ISOPTO ATROPINE Ophthalmic solution Ref.[10851] Active ingredients: Atropine

5.1 Photophobia and Blurred Vision

Photophobia and blurred vision due to pupil unresponsiveness and cycloplegia may last up to 2 weeks.

5.2 Elevation of Blood Pressure

Elevation in blood pressure from systemic absorption has been reported following conjunctival instillation of recommended doses of atropine sulfate ophthalmic solution, 1%.

5.3 Increased Adverse Drug Reaction Susceptibility with Certain Central Nervous System Conditions

Individuals with Down syndrome, spastic paralysis, or brain damage are particularly susceptible to central nervous system disturbances, cardiopulmonary, and gastrointestinal toxicity from systemic absorption of atropine.

The following adverse reactions are described below and elsewhere in the labeling:

• Photophobia and Blurred Vision [see Warnings and Precautions (5.1)]
• Elevation in Blood Pressure [see Warnings and Precautions (5.2)]
• Increased Adverse Drug Reaction Susceptibility with Certain Central Nervous System Conditions [see Warnings and Precautions (5.3)]

The following adverse reactions have been identified following use of atropine sulfate ophthalmic solution. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

6.1 Ocular Adverse Reactions

Eye pain and stinging occurs upon instillation of atropine sulfate ophthalmic solution. Other commonly occurring adverse reactions include blurred vision, photophobia, superficial keratitis and decreased lacrimation. Allergic reactions such as papillary conjunctivitis, contact dermatitis, and eyelid edema may also occur less commonly.

6.2 Systemic Adverse Reactions

Systemic effects of atropine are related to its anti-muscarinic activity. Systemic adverse events reported include dryness of skin, mouth, and throat from decreased secretions from mucus membranes; drowsiness; restlessness, irritability or delirium from stimulation of the central nervous system; tachycardia; flushed skin of the face and neck.

7.1 Monoamine Oxidase Inhibitors

The use of atropine and monoamine oxidase inhibitors (MAOI) is generally not recommended because of the potential to precipitate hypertensive crisis.

Risk Summary

There are no adequate and well-controlled studies with ISOPTO Atropine 1% administration in pregnant women to inform a drug-associated risk. Adequate animal development and reproduction studies have not been conducted with atropine sulfate. In humans, 1% atropine sulfate is systemically bioavailable following topical ocular administration [see Clinical Pharmacology (12.3)]. ISOPTO Atropine 1% should only be used during pregnancy if the potential benefit justifies the potential risk to the fetus.

There is no information to inform risk regarding the presence of atropine in human milk following ocular administration of ISOPTO Atropine 1% to the mother. The effects on breastfed infants and the effects on milk production are also unknown. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ISOPTO Atropine 1% and any potential adverse effects on the breastfed child from ISOPTO Atropine 1%.

Due to the potential for systemic absorption of atropine sulfate ophthalmic solution the use of ISOPTO Atropine 1% in children under the age of 3 months is not recommended and the use in children under 3 years of age should be limited to no more than one drop per eye per day. Safety and efficacy in children above the age of 3 months has been established in adequate and well controlled trials.

No overall differences in safety or effectiveness have been observed between elderly and adult patients.
