I have hypothyroidism (I was born with 2/3 of a thyroid) and I have the correct dosage. I take it as directed, but now I feel DEPENDENT on it. I'm supposed to take it daily, but I ACCIDENTALLY skipped two days and went absolutely insane in fits and moodiness and got tired. I took it and started crying because I was fighting with my poor 9 year old cousin really bad. (I'm 14). Now after about 18 hours I'm starting to go insane without it. What's up? I used to be fine, it was just a pill I took. Now it's weird because I have fits w/o taking it. Answered by Frederick Pent 4 months ago.

Taking Synthroid is not a drug where you have dependency issues. This is a hormone that you need to take daily in order to replace the amount of hormone you're not getting because of the smaller sized thyroid gland. By not taking it, you eventually go back to being hypothyroid, with all of the problems related to that condition - note, I said eventually. Skipping one or two doses isn't going to make much, if any, difference in how you feel and function. Synthroid has a half-life of about a week - meaning that it takes a week before the Synthroid circulating in your body gets down to about 1/2 of the dose you normally have. I rather doubt that skipping for 18 hours or even a couple of days is going to actually affect you so much that you become moody and tired; it could be that you are thinking that skipping a dose or two is going to cause you to get tired and moody - and by thinking so, your mind turns those thoughts into reality. (yes, this can really happen) It could also be that you're experiencing the normal hormonal and mood fluctuations that most teens experience at one time or another during this phase of life. I suggest that you keep taking your Synthroid on a daily basis, don't double up your dose if you forgot yesterday's dose, and don't worry about it upsetting your life. Answered by Della Blacksher 4 months ago.

It is not an addiction...your thyroid has to be given what it is missing .. w/o treatment w/ meds, you would have these thyroid disease symptoms (yours may have been caught before it ever got that bad @ the beginning). WHY ARE YOU MISSING IT!?! You should always take it as soon as you awaken (I mean like early a.m.), on an empty stomach, then not eat for at least 30 minutes. THIS IS SERIOUS! A 14 yr old is capable of understanding and doing this. I have never missed mine but then I have only been on it three mos (Praise the Lord for it!) but I have friends that can tell a difference if they are later in the day taking theirs. God bless you Answered by Darrell Pugeda 4 months ago.

Yes you are dependant on it, but not because you are addicted - its because your body can't produce enough of the hormone. The mood swings are probably larger now because additional hormones associated with puberty are also affecting your mood. IT might be a good idea to have blood test to look at the thyroid hormone levels along with some of the adrenal hormones. Answered by Jeanette Villalovos 4 months ago.

simply it is hormonal compensatory treatment not a mood stabilizer and simply if i was in your place i would stick to the medicine and what doctors say it has no side effect it is just like when iam hungry i should eat Answered by Neil Marsolek 4 months ago.


I take synthroid AND I consume soy products and walnuts. Now I hear this is not safe. True?
Asked by Adam Semple 4 months ago.

Synthroid is a drug that damages your body because it is a synthetic drug used to replace the thyroid hormones. It causes your thyroid to shut down and then you are dependent upon that drug for rest of your days here on earth. That is "MAKE BELIEVE HEALTH." Doctors use this because they are either lazy and don't want to take the time to determine why your thyroid is not working properly or have no clue what to do and how to find out what is keeping your thyroid from working. Soy that is NOT fermented like the Japanese consume, contains lots of goitrogens that slow your thyroid down and is contraindicated by the drug companies that make Synthroid. Look at the paperwork with the tiny writing you get with your Synthroid and you will see that there is a warning telling you NOT to eat any soy products. The soy industry has been successful in indoctrinating the public into believing it is good for you, when in fact, it is terrible for you for many reasons. Soy reduces the sperm count in males about 50%, removes minerals from the body and in particular, iron (over 50%), and will actually cause men to get "man boobs" and become more feminine due to the high content of phytoestrogens that are NOT the right kind for health. Soy is very high in the heavy metal, Aluminum that causes many problems with the thyroid. Fermented soy is tolerable and has some redeeming characteristics to it that can nourish the body in some ways. Soy sauce, miso, and natto are O.K. to eat. Natto, in fact, has nattokynase that will lower your blood pressure. Things like tofu when originally devised was found to lower the libido and it was used extensively by monks for this feature. It worked then, and it works the same way now. Soy was originally used to put nitrogen back into the soil and it works really well for this, but should NOT be used as food. Here's a good book for you to read, "The Whole Soy Story" by Kaayla Daniels. This is a peer reviewed book and is an excellent source for understanding the "whole story" about soy. Walnuts are no problem. Then you need to find out what is causing that thyroid to not work well and doctors are NOT going to help you do this. Do a simple test on yourself. Go to the store and get some "tincture of iodine" and paint a patch 2" x 3" on your forearm. Do this in the morning and see how many hours it takes for that patch to disappear. It should be visible 24 hours later. If it disappears in a few hours, that may be what is causing your thyroid to not work; a deficiency in iodine. E-mail me and I believe I can help you with this issue. EDIT: Broccoli and Cauliflower also contain goitrogens and if you lightly cook them (steaming is good), this takes that problem away, but don't eat raw Broccoli or Cauliflower. Good luck to you Answered by Manuela Dryman 4 months ago.

