Health history before treatment
Conditions that rule treatment out
The September 2026 label check rules out tesamorelin for active cancer, pregnancy, or a known allergy to the medicine or its other ingredients.
It also rules treatment out if the pituitary, a gland that makes hormones, cannot work properly.
Tell the doctor about a tumor, surgery, removal of that gland, an injury to your head or radiation treatment involving your head. These can affect the gland or the signals that control it.
The label says people taking it must not breastfeed.
Past cancer is a separate discussion
For a past cancer that was treated and is stable, the label calls for careful weighing of benefit against the chance of its return.
This is a cancer caution, not proof that tesamorelin causes cancer.
The checks listed in the label
The label asks for blood-sugar checks before starting and at intervals during treatment.
It also calls for blood tests of IGF-1, a substance whose level rises when tesamorelin releases more growth hormone.
The label calls for eye checks in people with diabetes, to look for new or worse damage.
The label asks the person prescribing the medicine to review whether to continue if deep belly fat has not fallen.
Bring a list of medicines and ask who orders tests, explains results and handles follow-up.
Keep this in mind
The health-history check and the follow-up plan are part of judging whether treatment fits.
