Can I take Levothyroxine and Coffee together?

Why this happens

Levothyroxine is a sensitive medicine that needs a very specific environment in the stomach to be absorbed properly. Coffee contains compounds that can bind to the medicine or change how quickly it moves through your digestive system, preventing it from entering your bloodstream effectively.

What you should do

You should take your levothyroxine on an empty stomach with a glass of plain water. Wait at least 30 to 60 minutes after taking your tablet before drinking coffee or eating breakfast. To ensure your dose works consistently, try to keep your routine the same every day.

Important precautions

Coffee consumption timing

You must wait at least 30 to 60 minutes after taking levothyroxine before drinking coffee. Coffee significantly reduces the absorption of the medicine, which can lead to unstable thyroid levels.

Food and drink warnings

Coffee and Caffeine

Coffee can significantly reduce the amount of levothyroxine your body absorbs. You should wait at least 30 to 60 minutes after taking your levothyroxine before drinking coffee or tea.

Dairy products (Milk, Yoghurt, Cheese)

Calcium found in dairy products can interfere with the absorption of levothyroxine. It is best to take your medication on an empty stomach and wait at least 30 to 60 minutes before consuming dairy.

Soya products

Soya can interfere with how levothyroxine is absorbed. If you eat a lot of soya, your doctor may need to monitor your hormone levels more closely.

Papaya

There is some evidence that eating large amounts of papaya may reduce the absorption of levothyroxine.

High-fibre foods

A very high-fibre diet (such as large amounts of bran or beans) can reduce the absorption of levothyroxine. If you significantly change your fibre intake, inform your doctor.
