Now, some patients will start to feel better in a fairly short period of time. However, Sally actually start to feel worse! So she went back to her doctor because she was feeling worse. The thyroid function is low and the patient is taking thyroid replacement.
Heck, their TSH is even coming down! This is where many patients really start to get agitated, frustrated, angry, and depressed. I wonder how many prescriptions for Zoloft have been written because of this exact scenario….
By the time the patient finds our clinic they are often extremely tired, frustrated, and fatigued. They thought they had a thyroid problem and were so excited to start a solution. Yet, they occasionally start feeling worse. Let me tell you, I often get an ear full! No worries, it is why we are here! They will tell me their story while I listen with a bit of a smile. When they tell me that they started feeling worse when they started their thyroid medicine I have the pleasure of educating them about how thyroid hormones work and what is going on when you take T4 only medications.
There is often a lightbulb that goes off once I explain why. If you want a more detailed explanation of what follows read my post on The Mismanaged Thyroid here. This population requires careful and consistent dosing in order to suppress TSH as a way to prevent cancer recurrence. If you've had thyroid cancer, talk to your healthcare provider about the pros and cons of taking generics. For several years, a liquid, softgel capsule form of levothyroxine has been available in the United States under the brand name Tirosint.
It was designed primarily as a hypoallergenic, specialized form of levothyroxine for people who have digestive or intestinal issues, difficulties with the absorption of thyroid medication, or allergies to the fillers and binders in the tablet formulations of levothyroxine drugs.
A study that was presented at the American Thyroid Association conference compared the effectiveness of levothyroxine tablets, the usual formulation, and softgels in patients who had a total thyroidectomy for a multinodular goiter. None of the patients had any issues with absorption. Around half the patients studied were given levothyroxine tablets, and the other half received the softgel capsules at the same dosage, starting immediately after the thyroid surgery.
At both six and 12 weeks, the patients taking the softgel capsules had significantly lower TSH levels and at both measurement points, the number of patients who had elevated TSH levels above 3. The researchers concluded that even in patients who had no malabsorption or digestive issues, the softgel formulation was more effective. Tirosint doesn't contain sugars, dyes, alcohol, wheat starch gluten , lactose, acacia , or any other additives or fillers that are commonly used to make levothyroxine tablets.
The only ingredients in the capsules are levothyroxine, gelatin, glycerin, and water, which are not likely to interfere with the absorption or cause allergies. There aren't currently any generic formulations available. If you're trying to save on costs and you want to try switching from brand name levothyroxine to a generic version, talk to your healthcare provider.
You may need some more frequent monitoring of your TSH levels at first until he or she can make sure that you're staying where you need to be and not having symptoms. Consider the tips about minimizing potency fluctuations mentioned above as well.
In cases where due to cost, insurance, or your HMO, you're forced to take generic levothyroxine and can't guarantee that you're getting refills from the same generic manufacturer, you should monitor your symptoms carefully after each refill. If you have symptoms, talk to your healthcare provider about having your thyroid levels rechecked to ensure that you aren't experiencing fluctuations due to different product potency. You may be finding it challenging to reach your targeted or optimal thyroid test levels and to resolve your continuing symptoms of hypothyroidism, so you want to try a brand name like Synthroid.
Or maybe you've had thyroid cancer or you're sensitive to inactive ingredients and you want to look into trying Tirosint. Because of its status as a specialty drug for a limited audience, and because Tirosint is significantly more expensive than other brands of levothyroxine or generic tablets, it has to date not been widely used for hypothyroidism treatment in the United States.
This means that your health insurance company or HMO may not be willing to pay for it, or other brand names, for that matter. If this is the case, your healthcare provider may need to write a letter to explain to your insurance provider why you need the brand name. If you do end up having to pay the difference out-of-pocket, check into any discounts you can get online, such as GoodRx.
Also look to see if you can find any coupons or discount programs from the manufacturers of the brand name you're looking into. The ATA recommends that you take the same medication, whether generic or brand name, throughout your treatment to avoid potency variations.
If you've tried generics and found they simply don't work as well for you as a particular brand name of levothyroxine does, ask your healthcare provider to write your prescription with the special designation "DAW" on your prescription, which means "dispense as written," along with "no generic substitution.
Yeah, you'll look weird. Just try it. The bump that moves is the cartilage often called the Adam's apple, and underneath that is where your thyroid sits.
Your thyroid is basically the on-board computer for your body—the hormones it regulates affect almost every system and as long as it's doing its job you forget it's even there.
But when it's not working properly? Hell, meet hand basket. When the thyroid doesn't produce enough hormone, it's called hypothyroidism, which can lead to symptoms like weight gain , fatigue, irregular periods, or a slowed heart rate.
There's also hyperthyroidism , when the body produces too much thyroid hormone, but that's a whole different issue. The most popular medication used to to treat hypothyroidism and bump up those hormone levels: Synthroid.
