Thanks for writing your query.
It will be more helpful if you mention all the medicines your husband is taking.
Zapiz contains clonazepam
. It should not be stopped abruptly as it may cause withdrawal symptoms
. It should be tapered down, under medical supervision, before stopping.
The cause of his symptoms can be commented after clinical examination and investigations.
For acidity and gas, he can take Omeprazole
40 mg once a day along with Domperidone
He should avoid spicy/oily foods, mental stress.
He should drink lots of water daily.
I would also advise a MRI of head and neck to rule out other causes of dizziness
. Also an ENT check up and a clinical examination by a Neurophysician can be helpful.
I hope this is helpful to you.
