2. QUALITATIVE AND QUANTITATIVE COMPOSITION

Each tablet contains 16 mg betahistine dihydrochloride, equivalent to 10.42 mg betahistine.

4.6 Fertility, Pregnancy and lactation

Pregnancy:
There are no adequate data from the use of betahistine in pregnant women.
Animal studies are insufficient with respect to effects on pregnancy, embryonal/foetal development, parturition and postnatal development. The potential risk for humans is unknown. Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity at clinically relevant exposure. As a precautionary measure, it is preferable to avoid the use of betahistine during pregnancy. Betahistine should not be used during pregnancy unless clearly necessary.

Lactation:
It is not known whether betahistine is excreted in human milk. There are no animal studies on the excretion of betahistine in milk. Betahistine is excreted in rat milk. Effects seen post-partum in animal studies were limited to very high doses. The importance of the drug to the mother should be weighed against the benefits of nursing and the potential risks for the child.

Fertility
Animal studies did not show effects on fertility in rats.

5.3 Preclinical safety data

Chronic toxicity
Adverse effects in the nervous system were seen in dogs and baboons after intravenous doses at and above 120 mg/kg.
Chronic oral toxicity testing for 18 months in rats at a dose of 500 mg/kg and 6 months in dogs at a dose of 25 mg/kg showed betahistine to be well tolerated with no definitive toxicities.
Studies on the chronic oral toxicity of betahistine dihydrochloride were performed in rats over a period of 18 months and in dogs over 6 months. Doses of 500 mg/kg in rats and 25 mg/kg in dogs were tolerated without changes in the clinical chemical and hematological parameters. There were no histological findings related to treatment at these dosages. After increasing the dose to 300 mg/kg, the dogs showed vomiting. In an investigational study with betahistine in rats over 6 months at 39 mg/kg and above hyperemia in some tissues was reported in the literature. Data presented in the publication are limited. Therefore, the impact of this finding in this study is not clear.

Mutagenic and carcinogenic potential
Betahistine does not have mutagenic potential.
In an 18 months chronic toxicity study in rats betahistine up to a dose of 500 mg/kg did not show any evidence for carcinogenic potential.
Special carcinogenicity studies were not performed with betahistine dihydrochloride. However, in the 18 months chronic toxicity studies in rats there was no indication of any tumors, neoplasms or hyperplasia in the histopathological examination. Therefore, betahistine dihydrochloride up to a dose of 500 mg/kg did not show any evidence for carcinogenic potential in this limited 18 months study.

Reproduction toxicity
Limited data are available for betahistine on reproduction. In a one-generation study in rats, an oral dose of 250 mg/kg/day betahistine had no adverse effect on male and female fertility, implantation of foetuses, parturition and viability of pups during lactation. No abnormalities were noted in weaned rats. In pregnant rabbits treated orally with 10 or 100 mg/kg betahistine, no adverse effects were noted on implantations, vitality or weight of foetuses, and no foetal skeletal or soft tissue abnormalities were noted. From these studies it can be concluded that betahistine has no detectable effects on relevant reproduction parameters in rat and rabbits in the described studies. Betahistine is not teratogenic. However, due to the investigational character of the studies a risk could not fully be excluded.
Effects in reproductive toxicity studies were observed only at exposures considered sufficiently in excess of the maximum human exposure indicating little relevance to clinical use.

4.2       Posology and method of administration

 

The usual dose is 8 to 16mg, three times daily taken preferably with meals.

 

Paediatric population:

Serc is not recommended for use in children below 18 years due to insufficient data on safety and efficacy.

 

Geriatric population:

Although there are limited data from clinical studies in this patient group, extensive post marketing experience suggests that no dose adjustment is necessary in this patient population.

 

Renal impairment:

There are no specific clinical trials available in this patient group, but according to post-marketing experience no dose adjustment appears to be necessary.

 

Hepatic impairment:

There are no specific clinical trials available in this patient group, but according to post-marketing experience no dose adjustment appears to be necessary.

 

 

4.3       Contraindications

 

Hypersensitivity to the active substance or to any of the excipients .

Use in phaeochromocytoma

 

 

4.4       Special warnings and precautions for use

 

Patients with bronchial asthma and history of peptic ulcer need to be carefully monitored during the therapy.

 

4.5              Interaction with other medicinal products and other forms of interactions

 

No in vivo interaction studies have been performed. Based on in vitro data no in vivo inhibition on Cytochrome P450 enzymes is expected.

 

In vitro data indicate an inhibition of betahistine metabolism by drugs that inhibit monoamino-oxidase (MAO) including MAO subtype B (e.g. selegiline). Caution is recommended when using betahistine and MAO inhibitors (including MAO-B selective) concomitantly.

 

As betahistine is an analogue of histamine, interaction of betahistine with antihistamines may in theory affect the efficacy of one of these drugs.

 

 

4.6       Fertility, Pregnancy and lactation

 

Pregnancy:

There are no adequate data from the use of betahistine in pregnant women.

Animal studies are insufficient with respect to effects on pregnancy, embryonal/foetal development, parturition and postnatal development. The potential risk for humans is unknown. Betahistine should not be used during pregnancy unless clearly necessary.

 

Lactation:

It is not known whether betahistine is excreted in human milk. There are no animal studies on the excretion of betahistine in milk. The importance of the drug to the mother should be weighed against the benefits of nursing and the potential risks for the child.

 

4.7       Effects on ability to drive and use machines

Betahistine is indicated for vertigo, tinnitus and hearing loss associated with Ménière's syndrome which can negatively affect the ability to drive and use machines.  In clinical studies specifically designed to investigate the ability to drive and use machines betahistine had no or negligible effects.

 

4.8       Undesirable effects

 

Gastrointestinal disorders

Common: nausea and dyspepsia

 

Nervous system disorders

Common: headache

 

In addition to those events reported during clinical trials, the following undesirable effects have been reported spontaneously during post-marketing use and in scientific literature. A frequency cannot be estimated from the available data and is therefore classified as “not known”.

 

Immune System disorders

Hypersensitivity reactions, e.g. anaphylaxis

 

Gastrointestinal disorders

Mild gastric complaints (e.g. vomiting, gastrointestinal pain, abdominal distension and bloating). These can normally be dealt with by taking the dose during meals or by lowering the dose.

 

Skin and subcutaneous tissue disorders

Cutaneous and subcutaneous hypersensitivity reactions, in particular angioneurotic oedema, rash, pruritus and urticaria.

 

 

 

4.9       Overdose

 

A few overdose cases have been reported. Some patients experienced mild to moderate symptoms with doses up to  640mg (e.g. nausea, somnolence, abdominal pain). More serious complications (e.g. convulsion, pulmonary or cardiac complications) were observed in cases of intentional overdose of betahistine especially in combination with other overdosed drugs.  Treatment of overdose should include standard supportive measures.
