Betahistine can cause fast heart rate and insomnia. Tachycardia, or a fast heart rate, can be a reaction to the low blood pressure that this medicine can cause. Insomnia can be the result of the pharamceutical acting on the histamine receptors (H1) in the brain. You can return to your doctor and describe your symptoms to find an alternative medication/treatment plan for the original ear problem.
