Use caution with other medicines that cause sleepiness — Label Decoder

Official label information

Labeling advises careful observation for CNS depression when gabapentin is used with other sedative drugs, including when morphine is co-administered (gabapentin levels may rise). FDA highlights opioids and benzodiazepines in its breathing warning.

Plain-language explanation

Several medicines or substances can combine to increase sedation, dizziness, slowed breathing, or falls. This includes some sleep aids, anxiety medicines, pain medicines, and allergy products.

What this often means for gabapentin products

“PM” antihistamines, sleep medicines, muscle relaxants, and alcohol belong in the same review. Do not add a sedative to manage gabapentin drowsiness without professional advice.

Ask your pharmacist

Ask for a complete interaction review, including over-the-counter products and supplements.

Caution: Seek urgent help for unusual difficulty waking, slow breathing, or severe confusion.
