Isoniazid — All Brands in Nigeria

We list 12 Isoniazid products from the NAFDAC Greenbook — Nigeria's official register of approved products — of which 8 have a currently active registration, including 6 combination products that pair Isoniazid with other ingredients. They are produced by manufacturers including Healthline, Interpharma Industries, Onifam Laboratories, Dony-Triumph and Company Nigeria, Kleef & Helixor Pharm, among others. Combination products, and registrations the Greenbook currently lists as inactive, are clearly marked — Greenbook listings can lag renewals, so always confirm the number printed on the pack. Because it is drawn from the live register, this is far more complete than a typical brand list.

6 companies hold active Isoniazid registrations in the NAFDAC Greenbook. They include Onifam Laboratories, Embassy Pharmaceutical and Chemicals, Healthline, Interpharma Industries. The "applicant" recorded in the Greenbook is the registration holder — usually the manufacturer or its Nigerian representative — and the full table above shows the applicant for every registered product.

Each brand here holds a NAFDAC registration in the Greenbook. However, counterfeiters sometimes copy a genuine NAFDAC number onto a fake product, so always confirm that the brand, manufacturer (applicant), and strength printed on the pack match the record before you buy, and purchase only from licensed pharmacies.

Isoniazid brand prices in Nigeria vary by brand, strength, and where you buy it — imported brands are often more expensive than locally manufactured ones. Confirm the current price with a licensed pharmacy, and see the price guide on the main Isoniazid page.
