Hi, Both the above drugs are category C drugs in pregnancy, that is they are not to be taken until benefits outweigh risks. We avoid any medication in first trimester as this is when the various organs and organs systems are forming especially between the 5-12 weeks. At 2-3 weeks, if the medicines had to cause harm, a miscarriage would have occurred, what is called the all or none effect. That is if affected the pregnancy would have miscarried by itself, but since it has not, it is most likely that it is unaffected. Regular scan including nuchal scan and anomaly scan will help rule out any defects and reassure you.. I would advise you to continue pregnancy. Hope this helps. Regards.
