What Are The Symptoms Of Too Much Thyroid Medicine

Symptoms Of Too Little Thyroid Medication

Warning-Symptoms of Thyroid OVERmedication

The thyroid gland is a small, butterfly-shaped gland located at the base of your neck. Your thyroid makes hormones that control how your body uses and stores energy. When your thyroid does not produce enough thyroid hormones , it affects virtually all systems in your body. Hypothyroidism can negatively impact your energy, your heart, digestion, and fertility if left untreated.

Some people with too little thyroid hormone may be symptom-free. However, many people with hypothyroidism experience symptoms that feel as if the body is slowing down.

Common signs and symptoms of hypothyroidism include:

  • Muscle aches, tenderness, and stiffness
  • Pain, stiffness, or swelling in your joints
  • Heavy or irregular menstrual periods

Hypothyroidism is diagnosed with a simple thyroid blood test and treated with thyroid hormone replacement medication.

Treatments For Eye Problems

If you have thyroid eye disease but your symptoms arenât severe, you can usually manage them by avoiding bright lights and wind, raising the head of your bed, and using eye drops. Your doctor may suggest a selenium supplement. In some cases, your doctor might prescribe a medication called teprotumumab-trbw . Itâs FDA-approved to treat the symptoms of thyroid eye disease. They might also suggest steroids or other medications to help control the swelling behind your eyes.

For some people, especially those with severe thyroid eye disease, surgery is the best option. There are two kinds that can help severe symptoms:

  • Orbital decompression surgery involves removing the bone between your sinuses and eye socket. It can make more room for your eyes so that they go back to their normal position. It can help improve your vision. There are risks to the surgery, including double vision.
  • Eye muscle surgery is sometimes used to correct double vision. It works by cutting muscles in your eyeball that are covered in scar tissue. Thyroid eye disease can cause this. The cut muscles are then reattached in a different position, which can put your eyes back in proper alignment. You may need this surgery more than once to get the right results.

What Is Postpartum Thyroiditis

Postpartum thyroiditis, or inflammation of the thyroid after giving birth, affects 10% of women.3 It often goes undiagnosed because symptoms are much like the “baby blues” that may follow delivery. Women with postpartum thyroiditis may feel very tired and moody.

Postpartum thyroiditis typically happens in two phases, though not everyone with the condition goes through both phases:4

  • The first phase starts 1 to 4 months after giving birth and typically last 1 to 2 months. In this phase, you may have signs and symptoms of hyperthyroidism because the damaged thyroid leaks thyroid hormones out into the bloodstream.
  • The second phase starts about 4 to 8 months after delivery and lasts 6 to 12 months. In this phase, you may have signs and symptoms of hypothyroidism because the thyroid has lost most of its hormones or because the immune attack is over and the thyroid may recover later.

Side Effects Of Thyroid Blood Tests And Care

Can Too Much Thyroid Medication Cause Anxiety

Thyroid blood tests are performed using a routine blood draw. That’s when blood is drawn from you with a syringe and sent to a lab. This is a safe procedure with few potential side effects.

It’s rare, but some people get nauseous or feel faint when they have blood drawn. Let the medical personnel know immediately if you experience these side effects.

Later, you may notice a small bruise or have some tenderness at the needle insertion site. An over-the-counter pain reliever or an ice pack can help with this.

You should get medical attention if the insertion site is:

These are signs of an infection, which needs to be treated with antibiotics.

Haircoat And Skin Abnormalities

The condition of your cats skin and coat are good indicators of her health status. The VCA Animal Hospital states that a cats coat should be smooth and shiny as opposed to coarse or brittle. Healthy skin should be supple and clear, not bumpy, flaky, or greasy.

If youve noticed changes in your cats hair coat while grooming her, you might want to visit your veterinarian at the earliest possible date. Apart from being a symptom of methimazole overdose, it could also indicate an underlying health issue thats unrelated to hypothyroidism.

Common haircoat and skin abnormalities include:

  • Excessive hair loss and dander
  • Uncontrollable tangles
  • Flaky and/or dry skin

When To See A Healthcare Provider

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.

How Is Hyperthyroidism Treated

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

Your doctor’s choice of treatment will depend on your symptoms and the cause of your hyperthyroidism. Treatments include:

  • Antithyroid medicines block your thyroid from making new thyroid hormone. These drugs do not cause lasting damage to the thyroid.
  • Beta-blockers block the effects of thyroid hormone on your body. These medicines can be helpful in slowing your heart rate and treating other symptoms until one of the other forms of treatment can take effect. Beta-blockers do not reduce the amount of thyroid hormones that are made.
  • Radioiodine. This treatment kills the thyroid cells that make thyroid hormones. Often, this causes permanent hypothyroidism.
  • Surgery. Thyroid surgery removes most or all of the thyroid. This may cause permanent hypothyroidism.

    What Are The Different Thyroid Hormone Medications

    Thyroid hormone replacement is not a one-size-fits-all process. Your thyroid test results, age, other health conditions, and symptoms will determine the type and dose of medication your thyroid doctor prescribes for you. Sometimes, your dose will need to be adjusted to reach a therapeutic level.

    Ahead, some of the different kinds of thyroid medication.

    T4-only thyroid medications

    Levothyroxine is the first line of treatment for hypothyroidism. This medication is a synthetic or human-made form of thyroxine , one of the thyroid’s primary hormones. People taking levothyroxine may take a generic form or a name brand like Synthroid, Unithroid, or Tirosint.

    T3-only thyroid medications

    Triiodothyronine is the other hormone made by the thyroid. For the few patients for whom T4 alone is insufficient, the addition of T3 may be of benefit. Sometimes, a thyroid doctor may prescribe T3 replacement medication if a patient has a hard time converting T4 to T3 or if they take an interfering medication. T3 may be prescribed when a person’s TSH levels or symptoms do not improve despite an increase in T4 levels.

