Call your pharmacist and ask them some questions about these meds. They are a wealth of information because they know so much about medications and how they work and side effects that are possible.

Continue to call your pdoc until you get a response .

Here is the top side effects I found on WebMd :

Dizziness, lightheadedness, drowsiness, nausea, vomiting, tiredness, excess saliva/drooling, blurred vision, weight gain, constipation, headache, and trouble sleeping may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
