Tuberculosis (TB) is a communicable disease and one of the leading causes of death worldwide, caused by Mycobacterium tuberculosis .1, 2 Despite the availability of effective treatment, TB continues to be a major public health concern. Isoniazid is one of the most commonly used first-line antitubercular drugs due to its high efficacy and cost-effectiveness .7 However, its use is associated with various adverse drug reactions (ADRs), which may affect patient compliance and treatment outcomes .26The present review aims to evaluate the pattern, incidence, and types of adverse drug reactions associated with isoniazid therapy in tuberculosis patients. A comprehensive review of literature was carried out using previously published studies from different settings and populations. The findings suggest that a significant number of patients experience at least one ADR during the course of treatment.The most commonly reported adverse drug reactions include gastrointestinal disturbances, nausea, vomiting, hepatotoxicity, skin reactions, peripheral neuropathy, and fatigue. In some cases, severe adverse effects such as hepatitis and neurological complications have also been reported. It was observed that the majority of ADRs occur during the initial phase of treatment. 25, 26In conclusion, although isoniazid remains a cornerstone drug in tuberculosis management, careful monitoring of patients is essential for early detection and management of ADRs. Proper patient counseling and regular follow-up can improve treatment adherence and reduce the risk of complications, thereby enhancing the success of tuberculosis control programs
Tuberculosis (TB) is a communicable disease that is a major cause of ill health and one of the leading causes of death worldwide. Until the coronavirus pandemic, TB was the leading cause of death from a single infectious agent, ranking above HIV/AIDS. Tuberculosis is caused by a bacterium known as Mycobacterium tuberculosis. It spreads from person to person through the air when an infected individual coughs, sneezes, or sings, releasing tiny droplets containing the bacteria. These droplets can be inhaled by others, allowing the infection to enter the lungs. People living or working in crowded conditions are at higher risk of transmission.1, 2The total number of people who develop TB each year shows that approximately 90% are adults, with a higher prevalence among men than women. The disease most commonly affects the lungs (pulmonary TB) but can also involve other parts of the body. If left untreated, the death rate of TB is high (about 50%); however, with currently recommended treatment, about 85% of patients can be cured. Treatment regimens ranging from 1 to 6 months are available for TB infection .1Healthcare workers are at increased risk of Mycobacterium tuberculosis infection due to frequent exposure to patients with active pulmonary TB. Latent tuberculosis infection (LTBI) among healthcare workers has been reported to be as high as 64% worldwide. Approximately one-third of healthcare workers have been diagnosed with latent TB infection using interferon-gamma release assays, which is higher compared to other populations. Managing and treating LTBI in healthcare workers is important, as those who develop active TB can easily transmit the infection to patients. Additionally, individuals living with HIV have a significantly higher risk—about thirty times greater—of developing active TB compared to non-infected individuals .3, 4
HISTORY OF TUBERCULOSIS
Tuberculosis (TB) has been present in humans for thousands of years. The earliest evidence of TB was traced back to approximately 9,000 years ago in Atlit Yam, a submerged city off the coast of Israel. Historical records suggest that TB reached India around 3,300 years ago and China about 2,300 years ago. Mycobacterium bovis (bovine TB) is still found in many animals, including cattle and deer. Approximately 1 million cattle are tested annually for TB, and animals that come into contact with infected wildlife are at higher risk. In some cases, transmission of TB from animals to humans is also possible .5In the 1800s, physicians advised patients suffering from tuberculosis—then commonly known as “consumption”—to rest and consume nutritious food. It is an airborne disease that primarily affects the lungs, leading to symptoms such as persistent cough, fever, and chest pain .6In 2012, the Government of India declared TB a notifiable disease, similar to HIV, dengue, hepatitis B, malaria, polio, and chickenpox. This means that all diagnosed TB cases must be reported to government authorities. The Government also provides free treatment under a national program. The Revised National Tuberculosis Control Programme (RNTCP) was launched in 1997, and its treatment guidelines were later revised in 2010 .7
SYMPTOMS OF TUBERCULOSIS
Tuberculosis progresses through three stages: primary TB infection, latent TB infection, and active TB infection, with symptoms varying at each stage.Primary TB Infection:- This is the initial stage of infection. In most individuals, the immune system destroys the bacteria; however, some bacteria may survive and remain in the lungs. Many people do not show symptoms at this stage, while some may experience:
Latent TB Infection: - In this stage, the immune system forms a protective barrier around the infected tissue in the lungs. The bacteria remain inactive and do not cause symptoms. However, they can become active later if immunity decreases.Active TB Infection: - This occurs when the immune system is unable to control the infection. Active TB may develop soon after primary infection or after a long period of latency. Common symptoms include:
Extrapulmonary TB: - TB infection can also spread to other parts of the body. Symptoms depend on the affected site but commonly include:
RISK FACTORS OF TB INFECTION
Several factors increase the risk of developing tuberculosis infection:
A weakened immune system significantly increases the risk of TB infection progressing to active disease. Conditions and factors that weaken the immune system include:
There are two main types of tests used for the detection of tuberculosis infection: the skin test and the blood test. Both tests help to determine whether a person has been infected with Mycobacterium tuberculosis, but they cannot differentiate between latent and active TB infection.
Skin Test: - The tuberculin skin test (Mantoux test) is the most commonly used test, especially in children under 5 years of age. It measures the immune response to a purified protein derivative (PPD) injected under the skin. PPD is a protein derived from Mycobacterium tuberculosis and does not contain live bacteria. If a person is infected, a firm red swelling appears at the injection site within 48–72 hours.
Blood Test: -The interferon-gamma release assay (IGRA) is a blood test used particularly for healthcare workers and immunocompromised individuals. In this test, a blood sample is taken and analyzed for the release of interferon-gamma in response to TB antigens.10
CHEST RADIOGRAPHY
Chest radiography is recommended for all individuals being evaluated for latent or active TB. Pulmonary TB typically presents with infiltrates in the upper lobes of the lungs, especially in the apical and posterior segments.11
SMEAR MICROSCOPY
Smear microscopy for the detection of acid-fast bacilli (AFB) is one of the most rapid and cost-effective methods for diagnosing tuberculosis .11
DIAGNOSIS OF TUBERCULOSIS
A complete evaluation for tuberculosis includes the following components:
THE EFFECT OF TB STIGMA ON TB DIAGNOSIS OR TREATMENT
Tuberculosis (TB)-related stigma is widely considered to be a significant factor contributing to delays in diagnosis and negatively affecting treatment adherence. Several qualitative studies have reported that community members, TB patients, and healthcare providers perceive stigma as a major barrier to timely diagnosis and effective management of the disease.Individuals experiencing symptoms suggestive of TB may initially seek care from private healthcare providers in order to avoid social stigma. However, private healthcare facilities often have longer waiting times and higher costs, which may lead to delays in diagnosis and increased financial burden on patients.
Attempts to quantify the impact of TB stigma on diagnostic delay and treatment adherence have produced mixed results. Some studies have shown that stigma is not a significant predictor of delay in seeking healthcare. For example, studies conducted in Uganda, Zambia, and Syria found that factors such as daily alcohol use and socioeconomic conditions were more strongly associated with delays than perceived stigma. Nevertheless, stigma remains an important social factor that can influence health-seeking behavior and treatment outcomes in TB patients.12–21

