Clinical Particulars
Section 4 of the official insert — extracted exactly as issued, no alterations
4.1 Therapeutic indications
BETAHISTINE 24 UNICORN is indicated for the symptomatic treatment of vertigo associated with Mu00e9niu00e8reu2019s syndrome.
4.2 Posology and method of administration
Posology: The usual dose is 24 mg to 48 mg of BETAHISTINE 24 UNICORN per day in divided doses. One 24 mg tablet can be administered twice daily. The dosage should be individually adapted according to the response.
Paediatric population: BETAHISTINE 24 UNICORN should not be used in children and patients under the age of 18 since safety and efficacy have not yet been established.
Method of administration: For oral use.
4.3 Contraindications
BETAHISTINE 24 UNICORN is contraindicated in:
- Patients with known hypersensitivity to betahistine or to any of the ingredients contained in BETAHISTINE 24 UNICORN (see section 6.1).
- Patients with phaeochromocytoma. Betahistine, a synthetic analogue of histamine, may induce the release of catecholamines from the tumour resulting in severe hypertension.
4.4 Special warnings and precautions for use
- Caution is advised in the treatment of patients with peptic ulcer or a history of peptic ulceration, because of the occasional dyspepsia observed in patients taking betahistine dihydrochloride.
- Patients with bronchial asthma should be monitored carefully for the duration of the treatment with BETAHISTINE 24 UNICORN.
- Caution is advised in prescribing BETAHISTINE 24 UNICORN to patients with either urticaria, rashes or allergic rhinitis, due to the possibility of aggravating these symptoms.
- Caution is advised in patients with severe hypotension.
- Caution is advised in patients with porphyria.
- If BETAHISTINE 24 UNICORN is to be administered subsequent to the treatment with an antihistamine and this treatment is stopped abruptly, withdrawal symptoms such as sleep disorders and agitation could appear due to the sedative action of antihistamines. Treatment with the antihistamine should be tapered over approximately six days.
4.5 Interaction with other medicines and other forms of interaction
There are no studies on the interactions with the following medicines: vasodilators, psychotropic medicines, in particular sedatives, tranquillisers and neuroleptics, parasympatholytics, and vitamins. Based on available data, no inhibition on cytochrome-P450 enzymes is anticipated. As betahistine is an analogue of histamine, BETAHISTINE 24 UNICORN should not be concomitantly administered with antihistamines as betahistine may in theory affect the efficacy of one of these medicines (see section 4.3). The metabolism of BETAHISTINE 24 UNICORN may be inhibited by medicines that inhibit monoamine-oxidase (MAO) including MAO subtype B (e.g. selegiline). Caution is recommended when using BETAHISTINE 24 UNICORN and MAO inhibitors (including MAO-B selective) concomitantly.
4.6 Fertility, pregnancy and lactation
Pregnancy: The safety of BETAHISTINE 24 UNICORN during pregnancy and breastfeeding has not been established. As a precautionary measure, it is preferable to avoid the use of betahistine during pregnancy.
Breastfeeding: It is not known whether betahistine is excreted in human milk, however it has shown to be excreted in rat milk, however studies are limited to very high doses.
Fertility: There is no data on fertility with BETAHISTINE 24 UNICORN.
4.7 Effects on the ability to drive and use machines
Vertigo, tinnitus and hearing loss associated with Mu00e9niu00e8re's syndrome can negatively affect the ability to drive and use machines. Occasional drowsiness may occur as a side effect associated with the use of BETAHISTINE 24 UNICORN. Patients should therefore not drive, use machinery or perform any tasks that require concentration, until they are certain that BETAHISTINE 24 UNICORN does not adversely affect their ability to do so (see section 4.8).
