Limited data suggest that concurrent administration of antacids may increase the bioavailability of valproic acid. The mechanism of interaction is unknown. In seven healthy volunteers, coadministration of a single 500 mg dose of valproic acid one hour after breakfast and an antacid containing aluminum-magnesium hydroxide (dose equal to 160 mEq of neutralizing capacity) one and three hours after meals and at bedtime on the same day resulted in a mean 12% increase (range 3% to 28%) in the total area under the concentration-time curve (AUC) of valproic acid compared to administration alone. These changes are unlikely to be of clinical importance, and no special precautions appear to be necessary. Equivalent doses of antacids containing either aluminum hydroxide-magnesium trisilicate or calcium carbonate also increased the AUC of valproic acid, but the differences were not statistically significant.

Drug Interaction Classification
The classifications below are a guideline only. The relevance of a particular drug interaction to a specific patient is difficult to determine using this tool alone given the large number of variables that may apply.
| Major | Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. |
| Moderate | Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. |
| Minor | Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan. |
