In fact, the product would significantly increase thyroid hormones so yes, people who suffer from hyperthyroidism would have adverse effects by worsening their condition, but in your case hypothyroidism could be treated with too high doses of synthroid so this could also be harmful.
As for insomnia and anxiety, there is very little conclusive data on this natural product. It might help with libido, but only small studies have been done
Stress and anxiety can certainly create libido problems
I suggest you first look at applications such as small bamboo that can give a hand to improve stress and sleep without medication. (meditation, relaxation)
Here are some other tips that can help you
- eat healthy
- sleeping well
- regular physical activity
- avoid alcohol and caffeine
As for sleep, here are a few things to check before turning to medication
- have a routine (get up and go to bed at the same time)
- cut out blue light and liquids after dinner
- go to bed only when you feel sleepy
- avoid naps
- use the bedroom only for sleeping and sexual activities
- consult a psychotherapist
- sleep in a cool, dark environment
- do not have a visible clock
- get up and read when you can't sleep and only go back when you feel tired.
In short, I would turn to these methods first since natural products to treat anxiety, sleep and libido have been very poorly studied with keppra so I would be concerned about the risk of recurrence of seizures not knowing what reaction you might have
Finally, there is a natural gel (zestra) that you can find in pharmacies that could help with libido and that would not cause problems with your medication. You are also young, it would be worthwhile to discuss it with your doctor to see if there is a physical condition that could explain your problem.
I look forward to hearing from you,
