Common side effects of atropine eye drops are blurred vision, dilated pupils, and possibly redness and fever in the eyes if used in higher doses or for a long time. Individual patients may also experience dry mouth, blurred vision, panic attacks, difficulty urinating, and constipation because atropine is a drug that inhibits cholinesterase activity. This can relax the muscles of the human digestive tract and bladder, thus exerting the above-mentioned effects, which are precisely the side effects. The side effects are related to the dose and duration of use, so the higher the dose and the longer the duration of use, the more likely it is to cause the above side effects. Therefore, it is necessary to use the medication under the guidance of a doctor’s prescription, and to give the appropriate dose for a short period of time, so as to ensure the safety of the medication to play a therapeutic role. However, if any intolerable reactions and symptoms occur during the use of the drug, you should stop the drug in time and consult your pharmacist or go to the hospital.
