You should avoid drinking milk until at least 4 hours after taking levothyroxine. Dairy products—including milk, cheese and yogurt—contain high calcium levels, which affect how levothyroxine is absorbed into your body.

Drinking milk or eating other calcium-rich foods less than 4 hours before or after taking levothyroxine can reduce the absorption of the drug, lowering its efficacy. Other calcium-rich foods include broccoli, kale, okra and anything containing calcium-fortified flour.

In general, patients are advised to take levothyroxine on an empty stomach and not eat for at least 30-60 minutes after taking it.
