risk/side effects that can cause the loss of sight. Anyone with diabetes needs to discuss with their doctor how this medication can/may affect their medical condition(s), how the medical condition may affect the dosing of the effectiveness of this medication, and whether any special monitoring is needed.You need to stop and seek immediate medical attention if you notice that your eyes become redder or more painful while using the drops, reduced vision, signs of a severe allergic reaction e.g, abdominal cramps, difficulty breathing, nausea or vomiting, or swelling the face and throat. Do not use any other medication unless your doctor asks you to, especially steroid eye drops.An overdose is not expected to be dangerous but seeks immediate medical attention if anyone has accidentally swallowed the medication. Neparin should not be used for dry eyes. It is used to prevent eye pains, irritation, and redness associated with cataracts and surgery. Ask your doctor if you are allergic to any eyedrop (in the past) before using neparin eyedrop.Note that neparin eyedrop is usually used for up to fourteen (14) days after the surgery or as directed by your doctor.
