Practical advice

Timing

Take Levothyroxine on an empty stomach, 60 minutes before breakfast. Acarbose is typically taken with meals. This natural separation works well — thyroid first at wake-up, diabetes medication with breakfast or later meals.

Symptoms to watch for

Monitor blood sugar closely when combining Levothyroxine with Acarbose. Watch for signs of low blood sugar (hypoglycemia): shakiness, sweating, rapid heartbeat, hunger, dizziness, irritability, confusion, or blurred vision. Also monitor for high blood sugar: increased thirst, frequent urination, fatigue, or fruity-smelling breath. Keep fast-acting glucose (juice, glucose tablets) readily available. When to seek emergency help: Severe confusion, loss of consciousness, seizures, or blood sugar below 54 mg/dL that does not respond to treatment. Inform your prescriber about all medications to adjust diabetes medication doses if needed.

What to tell your doctor

No urgent discussion needed, but keep your provider informed. Say: "I take Levothyroxine alongside Acarbose — anything I should know?"
