Uses: Pyzina 500 MG Tablet is an antitubercular medicine primarily used for the treatment and prevention of tuberculosis (TB), an infectious disease that mainly affects the lungs but can also spread to other parts of the body such as kidneys, brain, spine, and bone marrow.

The dose and duration of treatment are determined by the doctor based on the severity of the disease and the patient's weight. It is crucial to complete the full course of treatment, even if symptoms improve, to prevent the infection from returning or developing drug resistance.

Side Effects:

• Common Side Effects: Muscle/joint pain, nausea, vomiting, and loss of appetite.

Do not stop taking the medicine even if your symptoms improve, as this can lead to drug-resistant TB. Women of childbearing potential should use a reliable contraceptive method as this medicine may affect hormonal contraceptives.

What happens if a dose of PYZINA 500 MG Tablet is missed?

If you miss a dose of PYZINA 500 MG Tablet, take it as soon as you remember.
