However, in this review we have focused on the more clinically relevant outcome of patientreported improvement. As a library, NLM provides access to scientific literature. Some studies suggest that betahistine is generally well tolerated[2] but there is some evidence of side effects generally gastrointestinal upset[1].

We excluded two as the participants did not meet the criteria for the symptom definition of vertigo according to the review protocol (Redon 2011; Schmidt 1992). Betahistine Helped My Severe Tinnitus two or more active treatments being tested against placebo), we established which of the comparisons were relevant to the systematic review and relevant to each of the metaanalyses that we implemented. The Information Specialist modelled subject strategies for databases on the search strategy designed for CENTRAL. Other causes of vertigo include neurological disorders affecting the central vestibular pathways (for example, some kinds of cerebellar stroke, or inflammatory or demyelinating pathologies) (Karatas 2010). Betahistine dihydrochloride in the treatment of peripheral vestibular vertigo, European Archives of Oto-Rhino-Laryngology. Low quality evidence suggests that patients suffering from vertigo from different causes may have some benefit from betahistine in terms of reduction in vertigo symptoms. Therapy with highdose betahistine (3 x 48 mg). Clusterrandomised trials allocate groups instead of individuals. Betahistine WebSee the list of drugs that interact with Betahistine. Betahistine Betahistine in the treatment of Mnire's disease WebBetahistine is given in pill form. The high rate of unwanted symptoms in the placebo group was notable. Betahistine We identified 32 potentially eligible studies and excluded 15 for reasons including having a crossover design with the data from before crossover not extractable, lack of adequate randomisation and ineligible participants. The pattern of symptoms of vertigo is variable.

NACRES: NA.24. 2HCl. betahistine The studies varied considerably in terms of types of participants, their diagnoses, the dose of betahistine and the length of time it was taken for, the study methods and the way any improvement in vertigo symptoms was measured. Vertigo is a symptom in which individuals experience a false sensation of movement. Where possible, take the tablets with something to eat. Take the betahistine packet or leaflet inside it, plus any remaining medicine, with you. Betahistine is frequently thought to cause upper gastrointestinal adverse effects. The incidence is estimated to be between 50 and 350 per hundred thousand per year ( Stahle 1978; Watanabe 1983 ). CAS Number: 5579-84-0. Low quality evidence suggests that in patients suffering from vertigo from different causes there may be a positive effect of betahistine in terms of reduction in vertigo symptoms. In a large German epidemiological populationbased study, the lifetime prevalence of vestibular vertigo was estimated at 7.4% (Neuhauser 2005). It is a commonly experienced symptom and can cause significant problems with carrying out normal activities. Comparison 1: Betahistine versus placebo, Outcome 3: Proportion of patients with adverse effects. A trial for 6-12 months of taking betahistine may be advised to see if it helps to reduce symptoms. Betahistine hydrochloride dosage. We created a funnel plot for this analysis, as more than 10 studies were included (Figure 5). [6] Under this therapy, all of them had 1 attack for 3 months prior to the combination pharmacotherapy. Includes information on severity of interaction and the level of evidence for it. Betahistine Tablets are not recommended for use in children below 18 years. WebAlthough the results of comparative studies between betahistine and other drugs (flunarizine, cinnarizine, and cinnarizine + dimenhydrate) are equivocal, the efficacy of betahistine is now clear. Total duration: 6 months. One study, at high risk of bias, included 72 people with benign paroxysmal positional vertigo (BPPV) and compared betahistine with placebo; all patients also had particle repositioning manoeuvres. Betahistine 24 mg twice a day versus placebo for 30 days, Randomised in groups of 4 before study started using tables, "neither patient nor investigator knew which treatment was being given". The evidence is up to date to September 2015. Level of blinding was dealt with in our 'Risk of bias' assessments, as is standard practice. Reporting bias can be assessed as betweenstudypublication bias or withinstudy reporting bias. Betahistine 1Although statistical heterogeneity (I2 statistic) was 64%, the direction of effects was consistent. For studies with ordinal data we checked, where possible, to see if the scale had been validated. Next review due: 24 August 2025, Taking betahistine with other medicines and herbal supplements, you take more than your prescribed dose of betahistine. Nauta 2014 is a review and metaanalysis focused on the outcome "investigator global assessment of benefit". 