10 Common Medications That Can Cause Loss of Balance

News · January 19, 2026 · 0 Comment

 

Balance depends on a finely tuned system involving the brain, inner ear, nerves, muscles, and blood pressure. As we age, this system becomes more sensitive, and certain commonly prescribed medications can disrupt it—sometimes subtly, sometimes significantly. The result may be dizziness, unsteady walking, or an increased risk of falls.

Below are 10 categories of medications most often associated with balance problems. Not everyone will experience these effects, but awareness is important—especially for older adults.

1. Benzodiazepines (anxiety and sleep medications)

Examples: diazepam, alprazolam, lorazepam

These medications slow brain activity and can cause:

  • Drowsiness
  • Poor coordination
  • Slower reflexes

They are a well-recognized contributor to falls, particularly in older adults.

2. Antidepressants

Examples: amitriptyline, fluoxetine, sertraline

Possible effects include:

  • Lowered blood pressure
  • Changes in brain signaling
  • Lightheadedness when standing

This can create a sense of instability or faintness.

3. Antipsychotics

Examples: haloperidol, risperidone, olanzapine

These may lead to:

  • Muscle stiffness
  • Sedation
  • Effects on inner-ear balance

All of which can interfere with normal movement and gait.

4. Blood pressure medications

Examples: amlodipine, metoprolol, lisinopril

Some can cause orthostatic hypotension—a sudden drop in blood pressure when standing—resulting in:

  • Dizziness
  • Brief blackouts
  • Falls

5. Diuretics (“water pills”)

Examples: furosemide, hydrochlorothiazide

By reducing fluid levels, they may:

  • Lower blood volume
  • Reduce blood pressure
  • Cause weakness or dizziness

6. Antihistamines (allergy and motion-sickness medications)

Examples: diphenhydramine, meclizine, promethazine

Common effects include:

  • Drowsiness
  • Confusion
  • Poor coordination

These effects are especially risky at night.

7. Opioid pain medications

Examples: morphine, oxycodone, hydrocodone

They depress the nervous system and can cause:

  • Sedation
  • Dizziness
  • Loss of balance

Fall risk increases significantly with these drugs.

8. Sleep medications

Examples: zolpidem, eszopiclone

These may cause next-day grogginess, slowed reaction time, and confusion—making walking unsafe.

9. Anti-seizure and nerve-pain medications

Examples: gabapentin, phenytoin, carbamazepine

They can affect:

  • Brain signaling
  • Muscle coordination
  • Inner-ear balance

Leading to unsteady movement.

10. Chemotherapy medications

Examples: cisplatin, vincristine

Some can damage nerves involved in balance, resulting in:

  • Dizziness
  • Numbness
  • Difficulty walking

Important safety note

Never stop or change a medication without speaking to your doctor.
If you experience:

  • Dizziness
  • Falls
  • Weakness
  • Unsteady walking

A healthcare provider can:

  • Adjust the dose
  • Switch medications
  • Add treatments or exercises to support balance

Ways to reduce fall risk

  • Review medications regularly with your doctor
  • Stay well hydrated
  • Practice balance and strength exercises
  • Keep living spaces free of tripping hazards
  • Use a cane or walker if recommended
