Can Neurontin Tablets Be Crushed?
Yes, Neurontin (gabapentin) tablets can be broken along the scored line, and the capsule contents can be opened and mixed with food or liquid for administration. 1
FDA-Approved Administration Options
The official FDA labeling for Neurontin explicitly addresses tablet manipulation 1:
Scored tablets (600 mg and 800 mg): Patients may break these tablets to administer a half-tablet. The unused half should be taken as the next dose, and any half-tablets not used within several days should be discarded.
Capsules: While the FDA label doesn't explicitly state capsules can be opened, research demonstrates this is a viable option (see below).
Evidence Supporting Capsule Opening
A pharmacokinetic study directly examined whether opening gabapentin capsules affects drug absorption 2. The study found:
- Opening capsules and mixing contents with various foods (applesauce, orange juice, chocolate pudding) did not significantly impair gabapentin absorption
- No statistically significant differences in AUC, Cmax, or tmax were found between intact capsules and opened capsules mixed with food
- The study concluded this is "a viable administration option for patients who are unable to swallow intact capsules" 2
Important Caveats
Do not crush the oral solution formulation - this is already in liquid form and requires no manipulation 1.
For tablets: Only the 600 mg and 800 mg tablets are scored and designed for breaking. The FDA label does not mention crushing tablets into powder, only breaking along the score line 1.
For capsules: Opening and mixing with food is supported by research, with a modest trend toward increased absorption when mixed with protein-containing foods (chocolate pudding showed 26% greater AUC) 2.
