Based on my references, there is no interaction between synthroid and phentermine. I have no data on Hoodia. Caution should always be used when mixing medications and in general should be avoided when possible.
Have you had follow up tests to ensure that your
hypothyroidism is now under control? Weight gain is a symptom of
hypothyroidism. If you are still low on thyroid hormone your metabolism slows down making it a) easier to gain weight and b) harder to loose weight already gained.
Hope this helps.
