Pharmacist tips for Niva Thyroid
- It's a good idea to take Niva Thyroid first thing in the morning on an empty stomach. Food can affect how much of the medication your body absorbs.
- Make sure to get all your blood work done while taking Niva Thyroid. Your primary care provider will adjust your dose based on your thyroid hormone levels.
- Tell your prescriber if you start to have signs of hyperthyroidism (too much thyroid hormone in your body). This can include feeling shaky, a fast heartbeat, or trouble sleeping. They might check your thyroid hormone levels and lower your Niva Thyroid dose if needed.
- Share a list of all the medication you take with your healthcare team. Niva Thyroid can change how other medications work, and other medications can affect Niva Thyroid too. Your care team can help adjust doses or make a schedule for when to take each medication. This helps prevent any drug interactions.
- If you take cholesterol medications like cholestyramine (Prevalite) or colestipol (Colestid), be sure to take them 4 to 5 hours apart from Niva Thyroid. These cholesterol medications can lower how much thyroid hormone your body absorbs.

Niva Thyroid can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Not for weight loss
- Risk factors: Taking other medications for weight loss
Don't use Niva Thyroid for weight loss. It’s not recommended, safe, or effective for this purpose. Taking high doses of Niva Thyroid can cause serious or life-threatening side effects, especially if you take it with other weight loss medications.
Dangerously low stress hormone levels (adrenal crisis)
- Risk factors: Adrenal insufficiency | Addison's disease
Some people can have low thyroid hormones and low adrenal hormones at the same time. Taking thyroid medications first can make your adrenal hormones drop even more and make you feel unwell. Your prescriber should check your adrenal hormone levels before you start Niva Thyroid. Let them know if you have long-lasting tiredness, muscle weakness, low appetite, stomach pain, or dizziness. These can be signs of adrenal problems.
Worsening diabetes
- Risk factors: Taking diabetes medication
If you have diabetes, taking Niva Thyroid can change how much of your diabetes medications you need. Check your blood sugar levels as directed by your prescriber. Talk to your prescriber if you see that your blood sugar levels are higher than usual. Your prescriber might need to raise the dose of your diabetes medication.
Risk of heart problems with too much medication
- Risk factors: Currently have heart disease or chest pain | Older adults
Taking too much Niva Thyroid can cause heart problems, especially in people who already have heart issues or are at risk. Call your prescriber or get medical care right away if you have a fast or uneven heartbeat, chest pain, or shortness of breath. They can see if you need a lower dose if you have new or worsening heart problems while taking this medication.
Interactions with other medications
Niva Thyroid can change the effects of certain medications. These medications include oral anticoagulants, insulin, and oral diabetes medications.
On the other hand, other medications can have an effect on the levels of Niva Thyroid in your system. This can include certain cholesterol medications and birth control pills.
Before starting Niva Thyroid, talk to your prescriber about all the medications you take. They might need to change your dose or help you plan the best time to take each one during the day. This makes sure your medications work well and lowers the chance of any interaction.
