Precautions
This medication should not be used in patients with elevated intraocular pressure conditions such as primary glaucoma or angle-closure glaucoma. It should also not be administered to individuals who are hypersensitive to the components of this drug or to atropine, patients with severe myasthenia gravis, individuals with rapid heart rates due to heart failure, and patients with hyperthyroidism. Caution should be exercised when using this medication in patients with keratoconus, Down syndrome, children with brain injuries, the elderly, infants, and children, as well as patients who may have fever or are exposed to high temperatures. Rarely, this medication may cause neuropsychiatric side effects such as hallucinations or dizziness. Gastrointestinal symptoms like nausea, vomiting, and dry mouth may also occur. Cardiovascular side effects such as elevated blood pressure, heart palpitations, and vascular congestion may occur. Temporary eye pain or burning sensation may occur, and with prolonged use, conjunctivitis, eye irritation, congestion, and increased sensitivity to light may occur. Additionally, skin reactions such as facial flushing, swelling, exudation, and eczematous dermatitis may also occur. During the use of this medication, pupils being dilated should avoid driving or engaging in hazardous activities. Patients may become sensitive to light and should protect their eyes under bright lighting. Caregivers should ensure that this medication does not come into contact with children's mouths, and both caregivers and children should wash their hands thoroughly after administration. It is advisable to press the eyelid area for 2-3 minutes after administration to reduce systemic absorption of the medication. Measuring the depth of the anterior chamber of the eye is necessary to prevent the occurrence of angle-closure glaucoma. Caution is warranted if used in combination with tricyclic antidepressants, phenothiazine medications, or antihistamines, as the effects of this medication may be intensified. For pregnant women, the impact on the fetus is not clearly known, so it should only be used when necessary. While it is uncertain whether this medication is excreted in breast milk, most medications are excreted in breast milk, so nursing mothers should take particular care. With pediatric and infant patients, extra caution is essential. In cases of overdose, symptoms of psychiatric confusion such as delirium, anxiety, and rarely loss of consciousness may occur, particularly posing a higher risk of systemic side effects in children and the elderly. In such cases, an antidote called salicylate physostigmine should be used. This medication must be used exclusively as ophthalmic eye drops and should not be used as an injection. Care should be taken to prevent the tip of the container from coming into direct contact with the eye during administration, and joint usage should be avoided to prevent contamination.
