Levothyroxine shelf life

Common Questions and Answers about Levothyroxine shelf life

synthroid

Brand name drugs are held to a stricter requirement for the amount of active ingredient in each pill, and the <span style = 'background-color: #dae8f4'>shelf</span> <span style = 'background-color: #dae8f4'>life</span> of the active drug. Brand name drugs are allowed 5-10% +/- variation from what the label says to what the drug measures fresh and at end of shelf life. Generics are allowed a variation of 25%, plus or minus, and there is no guarantee that the pharmacy will stock the same generic from month to month.
I cant tell you what the <span style = 'background-color: #dae8f4'>shelf</span> <span style = 'background-color: #dae8f4'>life</span> is of synthetic thyroxin when not refridgerated. Maybe it just night be worth seeing if you need an increase?
I'm wondering if I could get to advice as to how much Naturthroid to start verses my <span style = 'background-color: #dae8f4'>levothyroxine</span>. I have looked up the conversion from Naturthroid's website, but everyone says to go slow. I just had blood work done last Thursday (2-28-13). I haven't gotten the lab report yet, but hoping I will from my doctor's office today. I know I'm probably asking to soon before you have my new labs, but I am wanting to get some good advice .
Akrimax Pharmaceuticals.....FDA approved in 2006. <span style = 'background-color: #dae8f4'>shelf</span> <span style = 'background-color: #dae8f4'>life</span> of 18 mos. (Longer and more stable than the pills) Tirosint is a gelcap. Potentcy isn't affected like the other T4 meds that have to be heated etc. Comes in 25, 50, 75, 100, 125, 150 (13mcg dosage on way) Dosages are all color coded. Comes in blister packs also with days of week on it I believe. :) Inacive ingredients: gelatin, glycerine, water That's it folks!! FREE of: dyes, gluten, alcohol, lactose, sugar!!!!
This change is being made to help ensure that <span style = 'background-color: #dae8f4'>levothyroxine</span> retains its potency over its <span style = 'background-color: #dae8f4'>shelf</span> <span style = 'background-color: #dae8f4'>life</span> -- a problem that levothyroxine has had in the past, and continues to have. The current requirement is that each pill must contain "not less than 90.0% and not more than 110.0% of the labeled amount of levothyroxine sodium." The change is mandating that each pill will need to contain "not less than 95.0% and not more than 105.
I am not sure what will happen but I think since it has a <span style = 'background-color: #dae8f4'>shelf</span> <span style = 'background-color: #dae8f4'>life</span>, I would call my doctor and ask his advice. If I might make a suggestion, try keeping a notebook and writing down the time and day that you take your meds. Keep it with your medication and you will have a record of when you take it. If you don't think you took it then you probably didn't and you will be ok. You also could call ask a nurse or poisen control, they may be able to help or your pharmacist.
8 weeks sounds more feasible. armour has a shorter <span style = 'background-color: #dae8f4'>shelf</span> <span style = 'background-color: #dae8f4'>life</span>, so will have a shorter time lasting in the system. wait the the other 2 weeks to make it a total of 8. better to be safe.
feel like I have done the biggest mistake of my <span style = 'background-color: #dae8f4'>life</span>. My thyroid problem was diagnosed in 2010 and I didn't take it seriously till Jan 2012, at which time my TSH was whopping 30, fT3 and fT4 at 5 and 12 respectively .. after which I was on regular meds and met a great endo and finally after regular follow ups my levels were Tsh = 0.1, T3 = 4.1 and T4 = 14 in Oct 2012...
The explanation I got was this is because the Thyroxin is NOT a generic brand and doesnt hold a good <span style = 'background-color: #dae8f4'>shelf</span> <span style = 'background-color: #dae8f4'>life</span> either. These were prescribed to me as I am having RAI next week for Hyperthyroidism and Graves. So yes you are correct but I would get a letter from your Doctor stating they must be refridgerated or they may make you keep them in your overnight bag on the plane. Also with the way airlines are now (especially Qantas) about medications this is the way to go.
Everything ok they said, But still i trimble, tried, and big knot on left side neck. I did talk Dr. out 30 <span style = 'background-color: #dae8f4'>levothyroxine</span> 50 mg.. Knot gone but I am still in bad shape.The knots comes and goes...
Eutroxsig Brands are the only two available) it is recommended that we keep thyroxine refridgerated because of issues about the potency, stability and bioavailability (tablets can be left unrefrigerated for one month without affecting <span style = 'background-color: #dae8f4'>shelf</span> <span style = 'background-color: #dae8f4'>life</span>). You don't have to refridgerate Synthroid and other brands do you?
sleepy, constipation, dry skin, hair falling out. The medicine helped. About two years later she insisted with a bit of a fight with doctor to let her try Armour. All of her symtoms have disappeared. For HER Armour is better. levothyroxine supplies T4 and your body must be able to convert it to T3. Armour has both. Go to the Armour web site. They have good info under facts etc. There is an awesome article at http://www.thyroid-info.com/articles/mercola.
Also has anyone tried prozac which is supposed to have a very short <span style = 'background-color: #dae8f4'>shelf</span> <span style = 'background-color: #dae8f4'>life</span> and have less icky side effects.?? I am getting new labs (B12, D3, ferritin, iron,reverse T3 along w/frees) Right now I eat gluten free, treadmill 3xwkly, walk 6blocks uphill to school, and take melatonin at night to curb insomnia and take my meds faithfully w/out food and my daily handfull of supplements after lunch. So I'm not giving up. THANK YOU ALL SO MUCH!!!!!!
As a preservative it keeps old food preserved longer and that has to do more with <span style = 'background-color: #dae8f4'>shelf</span> <span style = 'background-color: #dae8f4'>life</span> and not your dog’s health. BHA is more for the manufacturers to sell it to grocery stores so it can sit on the shelf longer than other foods. What does Ethoxyquin do for your dog? Well it can kill it. People who work in the rubber business and were exposed to Ethoxyquin contracted skin cancer, blindness, leukemia, diarrhea and liver damage.
