Weight Loss Clinic Recommended Medication. Could They Be Harmful For My Health?

I am a healthy person but I wanted to know if this is safe to use or should I stop,I wanna lose 20 pounds I have been using them for 10 day and i've lost 4 pounds. I do not want to take them all the time but if I stop drinking them would I gain weight again? my concern is if they could cause me a paralisis or any other bad health problem or death or gain weight again when leaving them. spironolactone 25mg 1 daily phendimetrazine er 105 mg 1 daily thyroid 2gr 1 daily metformin er 500mg 2 daily
