Can Thyroid Medicine Cause Hot Flashes

Hyperthyroidism And Graves Disease

Treating Hot Flashes Caused by Hormone Therapy

Hyperthyroidism occurs when the thyroid gland produces too much thyroid hormone. This disorder occurs in about 1% of all Americans and affects women much more often than men. In its mildest form, hyperthyroidism may not cause noticeable symptoms however, in some patients, excess thyroid hormone and the resulting effects on the body can have significant consequences.

How Should I Take Levothyroxine

Take levothyroxine exactly as it was prescribed for you. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Levothyroxine oral is taken by mouth. The injection is given as an infusion into a vein. Levothyroxine is usually given by injection only if you are unable to take the medicine by mouth.

Levothyroxine oral works best if you take it on an empty stomach, 30 to 60 minutes before breakfast. Follow your doctor’s dosing instructions and try to take the medicine at the same time each day.

Swallow the tablet or capsule whole, with a full glass of water. The tablet may dissolve very quickly and could swell in your throat.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device .

Levothyroxine doses are based on weight in children. Your child’s dose needs may change if the child gains or loses weight.

It may take several weeks before your body starts to respond to levothyroxine. Keep using this medicine even if you feel well. You may need to use this medicine for the rest of your life.

You may need frequent medical tests. Tell any doctor, dentist, or surgeon who treats you that you are using this medicine.

Store at room temperature away from moisture and heat.

Do not share this medicine with another person, even if they have the same symptoms you have.

Whats Special About University Of Michigans Treatment Of Graves Disease

UM is one of the few places in the country that has a multidisciplinary group dedicated to the treatment of patients with Graves disease. UMs multidisciplinary group consists of endocrinologists, endocrine surgeons, ophthalmologists, nuclear medicine physicians, rheumatologists and psychiatric professionals. Our group sees Graves disease patients from around the country and is involved with one of the most well-known national organizations concentrating on helping patients and families coping with Graves disease and Graves eye disease. Our group routinely publishes papers with new research results on Graves disease.

The ophthalmologists in our group specialize in the treatment of Graves eye disease which can require complex management. Most ophthalmologists have little experience treating patients with Graves disease and Graves eye disease. For those patients with Graves eye disease, it is the severity of the eye disease which drives the selection of the type of treatment for hyperthyroidism if these two problems occur together.

While those patients with no Graves eye disease or only mild eye disease may be candidates for any of the three types of treatments for hyperthyroidism, those who have moderate to severe eye disease are often referred for surgical thyroidectomy as RAI has a higher chance of worsening the eye disease than surgery does.

Symptoms Unique To Menopause

No one really wants to experience many of menopauses symptoms, but if the state of your thyroid is any concern, there are symptoms unique to menopause that should give you some relief about any further medical issues.

Vaginal Dryness

Painful Intercourse

On the same note, because menopause can cause vaginal dryness, it can lead to painful intercourse as well. The increased sensitivity and loss of lubrication can make even the slightest friction feel highly uncomfortable, and although the thyroid hormones have a wide-reaching effect, menopause more specifically affects estrogen and its ability to keep skin smooth and elastic.

Mood Swings

As the name suggests, mood swings are rapid changes in mood that can come unexpectedly. Something might suddenly make you inexplicably angry, or youll find yourself bawling your eyes out for no reason. This is caused by fluctuations in estrogen similar to puberty, just in reverse, and its rarely associated with a thyroid issue.

Bone Density Decrease

Just as the loss of muscle mass is normal as we age, loss of bone mass can happen as well. Menopause can also contribute to this loss in bone density, and in some cases can lead to osteoporosis. Because a greater loss of bone density will often happen within the first few years after your final menstrual period, its a better indication of menopause than a thyroid issue.

What Causes An Overactive Thyroid Gland

Menopause, How to Cope Hot Flashes and Night Sweats?

The thyroid gland is found in the neck. It produces hormones that are released into the bloodstream to control the body’s growth and metabolism. These hormones are called thyroxine and triiodothyronine.

They affect processes such as heart rate and body temperature, and help convert food into energy to keep the body going.

In hyperthyroidism, the thyroid gland produces too much thyroxine or triiodothyronine, which speeds up the body’s metabolism.

There are several possible underlying causes, the most common being Graves’ disease, in which the body’s immune system targets the thyroid gland and causes it to produce too much of the thyroid hormones.

Overactive Vs Underactive Thyroid

The thyroid is a butterfly-shaped glandlocated at the front of your neck. It produces hormones that help regulateyour bodys metabolism and keep your brain, heart, muscles and other organsworking properly. But sometimes it does too much or too little, as seen in:

  • Hyperthyroidism: An overactive thyroid may make you feel nervous, irritable and shaky. You may notice a racing heart, excessive sweating, heat intolerance, frequent bowel movements, thinning hair, weight loss and irregular periods.
  • Hypothyroidism: An underactive thyroid gland may slow down your body functions. What to look for: slower thinking, depression, feeling cold, constipation, muscle weakness, abnormal periods and a slower metabolism leading to moderate weight gain.

