Potential Risks of Combining Allegra with Levothyroxine

When Allegra is combined with levothyroxine, there is a potential risk of drug interactions. Both medications can affect the way the other is absorbed and metabolized in the body. This can lead to an increased risk of side effects or reduced effectiveness of one or both medications.

It is important to consult with your healthcare provider before combining Allegra with levothyroxine to ensure that it is safe and appropriate for your individual health condition and medical history. Your doctor may need to adjust the dosages of either medication or monitor you closely for any potential adverse effects.

Some possible side effects of combining Allegra with levothyroxine include changes in heart rate, blood pressure, or thyroid hormone levels. In some cases, this combination can also increase the risk of certain drug interactions or allergic reactions.

Always follow your doctor’s instructions and inform them of all the medications, supplements, or herbal products you are taking to ensure safe and effective treatment.


When Allegra and Levothyroxine are taken together, there is a potential for drug interactions to occur. Allegra, which is an antihistamine, can interfere with the absorption of Levothyroxine, a thyroid hormone replacement medication. This interference can lead to a decrease in the effectiveness of Levothyroxine, potentially resulting in an inadequate treatment of hypothyroidism.

It is important to take Allegra and Levothyroxine at least 4 hours apart to minimize the risk of interaction. Your healthcare provider may also need to adjust the dosage of Levothyroxine to ensure that your thyroid hormone levels remain within the target range while taking Allegra.