Synthroid is the brand name for levothyroxine sodium, a synthetic thyroid hormone pill. Like any medication, Synthroid can have side effects, but for most people, the drug just makes them feel awesome again, Goldfarb says. Although there are about 1 percent of patients that won't respond to Synthroid at all and will need other treatment, the vast majority of people on it feel remarkably better within six weeks of starting it, she adds.
To make sure your dosage isn't screwy or you're not part of that small percentage that doesn't mesh well with this med , here are some side effects of Synthroid to watch out for:. Coffee may decrease the amount of Synthroid that your body absorbs. This means that if you drink coffee with your dose of Synthroid, you may not be getting the full amount of Synthroid in your dose.
In this case, Synthroid may not work as well as usual for you. Your doctor may recommend that you take your doses of Synthroid at different times than when you drink coffee. Grapefruit and grapefruit juice may both interact with Synthroid, decreasing the level of Synthroid in your body.
If your Synthroid level is decreased, the drug may not work as well as usual for you. Your doctor may recommend that you take your doses of Synthroid at different times than when you consume grapefruit. Or they may recommend that you avoid the fruit altogether. Soybeans and soybean flour may bind to Synthroid inside your stomach and stop your body from absorbing the drug properly. If you eat soybeans or soybean flour, your doctor may increase your dosage of Synthroid.
Doing this will help to make sure that you have enough of the medication in your system. Your doctor may also order certain blood tests more often than usual to monitor your thyroid. Synthroid may be affected by cottonseed meal. This product may bind to Synthroid inside your stomach and lower the amount of Synthroid your body absorbs. In this case, you may not have enough Synthroid in your body to treat your condition.
If you eat cottonseed meal, your doctor may increase your dosage of Synthroid. Or they may recommend that you decrease the amount of cottonseed meal in your diet.
Your doctor may also check certain blood tests more often than usual to monitor your thyroid. Walnuts can bind to Synthroid inside your stomach and lower the amount of Synthroid that your body absorbs.
Or they may recommend that you eat other nuts instead. If you do eat walnuts, your doctor may order certain blood tests more often than usual to monitor your thyroid. Dietary fiber may bind to Synthroid inside your stomach, which can lower the amount of Synthroid your body absorbs. Dietary fiber is fiber that you consume from eating certain foods.
Your doctor may also recommend that you decrease your fiber intake. And they may order certain blood tests more often than usual to monitor your thyroid. Synthroid may affect certain blood tests, such as those used to check your thyroid hormone levels. In addition, a supplement called biotin may interact with labs that are used to check thyroid hormone levels. Both of these interactions are described below. Biotin supplements may affect the blood tests used to check thyroid hormone levels.
In fact, biotin may cause certain blood tests to show a high level of thyroid hormone in your body. But this interaction is just between the blood test and the biotin supplement. If you take biotin, your doctor may have you take less of the supplement for a few days before you have labs to check your thyroid.
Or your doctor may recommend that you stop taking the biotin supplement before your labs. This is done to be sure that your levels are within a normal range. But keep in mind that Synthroid is a man-made form of the natural thyroid hormone called T4. This means that if you take the drug before having blood work, your T4 level may be falsely elevated. Before having blood tests to check your thyroid, ask your doctor if you should take your Synthroid doses as usual. Your doctor will recommend when you should take your Synthroid dose in relation to when your labs will be done.
Synthroid comes as tablets that are taken by mouth. Synthroid should be taken once daily on an empty stomach. In some cases, your doctor may discuss with you how to take Synthroid at night.
You should take Synthroid on an empty stomach without food. If you do eat something, and you forget to take Synthroid, call your doctor or pharmacist.
This length of time may depend on the type of food you ate and whether you took any other medications. You may need to wait 4 hours to take your Synthroid after eating. If you have questions about when to take Synthroid around meals, talk with your doctor or pharmacist. Yes, you can crush, split, or chew Synthroid tablets. For example, to give the drug to children or infants, Synthroid tablets can be crushed and dissolved in 1 to 2 teaspoons 5 to 10 mL of water.
This is because Synthroid should be taken on an empty stomach. Synthroid may also be used off-label for other conditions. Synthroid is approved to treat hypothyroidism. With this condition, you can have symptoms such as tiredness and weight gain. You may also have muscle weakness and constipation. Thyroid hormones are very important to your health because they regulate your metabolism all of the chemical reactions in your body.
The two main thyroid hormones in your body are called T3 and T4. Synthroid is a man-made form of T4, and it works by replacing T4 in your body. Your body then uses T4 to make T3.
These different types of hypothyroidism have different causes. However, Synthroid works the same way no matter the cause of the condition. Despite this lack of clinical trials, levothyroxine the active drug in Synthroid is recommended as the primary treatment for hypothyroidism. In , the American Thyroid Association released guidelines showing the best treatments for hypothyroidism.
