Maintaining balance is a complex process involving the brain, inner ear, muscles, and sensory nerves. As we age, this system becomes more vulnerable, and certain medications can interfere with its function, increasing the risk of dizziness, unsteadiness, and falls. Understanding which medications may affect balance is especially important for older adults.
1. Benzodiazepines
Used to treat anxiety, insomnia, and seizures, medications such as diazepam (Valium), lorazepam (Ativan) and alprazolam (Xanax) often cause drowsiness, dizziness, and impaired coordination. These effects significantly increase the risk of losing balance and falling.
2. Antidepressants
Drugs like amitriptyline, fluoxetine (Prozac) and sertraline (Zoloft) may lower blood pressure or affect brain signaling, leading to lightheadedness and instability, particularly when standing up.
3. Antipsychotics
Medications including haloperidol, risperidone (Risperdal) and olanzapine (Zyprexa) can cause sedation, muscle stiffness, and inner ear disturbances, all of which negatively affect balance.
4. Blood Pressure Medications
Amlodipine, metoprolol and lisinopril lower blood pressure. If blood pressure drops too much—especially when changing positions—it can lead to dizziness and loss of balance, a condition known as orthostatic hypotension.
5. Diuretics (“Water Pills”)
Drugs such as furosemide (Lasix) and hydrochlorothiazide reduce fluid volume in the body, which can lower blood pressure and cause dizziness, particularly in older adults.
6. Antihistamines
Common allergy and motion sickness medications like diphenhydramine (Benadryl), meclizine, and promethazine may cause drowsiness and confusion, interfering with coordination and balance.
7. Opioid Painkillers
Powerful pain medications including morphine, oxycodone, and hydrocodone depress the central nervous system, often causing sedation, dizziness, and instability.
8. Sleep Medications
Sleep aids such as zolpidem (Ambien) and eszopiclone (Lunesta) can cause grogginess and disorientation the next day, increasing the risk of balance problems and falls.
9. Anticonvulsants (Anti-Seizure Medications)
Drugs like phenytoin, carbamazepine, and gabapentin, used for epilepsy and nerve pain, may impair motor coordination and inner ear function, significantly increasing fall risk.
10. Chemotherapy Drugs
Certain chemotherapy agents, including cisplatin and vincristine, are neurotoxic and may damage the nerves responsible for balance and coordination, leading to dizziness and unsteady walking.
Important Safety Note
If you experience new or worsening balance problems, do not stop taking your medications without consulting your doctor. In many cases, your physician can adjust the dosage, change the medication, or manage side effects with safer alternatives.
Managing Medication-Related Balance Problems
-
Regular Medication Reviews – Periodically review all medications with your healthcare provider
-
Monitor Symptoms – Report dizziness, unsteadiness, or falls immediately
-
Lifestyle Adjustments – Practice balance exercises, stay well-hydrated, and maintain a safe home environment
-
Use Assistive Devices – Canes or walkers can provide additional stability when needed
