Bosu usually refers to bisoprolol fumarate tablets, a medication used to treat hypertension, angina pectoris, and chronic stable heart failure. Possible side effects include cardiovascular reactions, central nervous system discomfort, respiratory symptoms, gastrointestinal abnormalities, and metabolic or musculoskeletal reactions, most of which are related to dosage and individual tolerance. If severe symptoms such as bradycardia, difficulty breathing, or fainting occur, immediate medical attention is recommended.

1. Cardiovascular reactions: May cause bradycardia and decreased blood pressure. Some individuals may experience palpitations or chest tightness. In patients with pre-existing heart conditions, conduction block may worsen. Heart rate and blood pressure should be closely monitored, especially during the initial phase of treatment.

2. Central nervous system discomfort: Commonly includes dizziness, headache, fatigue, and weakness. Some people may develop sleep disturbances, vivid dreams, or difficulty concentrating. These symptoms typically appear early in treatment and tend to gradually improve as tolerance develops.

3. Respiratory symptoms: May induce bronchospasm, manifesting as cough, wheezing, and shortness of breath. Patients with asthma or chronic obstructive pulmonary disease (COPD) are at higher risk; therefore, the indication for use must be strictly evaluated.

4. Gastrointestinal abnormalities: Occasionally includes nausea, vomiting, abdominal pain, diarrhea, or loss of appetite. Symptoms are generally mild and associated with minor effects of the drug on gastrointestinal smooth muscle. Taking the medication with food may help reduce discomfort.

5. Metabolic and musculoskeletal reactions: May affect glucose and lipid metabolism, leading to elevated blood sugar or abnormal lipid levels. Some individuals may experience muscle pain or weakness. Long-term users should have metabolic parameters regularly monitored.

Medication must be taken strictly according to medical instructions—do not adjust the dose or discontinue the drug abruptly. Dose reduction should be gradual when stopping treatment. Maintain a regular lifestyle, avoid strenuous exercise, follow a light, low-salt diet, quit smoking, limit alcohol intake, and undergo regular check-ups for cardiac function and metabolic indicators.