2 randomised lists (one for MD and one for BPPV) generated by the pharmaceutical company that supplied the drug and placebo tablets, using Fisher and Yates random number tables, "drugs supplied in identical packages with a fantasy name", Randomised patients all accounted for; low rate of attrition, Raw data frequently not given, only percentage change scores which are hard to interpret without baseline data. Duration of treatment available for analysis in this review was a fixed interval of two weeks (Burkin 1967; Guneri 2012; Okamoto 1968), one month (Duphar H10803592F 1997), five weeks (Oosterveld 1989), six weeks (Salami 1984), two months (Canty 1981; Duphar H108906NL 1990), and three months (Conraux 1988; Fischer 1985; Legent 1988; Mira 2003, Duphar 77054 1983; Duphar H10800580M 1984; Duphar H10802786F/M 1989). Webalmost time for your next dose, wait until that is due and continue as normal. Federal government websites often end in .gov or .mil. All subjects will be prescribed a nutritionally balanced mildly hypocaloric diet. LM, KH and AS drafted the final review. We planned to include crossover trials if the results from before the crossover were extractable, to avoid the potential for carryover effects. The prescribed diet will contain approximately 30% of calories from fat, 50% of calories from carbohydrates, and 20% of calories from protein. However, symptomatic management of vertigo may be required before a definitive cause can be identified. Six studies reported the frequency of attacks (Duphar H108906NL 1990; Duphar H10803592F 1997; Fischer 1985; Legent 1988; Mira 2003; Oosterveld 1989). There was one study that included patients with benign paroxysmal positional vertigo and it did not report DixHallpike tests as an outcome measure (Mira 2003). Betahistine is a widely used treatment for Mnire's disease or syndrome. Betahistine was associated with adverse events in 16% of participants; this was very similar to the rate in the placebo group (15%). Vertigo is a specific subtype of dizziness. Two authors (LM and KH) critically reviewed studies for risk of bias. The BEMED study referred to was not complete when the review was published. WebBetahistine is a structural analogue of histamine that is prescribed for the treatment of vestibular disorders such as Mnire's disease and the symptomatic treatment of vertigo. One study, at high risk of bias, included 72 people with benign paroxysmal positional vertigo (BPPV) and compared betahistine with placebo; all patients also had particle repositioning manoeuvres. The proportion of patients with adverse effects was 70/418 (16%) in the betahistine group and 61/401 in the placebo group (15%). Multi-variable analysis of the results of the double blind test and Fisher's evaluation method, Betahistine versus placebo in paroxysmal vertigo; a double blind trial. 'Risk of bias' graph: review authors' judgements about each risk of bias item presented as percentages across all included studies. The proportion of participants who withdrew or were lost to followup is recorded in Analysis 1.6. Dosage can be adjusted to suit individual patient needs. Betahistine Hydrochloride & Weight Loss. The review did not identify any subgroups that might particularly benefit from betahistine. WebMethods: Thirteen adults aged 40-75 years (mean 58.9 years; six females) had initially been treated with a high dosage of betahistine dihydrochloride for at least 1 year. If you have any further questions on the use of this product, ask your doctor or pharmacist. Forest plot of comparison: 1 Betahistine versus placebo, outcome: 1.2 Proportion of patients with improvement according to global judgement of patient: subgrouped by drug dose. Mira 2003 also used the Dizziness Handicap Inventory and some other scales whose validation references could not be obtained (Dizziness Assessment Rating Scale, GISFaV). When your symptoms are under control, your doctor may reduce your dose to 8mg, taken 3 times a day. Louisa Murdin has no interests to declare. In Canty 1981, some included participants in both groups had no symptoms at all throughout the whole trial duration, including the baseline assessment period, and this was also flagged up as a problem. A German study set in primary care found that betahistine was prescribed in 6.6% of consultations for dizziness, and was most likely to be prescribed in 'unspecified dizziness', vestibular neuritis and benign paroxysmal positional vertigo (Kruschinski 2008). The Brny Society and international collaborating organisations have recently published consensus clinical criteria for Mnire's disease (LopezEscamez 2015), taking forward the previously widely used American criteria (AAOHNS 1995). Betahistine This is 1 more than would have had similar symptoms if a sham medicine had been taken instead of betahistine. If the data were compatible and of sufficient quality we planned to combine them to give summary measures of effect. Canty 1981 presented vertigo scores that are not fully described in the methods and we judged this high risk. Sixteen per cent of patients from both the betahistine and the placebo groups withdrew (dropped out) from the studies (RR 0.96, 95% CI 0.65 to 1.42; 481 participants; eight studies). Associated symptoms and the quality of life also were significantly improved by This review and analysis were set up to answer the question, "is betahistine of overall benefit to patients with symptoms of vertigo?". Canty 1981, Fischer 1985, Guneri 2012, Legent 1988, Mira 2003, Okamoto 1968, Oosterveld 1989, Otto 2008, Salami 1984 and Ricci 1987 did report exclusion criteria. Adult: