Abuse Of Levothyroxine To Lose Weight Or Enhance Performance
Abusing levothyroxine to lose weight or increase physical energy is not a common practice, but it does occur, especially among athletes. This group is more likely to abuse drugs like this to fool drug tests while getting benefits similar to those of stimulants. A DailyMail report from 2015 highlighted the story of a bronze medal-winning runner who had been pressured by her trainer to take levothyroxine to lose weight in order to compete again.
Although levothyroxine may be misused or abused by some athletes to lose weight for competitions, the World Anti-Doping Agency has not yet listed this medication on their list of forbidden substances. Despite its dangers, athletes are currently free to take this drug even if they have normal thyroid function.
Athletes may abuse levothyroxine as a performance-enhancer, but sometimes, others abuse it to lose weight. Stimulants like Adderall and cocaine have been abused for this reason, and they are more commonly found as drugs of abuse among people who have eating disorders. However, levothyroxine has sometimes been found as a drug of abuse in these cases.

How Long Can You Go Without Thyroid Medication Before Symptoms
A person can go for many years without thyroid hormones. Indeed, people often go undiagnosed for decades despite suffering from hypothyroid symptoms. However, without thyroid replacement medication, a person with overt hypothyroidism cannot function optimally and will suffer from the physical and mental symptoms of hypothyroidism.
The half-life of levothyroxine is 6-7 days, which means it takes about 4-5 weeks for your body to rid itself of levothyroxine. Nonetheless, as synthetic T4 levels start to wane, you can begin to experience symptoms within the first week of not taking your medication.
It is essential to stay current with your thyroid blood tests, thyroid doctorâs visits, and maintain your prescription to prevent a recurrence of hypothyroid symptoms. Keep in mind that it takes between 4-6 weeks before thyroid replacement medication reaches its peak therapeutic effect. Therefore, if you have a lapse in taking your medicine, such as forgetting to pack it on a trip or refill your prescription, it will take time for your symptoms to stabilize.
Thyroid Hormone Replacement Drugs
Levothyroxine is a type of thyroid hormone replacement drug that is often used to treat hypothyroidism. Brand names for levothyroxine include Synthroid, Levoxyl, and Tirosint.
Natural dessicated thyroid is also used to treat hypothyroidism. For some people, NDTs work better than levothyroxine, and many people prefer them because they are more natural. Brand name NDTs include Armour and Nature-Throid.
Usually, people begin thyroid hormone therapy with a low dose that is gradually increased. In part, this is because hypothyroidism progresses over time. But starting therapy with a low dose is also helpful for reducing the risk of overmedication.

If My Tsh Level Is High Should My Synthroid Dose Be Increased Or Decreased
Usually, if your TSH level is high, your Synthroid dose needs to be increased. TSH, which stands for thyroid stimulating hormone, is made when your body needs more thyroid hormones.
When you have an elevated TSH level, your dose of Synthroid may need to be increased. On the other hand, if your TSH level is low, your dose of Synthroid may need to be decreased.
During Synthroid treatment, your doctor will order blood tests to check your TSH level. And for some people, their doctor will also check the levels of their thyroid hormones, T3 and T4. Based on the results of your blood tests, your doctor will adjust your dosage of Synthroid if needed.
If you have questions about whether your dosage needs adjusted, talk with your doctor.
What To Expect If You Stop Taking Your Medication
What should you expect if you stop taking your thyroid medication?
The first thing you should realize is that you are most likely going to feel worse for a short period of time even if your body doesn’t need thyroid medication.
The reason for this is simple:
Once you start taking thyroid medication it causes a negative feedback loop in your brain which REDUCES the amount of thyroid hormone that your thyroid gland produces naturally.
This is a natural and healthy mechanism which is put in place by your body to prevent too much thyroid hormone from being produced.
But the problem is your body doesn’t necessarily know the difference between thyroid medication that you take by mouth or thyroid hormone that your thyroid gland produces naturally.
So once it sees any thyroid hormone it alters the signals that it sends to your thyroid gland by lowering the TSH.
The more thyroid medication you take by mouth the lower your TSH will get.
So, as you stop taking your thyroid medication, it’s only natural that this TSH will start to increase.
But you have to be aware of one major important point.
Once your TSH has been artificially lowered with thyroid medications, it takes time for your brain and pituitary system to get back to full strength.
In fact, it can take several weeks to months for it to get back to the normal state you were in prior to taking thyroid medication.
This by itself isn’t a reason to think that you HAVE to be on thyroid medication, however.
