Hi,
First of all, there are several causes of headache such as
hypertension, so we cannot diagnose migraine, unless we do several investigations to exclude organic causes. Second,
propranolol is used to treat migraine and it causes
depression. So, your father should stop the drug and measure his blood pressure, and it was high he would take medical treatment, decrease salt and fat intake, measure the
lipid profile in the blood and do an ECG and an ECHO on his heart.
If he did not have hypertension, he would take another drug such as
amitriptyline 50 mg. The dose should be half a tablet before bedtime for three days, then one tablet before bedtime. The drug can make him feel thirsty, so if he cannot tolerate the drug in the first three days, he should stop it immediately.
Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Mustafa, Neurologist
