Meds you can take after thyroid problems

With the pollen and allergy season arriving, I'm just curious about the sinus/allergy medications you can take. I was told not to take anything that says in the very fine print not to take if you have have thyroid problems, so I was wondering how these meds affected the majority with thyroid issues and what to take.

you should be able to take everything you could before

if you are going on LID you have to watch the ingrediants though

also make sure you dont take anything around the time you take your thyroid meds

no food 3 hours before thyroid meds or 1 hour after

calcium and Iron as well as some others i cant remember right now for 2 hours after.

ok serching and doing my cut and paste again

Many drugs affect thyroid hormone pharmacokinetics and metabolism (e.g., absorption, synthesis, secretion, catabolism, protein binding, and target tissue response) and may alter the therapeutic response to SYNTHROID. In addition, thyroid hormones and thyroid status have varied effects on the pharmacokinetics and actions of other drugs. A listing of drug-thyroidal axis interactions is contained in Table 2.

The list of drug-thyroidal axis interactions in Table 2 may not be comprehensive due to the introduction of new drugs that interact with the thyroidal axis or the discovery of previously unknown interactions. The prescriber should be aware of this fact and should consult appropriate reference sources (e.g., package inserts of newly approved drugs, medical literature) for additional information if a drug-drug interaction with levothyroxine is suspected.
Drugs that may decrease T4 absorption, which may result in hypothyroidism

- Aluminum & Magnesium
- Simethicone
Bile Acid Sequestrants
- Cholestyramine
- Colestipol
Calcium Carbonate
Cation Exchange Resins
- Kayexalate
Ferrous Sulfate
Concurrent use may reduce the efficacy of levothyroxine by binding and delaying or preventing absorption, potentially resulting in hypothyroidism. Calcium carbonate may form an insoluble chelate with levothyroxine, and ferrous sulfate likely forms a ferric-thyroxine complex. Administer levothyroxine at least 4 hours apart from these agents. Patients treated concomitantly with orlistat and levothyroxine should be monitored for changes in thyroid function.

also talk to your pharmicist about things they actualy are good with drug interactions.

You are like an encyclopedia full of knowledge. I have noticed that before they removed my thyroid Benedryl use to knock me out. I could take Tylenol allergy & sinus (daytime) and be fine. After my thyroid, benendryl no longer makes me sleepy and I was working at the DMV and took Tylenol allergy and sinus and fell asleep for 30 minutes on a break. The pharmacist said Claritin and Mucinex D (not the other Mucinexes) was all I could really take.

I am just good on webserches

I have most the sites that i have reserched and have good info bookmarked.

Pharmacists normaly have a good idea about medical interactions and i have a few of them that are my friend so i chat with them alot.

again the reason i am so "good" at reserching is i decided to ask any and every question and I also check every side effect from every medicine and that i do a job that I end up with spair time now and then to do reserch while I wait for people to need me to supervise a section of QA work.

Thanks Nasher,

I wish I knew about this before my surgery.

After my total thyroidectomy, my calcium levels were a little low. This, or so I was told, is not unusual following a TT. The parathyroids, which control calcium absorption, are adjacent to the thyroid and can have their function temporarily impaired by the surgery.

Now here is the amazing part. The solution was to have me taking four Tums a day. The active engredient in Tums? Calcium carbonate. I was taking two with breakfast, or only one hour after the levothyroxin and two with dinner. If I had taken the Tums only with dinner I would have been all right. Yet neither the attending physician at the hospital who wrote the prescription, nor the head and neck surgeon who was very concerned with the parathyroid issues, said anything about this.

I have no idea if my levothyroxine intake was affected by this, but looking back I was having some hypo symptoms that have decreased {or at least noticably changed} since I went off the Tums. The problem is, my symptoms, constipation and minor cramping, could have been due to the Tums itself, the levothyroxine itself or the combination of both. Who knows?
