Seven studies collected parallel data on the investigator global impression of treatment (Fischer 1985; Duphar H108906NL 1990; Duphar 77054 1983; Duphar H10802786F/M 1989; Duphar H10800580M 1984; Duphar H10803592F 1997; Mira 2003). This review examines whether betahistine is more effective than a placebo (sham medicine) at treating symptoms of vertigo from different causes in patients of any age. WebBetahistine dihydrochloride | C8H14Cl2N2 | CID 68643 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. Two studies did not report age and gender data for participants (Conraux 1988; Legent 1988). On the other hand, it probably does not have significant adverse effects. WebThe betahistine dosage was 16 mg twice per day for 3 months. The majority of studies were singlecentre and appeared to take place in specialist centres. Mnires Society However, with an intervention that is in tablet form, blinding should be straightforward to achieve. Reasons given for 28 of these. We calculate that this gives a P value of 0.006 (Fisher's exact test). If sufficient data were available for different conditions (e.g. betahistine Pooling data was inappropriate for this outcome given the diversity of techniques used to measure vestibular function. We included 17 studies, with a total of 1025 participants. Even if this drug is covered by Medicare or your insurance, we recommend you compare prices. Leave 6 to 8 hours between doses. Language was not a barrier to inclusion and we included papers in French, Italian, Japanese and Dutch. "Physician doing Epley manoeuvre did not know who would be allocated." There was no significant difference between the betahistine and placebo groups in any study or in the pooled analysis. 11 dropouts in betahistine group and 15 in placebo group; reasons unclear.

One patient in Duphar H108906NL 1990 had respiratory distress on betahistine and one patient in Duphar H10803592F 1997 had an asthma attack on betahistine. The drug is generally well tolerated [ 1 ]. Betahistine Tablets are not recommended for use in children below 18 years. Estimates of the prevalence of significant vertigo impacting on daily life range from 3% to 10% (Murdin 2015). Where patients were diagnosed with a specific vestibular condition, we noted the diagnostic criteria. This type of dizziness is thought to originate in the inner ear labyrinth or its neural connections. None of the authors have any conflicts of interest in the conduct of the review, particularly in relation to the pharmaceutical manufacturer of betahistine. These symptoms are usually not serious and subside in between doses. However, the GRADE assessment for this outcome was also 'low', suggesting that the result should be interpreted with caution. The betahistine works wonderfully well. Repeated-measure analysis of variance was used to test (1) the effects of betahistine treatment (controls vs. treated cats), (2) the effects of the betahistine dose (0.2 vs. 2 mg/kg), and (3) the effects of additional selegiline on the lowest betahistine dose (0.2 mg/kg betahistine + 1 mg/kg selegiline). Using the GRADE system, we judged the quality of evidence overall to be low for two outcomes (proportion of patients with improvement and proportion with adverse events). If you need to go to A&E, do not drive yourself. One study included patients with "vertebrobasilar ischaemia", defined in this study as vertigo with at least two of impaired hearing, impaired vision, tinnitus or headache and "typical abnormalities" on test, which were not specified (Otto 2008). We assessed the variation in treatment effects by means of the Cochrane test for heterogeneity and quantified it using the I2 statistic. Of the 17 studies included, five were unpublished trials, but the manufacturers could provide us with data. This type of dizziness is thought to originate in the inner ear balance organ or its connections to the brain. Keywords: Betahistine; Dizziness; Epley maneuver; Quality of life; Vertigo.

