Diabetes and thyroid meds?

I checked Thyroid meds for potential interactions with metformin and insulin and they have a moderate interaction E.g random check:

Interactions between your drugs
Moderate
insulin levothyroxine
Applies to: insulin, Synthroid (levothyroxine)

Levothyroxine may interfere with blood glucose control and reduce the effectiveness of insulin and other diabetic medications. Monitor your blood sugar levels closely. You may need a dose adjustment of your diabetic medications during and after treatment with levothyroxine. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Switch to professional interaction data

Moderate
insulin metFORMIN
Applies to: insulin, metformin

Using metFORMIN together with insulin can increase the risk of hypoglycemia, or low blood sugar. You may need a dose adjustment or more frequent monitoring of your blood sugar to safely use both medications. Let your doctor know if you experience hypoglycemia during treatment. Symptoms of hypoglycemia include headache, dizziness, drowsiness, nervousness, confusion, tremor, nausea, hunger, weakness, perspiration, palpitation, and rapid heartbeat. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