    T4/T3 combination therapies

    Natural desiccated thyroid is a medication derived from the dried thyroid glands of pigs and provides both T3 and T4. Name brands of NDT include Armour, Nature-Throid, and NP Thyroid.

    What Happens If You Are Taking Too Much Thyroid Medication

    In hypothyroidism, taking too much thyroid medication can lead to health concerns and symptoms such as nervousness, anxiety, weight loss, diarrhea, and mood changes. Thyroid hormone requirements may fluctuate with time. Therefore, it is important that only trained professionals administer thyroid medications. Fluctuations in dosage or quality of medication may affect how your body uses it, causing you to become either over-or undermedicated.

    If you are taking too much thyroid medication, talk to your doctor about reducing your dose or switching to a different type of thyroid pill. You might also want to consider other factors that could be affecting your need for thyroid hormones. For example, if you are not eating enough food, then you would expect your body to make more thyroid hormone to try and fix this issue. If you are being treated for hyperthyroidism, then you should not take any additional thyroid pills without first talking to your doctor.

    Because of these possible risks, Synthroid should only be taken as prescribed by your doctor.

    What Foods Should Be Avoided With Hyperthyroidism

    Eating too many iodine-rich or iodine-fortified foods in your diet may cause hyperthyroidism or make it worse in some cases.

    If you have hyperthyroidism, your healthcare provider may recommend certain changes to your diet. Always consult your provider or a registered dietician before making drastic changes to your diet. If you take medication for your hyperthyroidism, always take the amount prescribed by your provider.

    What Are The Signs And Symptoms Of Thyrotoxicosis

    Symptoms of thyrotoxicosis are generally the same in mild and moderate cases, but they’re usually more intense the more severe the thyrotoxicosis is.

    Signs and symptoms of mild and moderate thyrotoxicosis include:

    • Experiencing unexplained weight loss.
    • Feeling nervous, anxious and/or irritable.
    • Experiencing increased sensitivity to heat.
    • Experiencing changes in your menstruation .

    A severe case of thyrotoxicosis is called thyroid storm, or thyroid crisis. This condition is rare and requires immediate medical attention, as it can be life-threatening.

    Symptoms of thyroid storm include:

    • Having a very rapid heartbeat.
    • Having a high fever.
    • Feeling very agitated and confused.
    • Having diarrhea and feeling sick.
    • Experiencing a loss of consciousness.

    What Are The Long

    Thyroid storm – causes, symptoms, diagnosis, treatment, pathology

    Some people prefer a slight overdose when it comes to their thyroid medication.


    Because your thyroid helps to regulate your metabolism by turning on cellular function.

    The more thyroid hormone you have the higher your metabolism will be, the more fat you will burn at rest, and the more energy you will have.

    While this does sound appealing, it doesnt come without a cost.

    As you rev up the cellular machinery in your body you rev up more than just your fat-burning potential.

    Increasing your thyroid dose also puts excess strain both on your bone density and on your heart tissue.

    The absolute risk is not well defined and there are some studies that show that suppressing the TSH does NOT cause these conditions , but they are still important to consider for each person.

    Even if your risk is increased for developing these conditions, though, doesnt mean that you will ALWAYS experience them.

    It may be that taking a higher dose of Synthroid increases your risk of both osteoporosis and atrial fibrillation, but the risk may only increase from say 1% up to 3-4% per person per year.

    These numbers are made up , but these are plausible values based on my own experience and looking at the data.

    How It Works For Tsh Suppression

    Synthroid is used to suppress 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.

    Normally, when your thyroid hormone levels are low, your body makes TSH. This signals your thyroid to make more thyroid hormones. However, if youre taking Synthroid, your thyroid hormone levels wont be low. So your body wont need to make TSH, and your TSH level will be lower than usual.

    How To Take Levothyroxine

    Use Levothyroxine exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.

    Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

    Levothyroxine is taken by mouth. Levothyroxine 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. oralinjection

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

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

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

    What Are The Signs And Symptoms Of Thyroid Nodules

    Most thyroid nodules do not cause symptoms and are not cancerous.8 Some thyroid nodules make too much thyroid hormone, causing hyperthyroidism. Sometimes, nodules grow so big that they cause problems with swallowing or breathing. About one-third of nodules are found by the patient, another third by the doctor, and the other third through an imaging test of the neck.

    You can sometimes see or feel a thyroid nodule yourself. Stand in front of a mirror and raise your chin slightly. Look for a bump on either side of your windpipe below your Adam’s apple. If the bump moves up and down when you swallow, it may be a thyroid nodule. Ask your doctor to look at it.

    Reasons Patients May Take Too Much Synthroid

    Thyroid Levothyroxine Side Effects

    There are several hypothetical reasons as why a patient may end up taking too much synthroid. While taking too much is certainly not the norm, it could be a result of: misinterpreted dosing instructions, improper dosage , or intentionally taking more than usual . Most individuals that take too much synthroid do so unintentionally and/or unknowingly.

  • Misinterpretation of dosing instructions: Some synthroid users may misinterpret dosing instructions as given by their doctor. While dosing instructions are generally confirmed with a pharmacist prior to administration of synthroid, some individuals are more absent-minded than others. It is possible to consider that a simple slip-up on the end of the patient may lead to ingestion of a dose that is larger than necessary.
  • Improperly calibrated dose: Although most doctors attempt to prescribe patients with a minimal effective dose of synthroid, not all patients respond to low doses when beginning treatment. For this reason, a doctor may slightly overshoot the necessary dosing needs for a particular patient. Regular administration of an improperly calibrated dose can provoke symptoms of too much synthroid.
