Applies to:erythromycin/sulfisoxazole and Milk of Magnesia (magnesium hydroxide)
Limited data suggest that concurrent administration of antacids may prolong the elimination half-life of erythromycin. The mechanism of interaction is unknown. In eight healthy volunteers, administration of erythromycin stearate 500 mg followed immediately with 30 mL of antacid (aluminum hydroxide/magnesium hydroxide/simethicone 200 mg/200 mg/20 mg per 5 mL) resulted in a doubling of the mean elimination rate constant compared to administration of the erythromycin stearate alone. Coadministration with antacid had no effect on the peak serum concentration (Cmax), total area under the concentration-time curve (AUC), or time to peak concentration (Tmax) of erythromycin. These changes are unlikely to be of clinical importance, and no special precautions appear to be necessary.

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. |
