This medication is given by injection into a muscle or infused into a vein over 1 hour, usually by a health care professional. It is given as directed by your doctor, usually once a day for 2 to 4 months then reduced to 2 or 3 times a week. The dosage is based on your medical condition and response to treatment.

If you are using this medication at home, learn all preparation and usage instructions from your health care professional. If you have any questions about using this medication properly, ask your health care professional. Before using this product, check it visually for particles. When mixed, this medication may be nearly colorless or very pale yellow. The color may darken over time, but this does not make this medication less effective. If the liquid has particles or has changed to any other color than pale or dark yellow, do not use it.

If you are giving this medication by injection into a muscle, remember to change the injection site with each dose to prevent irritation. Also, inject this medication into a large muscle such as the buttock or thigh to lessen pain from the injection.

Continue to use this medication until the full prescribed amount is finished, even if symptoms disappear. Stopping the medication too early may result in a return of the infection. It may be necessary to continue treatment for TB for 1 to 2 years. If needed, your doctor may switch you to a drug for this same condition that can be taken by mouth.

For the best effect, use this antibiotic at evenly spaced times. To help you remember, use it on the same day(s) of the week or at the same time each day, depending on your doctor's instructions. If you are using this medication several times a week, it may help to mark your calendar with a reminder.

Do not use more or less of this drug than prescribed or stop using it (or other TB medicines) even for a short time unless directed to do so by your doctor. Skipping or changing your dose without approval from your doctor may cause the amount of TB bacteria to increase, make the infection more difficult to treat (resistant), or worsen side effects. If TB becomes resistant to this medication, it might also become resistant to other TB medications.

Learn how to store and discard needles, medical supplies, and any unused medication safely. Never reuse needles or syringes.

Tell your doctor if your condition lasts or gets worse.
