Taking Akurit-4 for 4 months is safe if your doctor prescribed it for your TB treatment. Sometimes doctors continue it longer to control the infection fully. There is usually no harm when taken under medical supervision, and switching to Akurit-3 is a normal part of treatment.

Low-grade fever can persist for several weeks after starting TB treatment, as the body takes time to respond to the infection. Since your tests are normal and you have been on Akurit-4 for only about 1 month, this may still be part of the recovery phase. Continue your treatment and follow up with your doctor, who may monitor your progress and decide if any further tests are needed.

The best treatment for tuberculosis (TB) depends on various factors, including the type of TB (drug-sensitive or drug-resistant), the patient's overall health, and other medical conditions. Treatment plans may vary from person to person, as there is no single approach suitable for everyone. Typically, a combination of anti-tuberculosis medications is prescribed for 6 to 9 months, but the exact regimen and duration will be tailored to the individual’s needs. It's important to follow the treatment plan provided by a healthcare provider to ensure effectiveness and prevent complications, such as drug resistance. Consulting a TB specialist is recommended for personalised treatment.
