Is there a reason a surgeon may prescribe beta blockers after surgery? Or as a preventative measure
Had headache, earache and watering eyefor 6 months had sinsus CT came back normal. Ent says headache is migraine and prescribed beta blocker. Correct?
Perhaps is migraine: Worthwhile to try a preventative medication, and beta blockers are approved for migraine, but, they may have nasty side effects such as wheezing, fatigue, cognitive slowing, exercise intolerance, slowing of pulse and dropping of blood pressure, and depression. Other meds may be tolerated better such as topirimate or divalproex sodium. Perhaps, see a neurologist who focuses in headache management. Read moreSee 2 more doctor answers
Cerebral perfusion: Beta blockers lower blood pressure, which is usually beneficial. However, if there is any problem with the blood flow to the brain, such as significant cerebrovascular disease or increased intracranial pressure, then lowering the blood pressure may undercut the perfusion to the brain--> could cause cerebral ischemia or even a watershed stroke.

Can lisinopril have the benefit of lowering a heart rate even though it may not be as effective as a beta blocker?
Beta blocker: Yes if given intravenous it will work right away, but if it is taken orally it will start working as soon as it is absorped in the blood stream. Read more
Since bystoilc is selective beta blocker (works on the heart only), can it still lower ocular pressure in glaucoma or does non selective bb is better?
Yes: Systemic beta blockers (bb) can lower iop, but not as effectively as when a topical ophthalmic preparation is used. Selective vs non- selective bbs very in their potency at blocking beta receptors in the eye & heart. Non-selective bbs block both types of receptors (b1 & b2) and lower iop more than selective type (b1). The later type is thought to be a safer medication with less pulmonary side effect.

What cold/ sinus medicines can I take safely with both hypertension and bad tachycardia (hr usually runs 120-150) even with a beta blocker?
Cold/Sinus meds: Hello, I have had many patients ask me the same question but they usually only have hypertension. With your additional unstable cardiac dysrhythmia, I would recommend you to avoid using any otc medications without first discussing these possible medications with your cardiologist. Otc suggestions like even a saline nasal wash can induce a new dysrhythmia. Read more

Why they say that it is dangerous to take beta blockers only and before alpha blockers in pheochromocytoma treatment? Is really life-threatening?
Yes, dangerous: Hi. Non-selective beta-blockers (e.g., propranolol) block beta-2 receptors, which mediate arterial relaxation. Pheos secrete epi and norepi, which activate alpha-1 and beta receptors. If you block vasodilatory beta-2's, then the arteries will see unopposed alpha-1 stimulation, which can cause a hypertensive crisis and stroke, death, etc. Block alpha-1 receptors first! Read more
Fatigue: Fatigue is the most common side effect, which may include daytime sleepiness. Erectile dysfunction may also occur. A beta- blocker also lowers heart rate and blood pressure, so if you are sensitive to it, or the dose is too large, bradycardia (low heart rate) or hypotension (low blood pressure) may occur.

Yes if it is a long: Acting preparation.Get a more detailed answer ›
How long does the involution phase last whenever a baby is put on the beta-blocker 'propranolol'?
Can nadolol 20mg be cut in half as a 10mg or will it conflict with the med chemistry because its a long acting beta blocker.?
Nadolol: If it has a score/line in the middle it can be cut and not change the chemistry or effects of it. Read more
Biochemistry: I suggest you go to Amazon and buy a biochemistry textbook if you really want to know. It's a bit too complicated to answer in 400 letters. Read more