ISONIAZID
Isoniazid is an antibacterial drug available in 100 mg and 300 mg tablets for oral administration. Each tablet contains inactive ingredients such as colloidal silicon dioxide, lactose monohydrate, pregelatinized starch, povidone, and stearic acid.The chemical name of isoniazid is isonicotinyl hydrazine or isonicotinic acid hydrazide. Its molecular formula is C?H?N?O, and its molecular weight is 137.4.Isoniazid is an odorless, colorless, or white crystalline powder. It is freely soluble in water, sparingly soluble in alcohol, and slightly soluble in chloroform and ether. It is slowly affected by exposure to air and light .23
MECHANISM OF ACTION OF ISONIAZID
Isoniazid is bactericidal against actively growing bacteria and bacteriostatic against resting bacteria. It acts as a prodrug and becomes active after entering the body.

ADVERSE EFFECTS OF ISONIAZID22
Adverse drug reactions (ADRs) associated with isoniazid may vary among individuals. Commonly reported ADRs include:
Although most patients tolerate the drug well, any occurrence of ADRs should be reported to a healthcare provider. The incidence of major adverse effects per month of treatment has been estimated to be 0.49% for isoniazid, 0.43% for rifampin, 1.48% for pyrazinamide, and 0.07% for ethambutol. However, cumulative toxicity may become significant, and ADRs can lead to discontinuation of treatment in approximately 11% of patients. Second-line antitubercular drugs are associated with a higher incidence of adverse effects.26

CONCLUSION
In this review, the incidence of adverse drug reactions (ADRs) was found to be at least one in the majority of patients. The maximum number of patients included in the reviewed articles was 424,203, while the minimum number was 1. After analyzing these studies, the most commonly reported ADRs were:
The majority of adverse drug reactions occurred during the initial phase of treatment. Therefore, conducting regular and thorough follow-up of patients during this phase can help in early recognition and appropriate management of ADRs. This will improve patient compliance and confidence in the Revised National Tuberculosis Control Programme (RNTCP), ultimately contributing to its success.With the increasing prevalence of drug-resistant tuberculosis, it is essential to create awareness among DOT providers, healthcare workers, patients, and family members regarding the importance of early detection of ADRs. Strict monitoring of therapy should be ensured to prevent treatment noncompliance and negligence. Efforts should also be made to develop new anti-tubercular drugs and strengthen pharmacovigilance systems to reduce treatment duration and improve safety.It was also observed that a lack of awareness about national tuberculosis programs and public health facilities may lead to negative perceptions of public healthcare services. This can make it difficult for economically weaker patients to access proper treatment. Additionally, some TB patients prefer private healthcare services due to concerns regarding the quality of care and medications available in public health facilities.
