Like other topically applied ophthalmic drugs, Otrivine-Antistin may be absorbed systemically and occasionally cause systemic sympathomimetic effects such as hypertension, nervousness, nausea, dizziness, headache, insomnia, palpitations, tachycardia, and arrhythmia.
Otrivine-Antistin should be used with caution in elderly patients with severe cardiovascular disease, including arrhythmia, poorly controlled hypertension or diabetes.
Use with caution in the presence of hypertension, cardiac irregularities, hyperthyroidism, diabetes mellitus or phaeochromocytomas.
Patients with long QT syndrome treated with xylometazoline may be at increased risk of serious ventricular arrhythmias.
Otrivine-Antistin should also be used with caution in patients with conditions causing urinary retention such as prostatic hypertrophy and should also be used in caution in patients who are currently receiving other sympathomimetic drugs.
Not suitable for patients suffering from dry eyes without first seeking medical advice. Rebound hyperaemia may follow prolonged frequent use. Otrivine-Antistin should not be used without supervision over a long period of time.
If the symptoms do not improve after 2 days, medical advice should be sought to rule out the possibility of a bacterial infection. Inflammation arising from infection should receive appropriate anti-bacterial therapy.
Eye drops are not for injection. They should never be injected subconjunctivally, nor should they be directly introduced into the anterior chamber of the eye.
This medicine contains 2.8 micrograms benzalkonium chloride in each drop, which is equivalent to 0.1 mg/ml.
Benzalkonium chloride may cause eye irritation, especially with dry eyes or disorders of the cornea. Patients should be instructed to talk to a doctor if they feel abnormal eye sensation, stinging or pain in the eye after using this medicine.
This medicine contains boric acid.
Otrivine-Antistin may impair fertility in the future as it contains boron. It should therefore not be administered to a child less than 2 years old.
