FAQs
Can I take other drugs at the same time as Synthroid?
Iron supplements (including multivitamins with iron), calcium supplements and antacids can all interfere with Synthroid. Take these 4 hours before or after Synthroid, and check with your doctor about any other medication you take.
If I get pregnant, should I stop taking Synthroid?
Hypothyroidism can lead to complications during pregnancy, including miscarriage, low birth weight, and stillbirth. Don’t stop taking Synthroid if you get pregnant, and talk to your doctor about your Synthroid dose.
