What Is Diclofenac (Voltaren)?

Potential Medication Interactions

Diclofenac does not seem to have serious medication interactions with many medicines. However, it may trigger mild interactions with more than 350 medications. Due to this, patients may want to write down all of the medications and supplements they currently take. Sharing this list with their doctor can be quite important. Medications of note appear to include heart or blood pressure medications. Some doctors may even ask about diuretics when they are considering prescribing this medication.

Blood thinners may also cause an interaction with diclofenac. This possibility may be magnified if patients also have a clotting disorder. Patients may not be able to take another NSAID at the same time as this one, since they may also result in an interaction. Doctors also need to monitor a patient's dose of this medication, so patients may need to tell them if they take it in another form already.
