Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription),
and herbal medications that you are taking. Also tell them about any supplements
you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs
can affect the action of many medications, you should let your prescriber know
if you use them. Depending on your specific circumstances, your doctor may want
you to:
- stop taking one of the medications,
- change one of the medications to another,
- change how you are taking one or both of the medications, or
- leave everything as is.
An interaction between two medications does not always mean that you must stop
taking one of them. In many cases, interactions are intended or are managed
by close monitoring. Speak to your doctor about how any drug interactions are
being managed or should be managed.
