Hello how may I help you? I need some help opening my prescription bottle. If it is a child proof bottle, try pressing firmly on the cap while twisting. I tried that. There is a tab on the side, that may play a role. Is the tab located near the cap? Yes. Right under. Try holding that down with your thumb while twisting. Okay. It worked. I got the bottle open. How much should I take? Please read the label on the bottle carefully and take only as directed. Okay. Thank you. You're welcome