Synthroid And Soy Answered by Pia Hilborn 4 months ago.

soy can slow down thyroid function and that's probably what you have heard. It's not going to hurt you to eat the soy, it will just be more difficult to get the proper dosage of Synthroid. Your thyroid probably produces a little of its own hormone. By eating soy, you are slowing down its production. The soy they eat in Japan is not the same as it is here. Here its over processed, making it not as healthy. Walnuts are fine to eat and are very healthy for the heart and lowering cholesterol levels. Answered by Sabina Sakkinen 4 months ago.

True with the soy, I'm not sure about the walnuts. I also know that cabbage is not good with synthroid. Answered by Carmela Konwinski 4 months ago.


When is the best time of day to take Synthroid?
Asked by Marquis Dannatt 4 months ago.

Synthroid is supposed to be taken 1 hour before food or two hours after. Don't take your synthroid with beverages that contain calcium (i.e. milk or oj). Try to take it with a full glass (at least 8 oz.) of water For me it's easier to take it at night before bed because the first thing I do in the morning is to drink a cup of coffee with lots of cream. I seldom eat anything after dinner so that gives me plenty of time to have an empty stomach before I take it. I asked my doctor about if there was any difference between taking it at night or in the morning and she said no, that what counts is that you take it without food and regularly. Also, I don't know if you're male or female but if you take birth control pills or use any kind of estrogen product you are not supposed to take that at the same time you take your synthroid. Answered by Walton Aubin 4 months ago.

If you are taking Synthroid to make up for a lack of natural hormone, it is important to take it regularly at the same time every day. You will probably need to take it for the rest of your life. If possible, take Synthroid as a single dose, preferably on an empty stomach, one-half to one hour before breakfast. The drug is absorbed better on an empty stomach. If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Never take 2 doses at the same time. If you miss 2 or more doses in a row, consult your doctor. Answered by Mica Duignan 4 months ago.

Synthroid is synthetic hormone therapy and is very bad for you. It is the lazy doctor's way of treating a problem by relieving a symptom with drugs. This does not make your thyroid healthy and does not get to the root cause of the problem. It does create a situation where you have to go to the doctor each year and get a blood test to keep the doctor supplied with money and the drug companies supplied with money and the pharmacist supplied with money, leaves you with less money and a body that is deteriorating, but keeping the symptoms relieved. I certainly hope you are NOT taking 150 milligrams of that drug. Most likely you are taking 150 mcg of the drug. To get off the drug, you will need to figure out what is causing the problem with your thyroid. Most doctors are simply NOT trained to do that. The first thing is to determine if you are deficient in iodine. Your thyroid gland only uses about 4% of the iodine you ingest, the rest goes to other organs in the body. If you are deficient, it takes several months of ingesting iodine to get your thyroid put to par so it can make it's own T3 and T4 hormones normally. You cannot just stop taking synthroid suddenly and have to be weaned off it as the thyroid starts getting back its ability to make the hormones. It's a real mess what doctors are doing to people and it takes some work to make this happen as a result of the damage the drug does to you. To test your iodine, you can just get some Tincture of Iodine from the drug store and paint a patch 2" x 3" on your forearm early in the morning. You should be able to see the patch 24 hours later. if it disappears in a few hours, that indicates you are very deficient in iodine and that is most likely the problem. This is the most typical reason for thyroid problems. Once you know this is the problem, you can address it with supplements. I would see a nutritional therapist that can truly help you back to becoming healthy and get off those very stupid drugs. good luck to you Answered by Verla Catrett 4 months ago.

Did anyone experience dizziness after taking Synthroid?
I have been feeling even more tired and more dizzy after taking this medicine. I feel so dizzy and so out of it, I've been on it for about 2 weeks. Is this normal. I want to feel better and energized already. I also feel like pressure headaches. Im just not comfortable. Oh and I have the runs. Asked by Ethyl Ruckdaschel 4 months ago.

