Treatment Overview:
Betahistine is administered orally in the form of pills, intended for individuals experiencing tinnitus.

Potential Adverse Effects:
While some research indicates that betahistine is generally well-received by patients, there have been reports of side effects, primarily gastrointestinal disturbances.

Research Insights:
There has been a body of research investigating the efficacy of betahistine in treating tinnitus.

Conclusions from Research:
The available studies have not demonstrated a significant difference in the loudness of tinnitus, the severity of tinnitus symptoms, or the occurrence of side effects between individuals treated with betahistine and those given a placebo.

Reflecting on the current evidence, the NICE guidelines advise against the use of betahistine specifically for the treatment of tinnitus.