Loss of memory, or brain fog, is another, often-overlooked, sign of a thyroid issue, adds Dr. Kellis. Though rare, losing hair around the ends of your eyebrows is another sign.

Determining The Underlying Cause

Hyperthyroidism & Thyroid Storm Signs & Symptoms (& Why They Occur)

If tests confirm an overactive thyroid gland, you may be referred for further tests to determine the underlying cause.

An additional test that may be used is an isotope thyroid scan. This involves swallowing small amounts of a radioactive substance , usually technetium, in capsule or liquid form.

A scan is then used to measure how much of the isotope has been absorbed by your thyroid gland.

If your thyroid gland absorbs a high amount of the isotope, it is likely the underlying cause is either Graves’ disease or thyroid nodules.

If the amount is low, the underlying cause could be due to:

  • swelling of the thyroid gland , often caused by your immune system mistakenly attacking thyroid tissue or, less commonly, by infection
  • having too much iodine in your diet
  • in rare cases, thyroid cancer

Special Considerations For Taking Levothyroxine

Avoid eating within an hour of taking levothyroxine. Schedule your hypothyroidism dietmeals and levothyroxine dosage hours apart. A consistent schedule is easier to keep to. Many people tend to take their medication immediately upon waking for convenience, then eat an hour later.

If you are pregnant, breastfeeding, or plan to become pregnant, talk to your doctor about optimizing your dose of levothyroxine for you and the infant. During pregnancy, many women will benefit from a slight increase in their dose of levothyroxine, and this can usually be reduced postpartum.

If you suffer from any of the following diseases, discuss with your healthcare provider the increased risk of taking levothyroxine:

  • High blood pressure

The less thyroid hormone that your body naturally produces, the higher your prescription drug dosage will likely be. The more body weight you have, the higher your dosage may be.

The more susceptible to levothyroxine side effects, the lower your dosage should be. History of heart disease, diabetes, or seizures would likely necessitate a lower dosage.

Note: Certain medications and multivitamins also reduce the absorption of levothyroxine. Eating food within a few hours of taking levothyroxine may reduce its absorption. Take levothyroxine on an empty stomach.

Your Guide To Thyroid Medication

Optimizing your thyroid levels with thyroid hormone replacement medication is usually the first step in minimizing symptoms.

Stay away from dietary and environmental triggers

Certain foods, smells, and environments can increase your risk of having night sweats.

  • Avoid spicy foods before bedtime
  • Avoid drinking alcohol or caffeine before sleep
  • Avoid smoking or inhaling second-hand smoke
  • Avoid sleeping in a warm room
  • Avoid stress or sleeping in a stressful environmentâ

Prepare your sleep environment

If you repeatedly struggle with night sweats, consider taking some preventative steps to lower your risk of waking up in wet sheets.

  • Turn down the thermostat and turn up the fan.
  • Wear light, loose-fitting pajamas, or skip them altogether. If you find you also struggle with cold intolerance, consider wearing layers to bed that can easily be removed.
  • Use light blankets or sheets.
  • Have a glass of cold water next to the bed.
  • Consider using pillows and mattress pads designed to cool your body as you sleep.

Establish a bedtime routine

Much like a child has a specific bedtime routine to help them wind down for rest, adults also benefit from having a routine. Wind down the same way each day: take a cool shower, shut screens off at least an hour before sleep, avoid late-night snacking, do yoga, massage, or journal. Allowing your body and mind to relax can signal your body that it is time to rest.

Does Hypothyroidism Cause Night Sweats


People who live with hypothyroidism struggle with heat regulation. Cold intolerance is the most common thermal symptom of hypothyroidism. However, some people may also experience night sweats. When the thyroid gland is compromised, and hormone levels are off-balance, you can experience uncomfortable temperature-related symptoms.

When To See A Healthcare Provider

Pin on Health

Contact your healthcare provider if you’re experiencing symptoms of too much levothyroxine. They can do tests to check your thyroid levels and figure out if youre being overmedicated.

If your provider determines that you are taking too much levothyroxine, they will reassess your treatment plan. They might advise you to change your diet if it’s contributing to thyroid overmedication. Your provider might also change your medication or adjust your dose.

Do Certain Meds Or Supplements Cause Hot Flashes

Question posted by Gertrude80 on 24 April 2022

Last updated on 24 April 2022 by adoptmeow

I suffer many times a day from overwhelming heat. Not in circumstances that should cause it. Other people seem comfortable. Had a complete hysterectomy in 2005 and was bothered for a few years with hot flashes, helped by OTC meds. They are not helping now. This is making my life miserable. It does not interrupt my sleep.


