What is a generic medication?

Generic medications are significantly discounted copies of brand name medication that have the same active ingredients, intended use, dosage, side effects, effects, and route of administration as the original brand name medication. In other words, generic medications have the same pharmacological effects as their brand-name counterparts. Over half of all prescribed medications are for generic medications.

  • Isoniazid Overview

    Isoniazid is used with other medications to treat active tuberculosis (TB) infections. It is also used alone to prevent active TB infections in people who may be infected with the bacteria (people with positive TB skin test). Isoniazid is an antibiotic and works by stopping the growth of bacteria. This antibiotic treats only bacterial infections. It will not work for viral infections (such as common cold, flu). Using any antibiotic when it is not needed can cause it to not work for future infections.

  • Isoniazid Warnings

    Isoniazid has rarely caused very serious (possibly fatal) liver disease. The risk of liver disease is increased in people who are 35 years and older, who use alcohol or illegal injection drugs, or who currently have long-term liver problems. Tell your doctor right away if you develop symptoms of liver disease, including nausea/vomiting that doesn't stop, severe stomach/abdominal pain, unusual weakness/tiredness, dark urine, yellowing eyes/skin. Your doctor should order liver function tests while you are taking Isoniazid. Keep all medical and laboratory appointments.

  • How to Use Isoniazid

    Take Isoniazid by mouth on an empty stomach (1 hour before or 2 hours after meals) as directed by your doctor. If you are using the liquid form of Isoniazid, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. If you also take antacids that contain aluminum, take Isoniazid at least 1 hour before the antacid. Dosage of Isoniazid is based on your age, weight, medical condition, and response to treatment. For the best effect, take Isoniazid at evenly spaced times. If you are taking Isoniazid daily, take it at the same time each day. If you are taking Isoniazid on a weekly schedule, take it on the same day(s) of the week and at the same time each day. Mark the days on the calendar when you need to take the medication. Continue to take Isoniazid (and other TB medications) until the full prescribed amount is finished, even if symptoms disappear. Stopping the medication too early or skipping doses may allow the bacteria to continue to grow, which may result in a return of the infection and cause the infection to be more difficult to treat (resistant). Your doctor may also direct you to take vitamin B6 (pyridoxine) to help prevent certain side effects (such as nerve problems) from isoniazid. Follow your doctor's instructions carefully. Isoniazid may interact with foods containing tyramine/histamine (such as cheese, red wine, certain types of fish). This interaction may cause increased blood pressure, flushing of the skin, headache, dizziness, or fast/pounding heartbeat. Tell your doctor right away if any of these symptoms occur. Your doctor may recommend that you follow a special diet while taking Isoniazid. Consult your doctor for more details. Tell your doctor if your condition lasts or gets worse.
