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 Drug Information

  • 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 persistent nausea/vomiting, 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 persists or worsens.

  • Isoniazid Precautions

    Before taking isoniazid, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. Isoniazid may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details. Before using Isoniazid, tell your doctor or pharmacist your medical history,previous severe reaction from isoniazid (such as liver disease), liver disease, alcohol use, HIV infection, kidney disease, diabetes, numbness/tingling of arms/legs (peripheral neuropathy), recent childbirth. Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Alcohol may increase the risk of liver disease. Avoid alcoholic beverages while using Isoniazid. Isoniazid may cause live bacterial vaccines (such as BCG vaccine) to not work as well. Therefore, do not have any immunizations/vaccinations while using Isoniazid unless your doctor tells you to. Liquid forms of Isoniazid may contain sugar. Caution is advised if you have diabetes or any other condition that requires you to limit/avoid sugar. Ask your doctor or pharmacist about using Isoniazid safely. During pregnancy, Isoniazid should be used only when clearly needed. Discuss the risks and benefits with your doctor. Isoniazid passes into breast milk but is unlikely to harm a nursing infant. Consult your doctor before breast-feeding.

  • Isoniazid Misdose

    For the best possible benefit, it is important to take each scheduled dose of Isoniazid as directed. If you are taking Isoniazid daily and miss a dose, take it as soon as you remember. If it is near the time of the next dose, skip the missed dose. Take your next dose at the regular time. Do not double the dose to catch up. If you are taking Isoniazid on a weekly schedule and miss a dose, take it as soon as you remember if it is on the same day. If you remember on the next day or later, contact your doctor or pharmacist right away to establish a new dosing schedule. Do not double the dose to catch up.

  • Isoniazid Side Effects

    What are Isoniazid side effects?

    Side effects are physical, mental or emotional symptoms which occur in addition to or outside of the desired effect of a therapeutic treatment such as an over-the-counter or prescribed drug or medication. Side effects from Isoniazid may occur at the beginning or at the end of treatment and may also depend on the length of time an individual remains on the treatment. Side effects, also known as adverse effects, are generally more likely to occur when starting treatment. Individuals may also experience side effects from Isoniazid as a result of an interaction with other medications.

    Side Effects of Isoniazid

    The side effects of Isoniazid may vary in number and intensity for many different reasons. Factors such as age, weight, gender and ethnicity may influence the side effects of Isoniazid. Also, an individual’s state of general physical health and seriousness of the disease or illness as well as an increase or decrease in dosage may lead to side effects. Further, side effects from Isoniazid may also occur as a result of an interaction with certain herbal supplements, foods or drinks.

    Prescription drug side effects can be serious and may cause patients to stop the treatment. However, when side effects from the use of a prescription drug, such as Isoniazid, do occur a patient should consult their physician. A physician may prescribe an additional treatment in order to control the symptoms or an adjustment in the dosage may be made. In addition, changes to diet, exercise or other lifestyle activities may help to lessen the side effects of Isoniazid.

    By understanding side effects and the factors which may influence the occurrence of side effects patients are empowered to take an active role in their care. Patients who have specific questions about the side effects of Isoniazid, or any other medication, should contact their physician.
