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, palpitation, 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.
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 product should not be used in patients receiving monoamine oxidase inhibitors or within 14 days of stopping such treatment (see section 4.3 Contraindications).
Sedating anti-histamines can enhance the sedating effects of CNS depressants including alcohol, hypnotics, opioid analgesics, anxiolytic sedatives, and anti-psychotics. They also have an additive anti-muscarinic action with other anti-muscarinic drugs, such as atropine, and some antidepressants. Otrivine-Antistin should be used with caution in patients receiving other medications such as digitalis, beta-adrenergic blockers, guanetidine, reserpine, methyldopa or anti-hypertensive agents. Concurrent use with halogenated anaesthetic agents such as chloroform, cyclopropane, halothane, enflurane of isoflurane may provoke or worsen ventricular arrhythmias.
In line with common practice, the use of medication during pregnancy is not recommended unless considered essential.
It is not known whether the active ingredients are distributed in human milk. It should therefore not be administered to nursing mothers or breast feeding should be interrupted for 48 hours after administration.
Any patient who experiences blurred vision should not drive or operate machine.
Otrivine-Antistin is generally well tolerated. In a few cases, slight transient local stinging on instillation has been reported. Other side effects which have been reported very occasionally are blurred vision, mydriasis, headache, drowsiness and reactive hyperaemia.
Local allergic reactions (e.g. rash, oedema, pruritus) and eye irritation have also been reported post-marketing.
Systemic side effects, which may occur in sensitive patients, are tachycardia (especially in small children), palpitations, arrhythmia, hypertension, occipital headache, nausea, paleness and sweating.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme. Website: www.mhra.gov.uk/yellowcard
Excessive dosage and or prolonged or too frequent use of xylometazoline hydrochloride, especially in children, may cause adverse systemic effects. Excessive dosage in children may cause profound CNS depression possibly necessitating intensive supportive care. CNS depression, shock-like hypotension, and coma have occurred following overdose of naphazoline and tetrahydrozoline; the possibility that this may occur with xylometazoline should be kept in mind.
Otrivine-Antistin is a combination of a long acting vasoconstrictor, xylometazoline and an antihistamine, antazoline.
Xylometazoline is a sympathomimetic agent with marked alpha-adrenergic activity. It acts as a vasoconstrictor which reduces eye redness.
Antazoline is an H1 receptor antagonist. It has antihistaminic, anticholinergic and local anaesthetic properties. The primary mediator of inflammation in allergic conjunctivitis appears to be histamine. Antazoline reduces histamine induced responses including itching. In clinical studies, Otrivine-Antistin was shown to cause a small mydriatic response but no change in intraocular pressure. The mydriatic response is too small to be of clinical significance or to impose any risk of pupil block or irido-corneal angle glaucoma, even in susceptible subjects.
No formal studies have been conducted.
There are no other clinically relevant preclinical safety data in addition to those mentioned in other sections of the SmPC.
