Was recently started in two new medications including lithium. have had tiredness and diarrhea w/ cramps especially after eating. could it be toxicity?

Call your doctor!: Hi M, This is definitely something you should consult with the doc who prescribed the medications. Since you started on the new meds recently, it may take some time for your body to adjust, but weakness and diarrhea are symptoms of toxicity, so better safe than sorry. Please call you doctor immediately! Hope this helpful. Take good care of yourself.
