What is Isoniazid Syrup Used for?

Isoniazid Syrup (Isoniazid) is a prescription medication used with other antitubercular medications to treat and prevent tuberculosis (TB) in children. Tuberculosis is an infectious respiratory disease that mainly affects the lungs but can also spread to other body parts such as the intestine, kidneys, brain, spine, and bone marrow. The active ingredient in Isoniazid is Isoniazid. Isoniazid belongs to the class of medications called Antitubercular Agents. It inhibits the synthesis of mycolic acids, an essential component of the bacterial cell wall. It works by preventing bacteria from forming the protective cell wall, which consequently causes the death of bacteria that lack a cell wall. It would be best to know that treating tuberculosis with Isoniazid prevents the worsening of tuberculosis or its spread to other parts.

Are there any Precautions and Drug Interactions for Isoniazid Syrup?

Isoniazid syrup should be used as prescribed. It should be taken on an empty stomach, at least an hour before meals, or 2 hours after eating. If your child develops stomach upset after taking Isoniazid syrup, give it with a small glass of water or a snack. Measure the dose with the special spoon that comes with the syrup. Do not use more than the prescribed dose. Taking more medication will not improve your symptoms; rather, they may cause poisoning or serious side effects. Your child may be prescribed a vitamin B6 supplement (pyridoxine) while taking Isoniazid to prevent problems with the nerves (tingling or numbness in fingers or toes) from Isoniazid. You should use this medication for your child as long as your doctor prescribes, even if your child seems better. Talk to a doctor before you stop giving Isoniazid to your child.

You should not take Isoniazid Syrup and inform your doctor about your medical history, especially if you have or have had:
• Diabetes mellitus;
• Hypersensitivity to Isoniazid;
• Kidney disease;
• Nerve problems;
• Severe liver disease

Do not miss your clinic appointment so your doctor can check your child's response to Isoniazid. Your child may need to have regular blood tests done while they are taking Isoniazid. Do not give the syrup to a newborn; otherwise, your doctor directed you to do so.

Tell your doctor about all the medications you use, including prescriptions, over-the-counter medications, herbal products, and vitamin supplements, to prevent drug interactions that might be fatal to your health. This interaction may make your drug less effective, cause adverse effects, or potentiate other drugs' actions. There may be a drug interaction between Isoniazid Syrup and other drugs, such as:
• Cobimetinib;
• Ivabradine;
• Ketoconazole;
• Levoketoconazole;
• Lomitapide;
• Lonafarnib;
• Naloxegol;
• Pacritinib
• Regorafenib;
• Venetoclax;
• Voclosporin
