Clinicians should carefully consider adjusting levothyroxine therapy in presence of concomitant drugs, such as proton-pump inhibitors, which may reduce levothyroxine bioavailability.Help! I've just been diagnosed and I have no idea what to do! Rules and General Information However, if you are taking levothyroxine (Synthroid) for your underactive thyroid, you should avoid foods that may interfere with absorption of the drug from the gastrointestinal tract. Supplements Certain supplements and food ingredients, including soy, iron supplements (ferrous sulfate), and dietary fiber (psyllium), may reduce the absorption of levothyroxine if consumed too close together. The co-prescription of levothyroxine and potentially interacting drugs results in an increased use of levothyroxine. Consuming grapefruit, grapefruit juice, or even orange juice can reduce the absorption of levothyroxine and reduce its effectiveness. The ensuing study, using 200 mL of grapefruit juice three times daily for only two days, showed a 10 percent decline in the absorption of levothyroxine due to grapefruit consumption. The number of prescriptions and dose of levothyroxine decreased before the potential DDI and increased symmetrically during the period of exposure to potential DDI. In this case, the patient’s use of grapefruit was sufficient to cause a significant decrease in her thyroxine levels, despite an increase in her medication dosage. Design: A retrospective population analysis linking biochemistry and prescription data between 1 January 1993 and 31 December 2012 was used. The incidence rate ratio comparing the TSH trend before and during the period of exposure to potential DDI showed a significant increase of TSH levels during initial exposure to potential DDI, which decreased over time. Objective: The aim of this study was to determine the extent of drug interactions affecting levothyroxine, using study drugs often co-administered to patients on long-term levothyroxine therapy. Overall, 5,426 levothyroxine users (7.5 % of population in HSD) were included in the study. click on the link to read about the interactions with food: Avoid the following: Certain medicines can make levothyroxine less effective if taken at the same time. A quasi-experimental pre-post analysis was carried out using a self-controlled study design, on an intention-to-treat basis. Analysis was limited to individuals aged 18 years and older with at least one levothyroxine prescription from 2002 to 2011 and at least one year of clinical history recorded in HSD. The aim of this study was to analyse the Italian general practice patients with hypothyroidism from 2002-2011, in terms of variation of thyroid-stimulating hormone (TSH) levels, number of levothyroxine prescriptions and dose of levothyroxine before and during potential drug-drug interactions (DDIs).ĭata were extracted from the Italian general practice Health Search CSD Longitudinal Patient Database (HSD). Effects of grapefruit juice on the absorption of levothyroxine Br J Clin Pharmacol. Accordingly, the clinical relevance of the grapefruit juice-levothyroxine interaction is likely to be small. Several drugs may interact with levothyroxine and reduce its bioavailability. Grapefruit juice may slightly delay the absorption of levothyroxine, but it seems to have only a minor effect on its bioavailability.
