Bystolic is a
brand name for the generic drug Nebivolol. It is a kind of drug belonging to
the group of drugs called beta-blockers.
It works by affecting the reaction to nerve impulses in any part of the
body containing beta-receptors such as heart and blood vessels.
By affecting the nerve impulses in the heart, it will beat slower and thus, the blood pressure will decrease. If the heart beats slower, the amount of oxygen and blood to it will increase.
Bystolic is used to treat hypertension. It is part of a treating strategy which includes also diet, exercise and weight loss. It is also used to treat some types of heart failure, atrial fibrillation, to prevent chest pain or to prevent heart attacks in people who have already had a heart attack.
To make sure you can safely take Bystolic, you should tell your doctor if having one of the following conditions:
1. A heart problem such as heart attack, slow heart rate, heart failure, sick sinus syndrome.
2. Severe liver disease
If you have one of the following conditions, you should tell your doctor because you will probably need a dose adjustment or special test before starting Bystolic:
1. Lung diseases such as asthma, emphysema, bronchitis
2. Kidney or liver disease
3. Endocrine problems such as diabetes, thyroid problems, pheochromocytoma ( tumor of the adrenal glands)
4. Having allergies from Bystolic
5. Problems with circulation (such as Raynaud’s syndrome)
6. If having recently had a heart attack.
Bystolic is available only In tablet form. The daily dosage differs in different patients. The average dosages are 5 milligrams at firsts. Your doctor might increase the dose if needed. The use and dosage of Bystolic in children must be determined by the doctor.
Do not start taking Bystolic if not prescribed by your doctor.
DO NOT stop suddenly taking it, because this might make
your condition worse and might even cause serious heart problems such as heart
Bystolic slows the heart rate by blocking the beta receptors on the heart. Long-term use of Bystolic causes the upregulation of beta receptors, which means that heart cells increase the production of beta receptors, meaning this receptors over express themselves.
When one starts not to take the drug, or one decreases its dose suddenly, then norepinephrine and adrenaline will start to act on the beta receptors (which were prior blocked by Bystolic) and cause symptoms like palpitations, high blood pressure, anxiety and in the worst case heart attack.
Heart palpitation while weaning off Bystolic are very common. This is due to an improper wean off schedule.
Heart palpitations while weaning off
be prevented by following a proper plan scheduled by your doctor.
In order to wean off without any side effects, you must very gradually decrease the dose of Bystolic over the period of two weeks.
First, decrease the dose by 25% and take thus only 75% of the initial dose the first 4-5 days. Then decrease the dose by another 25% and use only 50% of the initial dose for another 4-5 days.
Then decrease the dose with another 25% of the initial dose and continue with the 25% of the initial dose for another 3-4 days. Then you can stop Bystolic completely.
Some patients find it very difficult to wean off Bystolic
while some others have no problems. This is due to the response to weaning off,
which differs in different people. In the case of finding it difficult, you should
talk to your doctor.
