You should talk with your healthcare provider prior to taking Armour® Thyroid (thyroid USP) if you have:
- Adrenal insufficiency
- Any heart problems, including a recent heart attack
- An overactive thyroid (hyperthyroidism)
- Any allergies, including allergies to food, dyes, or preservatives.
Also, let your healthcare provider know if you are:
- Pregnant or thinking of becoming pregnant
Make sure to tell your healthcare provider about any other medicines you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
Warnings and precautions to be aware of prior to taking Armour Thyroid include the following:
- People who do not have documented thyroid problems should never use Armour Thyroid to lose weight. An Armour Thyroid dosage high enough to cause weight loss in such people is often high enough to cause serious or even life-threatening problems. Your healthcare provider cannot diagnose a thyroid problem without blood tests, even though some unscrupulous healthcare providers may do so.
- The medication can make heart problems worse. Therefore, if you have heart problems, your healthcare provider should start you at a low Armour Thyroid dose and slowly increase it. If you notice that the medication is making your heart symptoms worse, let your healthcare provider know right away.
- Armour Thyroid is made from pig thyroid glands. This is important if you have a pork allergy or do not consume pork for religious reasons.
- The medication should not be used to treat goiters or thyroid nodules in people who have a low level of thyroid-stimulating hormone (TSH), as it could cause dangerous side effects. A low TSH level signals that thyroid hormone levels are already high, and adding Armour Thyroid could cause them to increase to a dangerous level. Even if the TSH level is normal, frequent monitoring is required to make sure problems do not develop.
- Armour Thyroid may increase the risk of osteoporosis, particularly if your dose is too high. This is one of the reasons why it is a good reason for your healthcare provider to prescribe a dose of Armour Thyroid that is just enough to return your thyroid hormone levels to normal.
- Sometimes, thyroid problems occur in conjunction with other health problems, such as anemia or diabetes. It is a good idea for your healthcare provider to give you a thorough physical when you are diagnosed with a thyroid problem.
- It often takes the medication several weeks to start working. Try not to get frustrated if you are not feeling better more quickly.
- If you have diabetes, it is a good idea to check your blood sugar more often when starting or stopping Armour Thyroid, or when changing your dose, as the medication can affect your blood sugar.
- Armour Thyroid can potentially interact with many other medications (see Armour Thyroid Drug Interactions).
- Armour Thyroid is considered a pregnancy Category A medication. This means that it is safe for use during pregnancy (see Armour Thyroid and Pregnancy).
- Armour Thyroid does pass through breast milk in humans, although it is not likely to cause problems. However, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking the drug (see Armour Thyroid and Breastfeeding).
