Levothyroxine

Levothyroxine is used for low thyroid function. Taking celery seed along with levothyroxine might decrease the effectiveness of levothyroxine. But it is not clear why this interaction might occur, or if it is a big concern.

Some brands that contain levothyroxine include Armour Thyroid, Eltroxin, Estre, Euthyrox, Levo-T, Levothroid, Levoxyl, Synthroid, Unithroid, and others.

Lithium
Interaction Rating: Moderate Be cautious with this combination.
Talk with your health provider.

Celery might have an effect like a water pill or "diuretic." Taking celery might decrease how well the body gets rid of lithium. This could increase how much lithium is in the body and result in serious side effects. Talk with your healthcare provider before using this product if you are taking lithium. Your lithium dose might need to be changed.
