The dose of ethambutol depends on body weight and will be determined by your doctor.

For adults and children 13 years of age and over who have not used ethambutol before, the recommended dose is 15 mg per kilogram of body weight once daily (to a maximum of 2.5 g).

For adults and children aged 13 years and older who have used ethambutol before, the recommended dose is 25 mg per kilogram of body weight once daily. After 60 days of treatment, or when the infection clears up, the dose can be decreased to 15 mg per kilogram of body weight once daily.

When ethambutol is used in combination with other tuberculosis medications, a dose of 50 mg per kilogram of body weight (to a maximum of 2.5 g) can be taken twice a week. Alternatively, ethambutol can be used at a dose of 25 mg per kilogram of body weight to 30 mg per kilogram of body weight (to a maximum of 2.5 g) 3 times a week.

Children's dosage: Dosage has not been established for children less than 13 years of age but your doctor may consider ethambutol for children under 13 years, especially if other tuberculosis medications have not worked. It is not recommended for children whose visual changes cannot be monitored (e.g., children younger than 6 years of age).

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Ethambutol must be taken for the recommended duration of treatment, even if you are feeling better. This will reduce the chances of having remaining bacteria grow back.

Ethambutol can be taken with or without food. It should be taken as a single daily dose, at the same time each day, and preferably in the morning.

Ethambutol should never be used on its own and should always be used in combination with other tuberculosis medications.

It is important to take this medication exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store this medication at room temperature; protect it from light, moisture, and excessive heat; and keep it out of the reach of children.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Eye problems: Ethambutol may cause eye problems associated with inflammation of the optic nerve such as decreased vision and loss of red-green colour vision. Normal vision is usually restored within weeks or months of stopping the medication. Your doctor will recommend monthly eye examinations, especially if you are receiving a daily dose greater than 15 mg per kilogram of body weight, have kidney problems, or have other eye problems (e.g., cataracts).

Gout: Some people taking ethambutol have experienced an increase of uric acid in the blood, causing gout. Symptoms of an acute gout attack include sudden pain, swelling, and stiffness in the affected joint, often the big toe. You may also experience a fever. If this is your first attack, seek medical attention as soon as possible. If you have had gout attacks before, follow your doctor's instructions for dealing with the attack.

Kidney disorders: People with kidney disease or reduced kidney function should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Liver disorders: People with liver disease or reduced liver function should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Pregnancy: Ethambutol is considered to be safe for use by pregnant people.

Breast-feeding: Ethambutol passes into breast milk, but it is considered to be safe for use by those who are breast-feeding.

Children: The safety and effectiveness of using this medication have not been established for children under 13 years of age. Dosage has not been established for children under 13 years of age but your doctor may consider ethambutol for children under 13 years, especially if other tuberculosis medications have not worked. Because ethambutol can cause vision problems, it is not recommended for children whose visual changes cannot be monitored (e.g., children younger than 6 years of age).

If you are taking other medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:

• stop taking one of the medications,

• change one of the medications to another,

• change how you are taking one or both of the medications, or

• leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.
