Hi doctor,

I am on Lithium 600 mg per day and Quetiapine 300 mg per day. I would like to know what kind of food, beverages and medicines I should avoid.



Welcome to

Regarding Lithium:

  • Medications for depression (antidepressant drugs) interact with it. Do not take Lithium if you are taking medications for depression.
  • Some of these medications include SSRI (selective serotonin reuptake inhibitors) like Fluoxetine and others in the same group, Sertraline, Amitriptyline, Clomipramine, Imipramine, MAO - monoamine oxidase inhibitors like Phenelzine, Tranylcypromine and others from the same group could interact.
  • Dextromethorphan (a cough syrup) interacts with Lithium.
  • Medications for high blood pressure such as ACE - angiotensin converting enzyme inhibitors, diuretics and calcium channel blockers.
  • Medications for seizure and NSAIDs (nonsteroidal anti-inflammatory drugs) like Diclofenac sodium, Ibuprofen and others from the same group can interact.
  • Avoid eating turkey, alcohol and cheese since it may interact.

Regarding Quetiapine:

  • The SSRI and SNRI (serotonin-norepinephrine reuptake inhibitors) can interact with it. Lithium and Quetiapine is a good combination.
