The most accurate way to get the correct information about drug/drug or drug/food interactions is to discuss your concerns with your doctor or pharmacist and have handy a complete list of the medications, prescribed and over the counter with you.

I'll just add that one should NEVER assume that over-the-counter (OTC) drugs or so-called "natural remedies" or "herbal" or "homeopathic" remedies are automatically safe to combine with prescription medications.
Remember: if or when herbal remedies work, it is because they are doing something similar to what the prescription drugs are doing and typically are influencing the body or brain chemistry in the same way.
St. John's Wort is a case in point. It has a mild serotonin boosting effect. When used in combination with SSRI medications, it can result in a toxic reaction sometimes called "serotonin syndrome", which is basically an overdose.
If you are taking prescribed medications, NEVER augment these with OTC or "herbal" medications without first checking with your doctor and/or pharmacist.
