Which medications may cause dizziness as a side effect?

　　In general, drug-induced dizziness as an adverse effect is related to the specific characteristics of the medication. Common drugs that may cause dizziness include Nifedipine Sustained-Release Tablets, Amiodarone Hydrochloride Tablets, Diazepam Tablets, Gentamicin Sulfate Injection, and Chlorpheniramine Maleate Tablets. Detailed explanations are as follows:

　　1. Nifedipine Sustained-Release Tablets: As a commonly used antihypertensive medication, Nifedipine Sustained-Release Tablets continuously lower blood pressure by slowly releasing nifedipine to maintain vasodilation. However, excessive blood pressure reduction caused by the medication may lead to insufficient cerebral blood supply, where blood flow cannot meet the brain's demands promptly, affecting normal brain function and consequently causing dizziness.

　　2. Amiodarone Hydrochloride Tablets: This antiarrhythmic drug regulates cardiac electrical activity and maintains stable heart rhythm. However, while exerting its effects in the body, Amiodarone Hydrochloride can interfere with the heart's normal pumping function, affecting the stability of the circulatory system and resulting in abnormal cerebral perfusion, which may lead to feelings of dizziness.

　　3. Diazepam Tablets: As a sedative-hypnotic medication, Diazepam acts on the central nervous system, suppressing neuronal excitability and helping patients relax and fall asleep. However, during this neuronal suppression, the regulation of bodily balance by the nervous system is disrupted, affecting vestibular function and causing inaccuracies in the perception of spatial orientation and body movement, leading to dizziness.

　　4. Gentamicin Sulfate Injection: After entering the body, this antibiotic may produce ototoxic effects, damaging the auditory and balance sensory organs of the inner ear. When structures such as the hair cells of the inner ear are damaged, the balance perception function becomes impaired, making it difficult for the body to accurately determine its movement status and spatial position, thereby causing dizziness.

　　5. Chlorpheniramine Maleate Tablets: As an antihistamine, Chlorpheniramine Maleate Tablets alleviate allergy symptoms by blocking the binding of histamine to its receptors. At the same time, it inhibits the central nervous system, interfering with neural signal transmission and affecting the brain's integration and coordination of bodily information, resulting in adverse reactions such as dizziness.

　　When taking medications, it is essential to strictly follow medical instructions and carefully read the drug insert regarding adverse reactions. If symptoms such as dizziness occur, prompt medical attention should be sought so that a physician can determine whether dosage adjustments, medication changes, or other treatment measures are necessary to ensure safe medication use.
