FAQ

Ethambutol tablets are prescription-only medicines in UK pharmacies. However, our store policy allows Myambutol to be ordered without a prescription and sent by mail. Tuberculosis treatment should be managed by a specialist TB team.

No. Ethambutol is used as part of combination treatment for active tuberculosis, and symptoms may improve before the infection has been fully treated. Continue the prescribed regimen unless the clinician managing the treatment tells you to change or stop it; stopping early can contribute to treatment failure and drug resistance.

The regulatory status of the exact product supplied cannot be confirmed from the catalogue information alone, as this depends on the identified manufacturer, strength and presentation. In the United Kingdom, ethambutol hydrochloride tablets are prescription-only medicines, but that does not verify the authorisation status of a particular supplied pack.

Myambutol contains ethambutol, an antitubercular medicine used to treat active tuberculosis. It is used together with other tuberculosis medicines, rather than on its own, to help prevent resistance and improve treatment effectiveness.

Myambutol tablets are taken by mouth as part of a combination tuberculosis regimen. The dose is selected by the treating clinician, usually according to body weight and kidney function. They may be taken with food if they cause stomach upset; avoid taking aluminium hydroxide antacids at the same time, as they can reduce ethambutol absorption.

Description

Myambutol

Dosage Form

Capsules, tablets, coated tablets.

How Does the Drug Work?

TB drugs: They get into actively growing mycobacterial cells, inhibiting the synthesis of RNA, affecting cell metabolism, and causing cessation of reproduction and death of bacteria. They are active just against actively dividing cells. They suppress the growth and multiplication of Mycobacterium tuberculosis, which is resistant to ethionamide, Pasco, kanamycin, isoniazid, and streptomycin. When monotherapy, the resistance of mycobacteria develops quite fast.

Indications

Tuberculosis (all forms).

Contraindications

Hypersensitivity, pregnancy, children up to 13 years, cataract, optic neuritis, inflammatory eye diseases, gout, renal failure, lactation.

Side Effects

From the nervous system and sensory organs side:

hallucinations, depression, headache, weakness, disorientation, peripheral neuritis (paresthesias in the extremities, numbness, paresis, and itching), dizziness, altered mental status, optic neuritis (decrease in visual acuity, breach of color perception, mostly green and red colors, color blindness, scotoma).

From the digestive system:

loss of appetite, nausea, stomachodynia, vomiting, abnormal liver function - increase in the activity of "liver" of transaminases.

Allergic reaction:

itching, arthralgia, skin rash, fever, dermatitis, anaphylaxis.

Other:

hyperuricaemia, exacerbation podagry.

How to Use the Medicine? Dosage

Orally.

When administering the initial medication, the dosage is 15 mg/kg 1 time a day. In the conduct of re-treatment - 25 mg/kg 1 time a day for 2 months, then move on to 15 mg/kg 1 time a day.

Children - 20-25 mg/kg once, after breakfast.

The maximum daily dose is 2 g. In renal failure, the dose is adjusted depending on QA: QA with more than 100 ml/min, daily dose-20 mg/ kg, 70-100 ml/min - 15 mg/kg, less than 70 ml/min - 10 mg/kg, in people who are on hemodialysis-5 mg/kg, on day of dialysis-7 mg/kg.

Cautions

At the beginning of treatment, there may be an increased cough and an increase in sputum. Assigned just in combination with other anti-LS. When conducting long-term therapy, one must regularly monitor the function of the organ of vision, a picture of the peripheral blood, and the functional state of the liver and kidneys. During the treatment period, you must pay attention while driving vehicles and engaging in other potentially hazardous activities requiring high attention concentration and quickness of psychomotor reactions.

Interaction

Increases the effects of anti-LS, neurotoxicity of imipenem, ciprofloxacin, carbamazepine, methotrexate, quinine, asparaginase, aminoglycosides, salts of Li +.

Where to Keep the Drug?

To keep in a dark place.

In treating tuberculosis, Myambutol is an essential tool since it successfully inhibits bacterial growth while having tolerable side effects. Nonetheless, it is crucial to keep a watchful eye out for any potential risks. Following thorough treatment programs is critical to achieving the best possible results in the ongoing fight against tuberculosis.

Warning: Before starting to take the drug, you need to consult your doctor.

Customer questions

Asked by Emily Carter, Portsmouth, United Kingdom

I'm ordering from Portsmouth. Will the Myambutol pack include an English leaflet?

Answered by Support team

The leaflet language for the supplied pack cannot be guaranteed in advance. Please check the package label and enclosed instructions on arrival, and use a pharmacist or clinician for help before taking the tablets if any instructions are not clear.

Asked by Hannah Williams, Manchester, United Kingdom

I'm breastfeeding and my TB team has included ethambutol in my treatment. Can I continue breastfeeding?

Answered by Support team
Medical reviewed by Spencer Hughes

Ethambutol passes into breast milk in low amounts, and UK guidance generally considers the amount too small to harm a breastfed baby. Your TB team should still oversee treatment and advise on observing the baby, as breast-milk exposure does not treat or prevent TB in an infant.
