When taking betahistamine dihydrochloride should be stopped?

Betahistine dihydrochloride should be stopped if you experience severe side effects, such as allergic reactions (e.g., rash, itching, swelling), gastrointestinal issues (e.g., severe stomach pain, persistent nausea), or if your symptoms do not improve after a reasonable period. Additionally, discontinuation may be necessary if a healthcare provider advises it due to contraindications or interactions with other medications. Always consult your doctor before stopping any prescribed medication.
