### input:
my husband was diagnosed of PTB thru cultured sputum (possitive) then the doctor requested him to repeat his sputum test for 3 consecutive and 1 skin test, all are negative. But the still required him to take rifamficin 600mg Pyrodoxine 50 mg Pyrazinamide 1500mg Isoniazid 300mg and ethambutol 1200mg that was from UAE doctor, but since here in the Philippines we dont have single pack of medicine can he take the Quad tab consist of Pyrazinamide 400mg, Enthambutol HCI 275mg, Rifamficin 150mg, and Isoniazid 75mg? the questions are: is he really need to take medicines and if yes can he just take the quad tab instead but what dossage he need 4 time a dya to meet the prescribed medication of UAE doctor or he can just take quad tab 3 times a day and when is the best time to take it before of after meal?

### output:

Thanks for your question on Chat Doctor. If sputum culture for AFB is positiver than he should take anti TB treatment for at least 6 months. And ideal daily dose for 1. Rifampicin is 450 mg2. Isoniazid is 3003. Pyrazinamide is 15004. Etambutol is 1200So you need to take 4 quad tablets to meet the standard dose of anti TB Chat Doctor. And best is to take on empty stomach.  But if he feels heaviness in stomach or gastritis or nausea than can take after light meal.
