Consumer:

Consumer information for this minor interaction is not currently available. Some minor drug interactions may not be clinically relevant in all patients. Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.

Professional:

Antacids and some oral aluminum, calcium, or magnesium containing preparations may increase the absorption of levodopa. The mechanisms may be related to increased gastric pH and/or decreased gastric emptying time, resulting in less gastric degradation of levodopa and more levodopa absorption from the small intestine. This effect may be beneficial in some patients, but also difficult to predict and monitor. For most patients, this interaction is not clinically significant and no specific intervention would be required. Dosing intervals could be spaced by at least 2 hours if it is preferred to avoid this interaction.
