Hello AKT4 ( rifampicin+isoniazide+pyrazinamide+ethambutol) is a standard anti tubercular drug and this is a WHO approved treatment for tuberculosis . As you are dentist and belong to medical field , so I want to tell you that take a full course as advised by your treating physician and in any condition don t stop the treatment before stipulated time. Tuberculosis ( pulmonary ) is contagious ( infectious ) disease but only air droplet infection causes infection to other persons , that s why PTB patient advised to cover their mouth with cloth . Usually these all drugs are safe and a patient can use even for 2 1/2 years without any major side effects . Only nausea , vomiting and dizziness are mild side effects . I advise my patient to take pantaprazole 40 mg twice in day on empty stomach for nausea etc. Yes you can conceive after completion of ATT. Good luck.
