I am bumping your post up. Here
is what I found on the possible side effects of Diovan HCT:
You may experience dizziness, lightheadedness, blurred vision, or tiredness as your body adjusts to the medication. You may also experience diarrhea, dry mouth, nausea, vomiting, or cough. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.
