When gabapentin is combined with opioids, which is a potential risk?

• A. Decrease overdose risk
• B. Increase opioid high and overdose risk
• C. No interaction
• D. Safe if monitored with supervision

Answer: (B)

When gabapentin is used with opioids, the risk comes from additive central nervous system depression. Gabapentin and opioids affect the brain in different ways, but they both tend to slow down brain activity. Put together, they can produce more sedation, impair breathing, and dull mental status than either would alone. This combination can raise the chance of overdose, especially in older adults, people with kidney impairment (gabapentin is cleared by the kidneys), or when higher doses or other depressants like alcohol are involved. Because of this, clinicians usually proceed with caution—starting at lower doses, monitoring breathing and alertness closely, and reevaluating whether the combination is truly needed.
