Neosporin vs Polysporin in detail
Antibiotics or anti-bacterials are a key aspect of treatment for a range of conditions and illnesses. They are a type of antimicrobial drug used in the treatment and prevention of bacterial infections. They are therefore used when it is likely that bacteria can cause infection in some part of the body. One such instance is the occurrence of cuts, scrapes and other minor wounds. Antibiotic gels and creams are among the first things to be applied after cleaning the wound. Of course, there are many options to choose from and it can be difficult to know which ones to pick.
Two of the most popular topical antibiotics are Neosporin and Polysporin. Both are effective in speeding up the healing process but there are some differences in their ingredients and chemical compositions. These are important to note since you want to avoid causing complications or making a minor injury become something more serious. Here is a comparison between Neosporin and Polysporin in relation to their antibacterial activity, pain relieving properties and potential side effects.
Neosporin’s effectiveness comes from neomycin sulfate, polymyxin B, and bacitracin zinc. which work together to destroy bacteria. Polysporin contains the same antibiotic agents except for neomycin sulfate. Instead, it contains gramicidin which is also effective against bacteria.
Despite Neosporin’s bacteria-fighting capabilities, many people are allergic to the neomycin it contains. Neomycin frequently causes contact dermatitis. The outer layers of the skin become inflamed, red, dry and scaly. The bacitracin in Polysporin can also trigger allergies but the likelihood is significantly lower than that associated with Neomycin. People who are allergic to Neosporin may, therefore, be prescribed Polysporin. In fact, Polysporin is often the first choice and Neosporin is only used if other options do not work.
Both antibiotic preparations contain pain relieving agents. Neosporin contains the pain-relieving agent pramoxine which helps to reduce the pain that usually comes with cuts, scrapes, and burns. It offers temporary relief from discomfort. Polysporin, on the other hand, contains Lidocaine hydrochloride which delivers rapid pain relief.
Neosporin should not be used for more than a week. If your wound does not get better within seven days, you should stop using the product and speak to your doctor since you may be need a stronger medication.
The effectiveness of antibiotic treatments for wounds is well established and both Neosporin and Polysporin show similar levels of success for minor injuries. The only reason Polysporin may have the edge over Neosporin is that more people are allergic to Neomycin. Neither preparation is particularly suited to large or deep cuts and should only be used in the case of minor injuries.