Vitamin E deficiency caused me to have hot flashes. I took 800 IU each day and they stopped. Now I stay on 400 IU, which also increases my energy level. Be careful to get the natural Vitamin E with related compounds like tocotrienols , not the synthetic dl-alpha.


“Hot flashes are a side effect of many prescription medications, including:Opioids.Calcium channel blockers Vasodilators Some steroids.”

Stanford Health Care Introduces New Less Invasive Treatment For Benign Thyroid Nodules

A recently approved technique for radio-frequency ablation treats or prevents problems caused by thyroid nodules, providing an alternative to surgical removal of the gland.

Sarah OBrien with her husband and children. OBrien underwent radio-frequency ablation at Stanford Health Care to treat nodules on her thyroid a procedure that obviates the need for surgical removal of the gland.Sarah Laureno

When Sarah OBrien injured her neck in a car accident in 2012, a doctor examining her medical scans happened to notice that she had nodules on her thyroid, a gland located just below the Adams apple on the front of the neck. At the time, she was 24 and had no idea what that even meant.

Over the next eight years, after her neck injury was long forgotten, those nodules grew into a goiter-sized lump that protruded from her neck and caused a range of symptoms, including explosive anger, fatigue, muscle weakness and hot flashes. Medications helped some, but the best available treatment option was the surgical removal of the thyroid, an important gland that secretes hormones controlling the bodys metabolism. She kept putting off the surgery hoping that a better option would emerge. Finally, it did.

Earlier this year, OBrien became the first patient at Stanford Health Care to undergo a nonsurgical treatment, recently approved by the Food & Drug Administration for benign thyroid nodules, called radio-frequency ablation.

Signs Of Overtreatment To Look Out For

Hyperthyroidism vs. Hypothyroid RN LPN NCLEX

Its important to be familiar with the signs of overtreatment for hypothyroidism. Symptoms of mild overtreatment include:

  • Inability to sleep and/or focus.
  • Abnormally increased heart rate, even at rest.

Two groups of people with hypothyroidism are at high risk of complications from overtreatment: those with heart rhythm disturbances and elderly people with weak bones. One study reports that hypothyroidism is more common in older women due to Hashimotos disease.

Whether youre young, old or in between, dont adjust the dose yourself if you think youre being overtreated, says Dr. Skugor. Call your doctor and explain your symptoms. They will check your blood levels of thyroid hormone. The correct dose adjustment will soon have you feeling a whole lot better.

Women Of All Ages Get Hot Flashes

It is estimated that over 75% of perimenopausal women suffer from hot flashes. Although most prominent in women during the menopausal stage of life, any age of women can experience them.

Hot flashes can be described as flushing with a sensation of warmth or heat on the upper body and face. For some women, they may occasionally occur with no real impact on their lives, while other women suffer with intense cyclical occurrences that disrupt their daily lives.

Tsh Tests And Advanced Thyroid Testing

The TSH test is a great blood test that helps figure out if you have an early stage thyroid disorder. It measures the level of thyroid-stimulating hormone in your blood. It may detect hypothyroidism or hyperthyroidism way before the levels of thyroid hormone in the body go out of whack.

A high TSH level means that your thyroid is underactive and you possibly have hypothyroidism. On the other hand, a low TSH level typically indicates an overactive thyroid, and that the gland is producing too much thyroid hormone.

If thereâs an anomaly â for instance, a tumor or inflammation â that is hindering the pituitary gland from stimulating the thyroid gland enough, the test will also return a low TSH result. This is referred to as secondary hypothyroidism.

If your TSH test comes back as abnormal, there are other thyroid tests that your OBGYN, endocrinologist, or physician can order to get to the root issue of your thyroid imbalance including:

The most definitive way to know if youâve got a thyroid problem is through the above-mentioned blood tests.

Are Hot Flashes A Side Effect Of Synthroid

Question posted by lexusgirl23 on 28 July 2012

I am 36 years old and since I started on synthroid I have been having hot flashes. I do not think I am going into menapause as my family members didn’t until they were in their fifties. Could this be a side effect?


Hi there,

I’m on Synthroid and don’t have that problem from that but I heard that having Rai treatment can bring on menopause. I just started hot flashes since then.

Buy yourself a hand held fan for when it happens, that’s what I did. Helps alot!

+0Patiently Waiting

I had “hot flash” type symptoms when my doctor increased my dosage. My previous dose.. I was cold, my hands/feet/ butt were always real cold.. dangerously cold in winter. When I started heating up I didn’t know how to cool down.. I was never hot before. Still having over heating problems in full sun, and learning how to stay hydrated in summer. The hot flashes did ease. It takes your body months to adjust to new meds or increases. If it continues to be a problem after a month or better talk to your doctor about rechecking. It’s better to have your t3/t4 and tsh tested. Hope you get to feeling better.


It can be a side effect, but it can also be an effect of hyperthyroid. When did you have your TSH checked last?