These guidelines state that products that contain levothyroxine should be used as the standard treatment for hypothyroidism. The years of use have shown that levothyroxine reduces symptoms of hypothyroidism in most people. In addition, levothyroxine treatment has been shown to be safe and without many serious side effects.
T4 was first recognized in the human body in , and a man-made form of it called levothyroxine was first made in In , new laws were created by the FDA. Synthroid is approved to suppress decrease levels of thyroid stimulating hormone TSH. TSH stimulates your thyroid to make thyroid hormones.
The two main thyroid hormones in your body are T3 and T4. In addition, TSH is responsible for growth of cells in your thyroid gland, including growth of cancerous cells. By decreasing your TSH level, Synthroid can help decrease the growth of certain types of thyroid cancer.
Normally, when your thyroid hormone levels are low, your body makes TSH. This signals your thyroid to make more thyroid hormones. With a lower TSH level, growth of cancer in your thyroid may decrease.
When Synthroid is used for TSH suppression, the drug is meant to be used along with surgery and radioactive iodine treatment. According to the American Thyroid Association , TSH suppression is recommended in some people with high-risk forms of thyroid cancer. Levothyroxine is the recommended drug to use alongside surgery and radioactive iodine treatment. However, levothyroxine is considered the recommended drug for this use.
In addition to the uses listed above, Synthroid may be used off-label for other purposes. And you may wonder if Synthroid is used for certain other conditions.
With this condition, you have increased levels of thyroid hormones in your body. The two main thyroid hormones are T3 and T4. Instead, Synthroid is FDA-approved to treat hypothyroidism , which is the opposite of hyperthyroidism. With hypothyroidism, you have low levels of thyroid hormone. Synthroid is a man-made form of T4. It replaces or adds to your natural thyroid hormones, which helps your body to have the right amount of T4.
Your body then uses the T4 to make T3. This raises your risk of serious side effects, such as tremors, anxiety, and irregular heart rate. If you have hyperthyroidism, talk with your doctor about appropriate treatment options for your condition.
In some cases, children may need to take Synthroid for certain problems affecting their thyroid. Below, we describe approved uses of Synthroid for children. From birth, some children may not be able to make enough thyroid hormones. This condition is called congenital hypothyroidism.
Usually, for congenital hypothyroidism, a child will take Synthroid for their entire life. Synthroid works by replacing T4, one of the main thyroid hormones. And their body then uses T4 to make T3, which is the other main thyroid hormone. Children may also acquire develop hypothyroidism during their childhood. This may occur because of changes in their thyroid or pituitary. The pituitary tells the thyroid to make thyroid hormones. In some cases, your doctor may recommend that you take other medications with Synthroid.
Below, we describe some supplements that your doctor may recommend. However, before starting any of these supplements, be sure to talk with your doctor. Vitamin D plays a role in how your immune system functions. And because some thyroid conditions are related to your immune system, people with these conditions may have low vitamin D levels. If you have hypothyroidism, your doctor may order blood tests to check your vitamin D level.
And your doctor may recommend that you take a vitamin D supplement if your levels are low. For some people, increasing vitamin D level may help decrease symptoms of their thyroid condition. It makes you feel sleepy when it gets dark outside. One study showed that melatonin may increase your levels of T4. T4 is one of the main thyroid hormones in your body, which Synthroid is used to replace or add to. And the study showed that melatonin may also decrease feelings of anxiety and depression.
In some cases, your doctor may recommend that you take a melatonin supplement along with Synthroid. But keep in mind that melatonin may affect your thyroid hormone levels. Because of this, your doctor may check your thyroid hormone levels when you first start taking melatonin.
Sometimes hypothyroidism may cause problems with your intestines. This may happen because decreased thyroid function is linked to having too much bacteria in your small intestine. And having large amounts of bacteria in your intestine may result in certain problems, such as diarrhea. Taking a probiotic may help to decrease harmful bacteria and increase helpful bacteria in your gut.
Synthroid is a man-made form of a natural thyroid hormone called T4. Below, we describe how Synthroid works for each of these uses. The main thyroid hormones in your body are T3 and T4. And your body then uses T4 to make T3. Synthroid helps to bring your thyroid hormone levels back to a normal range. And it also helps reduce your symptoms of hypothyroidism. Synthroid is used to suppress lower TSH levels in people with thyrotropin-dependent well-differentiated thyroid cancer.
TSH stimulates your thyroid to make more thyroid hormones. In addition, TSH is responsible for cell growth in your thyroid gland. This includes growth of both healthy cells and cancerous cells in the gland. The drug usually has its maximum effect in your body about 4 to 6 weeks after you start taking it. If you have thyroid-related symptoms, you may notice your symptoms are decreasing within 4 to 6 weeks after starting the drug.
After 4 to 6 weeks of treatment, your doctor will check blood tests to monitor your thyroid.
