With all due respect to McA's point of view, I have to say I have always taken my Armour in one dose in the morning before breakfast, and I've been getting along just fine. The prescribing instructions don't say to split the dose - although, granted, it can be helpful for some people to do - but I don't like having to:
A) work it in around eating times and all the calcium pills I take each day;
B) remember to take that second dose in the first place. Memory can be a challenging thing sometimes.
It simply isn't mandatory to split the dose in every single instance. If you have the same concerns I do, don't feel you must do it just because other people do.
Hair loss is listed as a side effect for any thyroid drug. It isn't so much the drug itself that causes that. At the start of treatment, hormones go through a major flux, which causes hair loss in and of itself. Once you find an optimal dose and have stabilized on it, your hair loss should reverse. It may even reverse sooner than that. In either event, try not to worry too much about it. It'll get better.
I just found a substantiated report yesterday that Forest Pharm. (Armour's maker) is being investigated by the FDA for covering up evidence that their antidepressants create a major suicide risk for teens. I suspect ongoing legal trouble is one reason they haven't been paying much attention to their Armour production most recently.
I had a hard time finding Nature-throid, too. Three pharmacies I went to had never heard of it, either. Walgreen's distributor used to carry it but has now stopped, and their pharmacist was unwilling to help me get it. Two different grocery chain's pharmacies use the same distributor who had never heard of it, and they couldn't help. One gave me the name of a different distributor who he knows carries it, and he helpfully suggested I call them to find the names of retailers they service. The distributor wouldn't give me any retail names, so that was a dead end.
Finally, with phone book in hand, I just started calling all the independent pharmacies in the area. When I reached an independent compounding pharmacist, he said, "Oh sure. We have plenty of stock of all the different dosages!" Voilá! Trouble is, I'm on Day 4 of taking that and I feel worse than ever.
I'm not very hopeful about Nature-throid anymore... But at least I can get it. Guess that's sumthin'.
