mixing brands of different levothyroxine dosage

[Thyroid2020]

hi there

My Pharmacist has now mixed the brands of my levo. I’m on 150mg for 2 days then day 3 I am on 175mg and that’s how I am taking them.

Recently my 100mg is brand TIVOLI 50mg is TEVA and 25mg is whatever the chemist has in stock sometimes.

The teva makes me feel unwell and exhausted. Pharmacist says these are the brands they can only get but mainly teva.

Any advice as I’ve read that you shouldn’t mix brands. Any thoughts on this

Mixing brands works for some people but for many it does not. However, to get the same brand consistently your GP needs to write the brand on the prescription (in the first line) or you need an accommodating pharmacist who will make a note on your record there. If the brand is written on the prescription (correctly) then the pharmacist can't dispense another brand.

The teva makes me feel unwell and exhausted.

In that case tell your GP and pharmacist and put in a Yellow Card Report.

How to make a Yellow Card Report:

You take 150mcg x 2 and 175mcg on day 3. If you don't deviate from that pattern then you can work out your daily average like this

Over 14 days you take

Day 1 + 2 - 150mcg = 300mcg

Day 3 - 175mcg

Day 4 + 5 - 150mcg = 300mcg

Day 6 - 175mcg

Day 7 + 8 - 150mcg = 300mcg

Day 9 - 175mcg

Day 10 + 11 - 150mcg = 300mcg

Day 12 - 175mcg

Day 13 + 14 - 150mcg = 300mcg

So over the 2 week period you are taking 2,200mcg, so 1,100mcg per week which averages 157mcg daily. You could say rather than have 50mcg Teva then if they can't get another brand of 50mcg then you will cut your 100mcg tablets in half.

I've never heard of Tivoli brand of Levo, are you sure that's correct or maybe it's a new one to the market.

I suspect a typo or an auto-correct issue with the name TIVOLI.

There is no such product in the UK (nor can I find one anywhere else).
