Before taking Seroquel XR (Quetiapine) speak with your doctor regarding known allergies as there are ingredients that induce an allergic reaction. Speak with your doctor about prior medical conditions relating to liver disease, low white blood cell count, thyroid problems, heart disease, high blood pressure, or difficulty urinating. Disclose any medications and supplements to ensure there are no interactions while taking Seroquel XR.
In some cases your doctor may instruct you to start at a low dose and slowly increase the dose to an optimal level to treat your condition. It is important that you do not change the dose during this time and follow the doctors explicit instructions to ensure there are no side effects. You should continue to take this medication even if you feel better, and do not stop taking Seroquel XR without instruction from your doctor.
You may feel dizzy, drowsy or have blurred vision while taking Seroquel XR. Do not operate heavy machinery or drive a vehicle until you know it is safe to do so. Avoid alcohol and cannabis as they can exasperate the dizzying effects. Speak with your doctor about the acceptable limits of these substances.
You may sweat less while taking Seroquel XR and could put you at risk for heat stroke. Avoid strenuous physical activity, seek shade if you become overheated, and stay hydrated to avoid heat stroke. If you develop a fever, or have headaches and dizzy spells that don't away, speak with your doctor right away for medical treatment.
There is a risk of developing irregular or altered heart beat (QT prolongation) while taking Seroquel XR. If you have reduced levels of potassium or magnesium there could also be a risk of developing QT prolongation.
