Welcome to ChatDoctorI appreciate your concern for your husband. Glad to know that the first phase the intensive phase of Anti TB treatment is over. The problems your husband having are due to the side effects of Chat Doctor.  Nothing to worry about them, These problems are self limiting. If vomiting becomes severe, you may give him Omeprazole once daily this will prevent nauseating sensation as well. For constipation, he may take some laxative like Bisacodyl or lactulose at bedtime or give him fresh fruits or leafy vegetables. Ask him to
