Common side effects of rifampicin include orange discoloration of the urine saliva sputum, flu like symptoms, and liver dysfunction. Common side effects of isoniazid include peripheral neuritis, hemolysis, and liver dysfunction. You should take vitamin-B6 containing supplements to prevent isoniazid associated peripheral neuritis. Yes, you can conceive while taking these medications as they do not cause any harmful effects on your unborn child. Hope I have answered your question. Let me know if I can assist you further.
