Clinical Effects of Dextromethorphan and QuinidineIn clinical studies, people who took dextromethorphan and quinidine for 12 weeks had fewer involuntary episodes of crying and laughing during the study period than people who took a placebo (a "sugar pill" that does not contain any active ingredients). Some people noticed an improvement within as little as a week. Half of all the people taking dextromethorphan and quinidine did not experience any episodes during the last two weeks of the study.
When and How to Take This MedicationSome general considerations to keep in mind during treatment with dextromethorphan and quinidine include the following:
- This medication comes in capsule form. It is usually taken by mouth once or twice a day.
- Dextromethorphan and quinidine can be taken with or without food. Try taking it with food if it seems to bother your stomach.
- Try to take your doses at the same time each day to keep an even level of the medication in your bloodstream.
- Your healthcare provider may periodically try to take you off this medication. This is because pseudobulbar affect sometimes improves on its own, and you may no longer need the medication.
- For the medication to work properly, it must be taken as prescribed.
