Some eye drops are made simply of a saline (salt and water) solution and are harmless if swallowed. But those eye drops, which contain dangerous ingredients such as tetrahydrozoline, boric acid, hydrochloric acid, parabens, alcohol and mineral oil and so on, are potentially harmful. In addition to, prescription eye drops, those you cannot get without a doctor's recommendation, meant to treat more serious conditions, are of ingredients more powerful and more concentrated, and they are more harmful than over-the-counter versions.
If harmful eye drops are ingested, a person could experience blurred vision, nausea, vomiting, diarrhea, difficulty breathing, dangerously low body temperature, fluctuating blood pressure and even seizures. Under this situation, call a poison control center immediately. Tell the nurse when the drops were ingested and how much. Follow her instruction carefully and do not try to deal with the problem yourself.
