Restasis is a medication used to treat chronic dry eye. It is designed to reduce inflammation caused by various conditions and stimulate the production of natural tears. Unfortunately, some people taking Restasis may experience burning sensations in their eyes. Burning sensations in the eyes while taking Restasis is an example of an adverse effect, or a side effect that may be caused by the medication. Generally, the burning is mild, but it can be quite uncomfortable for some people. It is also important to note that eye burning can be a sign of dry eye, so it is important to consult with a doctor before taking the medication. If the burning sensation persists after taking Restasis, it is important to notify a doctor right away. It may indicate that the medication is not working as it should and could be causing more damage than benefit. It is also important to discontinue use of the medication and make an appointment with an eye doctor if the burning is severe. Although burning may be a side effect of taking Restasis, it is not common. Most people who take the medication experience no side effects at all. If a person does experience burning, it is likely due to individual sensitivity to the medication and can be reduced or eliminated by taking the medication at different times of the day or decreasing the dosage.
