How Long After Taking Levothyroxine Can You Drink Coffee?

Levothyroxine, also known as Synthroid, is a popular and widely used medication prescribed to those suffering from hypothyroidism or thyroid cancer. It helps to regulate hormone levels in the body, which can then help with symptomatic relief. Many people take levothyroxine and coffee, and though they can usually be taken without issue, it can be detrimental when they are taken close together. As such, it’s important to understand how and when to approach this pairing.

Timeframe for Levothyroxine and Coffee

The general rule of thumb is to wait a minimum of an hour after taking levothyroxine before consuming coffee or coffee-based beverages. This rule also applies to other sources of caffeine such as soda, tea, or energy drinks.

Reasons to Wait with Levothyroxine and Coffee

Coffee and other beverages containing caffeine can inhibit the absorption of levothyroxine, resulting in reduced effectiveness and hormonal imbalances. Additionally, caffeine can increase the risk of developing side effects such as nervousness, tremor, and insomnia while taking the medication.

Warnings when Taking Levothyroxine and Coffee

When taken together, levothyroxine and coffee should be monitored carefully. Take note of any changes in your body’s response to either the medication or the caffeine. If you are having trouble sleeping or notice changes in your energy levels, it could be a sign that you need to make adjustments in your consumption.

It’s also important to follow your doctor’s instructions when taking any medications. If you are unsure about the safety of taking levothyroxine and coffee together, it’s best to err on the side of caution and speak with your doctor about any possible interactions or effects.

Tips for Taking Levothyroxine with Coffee

When possible, try to separate the two as much as you can. In order to ensure that levothyroxine is working properly and to help regulate your body’s hormones, it’s best to take it at least an hour before or after consuming coffee or caffeine.


  • Take Care of Your Body: If you’re feeling overly stressed out or fatigued, avoid drinking coffee. Caffeinated beverages are known to cause jitters or make it hard to relax, which can be especially dangerous when paired with medications.
  • Be Aware of Your Intake: Keep track of how much caffeine you’re taking in. Too much caffeine can have a negative effect on your body, as can combining levothyroxine and caffeine.
  • Talk to Your Doctor: Speak with your doctor to ensure that your current dose of levothyroxine is right for you. Your doctor is the best source of information when it comes to medications and any possible interactions with other substances.


Levothyroxine and coffee can be safely taken together, as long as you give the medication time to take effect before consuming your favorite caffeinated beverages. However, it’s important to speak with your doctor before embarking on any new medications to make sure that any known interactions are discussed and monitored. Ultimately, following this simple rule can help you achieve the best health results from your medication.
