Can Synthroid (levothyroxine) be crushed?
Also searched as Synthroid, Levo-T, Unithroid · Immediate-release tablet
FDA labeling for Synthroid describes crushing the tablet and suspending it in a small amount of water for pediatric patients who cannot swallow intact tablets, with the suspension given immediately and not stored. The label warns not to mix it with foods that decrease absorption, such as soybean-based formula. Adults should confirm the method for their exact product with a pharmacist.
Ask the pharmacist what foods and liquids to avoid mixing with crushed levothyroxine, whether the label's pediatric instructions apply to the person taking it, and whether a liquid product would be simpler.
Confirm with your pharmacist before changing how any medication is taken. This page never provides dosing guidance.
- Match the generic or brand name and strength on the prescription label.
- Match the exact formulation, especially ER, XR, XL, SR, CR, DR, or EC.
- Use the manufacturer or NDC and imprint as supporting identifiers, then confirm with the pharmacist.
Do not use color or shape alone. FDA guidance notes that approved generic pills can look different while containing the same medicine.
