Do thyroid pills make you tired after taking?

I've noticed over the years that after I wake up and take thyroid (Levo and now Armour) I get sleepy 20 minutes after. I often fall back to sleep. I stop eating about 6-7:00 pm so basically fasting for 11-12 hours.  I wait 1 hour before eating breakfast or coffee, coffee is only 1-2 maybe 3 oz. After I take thyroid med. I'm hypo by the way.

i do have severe reactive hypoglycemia... Could these pills have something causing me low blood sugar reactions???

anyone experience this?

    I don't know about low blood sugar but I had that "sleepy after 20 minutes" effect when I was on Levo. I would take it at 7:00am and fall asleep about 7:30am - very annoying since I like to be up and about by 8:00am. The "sleepy" thing would keep me asleep until 9:00am if I didn't force myself to get up.

    I think there are many phenomena linked to thyroid medication that have not yet been researched, hypoglycemia may be one of them. Raising of blood pressure is another one, that happened to me and I cannot find too much written about it. It certainly lowers your metabolic rate (evidenced by one's basal temperature, mine is 97.2!).

    Problem is that they have not yet sorted out the major symptoms so "sleepy after 20 mins" is not likely to be studied, probably, in our lifetime.

      I just found a guy on line who says yes thyroid and hypoglycemia and even hyperglycemia can be related. I was tested for Hashimoto's and thought my ENT doctor said yes I have it, but he left our town. I didn't get my records...I know...stupid on my part.  Took me a while to find another doctor, but they don't have records.  I'm going to go to affiliate hospital tomorrow and see if I can find out. 

      I've struggled with hypoglycemia most of my life and it is awful. Doctors don't care.  But as I meantioned, before I even eat now I feel so tired and can't think easily. Ugh. 

      Im also slowly reducing Prednisone corticoid steroid and it affect cortisol, so maybe that's messed up right now too. 

      Thanks for sharing.

      Thanks.

      i read hypoglycemia and hyperglycemia might be connected to thyroid issues.  Hope I can find more info on it. 

      Just trying to figure out the symptom difference now.

    Have you considered taking it at night? Seemed to help a lot of people according to this thread: https://patient.info/forums/discuss/taking-levothyroxine-at-night-improved-my-life--226315

      Wow! Though without reading all 100+ replies... What constitutes an empty stomach?  If take at night, how many hours after eating I wonder. Do you know? 

      I did see the calcium thing recently so I just stopped that !  Seems doctors should tell us about that.

      thanks for link!!!

      Regarding calcium: I like to make sure I get calcium in my diet so I eat a yoghurt every day or drink some Keifer or drinkable yoghurt. But eat/drink it way away from your maximum thyroid meds intake. 

      I do not want to take calcium supplements in pill form because the excess over and above what your body needs can precipitate out in your  kidneys and cause kidney stones.

      Stick with yoghurt or milk.

      Just an added little note. One of the reasons Endos medicate to TSH is because if your TSH is very low (supressed) then they think that will cause osteoporosis. I "ran hot" (i.e. very low TSH - almost imperceptible) for 8 years and because I eat yoghurt my bone density increased! Now, there is another reason: they think it can "harm" your heart. I have no experience with heart problems (after 8 years of TSH < 0.1mlU/L) but if I do I will post my experience here.

      Wow! Your TSH is low! So are you hyper?

      i have Polymylagia so I must take 1200 calcium. Rheumy stopped me on dairy, flour, grains, starches, bad fats, legumes.  Ugh. 

      My primary doctor only test TSH and refused Armour, but my Rheumy said she only does Armour and tests T3 and T4.  I'm new to Armour, maybe two months. 

      I do fear the supplements, I've never believed in them before.  

      Problem is Prednisone (only thing for PMR) increases chance for osteoporosis, and two weeks ago my Dexa said I have osteoporosis. Damn. I'm only 54. Was a triathlete and marathon runner 7 years ago.

      Thyroid meds need to be taken on an empty stomach as food affects the absorption. So either take in morning an hour before breakfast or at night at least 4 hours after food.

      No not hyper, I am hypo at cell level if I don't get external T3 from Armour.The measureing of TSH only tells you what is going on in the blood serum or the efficiency of your pituatory gland, that is the crux of all of the problems.

      Please give your Rheumy a big hug from me for being one of the rare sensible doctors who understands this problem - her efforts are appreciated all the way from California.

      Afraid I don't know sorry! Best I can offer is my magnesium says to take it on an empty stomach two hours after eating and wait an hour before eating again... So that might be a good starting point?

      My TSH was also low (aka 'suppressed') - for 15ish years. I've taken dolomite (calcium and magnesium) for 20+ years and have never had kidney stones and my bone density is 10% better than average for my age. So am I an exception or is it not that simple that calcium causes kidney stones? I have recently had an ECG to check my heart and that came back normal. I still had underactive thyroid symptoms when my TSH was suppressed. My T4 readings had to be just over the top of the range for my T3 to be mid-range and for me to not feel like a zombie. I've recently had an endo tell me I've never had a problem with T3 because it was always in range. What he was failing to look at was the relative position of each within its range when compared to the other i.e. if T4 is top of its range, T3 should also be top of its range.
