Tuberculous pleurisy usually takes at least six months of medication, but some patients may have drug resistance, resulting in poor treatment results and a longer medication period. Tuberculous pleurisy is caused by Mycobacterium tuberculosis infection of the pleura, can develop at any age, especially in young adults more common, tuberculous pleurisy treatment is the main means of drug anti-tuberculosis treatment, usually need at least six months. Some patients with recurrence of the disease are resistant to conventional anti-tuberculosis drugs, so the treatment program needs to consider a multiple regimen, which requires a longer course of treatment. Tuberculous pleurisy treatment course is longer, too early to stop the drug is very likely to lead to re-emergence, and thus can not achieve the therapeutic effect, so not only is the drug-resistant patients need a longer period of time for treatment, but also some patients with relatively serious conditions, usually the recovery of the therapeutic effect is also poor, and also need a longer period of time for treatment. In the case of relapsed tuberculous pleurisy, treatment may need to be further extended, e.g. the intensive phase usually takes at least two months, and the consolidation phase may take six to ten months, with the overall treatment course reaching more than one year.
