Some products that may interact with this drug are: thioridazine, other drugs that can cause bleeding/bruising (including antiplatelet drugs such as clopidogrel, NSAIDs such as ibuprofen/naproxen, "blood thinners" such as dabigatran/warfarin).

Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.