I used to take Synthroid but, never had any dizziness. The patient insert lists nervousness but, no dizziness. Call your doctor & let them know about your symptoms. They may need to adjust your dose but, they usually say that it takes about 4-6 weeks for you to really feel the difference. Synthroid has a long list of drugs that can cause interactions. They are: Amiodarone Androgens (male hormones) Antacids and anti-gas medications Antidepressants Blood pressure drugs Blood-thinning drugs such as warfarin and heparin Chloral hydrate (a sedative) Cholesterol-lowering drugs Diabetes drugs, including insulin Digitalis-type drugs such as digoxin Estrogen products and oral contraceptives Furosemide Growth hormones Hormone inhibitors Immune system drugs such as interferon and interleukin Iodide Iron supplements Kayexalate Ketamine Lithium Methadone and heroin Metoclopramide Nonsteroidal anti-inflammatory drugs such as phenylbutazone and aspirin Parkinson's drugs Propylthiouracil (a thyroid inhibitor) Seizure medications Steroids such as dexamethasone and hydrocortisone Stimulants such as epinephrine Sucralfate The cancer drugs 5-fluorouracil, 6-mercaptopurine, mitotane, and tamoxifen The tranquilizers perphenazine and diazepam The tuberculosis drugs aminosalicylate, rifampin, and ethionamide Theophylline A high-fiber diet, soy-containing supplements, and walnuts can also interfere with the effects of levothyroxine. Tell your doctor if you take any of these prescription drugs. *Also, high blood pressure & diabetes are conditions listed that may cause your symptoms to be worse.... these conditions may affect your dosage. The extra fatigue, dizziness, & diarrhea may indicate that you are getting overstimulated. Definitely call your doctor....you may need to have more blood work done to check your current thyroid levels. Good luck! Answered by Rupert Milledge 4 months ago.


Tsh levels WAY high & synthroid help?
If your Tsh is high, your thyroid is usually low. THS is thyroid stimulation hormone. Tsh is produced to try to make your thyroid stimulated to produce more. Thyroid test numbers are confusing as a high tsh means low thyroid for this reason. Asked by Jeremy Thilges 4 months ago.

Been on synthroid for years at 25 MCG, this kept my TSH at about 5-8. 2 years ago my TSH suddendly started going up, med slowly increased. 1 year ago, my TSH was 55.772, T4 6.2, t3uptake 29, Free thyroxine index 7.8 so everything was normal except my TSH, the doctor upped ,my synthroid to 100mcg 1 year ago. Today the TSH is higher again at 73.224, but the T3, t3 uptake & free index are all perfecty normal. He wants to leave my synthroid at 100 mcg again this year since the actual thyroid is normal. I told him I would really like to slowly increase it to 112mcg & then probably 125mcg in 3 months if the TSH was still high. I am lucky sort of as I do have dry skin in cold weather, dry hair, (But normally dry, course & curly all my life). Energy is ok as long as I do get 8 hours sleep, any less sleep & I am a basket case. Stress & being rushed & hurried & I get really anxious & to the point of panic, dizzy etc. Do I need to get a second opinion? Or is my synthroid level ok still? Answered by Hershel Dominquez 4 months ago.

I used to take synthroid and now I'm not taking any at all. It has taken me a lot of time to get to this point. Synthroid is very bad for you and is the doctor's easy way out of a problem they just don't want to spend time figuring out. It leaves you with a thyroid that is being slowly killed by the synthroid, dependent upon it for the rest of your life, and chained to the doctor each year who loves seeing you walk through his door and looking at your blood samples. There are many reasons thyroid glands slow down and you need to go to a real doctor that will take the time to figure it out and not some 15 minute whiz bang guy that just wants your money and does not care about what that drug is doing to you. The TSH test is just not sensitive enough and is only the tip of the ice berg tests that need to be done to figure out what is really going on with you. I found out that I was simply deficient in iodine that was causing my problem and when I fixed that, I fixed my thyroid. But the Synthroid did a lot of damage and it took several months to fix the problem once I figured it out. Additionally, I had a severe head trauma that blocked my 20th meridian that was reflexing to my thyroid, keeping the energy level low. I fixed that by clearing my lymph system with herbs and my 20th meridian cleared with very special clay packs. The reason you are a "basket case" when you don't get sleep is because your body needs to get at least 5 hours of uninterrupted sleep to allow you to go into a REM sleep. Without getting to the REM state, your adrenal glands do not get recharged and your energy level the next day will be greatly affected, and you will feel dizzy if you stand up quickly. I also suggest STRONGLY, that you test yourself for iodine deficiency. Paint a patch of "tincture of iodine" on your chest about the size of a golf ball. If the stain goes away before 24 hours, you are deficient. The thyroid only uses about 3% of the iodine you take in and the rest of your organs use the rest, including your skin. Anything with Fluoride of any kind in it will make you deficient in iodine. ALL soy products that are not fermented will slow your thyroid greatly. Look at your literature in the synthroid packet and you will see they tell you to avoid SOY! I believe you should find a doctor that cares and dump the bozo you are going to. good luck to you.

Synthroid Levels Answered by Jaimie Varona 4 months ago.

