Hello,
I can see why you'd be confused: the tinnitus in itself is stressing, and when starting a new medication and the headaches continue, it is hard to know whether this is the medicine or the original problem.
I will try and give you as clear a picture as possible based on what I usually see with patients on Betaserc, or
Betahistine.
Can Betaserc cause headaches? Yes, it can. Headache is, in fact, among the more common side effects of Betahistine. It doesn't happen in everyone, but in some, the
vasodilation that the medicine causes can result in morning headaches. Therefore, the timing you mentioned — taking a dose at night, and then waking with a headache, it does fit quite well with a Betaserc-related side effect. However, your original
dizziness and tinnitus can also cause headaches.
That is why it becomes tricky, as many patients with either
inner ear issues or tinnitus go on to develop tension headaches, poor sleep, and anxiety around the noise in the ear, which itself can cause morning heaviness of the head. So, I wouldn't say for sure that this is due to Betaserc only, but it definitely could be one of the possibilities.
Should you stop Betaserc on your own? My frank
medical opinion is that one should not stop it abruptly without consulting your ENT, particularly as he prescribed it on suspicion of inner ear nerve-related symptoms following vertigo and tinnitus. What I usually do for my patients is:
• Temporarily reduce the dose or
• Switch to once daily, and see if the headache eases (but that decision should come from the ENT who examined you)
I would suggest the following:
• Call or revisit your ENT and tell him exactly what you've told me
• Ask if you can reduce the dose or change the timing of intake
In the meantime, make sure you are always well hydrated as
dehydration can worsen Betaserc-related headaches. It is good that your blood pressure and sugar readings are normal. That already rules out some of the common causes of morning headaches. My clear view is, Yes, headaches are one of the side effects of Betaserc. Your symptoms do correspond to the time course of an adverse effect. Although, before stopping the medicine, consult with your
ENT specialist so that your tinnitus and vertigo treatment stays on course.
Take care. Hope I have answered your question. If you have any further query I will be happy to help. Wish you good health.
