How soon after taking levothyroxine can I take omeprazole?
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 ± 0.66mU/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.
Evidence
Unfortunately, as mentioned, there is a known drug interaction between omeprazole (and other similar medications) and thyroid hormone drugs. If you have been taking this medication a different way or time, you should continue to take it in that manner. The most important part of levothyroxine administration is taking it the exact same way and time everyday.
Many individuals are curious about the potential benefits of combining these medications for their health. Levothyroxine 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.
Drug and Breastfeeding Interactions
Always consult your healthcare provider before starting or stopping any medication. In animal models, decreased postpartum offspring growth rates were observed when this drug was administered during late gestation and throughout lactation at oral doses of at least 138 mg/kg/day and IV doses of 3.2 mg/kg/day. Prilosec works by decreasing the production of stomach acid, which can help alleviate symptoms of acid reflux and heartburn. This can provide significant relief for individuals suffering from these conditions. First, an antacid like calcium carbonate (Tums) is safe to take with thyroid hormones, as long as you are taking it at least 4 hours after your thyroid hormone dose. Also, over the counter famotidine (Pepcid) is a safer option than PPIs, if separated by 12 hours or more from thyroid hormones.
This decreases the acidity of your stomach contents (which is why it can interact with thyroid prescription products). While this interaction is unlikely to cause significant problems, it could intensify side effects or reduce the effectiveness of one or both medications. Monitoring for changes in symptoms and your condition is recommended, and adjustments may be made if needed to manage any increased or more pronounced side effects. These drugs, generally, should not be used together simultaneously due to the high risk of severe adverse effects. Combining these medications can lead to dangerous health outcomes and should be strictly avoided unless otherwise instructed by your provider.
In 2003, omeprazole became available without a prescription to treat heartburn. When treating heartburn, omeprazole should not be taken for more than 14 days at a time. As stated above regarding the levothyroxine dosing, the main concern is taking the levothyroxine the exact same way everydayto avoid potential for swings in thyroid hormone levels in the blood. In addition, you generally need to take calcium and other metal containing multivitamins at least two hours before or four hours after taking levothyroxine as they can greatly affect the levels of levothyroxine.
It provides fast relief from symptoms and helps prevent the recurrence of conditions like GERD and ulcers. Prilosec is also available over-the-counter, making it easily accessible for individuals seeking relief from stomach-related problems.

Administer levothyroxine 4 hours before or after drugs synthroid tests that are known to decrease absorption . Monitor TSH levels closely and adjust levothyroxine doses as necessary during concomitant use . Because omeprazole reduces the amount of acid produced by your stomach, it results in decreased absorption of levothyroxine.
Proton Pump Inhibitors
Levothyroxine should be taken once a day in the morning on an empty stomach (30 to 60 minutes before eating breakfast). Taking it on an empty stomach results in the best absorption from the intestine. The number one concern in dosing these medications is the levothyroxine as it has the narrowest therapeutic index and can be the easiest medication to affect by changing/adding other medications.
Concomitant use of levothyroxine and a proton pump inhibitor may cause clinically significant increases in TSH levels. Combining Levothyroxine and Prilosec can have a significant impact on health results. Levothyroxine is a medication commonly used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone.
