Hello patti.rod
Welcome to Health Care Mahic

Usually lithium is not reported to cause side effects of lymphadenopathy, so don't worry for lithium dosing. Lamictal is known to causes serious skin side effects and serious hypersensitivity in susceptible individuals and lymphadenopathy may be seen with it. So lymphadenopathy may be probably due to some other cause. Kindly visit a doctor for proper investigation.
Thanks

Hi there, thanks for asking. It is not a common side effect of the medications you mentioned. it is common in infectious mononucleosis to see lymph nodes and they may be seen even several weeks after the beginning of the disease. You can tell her family doctor about it and she should have a full examination to see if her spleen and other organs are normal. She also should not have any hitting to her abdomen. it may happen during sport or any other condition. I wish you and the family a good health.

Hello and welcome to Healthcare Magic. Thanks for your query.

Lymph node enlargement is not a known side effect of lithium and so, is unlikely to be related to the medication. It could be the result of any infection or inflammation in the throat, mouth, etc.

I would advise you to take her to a doctor for a physical examination and evaluation, in oder to determine the cause of the lymph node enlargement. Further treatment will depend on the cause identified.

Wish you all the best.
