1. What is Ethambutol and what is it used for
Ethambutol is an anti-tuberculosis medicine. It inhibits the growth and causes the death of the bacteria that cause tuberculosis in humans and animals, as well as some atypical mycobacteria that cause mycobacteriosis.
Ethambutol is used in combination with other anti-tuberculosis medicines, as it causes rapid development of resistance when used alone.
Indications for use:
In combination with other anti-tuberculosis medicines:
- pulmonary and pleural tuberculosis (primary and secondary infections);
- extrapulmonary tuberculosis (meningitis, bone and joint, genitourinary, nerve root).
The medicine can only be used to treat tuberculosis caused by microorganisms sensitive to ethambutol.
2. Important information before taking Ethambutol

Warnings and precautions
Before starting treatment with Ethambutol, discuss it with your doctor or pharmacist.
Before and during treatment with ethambutol, the doctor will recommend regular ophthalmological examinations: examination of the fundus, visual field, visual acuity, and color vision. The control examination should include each eye separately and both eyes together. If doses greater than 15 mg/kg are administered, eye examinations should be performed at least once a month. Special ophthalmological control, due to the more difficult subjective and objective assessment of vision disturbances during ethambutol therapy, the doctor will cover patients with eye diseases: cataracts, inflammation within the eyeball, diabetic retinopathy. The patient must remember to self-monitor visual acuity and color vision, and in case of any disturbances, stop treatment and consult a doctor.
Ethambutol may cause decreased visual acuity and color perception. These disturbances may be related to the dose used and the duration of treatment. They usually disappear if the medication is stopped immediately after they are observed. However, irreversible blindness has also been reported.
In children, the doctor will recommend regular ophthalmological examinations.
Ethambutol can harm the liver, and even fatal cases have been observed.
The doctor will recommend regular examinations of kidney, liver, and hematopoietic system function.
During treatment with ethambutol, acute gout attacks may occur.
When to exercise special caution when taking Ethambutol:
In connection with the use of Ethambutol, severe skin reactions have been reported, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS). You should stop taking Ethambutol and immediately consult a doctor if you experience any symptoms associated with these severe skin reactions, described in section 4.
Children and adolescents
Ethambutol should not be given to children under 13 years of age, as its safety in this age group has not been established.
Patients with kidney function disorders
In patients with kidney function disorders, the medicine may accumulate in the body, so the doctor will adjust the dosage accordingly.
Elderly patients
Caution should be exercised when using this medicine in this age group. Usually, the doctor will start with the lowest doses in the recommended range, taking into account the higher frequency of liver, kidney, or heart function disorders, as well as other concomitant diseases or ongoing therapies.
Ethambutol and other medicines
Tell your doctor or pharmacist about all medicines you are taking, have recently taken, or plan to take.
Aluminum hydroxide reduces the absorption of ethambutol from the gastrointestinal tract, so it is recommended to maintain a 4-hour interval between taking ethambutol and taking an antacid containing aluminum hydroxide.
Ethambutol may interact with phentolamine, causing a false-positive result in the test for pheochromocytoma.
Ethambutol with food and drink
The medicine can be taken independently of meals; it is recommended to drink it with a glass of water.
Pregnancy and breastfeeding
If you are pregnant, breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor or pharmacist before taking this medicine.
The use of the medicine during pregnancy is contraindicated.
Ethambutol passes into breast milk, and breastfeeding is not recommended during treatment.
Driving and using machines

3. How to take Ethambutol
Always take this medicine exactly as your doctor or pharmacist has told you.
In case of doubt, consult your doctor or pharmacist.
The doctor may use different treatment regimens for tuberculosis using ethambutol.
Ethambutol can be used simultaneously with other anti-tuberculosis medicines, such as cycloserine, ethionamide, pyrazinamide, and viomycin.
In combination therapy, ethambutol can also be used with isoniazid, aminosalicylic acid, and streptomycin.
The following are the usual dosages.
Use in adults and children over 13 years of age
Initial treatment – in patients who have not been previously treated with anti-tuberculosis medicines
From 15 to 25 mg/kg body weight per day in a single dose.
In these patients, the most commonly used regimens are: ethambutol + isoniazid or ethambutol + isoniazid + streptomycin.
Retreatment – in patients who have been previously treated with anti-tuberculosis medicines
From 20 to 25 mg/kg body weight per day in a single dose, in combination with at least one tuberculostatic medicine to which the bacteria are sensitive in vitro. After 60 days, the dose should be reduced to 15 mg/kg body weight per day in a single dose.
Intermittent treatment
50 mg/kg body weight per day in a single dose, 1 or 2 times a week.
Use in patients with kidney function disorders
Since the kidneys are the main route of elimination of ethambutol, the doctor will adjust the dosage as follows:
| Glomerular filtration rate (GFR) <50 | Dose in mg/kg body weight | Dosing interval |
| >25 ml/min | 15-25 | every 24-36 hours |
| 10-25 ml/min | 7.5-15 | every 48 hours |
| <10 ml min or patients on dialysis< td> | 5 | every 48 hours |
