Loss of balance (unsteadiness, dizziness, or feeling wobbly) can be a side effect of several medications, especially those that affect the brain, inner ear, blood pressure, or muscles. Here are 10 common medications (or medication types) that can cause balance problems:
-
Benzodiazepines (e.g., diazepam, lorazepam)
– Can cause drowsiness, slowed reaction time, and poor coordination. -
Opioid pain medications (e.g., morphine, oxycodone, codeine)
– May cause dizziness, sedation, and impaired motor control. -
Antidepressants (especially tricyclics and some SSRIs)
– Can affect blood pressure or brain signaling, leading to unsteadiness. -
Antipsychotics (e.g., haloperidol, risperidone)
– May cause motor control issues and dizziness. -
Blood pressure medications (e.g., beta-blockers, ACE inhibitors)
– Can cause lightheadedness, especially when standing up quickly. -
Diuretics (water pills like furosemide)
– May cause dehydration or electrolyte imbalance, affecting balance. -
Antihistamines (first-generation) (e.g., diphenhydramine/Benadryl)
– Can cause sedation and impaired coordination. -
Anti-seizure medications (e.g., phenytoin, carbamazepine)
– Often affect coordination and gait. -
Muscle relaxants (e.g., cyclobenzaprine, baclofen)
– Can cause weakness, drowsiness, and balance problems. -
Sleep medications (e.g., zolpidem, eszopiclone)
– May cause dizziness or impaired balance, especially at night.
Important notes
-
Balance issues are more likely when starting a medication, increasing the dose, or mixing medications.
-
Teens and adults alike should never stop a medication suddenly without medical advice.
-
If loss of balance is sudden, severe, or comes with symptoms like headache, vision changes, or weakness, it needs medical attention.
