<s>[INST] Hello! First of all, I am 15 weeks pregnant! I also have ADD and have been taking Adderall 30mg daily for almost a year and a half - up until I found out I was expecting, my family physician said not to take Adderall at all during my pregnancy - but my OBGYN said it was ok. She had told me Adderall was a medication C and that it will be safe to take during the second trimester. I am still unsure of how to handle this situation though because I cannot focus what so ever without the Adderall, but I also do not want to harm my unborn child. Thank you very much for your time. [/INST] Hello, and I hope I can help you today. All prescription medications in the US are given a "pregnancy category" which reflects the level of research and effects of a given Chat Doctor.  Class A medications have been tested to be completely safe in human pregnancy. Class B medications have been tested as safe in pregnant animals and have had no detrimental effects in pregnant humans. Class C medications have been shown to be safe in pregnant animals, but there are no studies done on pregnant humans. So what that means is that Adderall has been shown to be safe from animal studies and there is no evidence it is harmful in humans. Most obstetricians will be willing to prescribe Class C medications if the benefit of the medication is worth any potential effects on the pregnancy. This is why your OB told you it is okay to take your Adderall, and I am in agreement with her, especially if it is so hard for you to function without it. I hope I was able to answer your question today and that my advice was helpful. Best wishes for the rest of the pregnancy, </s>
