ISONIAZID SYRUP 50MG/5ML(SPENAZ
Isoniazid syrup is an anti-tuberculosis medicine used to treat and prevent tuberculosis (TB) when the bacteria are susceptible. For active TB, it is given together with other TB drugs to prevent drug resistance.
What it is
Isoniazid is an anti-tuberculosis medicine. It works by killing the bacteria that cause tuberculosis (TB). It is used both to treat active TB and to prevent TB infection in people who have been exposed.
What it's used for
Isoniazid is used to treat all forms of tuberculosis (TB) in which the bacteria are susceptible. For active TB, it must be taken with other TB medicines to prevent the development of drug resistance. It is also used as preventive therapy for people with a positive skin test who are at high risk, such as those with HIV, close contacts of TB patients, and others as recommended by health authorities.
Common side effects
The most common side effects affect the nervous system and the liver. Peripheral neuropathy (tingling, numbness, or burning in the hands and feet) is the most frequent toxic effect, especially in people who are malnourished, have diabetes, or drink alcohol. Other possible side effects include seizures, vision problems, confusion, and liver injury. Serious skin reactions (rare) such as blistering rashes, fever, and organ inflammation require immediate medical attention.
Important cautions
Do not take isoniazid if you have had a severe allergic reaction to it, including drug-induced hepatitis, previous isoniazid-associated liver injury, or severe adverse reactions like drug fever, chills, or arthritis. It is also contraindicated in acute liver disease of any cause. Watch for signs of liver problems (dark urine, jaundice, fatigue) and skin reactions (rash, blisters). Alcohol increases the risk of liver toxicity. Inform your doctor about all medications you take.