You need a different doctor. Once on thyroid treatment, the morning TSH should be below 2.0. Keeping you at a TSH of 5-8 is poor care. The other tests your doctor did don't tell much. What you need is a free t4 and free t3. These tests show the actual amount of these hormones avaiable for use. A TSH over 2.0 could be causing elevated cholesterol levels and heart problemsdone the road. Links below Answered by Tarah Teman 4 months ago.

Definitely get a second opinion. Your TSH is way too high! Once you get your TSH in tact, you will have more energy and feel a LOT better. Find an endocrinologist that has good experience with thyroid issues. Many endocrinologists treat diabetes patients and are just so/so when it comes to thyroid. Also, get a copy of your records and take them with you to your second opinion appointment. Answered by Shondra Gowins 4 months ago.

This makes no sense. If you have a high TSH (thyroid stimulating hormone), then you should have plenty of hormone in your blood. Synthroid is what y ou take to increase the thyroid. If you are allready high in hormone, why would you want to increase it? If you have too much Synthroid in your system you will feel panicy/wired-like too much coffee/very agitated/ unable to sleep or relax. Get to an endocrinologist or at the very least an internalist.

I also take Imitrex and Vicodin when I get severe migraines, Klonopin if I can't sleep, is it okay to take those with Synthroid too?

Synthroid will not interact with any of the other meds. Take Synthroid as directed, usually in the morning 30 minutes before breakfast. Do not take antacids or iron supplements within 8 hours of thyroid medication. Do not change brand names and do not stop taking it without consulting your MD. Do not eat excessive amounts of goitrogenic foods (eg, asparagus, cabbage, peas, turnip greens, broccoli, spinach, brussel sprouts, lettuce, soybeans). However, the other medications DO interact with each other. Ultram and Imitrex shouldn't be taken together. It can be serious if you taken both together often. "Patient Management The concomitant use of agents that enhance serotonin activity should be undertaken with great caution. Patients should be monitored for the development of serotonin syndrome during such therapy. The manufacturers of some agents have contraindicated the use of certain drugs due to this problem." (FYI Serotonin Syndrome is what Anna Nicole's son died of) ---- Ultram, Klonopin, and Vicodin should not be taken together. They all depress the CNS and together can depress it too much and cause problems. This is not too serious of an issue but you definitely shouldn't take them all together on a regular basis. "Patient Management The concomitant use of two or more drugs that have the potential to depress CNS function (either as a therapeutic intention or a side effect) is often clinically appropriate. However, it is important to recognize that the risk of unwanted effects may increase with such use. Monitor for additive CNS-depressant effects if two or more CNS depressants are concomitantly used." ---- Make sure you only go to one doctor and one pharmacy. Most pharmacies probably wouldn't tell you about the 2nd drug interaction, but it can be important, especially if breathing becomes difficult or if you drink at all. Good luck! Answered by Dayle Mervis 4 months ago.

You shouldn't have any problems taking Synthroid and Ultram together, or Synthroid and any of the other medications you listed. As far as when you should take it, the only suggestion I could find is that you should take Synthroid on an empty stomach. Otherwise, you should be fine. Of course, as with all medications, if you have any concerns or problems the best course is to consult your doctor. Answered by Freddy Toole 4 months ago.

Does every one get hair loss from synthroid?
It seems like that is what I read. The symtoms of hypothyroidism include hair loss already so synthroid should improve the imbalace. Asked by Jaqueline Violett 4 months ago.

No. Nobody gets hair loss from synthroid. That's not a side effect of synthroid. Synthroid is a rare drug that doesn't actually have any side effects. Side effects are *unintentional* effects of a drug, unrelated to what the drug is supposed to do. You might read that tachycardia is a side effect if synthroid, but it isn't. The purpose and intention of synthroid is to increase your T4, and hopefully your T3 also. So raising your T4 and T3 are INTENTIONAL effects. Not side effects. But if you take too much synthroid, you will raise your T4 and T3 too much. and your T4 and T3 will be too high. That is called hyperthyroidism and hyperthyroidism causes tachycardia. So taking an overdose of synthroid can cause tachycardia, but it isn't a side effect. Anyway, hair loss is caused by hypothyroidism, not synthroid. Your hair will stop falling out once you are euthyroid. Therefore, synthroid will cause your hair to STOP falling out. It doesn't cause your hair to fall out. Many people believe this fallacy that synthroid causes hair loss though. It is what we call a propter hoc fallacy. You have hypothyroidism. You take synthroid because you have hypothyroidism. You have hair loss. And then people jump to the conclusion that the synthroid use cause the hair loss when it didn't. Synthroid and hair loss are only have a correlation, not a causative relationship. Hypothyroidism causes you to take synthroid. Hypothyroidism causes hair loss. So both synthroid use and hair loss are caused by hypothyroidism. Therefore, since they have a single cause, they are correlated. But that's all the farther that you can go without committing a logical fallacy. Answered by Salena Folts 4 months ago.