T4 is the storage hormone and it takes up to 6 weeks to stabilize. It is very long <span style = 'background-color: #dae8f4'>shelf</span> <span style = 'background-color: #dae8f4'>life</span>. Part of this is because the body ONLY uses the FT3 hormone. And T4 must be converted to T3 and that takes time. The bottom line is for something that takes weeks to level off, whether you take it once during the day or twice doesn't matter. Using a straight T3 or even Natural Dissected Thyroid which has a T3 component in it however is different.
It doesn't last forever either. Meaning its <span style = 'background-color: #dae8f4'>shelf</span> <span style = 'background-color: #dae8f4'>life</span> isn't that long. That's why I can only get a couple of months worth at a time. And lastly, its important that I take it 1 hour before or 2 hours after eating(so on an empty stomach), and at the same time every morning. Otherwise I may not absorb it all into my system. Hope this helps.
So if you miss a day, the system has reserves from the past 6 days of taken medication to fall back on. This is called <span style = 'background-color: #dae8f4'>shelf</span> <span style = 'background-color: #dae8f4'>life</span>. Some people claim there are med. sensitive (shake head) so I guess anything is possible.
I've been on 25mcg of <span style = 'background-color: #dae8f4'>levothyroxine</span> for 6 weeks now. I only had a few good days during my second week, but now Im back to feeling the way I was before. I was only told a TSH number over the phone, but when I called back to schedule my 6 week blood test, I asked about FT3 and FT4 and the nurse told me what all was included in the thyroid panel, by sending me here: https://www.labcorp.com/wps/portal/!
that can ever ever replace real people and there real <span style = 'background-color: #dae8f4'>life</span> stories and experiences. By the way the amount of ALA given at Dr. Berkson is carefully measured on case by case basis and he was FDA authorized as the first physician ever to do ALA IVs in the 70s. Yes that long !
I would recommend in-patient detox to anyone who wants to get off of this stuff ... it is poison, it will destroy your <span style = 'background-color: #dae8f4'>life</span> and eventually kill you. It gives you a false sense of happiness, you feel like you can do anything, but in reality you are so dependent on it that you actually can't do ANYTHING. Quitting isn't easy, but it was the best decision I had made in a LONG time.
I do have to be honest and say that, having been an airline crew member for almost all of my working <span style = 'background-color: #dae8f4'>life</span>, the amounts of alcohol we, as a group, consumed when we were away would probably have horrified most medics. Nevertheless, these symptoms have only really manifested themselves since I retired last year .. and I would say that my alcohol consumption since that time has dropped by around 80% - although I also have to concede to having at least a single drink on most days ...
Let me tell you that cream was a <span style = 'background-color: #dae8f4'>life</span> saver . I had tried everything, Differant MD's telling me this and giving me that. That biopsy made life a whole lot better. Now I control it. But, I still have itching till this day. I have learned to live with it. I was told by a MD once "IT is a old lady disease". I really had trouble when I was younger thinking I had to live with this the rest of my life. I have to take that med with me evrytime I go overnight anywhere.
I've suffered from a severe case of IBS (Irritable Bowel) for most of my <span style = 'background-color: #dae8f4'>life</span>, and have had cases such as this happen to me often. It may or may not be related to some form of allergy. You should contact a specialist (gastro-intestinal), and please be sure to drink water, for the diarrhea and sweating can dangerously dehydrate you. It may also be the case of why you get so dizzy.
I have experienced this off and on my entire <span style = 'background-color: #dae8f4'>life</span> (I'm 34). I notice that it is worse after going out in public. When I was a teenager, I always associated this lasting cigarette smell in my nose with a trip to the mall. I am looking this up right now because I just spent 4 days at a convention held in 3 hotels. Both of those places are very likely to use the kinds of cleaning products you're talking about. I've read all the theories on brain tumors, colds, and sinus infections.
I have had this problem all my <span style = 'background-color: #dae8f4'>life</span>, but not all the time....sometimes I don't notice them too much because the pain goes away within hours. Recently though, I had one break in my palm under the thumb joint and it turned to a bruise. I work in a nursing home and most of the nurses there have never heard of it. I don't take any meds and have low blood pressure. I do crochet though....???? I always thought it happened to everyone.
I've gotten pregnant before through IVF but none ended in a healthy birth. We're praying for otherwise, this time. A few days after the IVF, I would have bet my <span style = 'background-color: #dae8f4'>life</span> that again this was a success due to similar symptons as with my previous pregnancies... (I get a bloody nose, pain in my lower abdomen, and breast pain). But a few days later, none of the above symptoms exist, so now we're again waiting to see what the outcome of my blood test will be on Monday.
This is a serious toxic situation and one that is not understood by the medical community. I am waiting to find out how much of my <span style = 'background-color: #dae8f4'>life</span> I will get back. I am rebuilding my stamina & neuropathways with an optimistic outlook. And getting the word out. MD's don't know about vitamins. Work with nutritionists.
I am looking at colleges to apply to. I have been smiling all day and can't believe I have a second chance at <span style = 'background-color: #dae8f4'>life</span>. But I'm sorry I let you down.