For the treatment of vertigo, tinnitus, hearing loss, and nausea associated with Meniere's disease: As betahistine dihydrochloride: Initially, 8-16 mg tid. When examining the effect of dose, there was evidence of a small effect in the studies using lower doses but not in the studies using higher doses. Adults: Initial oral treatment is 8 to 16 mg three times daily, taken preferably with meals. Betahistine We analysed subgroups by participant factors (diagnosis) and by intervention factors (dose of betahistine) to examine reasons for heterogeneity. Betahistine: Indications and Precautions - Step To Health Funnel plot of comparison: 1 Betahistine versus placebo, outcome: 1.1 Proportion of patients with improvement according to global judgement of patient: subgrouped by diagnosis. However, the dropouts occurred in the second phase of crossover, which is not relevant to the data considered for this review, so we deemed the study low risk. Maintenance doses are generally in the range 24 - 48 mg daily. Firstly, in terms of clinical diagnostic (intervention) factors, we considered whether heterogeneity could be reduced by looking at the diagnostic groups of benign paroxysmal positional vertigo (BPPV), Mnire's disease (by investigator diagnosis) or 'other vertigo' (Analysis 1.1). Betahistine is a pharmaceutical histamine regulator thats been used to treat vertigo for about 40 years. Currently patients are generally treated in general practice with betahistine (off-label use), while stronger evidence exists for the effectiveness of vestibular rehabilitation. In view of this, and the chronic and episodic nature of the condition of interest (vertigo), we used data from crossover trials only if data from before the crossover could be obtained. In addition, we are unsure about the quality of blinding of participants in the majority of studies. Canty 1981 reported assessing caloric tests at baseline and after treatment, stating that the test was abnormal in nine patients before treatment with "some improvement" in two of these. Betahistine is a drug treatment, available only in oral form, usually taken in doses from 24 mg to 48 mg daily. WebBetahistine add-on treatment in posterior benign paroxysmal positional vertigo resulted in improvements in both visual analog scale score and dizziness handicap inventory. Burkin 1967 used a "dizzy or not" dichotomous outcome. Mnire's disease is a progressive disease of the inner ear characterized by vertigo, tinnitus, and hearing loss. The review was not set up to analyse the size of any benefit since we examined only whether the patient judged that there was overall improvement of any degree, which makes it difficult for us to comment on how large the effect was. government site. Efficacy Study of Betahistine on The usual dose is one tablet three times daily.

For doses of betahistine under 48 mg per day, the pooled risk ratio was 2.11 (95% CI 1.03 to 4.30; 292 participants; six studies) in favour of betahistine, with the caveat that statistical heterogeneity was again high (I2 = 89%). official website and that any information you provide is encrypted Betahistine WebBetaserc (Betahistine): Uses, Side Effects, Dosage. How and when to take betahistine - NHS WebDosage and strength. Primary outcome measures were mostly by self report, unsurprisingly, given the subjective nature of vertigo symptoms. This type of dizziness is thought to originate in the inner ear labyrinth or its neural connections. The usual starting dose is 16mg, taken 3 times a day. We calculate that this gives a P value of 0.006 (Fisher's exact test). Numbers lost in each treatment arm unclear. Duphar 77054 1983, Duphar H10802786F/M 1989 and Duphar H10803592F 1997 included patients with Mnire's disease or episodic vertigo with cochlear symptoms, but with no strict diagnostic criteria and with other diagnoses included. Initially 16 mg 3 times a day, dose preferably taken with food; maintenance 2448 mg daily. The daily dose should be given in 2 or 3 divided doses throughout the day. Burkin 1967, Guneri 2012 and Ricci 1987 gave no information on attrition and we judged them unclear risk on this basis. 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. None of the included studies compared different doses of betahistine within the same protocol. Randomised controlled trials. WebAlthough betahistine is thought to be specifically effective for Mnire's disease, no evidence for a benefit from the use of betahistine exists, despite its widespread use. Analysis was "as treated". Betaserc Dosage It has been used in some countries for many years as a treatment for Mnire's disease or syndrome, where it has been thought to be especially effective for the symptoms of vestibular vertigo. We used the GRADE approach to rate the overall quality of evidence. Patients and their doctors will want to know whether the overall benefit from betahistine, if there is one, is large or small, and whether it is worth the risk of developing adverse effects. Mnires Society Proportion of participants with falls, as a reallife indicator of overall functional balance. Ikuti petunjuk yang ada di kemasan atau sesuai anjuran dokter; Betahistine bisa dikonsumsi baik sebelum maupun sesudah makan Bilastine There are no studies awaiting assessment and two studies are ongoing.

