Pandoras Box replied: "I'm hypothyroid, have been for about 55 years. I've taken Synthroid, the generic is called Levothyroxine (currently I'm on Nature-throid). If taken when you don't need it, Synthroid can cause hyperthyroidism which I've had due to over medication. It is extremely unpleasant to say the least. You become hyperactive, you can't sit still, you feel like you've had 100 pots of coffee. You can't sleep. You sweat like crazy even when just sitting still. You get exhausted just walking across the room & you can't do any physical activity at all or you over tax your body. Your heart pounds wildly like it's going to pound right out of your chest. You can have a heart attack or stroke if you take too much Synthroid or if you take it when you don't need it. It can kill you. If you have any of the symptoms I just described, go to the emergency room ASAP! If you have low thyroid, slow thyroid, no thyroid (it was removed or killed off) then you need to take a thyroid medication such as Synthroid, Armour Thyroid, Nature-throid or West-throid to replace the natural accruing hormones your thyroid would normally produce. Your body needs these thyroid hormones for just about every cell in your body. If you don't get enough thyroid hormones, you become sick & can have serious medical problems & even die. Your thyroid affects everything...your heart, your lungs, your brain, your kidneys, everything. Synthroid will not "mess up" your thyroid if you do need it. However, Synthroid is a synthetic thyroid hormone, that is, it is not natural. It only contains the thyroid hormone T4. Your thyroid naturally produces T1, T2, T3, T4, T5. The theory in the medical community is that your body can convert T4 to T3. T3 is the active thyroid hormone that your body uses the most. However, many peoples' bodies cannot convert T4 to T3 so taking a synthetic like Synthroid although helps their hypothyroidism, it often doesn't completely eliminate symptoms of hypothyroidism like a medication that has both T4 & T3 in it. Natural thyroid medications like Nature-Throid, West-Throid & Armour Thyroid have T3 in them as well as all the thyroid hormones your body natural needs...T1, T2, T3, T4, T5. If you take Synthroid when you don't need it, it can start to make you feel horrible within hours. If you take too much Synthroid like I did, it can make you feel horrible in a few hours. Now, if you are taking Synthroid at a correct dosage that your doctor has prescribed & you are just starting to take it for the first time, it can take a while for your body to start to feel better. Usually it takes 6 weeks after you start your first dose of thyroid medication for your hypothyroid symptoms to go away. Your doctor will start you on a low dose & slowly work you up to higher doses to find the right dose for you. Everyone's body is different so not everyone needs the same amount of thyroid medication. It could take up to a year to find the right dosage for you. And throughout your life you will need to get tested to see if you need more or less medication because many things in life will change the way your body needs medication (for instance pregnancy). I have never done well on Synthroid. My doctor switched me to Armour Thyroid & I did very well, but right now there is a nationwide shortage of Armour Thyroid so my doctor switched me to Nature-throid. I am doing very well on Nature-throid & I highly recommend it over Synthroid."

2. If you have hypothyroidism and take Synthroid, it helps regulate the hormone that your thyroid naturally should create. Some people, such as myself, who don't have thyroids take it because our bodies cannot create that hormone on it's own any longer. We need it to stay healthy and alive.
3. According to my endocrinologist, it can take a few weeks to a month for the effects of Synthroid to kick in.
I took Synthroid for awhile but was switched to Levothyroxine. I can't say how I feel about either because my specialists are still working to get my levels right.
(DON'T take this medicine if you don't need it)"
what happens to the BODY and HAIR when the medication Synthroid is stopped for six weeks without the thyroid? i was diagnosed with thyroid cancer and had a full thyroidectomy 2 years ago.
april replied: "Since the thyroid controls hormones, you could be in big trouble heathwise. Why would you be off it for 6 week? You can get it for $4 at walmart.
I did some searching and found this site for you. You need to gradually reduce your meds not stop all at once. Here ya go!"
tharnpfeffa replied: "Before I was diagnosed with Hypo I lost hair all over. My head recovered but I don't have to shave my legs anymore.
Get back on your meds. If you don't have insurance your County Health Dept. should have low cost clinics."
Taking the BC pill while on Synthroid thyroid medication? Will taking one affect the other's effectiveness?
sparkles84 replied: "im not sure. ask you doctor. also read the little thing that comes with your pills it might say."
Chocolate Chip Meringue replied: "The real issue is whether Synthroid is a good thyroid treatment, BC pill or not. And it's not.
Synthroid, Levoxyl, Levothyroxine, et all are T4-only meds. T4 is a storage hormone. They've been prescribed by physicians for nearly 50 years. And...they have never worked. Sure, some may feel better. But nearly everyone on these lousy medications has lingering symptoms of hypothyroidism. And raising it does no good.
Here is a page about T4 meds:
Here is a list of symptoms that linger while on these meds:
What will be a better treatment is desiccated thyroid, aka Armour, Naturethroid, etc. It contains exactly what your own thyroid would be giving you: T4, T3, T2, T1 and calcitonin. As a result, it removes all symptoms.
And here's a summary of everything:
And you'll possibly have to work to find a doctor who is wise enough to understand all this, or one who is at least open-minded about it:
The above pages are from a patient-to-patient website compiled by thyroid patient activist Janie Bowthorpe. She also had a book by the same name, Stop the Thyroid Madness, and I highly recommended it. It's easier to refer to and even has more detail."
