Lymphedema and Neosporin

There has recently been a flurry of comments being posted about lymphedema patients using neosporin as a topical antibiotic medicine. Indeed, one website even put out a page advising patients not to use it at all because of a possible allergy to it.

While it is a fact that apparently 20% of the population is allergic to it. In all the panic, however,I would like to offer what I feel is a more common sense approach to this.

As of this update of Jan 19, 2012, I have heard of no further problems with Neosporin. I am still not understanding what the big fuss was/is. Clinically speaking, no more people are allergic to this ointment then others.

Types of lymphedema wounds

First, we really need to differentiate between the types of wounds that we might be using Neosporin on.

There are wounds caused by accidents such a cuts, scratches, scrapes and the like.

Wounds that Drain Lymphorrhea

Those of us with lymphedema also get these open draining areas that we commonly refer to as a wound. These areas drain a fluid called lymphorrhea.

I'm not at all convinced that an antibiotic ointment is even call for with these draining areas. What is needed on these spots is a topcial that (1) protects the surrounding skin (2) heals the heal. That is why I personally use baby diaper lotion/ointment with zinc oxide. Zinc is a clinically proven agent that promotes skin health.

Also, what so many lymphers forget is that type of wound simply must have consistent and continual compression generally provided by our short-stretch bandages. If we do not wrap the leg/arm then it swells more. This additional swelling acts to pull apart the skin tissue that is trying to regrow. A lymphedema wound is only going to get worse unless this compresion is used.

Injury Wounds

The other type of wound we get is caused by an injury. This includes cuts, scratches, scrapes and punctures.

These wounds after being thoroughly cleaned generally do need a topical antibiotic ointment. It is imperative that these wounds be kept absolutely clean as any bacteria allowed to enter could develop very quickly intot a life-threatening case of cellulitis.

Most of these wounds are superficial and can easily be treated by us. If it is a serious wound, we really ought to get to the doctor too and not try to treat it ourselves.

To use Neosporin or not to use

I think the answer to that question is actually quite easy.

If you have never reacted to it, then I see no reason to stop using it. I have never reacted to using it - have used it for many many years - and will continue to do so. For me, it is totally safe.

If you know you do have an allergy then of course, just don't start using it. Simple, but basic common sense.

If you don't know, there is something you might try. Put a dab - and I mean a dab - on your skin (never on the limb with LE). If you start a reaction, then (1) wash it off immediately (2) never use it.

Neosporin is a Medicine

Remember, Neosporin is a medicine in a class called Polypeptide antibiotics and always should be respected and used as such. It has is a combination product containing Neomycin Sulfate, Bacitracin Zinc, and Polymyxin B Sulfate. For those of us who use it, we need to follow the guidelines and protocols for its use.

Neosporin Information

Description

Neosporin OPHTHALMIC OINTMENT (neomycin and polymyxin B sulfates and bacitracin zinc ophthalmic ointment) is a sterile antimicrobial ointment for ophthalmic use. Each gram contains: neomycin sulfate equivalent to 3.5 mg neomycin base, polymyxin B sulfate equivalent to 10,000 polymyxin B units, bacitracin zinc equivalent to 400 bacitracin units, and white petrolatum, q.s.

Neomycin sulfate is the sulfate salt of neomycin B and C, which are produced by the growth of Streptomyces fradiae Waksman (Fam. Streptomycetaceae). It has a potency equivalent of not less than 600 µg of neomycin standard per mg, calculated on an anhydrous basis.

Clinical Parhmacology

A wide range of antibacterial action is provided by the overlapping spectra of neomycin, polymyxin B sulfate, and bacitracin.

Neomycin is bactericidal for many gram-positive and gram-negative organisms. It is an aminoglycoside antibiotic which inhibits protein synthesis by binding with ribosomal RNA and causing misreading of the bacterial genetic code.

Polymyxin B is bactericidal for a variety of gram-negative organisms. It increases the permeability of the bacterial cell membrane by interacting with the phospholipid components of the membrane.

Bacitracin is bactericidal for a variety of gram-positive and gram-negative organisms. It interferes with bacterial cell wall synthesis by inhibition of the regeneration of phospholipid receptors involved in peptidoglycan synthesis.

Microbiology: Neomycin sulfate, polymyxin B sulfate, and bacitracin zinc together are considered active against the following microorganisms: Staphylococcus aureus, streptococci including Streptococcus pneumoniae, Escherichia coli, Haemophilus influenzae, Klebsiella/Enterobacter species, Neisseria species, and Pseudomonas aeruginosa. The product does not provide adequate coverage against Serratia marcescens.

Effect of combined chlorhexidine gluconate and Neosporin on experimental keratitis with two pathogenic strains of Acanthamoeba.

Dec. 2011

Akin Polat Z, Vural A. Source Department of Medical Parasitology, Cumhuriyet University School of Medicine, 58140, Sivas, Turkey, zubeydeakin@yahoo.com. Abstract Acanthamoeba keratitis (AK) is a painful, sight-threatening, and difficult-to-treat corneal infection caused by the ubiquitous free-living amoebae Acanthamoeba species. The aim of the present study was to compare the severity of keratitis, caused by Acanthamoeba hatchetii and Acanthamoeba castellanii infections, and to assess the therapeutic effects of combined chlorhexidine (CHX) and Neosporin® treatment in rats. The rats were first divided into two groups, in which the eyes of the animals were infected with A. hatchetii or A. castellanii trophozoites. On day 5, all corneas were examined in order to determine the degree of infection (grade 0 to 3), and animals were divided into two new groups, treatment and infected control groups. The treatment was continued for 28 days, followed by excision and histological evaluation of the corneas. In conclusion, the clinical picture progressed more rapidly and severely in eyes infected by A. castellanii, while it was non-invasive and slower to progress with A. hatchetii. Moreover, eyes infected by A. hatchetii responded quicker and more positively to therapy, consistent with its clinical course, while a longer recovery was seen with A. castellanii. Histological examinations revealed the presence of A. castellanii and A. hatchetii trophozoites in the stroma of eyes of the treatment and control groups. As a result, our findings suggest that a combination of Neosporin with lower doses of CHX may be beneficial to treat patients with early diagnosis of AK.
