Atropine sulfate ophthalmic gel is a paralyzing agent of the ciliary muscle and is relatively strong. Atropine will paralyze the ciliary muscle and dilate the pupil after use. It is usually used in children for dilated eye examinations or post-operative anti-inflammatory ophthalmology to relieve ciliary muscle spasm. After using atropine, it is important to avoid light because it will dilate the pupil. This causes more light to enter the eye and creates a stinging sensation. So you can wear a sun hat or sunglasses when you go out. In addition, children using this atropine ophthalmic gel may partially experience eye redness and fever, which is more obvious in the first 1-2 days and gradually improves after adaptation. In addition, when using atropine ophthalmic gel, you can press the root of the nose for 1-2 minutes, which will avoid excessive absorption of the mucous membrane, and the systemic side effects will be smaller.
