Use of proton pump inhibitors and levothyroxine

Of 887 patients who had been on a stable levothyroxine dose for at least 2 years prior to initiation of a proton pump inhibitor, 5.6% had a 5 milliunit/L or greater increase in TSH. When these two medications are taken together, there can be potential interactions that affect the absorption and effectiveness of both drugs. Levothyroxine, for example, may have reduced absorption when taken with Prilosec, leading to decreased thyroid hormone levels in the body. This can result in symptoms of hypothyroidism such as fatigue, weight gain, and depression. Prilosec, also known as omeprazole, is a proton pump inhibitor (PPI) medication used to treat conditions such as gastroesophageal reflux disease (GERD), ulcers, and inflammation of the esophagus. Prilosec works by reducing the production of stomach acid, which helps alleviate symptoms like heartburn, acid reflux, and indigestion.

Omeprazole and pantoprazole are proton pump inhibitors, most commonly used for gastroesophageal reflux disease (GERD), ulcers, and other gastric hypersecretory conditions. Each of the included studies showed an increase in TSH levels following LT4 and PPI consumption and in the majority of these, the increase was statistically significant. This effect could be much evident in subjects in whom LT4 absorption is already impaired for other reasons. However, this finding should be interpreted with caution due to the limited number of studies with relatively short follow-up period and lack of robust statistical evidence. Well-designed large studies are needed in order to further better clarify the interfering role of PPI on LT4 intestinal absorption. Regarding the quality assessment, six out of seven studies were considered at low risk of bias,25–28,31,38 while one37 was considered at moderate risk because of measurement of outcomes.

Findings from Studies with LT4 Tablet Formulation

There was a considerable heterogeneity among the included studies in design, sample size, inclusion and exclusion criteria, treatment regimen, and baseline demographics. Each of the included studies showed an increase in TSH levels following LT4 and PPI consumption, and in the majority of these, the increase was statistically significant. I want to point out that moststudies have researched the effects of PPIs and levothyroxine specifically, not necessarily Cytomel and Nature-Throid.

Therapeutic duplication warnings are only returned when drugs within the same group exceed the recommended therapeutic duplication maximum. Improves overall quality of life by alleviating discomfort caused by acid-related conditions. Omeprazole and pantoprazole should be given on an empty stomach 60 minutes before the first meal of the day. This section collects any data citations, data availability statements, or supplementary materials included in this article. If you do experience frequent heartburn or GI symptoms, it might be a good idea to schedule an appointment and follow up with your physician.

Prilosec is designed to provide long-lasting relief from stomach-related issues, allowing individuals to experience symptom reduction over an extended period of time. One of the main advantages of using Prilosec is its effectiveness in treating various digestive issues.

Interactions between your drugs

• This can provide significant relief for individuals suffering from these conditions.
• Even though previous studies suggest that PPIs affect levothyroxine absorption, this small study shows that the absorption of liquid levothyroxine is not affected by PPIs.
• Proton pump inhibitors, when taken consistently, have a long duration of action.
• Ultimately, the effectiveness of taking both Levothyroxine and Prilosec together will depend on your individual health condition and treatment goals.

Many individuals are curious about the potential benefits of combining these medications for their health. Levothyroxine walnuts synthroid is commonly prescribed to treat hypothyroidism, while Prilosec is used to reduce stomach acid and treat conditions like gastroesophageal reflux disease (GERD). When taken together, these medications can complement each other’s effects and improve overall well-being. Even though previous studies suggest that PPIs affect levothyroxine absorption, this small study shows that the absorption of liquid levothyroxine is not affected by PPIs. This study suggests that liquid levothyroxine may be a better treatment option for patients with hypothyroidism that are also taking medications such as PPIs. This may be especially important for patients who are not taking PPIs on a regular basis, but on and off, as it is often the case, and in this way, avoid swings of the thyroid levels.

• In 2003, omeprazole became available without a prescription to treat heartburn.
• They can alter the stomach acid for well over 24 hours after dosing (which is why they are generally dosed on daily).
• A small change in absorption may lead to decreased thyroid levels and you beginning to feel the effects of hypothyroidism.
• One brand of levothyroxine, Tirosint, is liquid that can be taken in a gelcap or as a liquid (Tirosint-SOL).
• Its effects of decreasing stomach acid begin within an hour and last as long as 72 hours.

Drug and Pregnancy Interactions

You may have even heard that you should not take your levothyroxine (Euthyrox, Levothroid, Levoxyl, Synthroid, Unithroid) with coffee. Just be sure to take the levothyroxine consistently at the same time and the same way. The results were supplemented by a manual search of the bibliographies of the shortlisted review and original study articles.

A. There is a strong likelihood that the PPI (proton pump inhibitor) you are taking for acid reflux is interfering with absorption of your thyroid medicine (Clinical Drug Investigation, March 2015). One brand of levothyroxine, Tirosint, is liquid that can be taken in a gelcap or as a liquid (Tirosint-SOL). Since the liquid form does not need to be dissolved, then the effect of PPIs on levothyroxine absorption should be minimal.

• Prilosec, also known as omeprazole, is a proton pump inhibitor (PPI) medication used to treat conditions such as gastroesophageal reflux disease (GERD), ulcers, and inflammation of the esophagus.
• The aim of this study was to assess the effect of concomitant use of levothyroxine (LT4) and proton pump inhibitors (PPIs) on thyroid-stimulating hormone (TSH) levels in patients with primary hypothyroidism.
• Both are usually taken once a day, first thing in the morning on an empty stomach.
• Study quality was assessed with the Newcastle–Ottawa quality assessment scale for observational studies and the Risk Of Bias In Non-randomized Studies – of Interventions (ROBINS-I) tool was used.

Changing administration habits can put your thyroid hormones off and you may require a dosing adjustment. Saraceno et al.37 carried out a crossover study in 15 patients on LT4, 6 of them on replacement therapy and 9 on TSH-suppressive therapy, who were receiving PPI. Serum levels of TSH were lower under the oral solution compared with the tablet both in the replacement group (1.63 ± 0.66 mU/l vs. 2.77 ± 2.05 mU/l) and in the suppressive group (0.12 ± 0.12 mU/l vs.1.15 ± 1.85 mU/l). There is a known drug interaction between levothyroxine and omeprazole, but the timing of when you take the two medicines is not relevant. If you need to be on a course of omeprazole while taking levothyroxine, your doctor may order more frequent laboratory testing to confirm you are absorbing enough levothyroxine.
