Sinemet Interactions Checker
The timing of meals relative to your oral levothyroxine dose can affect the absorption of the medication. Therefore, levothyroxine should be taken on a consistent schedule with regard to time of day and relation to meals to avoid large fluctuations in blood levels, which may alter its effects. In addition, absorption of levothyroxine may be decreased and/or delayed by foods such as soybean flour, cotton seed meal, walnuts, dietary fiber, calcium, calcium fortified juices and grapefruit or grapefruit juice. These foods should be avoided within several hours of dosing if possible. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Thyroid hormones, including SYNTHROID, either alone or with other therapeutic agents, should not be used for the treatment of obesity or for weight loss. In euthyroid patients, doses within the range of daily hormonal requirements are ineffective for weight reduction. Larger doses may produce serious or even life-threatening manifestations of toxicity, particularly when given in association with sympathomimetic amines such as those used for their anorectic effects. Sometimes drug interactions cannot be avoided because both medicines may be very important to your treatment. In the case of levothyroxine, you may need more frequent testing of thyroid stimulating hormone and T4 levels when other medications are added or removed from your treatment regimen. After another drug has been added to or removed from your regimen, you should report worsening of any disease symptoms or medication side effects to your doctor.
Some mixtures of medications can lead to serious and even fatal consequences.
