Hi welcome to Health care magic forum. You had hypothyroid condition and started eltroxen tablets, you should continue with the same for life. Regarding yasminelle we cant comment any thing, and if find any difference in health you can consult your doctor and act accordingly.
Whether you get acne
back if you stop the yasmenelle depends upon individual variation. may or may not get it. As you are using it since 4years and you must have crossed the acne getting age you can try stoping it , if you get acne you can start it again.
To support hypothyroid, and acne prevention, you can follow some diet recommendations,as take more of green leafy vegetables, pulses, sprouts, fruits, juices, plenty of water, salads, to have good hemoglobin
levels and resistance of the body.
Don't worry if you want you can continue with both, thanks for calling.
