Bisoprolol is a beta-blocker active ingredient used to treat high blood pressure and angina pectoris. The most common side effects with bisoprolol include headache, dizziness and tiredness. If the drug is suddenly discontinued, more serious side effects may occur. We inform you comprehensively about side effects, contraindications, interaction as well as the dosage of bisoprolol.
Beta blocker bisoprolol
The active ingredient bisoprolol belongs to the group of beta-blockers (beta-receptor blockers). It is used to treat essential hypertension and stable angina pectoris. In addition, bisoprolol can be used with other medicines for chronic heart failure.
Active ingredients from the group of beta-blockers occupy the beta-receptors in the heart. As a result, the hormone adrenaline can no longer dock on these receptors. Among other things, adrenaline in the body ensures that cardiac output and blood pressure rise.
By taking beta-blockers such as bisoprolol, the heart beats slower and less powerful and the blood pressure drops. In addition, the heart consumes less energy and oxygen, which alleviates typical angina symptoms such as breathing difficulties and pain in the heart area.
Side effects of bisoprolol
Just as with other active ingredients, the administration of bisoprolol may also cause side effects. Frequently symptoms such as headache, dizziness, sensory disturbances, fatigue and exhaustion occur.
Occasionally, the following side effects may occur while taking the beta-blocker:
- Confusion, mood swings, depression and sleep disorders
- Circulatory disorders
- Muscle weakness and joint disease
- Rashes and itchy skin
- slowed heartbeat, impaired heart function and drop in blood pressure when getting up from sitting or lying down
- Gastrointestinal complaints such as nausea, vomiting, diarrhea, constipation and abdominal pain
Rarely, after taking bisoprolol, there are also side effects such as a reduced flow of tears, an increase in blood lipids, respiratory disorders, sweating, difficulty taking pleasure and weight gain.
Dosage of bisoprolol
How precisely bisoprolol is dosed must be determined individually by the treating physician. Please understand the following dosage information only as a general guide. As a general rule, intake starts with a low dose, which can be gradually increased as needed.
When bisoprolol is used to treat high blood pressure or angina pectoris, it is usually started at a dose of five milligrams per day. If necessary, the dose can be increased to 10 milligrams per day. In exceptional cases, a further increase in the dose is possible. If only a slight hypertension is present, the administration of 2.5 milligrams of bisoprolol may already be sufficient.
If you have overdosed bisoprolol, you should contact a doctor immediately. Depending on how high the dose was, it can lead to serious side effects. These include a sharp fall in blood pressure, a slow heart rate, heart failure and cardiogenic shock. In addition, impaired consciousness, difficulty breathing and nausea and seizures may occur.
Without consultation with a doctor, neither the dosage of bisoprolol should be changed nor the beta-blocker should be discontinued. Otherwise, a deterioration in the condition of the patient may be the result. If bisoprolol is discontinued, this is usually done by gradually reducing the dose. It usually takes between three and ten days for the drug to be completely discontinued.
If bisoprolol is discontinued abruptly, it can lead to dangerous side effects. These include a reduced perfusion of the heart muscle with renewed exacerbation of angina pectoris, a heart attack and a rapidly recurring high blood pressure.
