LABETALOL in Labetalol Injection
may interact with CIMETIDINE in Tagamet Liquid
Cimetidine may increase the amount of labetalol that is absorbed into the body. If this happens, blood levels of labetalol could be increased. This could increase the intended effect of labetalol, meaning that you may experience an even greater decrease in blood pressure. If these drugs are used together, your doctor may want to closely monitor your blood pressure and adjust your labetalol dose if needed. Discuss this potential interaction with your healthcare provider at your next appointment, or sooner if you think you are having problems.
This interaction is poorly documented and is considered moderate in severity.