Bias in meta-analysis detected by a simple, graphical test, Cochrane Handbook for Systematic Reviews of Interventions Version 5.1.0 [updated March 2011]. All studies with analysable data lasted three months or less. It may be a sensation of rotation ('spinning vertigo'), or may be a different sensation of self motion ('nonspinning vertigo'). Other indications have also been studied, such as the treatment of Mnires disease and benign paroxysmal positional vertigo (BPPV). The mean plasma elimination half-life is 3 to 4 hours, and We planned to analyse all participants according to the group randomised in the studies. Our findings also suggest that high-dose betahistine (72 mg/d) is safe in the Chinese Han population. To prevent stomach upset, it is recommended that this medication be taken with food. It usually causes vertigo with a feeling of dizziness, hearing loss, and tinnitus. Betahistine undergoes extensive first-pass metabolism to the major inactive metabolite 2-pyridyl Betahistine is generally well tolerated with a low risk of adverse events. As 25 mg tab: 6-12 years 12.5 mg to be taken at least 30 minutes before travel, may be repeated 6 hourly if necessary; 13 years Same as adult dose. About betahistine Mnire's disease is a condition of the inner ear. One patient in Mira 2003 was recorded as having dysmyelopoiesis on betahistine. Groups appear well matched in Okamoto 1968 and all the unpublished manufacturer trials (Duphar 77054 1983; Duphar H10800580M 1984; Duphar H10802786F/M 1989; Duphar H10803592F 1997; Duphar H108906NL 1990). Do not take two doses within approximately two hours of each other. We judged the quality of evidence overall to be low. Betahistine 24 mg twice a day (BID) (48 mg/day total), Betahistine 48 mg BID (96 mg/day total), Matching placebo. Where there was a sufficient number of trials (more than 10) in any metaanalysis, we assessed publication bias according to the recommendations on testing for funnel plot asymmetry as described in Section 10.4 of the Cochrane Handbook for Systematic Reviews of Interventions (Egger 1997; Handbook 2011).

Nauta did not consider risk of bias in underlying studies, nor other outcomes than investigator global opinion. Duphar H10800580M 1984 included patients labelled as having "central signs" with shortlived episodes of vertigo, this list including changes in handwriting, spontaneous or induced/gaze evoked nystagmus, nystagmus on cervical or vertebrobasilar privation test and unilateral or bilateral hypo or hyperexcitability of vestibular function (Duphar H10803592F 1997). What are the downsides of this treatment? 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. Two different review authors independently dichotomised these into 'improved' or 'not improved' whenever possible. The electronic database search on 21 September 2015 identified 809 records. Benign paroxysmal positional vertigo is diagnosed according to clinical criteria, as is vestibular neuritis (Strupp 2013). As betahistine mesilate: 6-12 mg tid. There was no information on the effect of betahistine on overall quality of life or falls. A Scottish study estimated that 21% of the population had experienced vertigo and 16% of these found the symptoms moderately or severely disruptive (Hannaford 2005). Pooling the results for upper gastrointestinal effects gives a risk ratio of 1.38 (95% CI 0.67 to 2.82; 587 participants; six studies) (Analysis 1.4). betahistine Though the pharmacologically approved dosage is only 48 mg/day, many, if not most, patients especially those with Mnires disease need much higher doses for any clinically observable benefit with this dose. 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.

Duphar H10802786F/M 1989 described coding envelopes all being returned unopened, but opacity was not stated so we rated this as unclear. Okamoto 1968 used a threepoint, authordefined ordinal scale to measure intensity of vertigo. Betahistine Vertigo is a symptom in which individuals experience a false sensation of movement. Webalmost time for your next dose, wait until that is due and continue as normal. Betahistine is a strong H3 antagonist and a weak H1 agonist26with three sites of action. Psychological disorders and primary cardiological disorders can also cause a sensation of vertigo (NewmanToker 2008; Wiltink 2009). Six studies reported no adverse events in either the placebo or betahistine groups (Burkin 1967; Canty 1981; Duphar H10800580M 1984; Fischer 1985; Okamoto 1968; Salami 1984). We excluded six studies as there was no evidence of randomisation (Bertrand 1972; Hommes 1972; Purohit 1988; Singarelli 1979; Verspeelt 1996), or randomisation was inadequate (Elia 1966). 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). Betahistine is thought to cause upper gastrointestinal adverse effects and we recorded these separately. It does not affect hearing loss or tinnitus.
