Side Effects of Synthroid levothyroxine: Interactions & Warnings

If you never had joint problems prior to taking synthroid, and suddenly noticed muscle weakness, swelling, and pain – there’s a good chance that it’s the medication. This isn’t a commonly discussed side effect, but one that numerous users have reported. If your joint pain continues to worsen, interferes with your ability to exercise and/or well-being – you may need to evaluate other treatment options.

Drug-Laboratory Test Interactions

Since synthroid has a narrow therapeutic index (NTI) for dosing, even slightly too much of the synthetic hormone may provoke a tailspin of unwanted symptoms, most of which resemble hyperthyroidism (or excess thyroid hormone). If you are taking synthroid and suspect that you may have ingested an excessive amount, it is important to beware of severe synthroid side effects and adverse reactions. That said, it is possible that some users may experience anxiety even after the synthroid dosage is calibrated to an optimal level. Users may report physical symptoms of anxiety such as muscle tension, sweating, and increased heart rate – as well as psychological symptoms such as rumination or obsessive thoughts. If you’re experiencing severe anxiety and/or panic attacks from your synthroid, talk to your doctor about a dosage adjustment, alternative intervention, and/or concurrent usage of an anxiolytic. If you’ve been taking synthroid, it is necessary to track whether the therapeutic benefits attained from the medication outweigh side effects and adverse reactions.

Adverse Reactions In Pediatric Patients

In 2014, I suffered a sudden flare-up of my Hashimoto’s after starting to use a new lipstick. A third-party lab test revealed that this particular product had high levels of arsenic, and this matched up with my own toxicity lab results, which showed elevated levels of arsenic. For those of us with Hashimoto’s, this toxin overload can be particularly problematic, as our bodies often struggle to eliminate toxins efficiently. 1 This inability to detox properly can trigger or worsen autoimmune symptoms, as these chemical exposures can trigger immune dysregulation. 2 This is why we need to be especially diligent when it comes to addressing chemical exposure in our day-to-day lives.

If so, advise them to stop biotin supplementation at least 2 days before assessing TSH and/or T4 levels see DOSAGE AND ADMINISTRATION and DRUG INTERACTIONS. Administer SYNTHROID at least 4 hours before or after drugs known to interfere with SYNTHROID absorption see DRUG INTERACTIONS. Our Synthroid Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication. Drug interactions of Synthroid include blood thinners because Synthroid may increase the synthroid corn effect of blood thinners. Larger doses may produce serious or even life-threatening manifestations of toxicity, particularly when given in association with sympathomimetic amines such as those used for their anorectic effects.

Always consult your healthcare provider to ensure the information displayed on this page applies to your personal circumstances. Tell any doctor, dentist, or surgeon who treats you that you are using Synthroid.

• Some users may find that after several months of synthroid treatment, sensitivity to heat decreases and/or normalizes.
• Get medical help right away, if you have any of the symptoms listed above.
• Also consider that if you experience recurrent hot flashes for a span of months after taking synthroid, it could be a sign that your body is unable to tolerate an exogenously-administered, synthetic hormone.
• In its healthy state, the thyroid gland helps regulate many of our bodily functions.
• You are encouraged to report negative side effects of prescription drugs to the FDA.

The signs and symptoms of overdosage are those of hyperthyroidism see WARNINGS AND PRECAUTIONS and Adverse Reactions. Seizures occurred in a 3-yearold child ingesting 3.6 mg of levothyroxine. Symptoms may not necessarily be evident or may not appear until several days after ingestion of levothyroxine sodium.

Drug Summary

Checking 13 to 24 symptoms means moderate toxicity, and more than 25 indicates severe toxicity. However, when the office worker keeps getting more and more paperwork dumped on her desk without replenishing the tools she needs to complete her work, a backlog can occur. We make it easy for you to participate in a clinical trial for Hyperthyroidism, and get access to the latest treatments not yet widely available – and be a part of finding a cure.

Pesticides may also be found in drinking water and depending where you live, may also be in the air. Filtering your air and water is another good way to reduce your exposure – as mentioned, I love AquaTru’s countertop filter and AirDoctor or Jaspr air filters. Even cleaning, laundry, fragrance, and personal care products marketed as “natural” or “green” can still contain chemicals that have been artificially synthesized, and could cause health problems. Opt for fragrance-free products whenever possible, and make swaps for everyday household products. Our detox pathways may become overwhelmed and overburdened, and we end up with a toxic backlog.

Does Hypothyroidism Cause Night Sweats?

Understand that the number and severity of your symptoms will likely be contingent upon how much more synthroid you took than was necessary. When initiating treatment, certain patients may run the risk of taking too much synthroid. In a majority of cases, individuals that take too much synthroid do so unintentionally. It is common for patients to misinterpret dosing instructions given by a medical professional and/or pharmacist and mistakenly ingest larger than instructed doses. These improvements can be life-changing for people, and my clients and readers who follow liver support protocols are always amazed at their results. Angry thoughts that I was holding onto released, my skin looked younger, I had more energy and finished projects that were on the “backburner” for years, and I effortlessly lost around 5 pounds.

Anytime appetite increases/decreases are substantial and/or sustained for a prolonged period – they should be discussed with a medical professional. Some Hashimoto’s patients with a sluggish liver may also notice an extreme sensitivity to foods and drugs. Many of my clients who have reported chemical sensitivities and allergies to different foods and medications, would frequently react to just about any benign and helpful supplement that I would give them. These reactions are often due to the toxic backlog that is present in their body, which can cause them to react to everything in their environment as well. When the thyroid gland is compromised, and hormone levels are off-balance, you can experience uncomfortable temperature-related symptoms. The higher affinity of both TBG and TBPA for T4 partially explains the higher serum levels, slower metabolic clearance, and longer half-life of T4 compared to T3.
