Hi, Welcome to Healthcaremagic,
Madam, you are taking the drugs which are addictive. Usually during pregnancy
majority of the drugs are avoided. But if it is inevitable like in your case; if you will stop the drug abruptly it may cause withdrawal symptoms
to you; so if you have to take it, after thorough investigations your treating doctor can adjust the minimal doses which can help you and your baby mostly away from the side effects.
I hope you might be satisfied with this answer. Hope for the best.