You may need to take betahistine for a long time, such as several months or years, to prevent the symptoms of Mnire's disease. Insurance does not cover betahistine. Unsurprisingly, perhaps, given its lack of specificity, the experience of dizziness is common. Similarly, in this study, we found that combination therapy with cinnarizine (75 mg) and betahistine (24 mg) has superior efficacy and tolerability compared with those of respective monotherapies. SERC contains the active ingredient betahistine dihydrochloride. Cinnarizine, proactively prevented vertigo spells especially in MD patients with migrane: Peripheral vertigo We resolved differences of opinion by discussion in the first instance, with input from the third author (AS) if necessary. Usually for adults, administer orally 6 mg to 12 mg three times per day after meals. For each study, we extracted information on study design, duration, randomisation, concealment, number of participants, setting of study, diagnostic criteria and exclusion criteria, age and sex distribution of participants, country of recruitment, comorbidity, date of study, number of intervention groups, betahistine dose and duration, outcomes measured and definition of outcomes, missing data and final sample size, data on intensity, frequency and duration of vertigo, and data from other vertigo scales. Betahistine comes as 8mg or 16mg tablets. The usual starting dose is 16mg, taken 3 times a day. Leave 6 to 8 hours between doses. When your symptoms are under control, your doctor may reduce your dose to 8mg, taken 3 times a day. Swallow the tablet whole with a drink of water. It's a good idea to take your betahistine tablets after a meal. Betahistine could also have effects on symptoms of vertigo via central nervous system activity. No placebo patients reported these effects. For the DHI, the authors reported that the placebo group had a mean score 12.15 (95% CI 10.5 to 13.4) at one week, and the betahistine group had a mean score of 10.42 (95% CI 4.7 to 16.1). tolerability of betahistine in patients with vestibular [12] Dose changes are not required for hepatic or renal impairment. Swallow the tablet whole with a drink of water. Betahistine comes as 8mg or 16mg tablets. Since 2016, I am waiting for the Cochrane review to be updated to include this extremely important RCT. Daily dose should not exceed 48 mg. The authors suggested, however, that due to difficulties with adherence to the strict diagnostic criteria for Mnire's syndrome, a true positive effect of betahistine in patients with less welldefined symptoms may have been missed. There was no blinding of journal, author names or affiliations. 8 mg tablets: one or two. The studies varied considerably in terms of types of participants, their diagnoses, the dose of betahistine and the length of time the drug was taken for, the study methods and the way any improvement in vertigo symptoms was measured. Risk of bias is presented graphically in Figure 2 and Figure 3. official website and that any information you provide is encrypted Betahistine Nauta found a beneficial effect of betahistine over placebo for both Mnire's disease and vestibular vertigo, calculating a pooled odds ratio (OR) of 2.58 (95% CI 1.67 to 3.99), with subanalyses conducted for patients with Mnire's disease (OR 3.37, 95% CI 2.14 to 5.29) and for vestibular vertigo (OR 2.23, 95% CI 1.20 to 4.14). There were no language, publication year or publication status restrictions. Given that the BEMED trial has clearly shown the absence of any therapeutic effect of Betahistine, the obvious question arises: Is Cochrane getting money from the Betahistine industry? WebBetaserc (Betahistine): Uses, Side Effects, Dosage. Leave 6 to 8 hours between doses. Although Mira 2003 collected data using the validated Dizziness Handicap Inventory (DHI), the results were reported only as percentage reductions with no baseline absolute values and missing measures of spread, so no useful data could be extracted. When your symptoms are under control, your doctor may reduce your dose to 8mg, taken 3 times a day. betahistine Betahistine hydrochloride is a weak histamine H1 agonist and a strong H3 antagonist with virtually no H2 histamine receptor activity. Betahistine is a pharmaceutical histamine regulator thats been used to treat vertigo for about 40 years. It is excreted via the urinary system. Mira 2003 reported that drugs were supplied in identical packages with a false name, so we awarded it a low risk rating. No published studies excluded those who had previously been on betahistine, but two unpublished studies did (Duphar H10803592F 1997; Duphar H108906NL 1990). Start at a low dose.maybe 4mg 3Xday and every couple weeks titrate up until at least 16mg 3Xday. Ten studies collected data on patient global satisfaction with treatment using various different ordinal scales, which we interpreted as overall improvement where the rating was positive (Conraux 1988; Duphar H108906NL 1990; Duphar 77054 1983; Duphar H10800580M 1984; Duphar H10803592F 1997; Fischer 1985; Legent 1988; Mira 2003; Oosterveld 1989; Otto 2008). Salami 1984 reported that in the betahistine group, in 13 patients with abnormal tests at baseline 10 patients (77%) had normalisation after six weeks of treatment. Burkin 1967 did not report exclusion criteria. These results need to be interpreted with caution as the diagnosis of Mnire's disease was investigatordefined and did not necessarily meet standard criteria. The Cochrane ENT Information Specialist searched the Cochrane ENT Trials Register; Central Register of Controlled Trials (CENTRAL 2015, Issue 8); PubMed; EMBASE; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials.
