Almus v activas

Has anyone else noticed any difference?

I had. TT four years ago and have been on 100 thyroxine not ideal but I get along

I usually have Almus brand and have been ok .three times I have been given activas and have noticed after a week I feel awful very tired

and aching all over .

I queried this with the pharmacist he said there was absolutely no difference as they are manufactured by the same company.

Has anyone else has same problem

There have been posts before about problems with Actavis. Have a look through the posts that come up via the search box healthunlocked.com/search/p...


Actavis is their brand name used by Boots for Almus Levothyroxine.

When I last looked, the patient information leaflet in Actavis boxes was branded Almus.


If I am reading you right - it is the exact reverse. :-)

Some Actavis levothyroxine is packaged up for Boots under the name Almus. (Almus is a brand name owned by Boots under which a number of products from various manufacturers are packaged.)

The Patient Information Leaflet inside will have the number of a product licence - like PL 9999/999. Check the number on both the Actavis and the Almus products. I think that both will be the same at the same dosage.

The PILs for Actavis can be found on these links:




You are correct.

I was relying on my memory, as I was not at home to check.

Just to confuse me, the most recent 50mcg Levothyroxine that I received from Boots was branded Actavis.
