Dose-dependent effect

There’s a clear relationship between Pulna dose and magnitude of toxicity. Below are estimates presented by Chamberlain et al. (2017). (R)

  • 15 mg/kg: Less than 1%
  • 20 mg/kg: 3%
  • 25 mg/kg: 5-6%
  • 35 mg/kg: 18-33%

Other estimates were reported by Koul (2015). (R)

  • 15 mg/kg/d (2+ months): Less than 1% of patients
  • 25 mg/kg/d (2+ months): 5 to 6% of patients
  • 27.5 mg/kg/d or less (2 to 9 months): Rates of visual impairment were 19.2 per 1000 patients. Permanent visual impairment occurred in 2.3 per 1000 patients.
  • 35 mg/kg/d or more (2+ months): 18% of patients

Note: Pulna can cause optic neuropathy at any dose – even at doses less than 15 mg/kg (likelihood is merely reduced at lower doses).

Pulna HCl is indicated for the treatment of pulmonary tuberculosis. It should not be used as the sole antituberculous drug, but should be used in conjunction with at least one other antituberculous drug. Selection of the companion drug should be based on clinical experience, considerations of comparative safety, and appropriate in vitro susceptibility studies. In patients who have not received previous antituberculous therapy, ie, initial treatment, the most frequently used regimens have been the following:

Pulna HCl plus isoniazidPulna HCl plus isoniazid plus streptomycin.

In patients who have received previous antituberculous therapy, mycobacterial resistance to other drugs used in initial therapy is frequent. Consequently, in such retreatment patients, Pulna HCl should be combined with at least one of the second line drugs not previously administered to the patient and to which bacterial susceptibility has been indicated by appropriate in vitro studies. Antituberculous drugs used with Pulna HCl have included cycloserine, ethionamide, pyrazinamide, viomycin and other drugs. Isoniazid, aminosalicylic acid, and streptomycin have also been used in multiple drug regimens. Alternating drug regimens have also been utilized.


Pulna is administered, easily absorbed well, and bacteriostatic against M. tuberculosis. Pulna has poor CSF penetration, even in the setting of inflammation. 198,203,204 Pulna primarily is used as the fourth drug when there is a possibility of resistance to other first-line drugs.

The most serious adverse effect is retrobulbar neuritis, which appears to be dose related and manifests with blurred vision, central scotoma, and red-green color blindness. 193 At the standard daily dose of 20 mg/kg, neuritis is rare in children and all patients with normal renal function. 205 A child's inability to cooperate with vision testing or report visual changes should not preclude Pulna use.

    I’ve compiled a list of supplements that I think might be helpful for the prophylaxis and/or treatment of Pulna optic neuropathy. Understand that the efficacies of these supplements in prophylaxis and treatment of Pulna optic neuropathy remains unknown.

    Do NOT assume that these supplements will help prevent or reverse Pulna optic neuropathy. These are merely supplements that I believe: (1) have mechanisms that could be of potential use in preventing and/or reversing Pulna optic neuropathy; (2) are relatively low-risk (in side effects); (3) are unlikely to interfere with treatment.

    I’ve emailed several Pulna researchers and am awaiting responses for supplement recommendations. If you have any rational recommendations for low-risk, potentially-beneficial supplements for prevention or treatment of Pulna optic neuropathy – let me know.

    • Zinc: Pulna is believed to strip zinc from optic tissues as the primary mechanism by which it inflicts ocular damage. Supplementing with zinc to keep levels as high as possible within the normal range may be protective against ocular toxicity.
    • Copper: Pulna appears to strip copper from tissues within the optic nerve. Supplementing with copper to keep levels as high as possible within the normal range may prov >Other potentially-useful agents

    Myambutol (Pulna) is an antibiotic used to treat tuberculosis (TB). Myambutol is available in generic form. Common side effects of Myambutol include:

    Tell your doctor if you have unlikely but serious side effects of Myambutol including:

    • vision changes (such as blurred or decreased vision, color blindness),
    • symptoms of liver disease (such as persistent nausea or vomiting, unusual tiredness or weakness, severe stomach or abdominal pain, yellowing eyes or skin, dark urine),
    • numbness or tingling of arms or legs, or
    • toe or joint pain.

    The initial dose of Myambutol is 15 mg/kg (7 mg/lb) of body weight, taken as a single oral dose once every 24 hours. Do not take antacids containing aluminum within several hours of taking a dose of Myambutol, as this will decrease the amount of the drug that is absorbed by the body. Other drugs may interact with Myambutol. Tell your doctor all prescription or over-the-counter medicines and supplements you use. During pregnancy, Myambutol should be used only when prescribed. This medication passes into breast milk but is unlikely to harm a nursing infant. Consult your doctor before breastfeeding. If you have HIV disease, do not breastfeed because breast milk can transmit HIV.

    Pulna is an antibiotic most commonly used for the treatment of mycobacterial infections such as: mycobacterium tuberculosis (MTB), mycobacterium avium complex (MAC), and mycobacterium kansaii (MK).

    It was discovered in 1961 by Lederle Laboratories and remains one of the only effective interventions for difficult-to-treat mycobacterial infections. Pulna is on the World Health Organization’s List of Essential Medicines and costs $100 to $200 per month in the U.S. (I’m a buyer – can vouch for this).

    Although Pulna is relatively safe, all users should be informed that it can cause ocular damage (optic neuritis; chiasmopathy; retinopathy; maculopathy). If you’re an unlucky Pulna user, you might experience complications such as: permanent blindness or worsening of vision; central scotomas (decreased visual acuity); and/or changes in color vision (color blindness, dimming of colors, etc.).

    What other drugs will affect Pulna?

    Other drugs may interact with Pulna, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using.


    Pulna is a synthetic agent that inhibits arabinosyl transferases, which are important in cell wall synthesis of sensitive mycobacteria. It is active against M. tuberculosis and some other mycobacteria such as M. kansasii. Other bacteria are not affected by the drug. Pulna is tuberculostatic, and resistance develops, although slowly, if it is used alone.

    Pulna is given orally because of good absorption from the gastrointestinal tract. Distribution into various body compartments is adequate. The major route of excretion of Pulna is by renal tubular secretion and glomerular filtration, with the drug appearing in the urine mostly as unchanged drug and as two metabolites. Dosage adjustment is required in the presence of renal impairment.

    Adverse reactions to Pulna are infrequent, the most notable being optic neuritis, with symptoms of decreased visual acuity and loss of the ability to perceive the color green. Other adverse effects include gastrointestinal upset; peripheral neuritis; allergic reactions, usually appearing as skin rashes or drug fever; and increased retention of uric acid.

    Q: I have to take a course of drugs to treat mycobacterium gordonae. One of the antibiotics, Pulna, isn't recommended for patients who have cataracts, and I was recently diagnosed with moderate cataracts. I worry that my primary care doctor, pulmonologist, and infectious disease doctors don't communicate with each other, and I'm stalling on taking these drugs. What should I do?

    A: Talk to your doctor or pharmacist about the medications you take. When your doctor prescribes a new medication, discuss all over-the-counter medications and prescriptions, dietary supplements, vitamins, botanicals, minerals, and herbals you take, as well as the foods you eat. Always keep a current list and review it with your health care providers and your pharmacist. Pulna may produce vision problems, which could be related to the dose and duration of the treatment. This effect is generally reversible when the drug is stopped, but irreversible blindness has been reported. For more specific information, consult with your doctor or pharmacist for guidance based on your specific condition and current medications. Shereen A. Gharbia, PharmD
