T3 Is Still Available

I was recently told by my pharmacist that Liothyonine was out of production at the moment and they couldn't get it. Another chemist had some but I sent an email to Mercury and have had this reply so we can all breathe again. Why it is Concordia I don't know. Have they been taken over yet again?

Thank you for contacting Concordia International Medical Information regarding the availability of Liothyronine 20mcg tablets.

I can confirm that Liothyronine 20mcg tablets are available.

In case your Pharmacy is finding difficulty in procuring these tablets, please inform them to contact our Customer Care Team on 02085889441 who will assist them in ordering this product.

I hope you find this information helpful.

Concordia own AmCo who manufacture Mercury Pharma Liothyronine.

It's infuriating when pharmacists claim a drug is no longer manufactured when they have difficulty in sourcing it. Thank you for posting the correction.

Strange they still put Mercury Pharma on the packets. I hope they continue to make it to the same formula.
