Isoniazid, Isonicotinic Acid Hydrazide (INH): uses and side effects

Isoniazid and Isonicotinic Acid Hydrazide (INH) are drugs used to treat tuberculosis. They are usually given orally in combination with other antibiotics, such as streptomycin, to prevent TB bacteria from developing drug resistance.

Isoniazid and INH are first-line drugs for the treatment of tuberculosis and are widely used throughout the world. They act by inhibiting the growth and reproduction of bacteria that cause tuberculosis. However, like any medicine, they have side effects.

Side effects of isoniazid and INH are rare, but may include digestive problems and dry mouth. In some cases, patients may also experience nausea, vomiting, headache, drowsiness and other unpleasant sensations.

In addition, more serious side effects such as nerve inflammation may occur when isoniazid is taken in large doses or for too long. To prevent this, pyridoxine (vitamin B6) is prescribed along with isoniazid and INH.

For most patients, isoniazid and INH are safe and effective drugs for treating tuberculosis. However, as with any drug, it is important to monitor for possible side effects and discuss them with your doctor if they occur.



Isoniazid, also known as isonicotinic acid hydrazide (INH), is one of the most effective drugs for treating tuberculosis. It was developed in the 1950s and has since become one of the main drugs used to combat the disease.

Isoniazid comes in tablet or capsule form and is usually given orally. It acts on tuberculosis bacteria that are found in the lungs and other organs. As a result of taking it, tuberculosis bacilli die and the disease goes away.

However, like any other drug, isoniazid has its side effects. The most common is digestive disturbances, which can manifest as nausea, vomiting and diarrhea. Dry mouth and headaches may also occur.

To prevent nerve inflammation caused by taking high doses of isoniazid, patients are also advised to take vitamin B6 (pyridoxine).

Overall, isoniazid is an effective drug that helps fight tuberculosis. However, like any other medicine, it has its side effects, so you must follow your doctor's recommendations and not exceed the dosage.



Isoniazid is one of the most common anti-tuberculosis drugs. It is used in the treatment of patients with pulmonary tuberculosis. Isoniazid is the name given to aminobenzene, which is formed by combining glucose and isonicotinamide. Medicine knows that this medicine is an important means of preventing and combating such a terrible disease as tuberculosis. But to use it correctly, you need to understand the basics of pharmacology. So, let's begin…

1. What is isoniazid? In medicine, this name has a very common substance called benzoylhydroxymethyl nicotinate. It was also previously named inochosindinihydrate and inothiazidinehydrin. However, this substance was synthesized back in the 30s, which means it already has a number of advantages over previously used drugs, for example, isonicotine carbolic acid hydrazide (the former pharmacological name of hydrazine). As Professor V.I. noted in his lecture. Piguzov from the National Medical Research Center of Phthisiopulmonology, drugs of this group are used in comparison with the number of patients
