How Long Does Neosporin Last?

If you have ever had a minor cut, applying Neosporin can help keep it from becoming infected.

However, if the wound is larger or deeper than what can be treated at home, then seeking medical help is recommended.

As with all medications, neosporin has an expiration date printed on its packaging. Once expired, however, the potency of active ingredient drops drastically – potentially leading to decreased health benefits and antibiotic resistance.

Expiration date

Neosporin is a widely-used antibacterial ointment. It’s perfect for treating minor cuts, scrapes and burns – so it’s no surprise that you may already have a tube in your medicine cabinet.

However, just like any other medicine, first aid ointments have an expiration date printed on their packaging. In general, over-the-counter first aid ointments last 2 to 3 years from manufacturing date; so always double check these dates before using them.

Another essential thing to be mindful of when taking medications is their expiry date. Expiring drugs, particularly antibiotics, may lead to more severe infections or the development of antibiotic resistance. Be sure to discard them promptly upon expiration for maximum effectiveness.

The FDA strongly suggests replacing drugs that have passed their expiration date with new ones to maximize their benefits. Furthermore, regularly inspecting medicine cabinets for expired items like neosporin can help ensure you don’t end up with a bottle that’s no longer effective or contains bacteria.

In addition to the expiration date, it’s essential to remember that ointments can lose their effectiveness over time due to exposure to heat and humidity or poor storage conditions. If your tubes of Neosporin have been sitting in your bathroom for too long or have an open or unclosed tube, consider replacing them immediately! Be sure to check the expiration date before using anything!

Be mindful that neosporin, in particular, has the potential for becoming toxic over time. While it’s unlikely you will develop an allergy to it, if you do, immediately cease applying the cream onto your skin and contact your doctor for further assistance.

In honor of Earth Day’s 40th anniversary, NEOSPORIN has joined forces with TerraCycle to offer families an eco-friendly way to dispose of their expired ointments. For more information, they invite you to visit their website.

Shelf life

Neosporin is an antibiotic ointment commonly used to treat minor cuts and scrapes. It contains the antibiotics bacitracin, neomycin, and polymyxin B that work together to eliminate bacteria responsible for infection.

Neosporin can still be safely used after expiration, though it may not be as effective at killing bacteria in wounds as fresh ointment would. Furthermore, expired cream is more likely to have become contaminated with bacteria which could lead to infection.

Expired Neosporin may still be useful in certain circumstances, particularly for people caught up in survival scenarios where fresh medicine is unavailable. First aid becomes especially important during such times and Neosporin can be an invaluable aid when treating injuries or cuts.

John Tomaka, M.D. – an emergency-room doctor at Providence Saint Vincent Medical Center in Los Angeles – says that in times of dire need, it can be difficult to find time to shop for fresh medicines for wounds or cuts. That is when using an ointment that has already passed its expiration date can come in handy, according to Dr. Tomaka.

An expired tube of Neosporin can be used on wounds that are still red and bleeding or dirty after washing them. However, you should not use this ointment on large cuts or burns that go deep, or if you have chronic skin conditions.

Therefore, it’s always recommended to use fresh Neosporin when treating a wound. An expired ointment may be less effective and hazardous to your health, plus it’s harder to apply evenly.

When determining whether an expired ointment can still be used or not, you must check its consistency and smell it. If the ointment is sticky and smells good, then it’s safe to use; on the other hand, if it appears dry or separated from its tube, then it likely won’t work as well and should be discarded. Additionally, consider what type of wound you are treating and how old the ointment is before making a final determination.


Neosporin is a triple-antibiotic ointment that can help prevent skin infections in minor cuts and scrapes. It may also speed up wound healing while providing less pain. However, only apply it topically on small areas of skin — never by mouth!

Applying antibiotics to large areas of skin can be both hazardous and could promote antibiotic-resistant bacteria growth. A safer option would be using Vaseline or another lubricant with antibacterial properties, such as petroleum jelly.

To properly dispose of a tube of Neosporin, throw it away in the garbage. However, for best results, mix it with coffee grinds or cat litter before throwing into your regular trash can. Alternatively, if the tube has expired, take it to a TerraCycle drop-off point and have it recycled into other products like clothing or furniture.

Neosporin may not be the only thing you need to help you say goodbye to friends and family at your next get-together, but it remains the most popular topical ointment available today. In fact, it’s the most widely used antibiotic ointment, making it an essential part of every household medicine cabinet. While the cost may seem high initially, its numerous advantages make it worth investing in. According to ClinicSpots — an online dermatology portal — it will prevent infections caused by microorganisms while making your skin look as good as new again!


Neosporin is a triple antibiotic ointment containing neomycin, polymyxin B and bacitracin that is applied directly onto the skin in order to prevent infection and promote healing from wounds. According to its package label, it should be applied at least 3 times daily on affected areas for maximum effectiveness.

If you detect that a tube of neosporin is expired, discard it and replace with a fresh one. Signs such as an unpleasant odor, discolored coloration or other indications suggest that this medication has gone bad should be enough for now.

Expired medications can cause skin irritation around wounds, so it’s best to use fresh tubes whenever possible. You may also send your expired neosporin bottles to TerraCycle, a company which upcycles used packaging and uses it for other uses.

Consumer Reports recommends that you store neosporin in a cool, dry place away from sunlight or heat sources to extend its shelf life. Doing this will help guarantee that your medication remains safe and effective for an extended period of time.

Many people store their first aid kits in bathroom medicine cabinets. Unfortunately, this can be a costly mistake as high humidity in these bathrooms drastically reduces the shelf-life of all medical items – including neosporin.

Therefore, it is essential to store all medical consumables in a cool and dry location in order to extend their shelf life. With this method, you can expect your neosporin product to remain intact up to one year after its expiration date.

As with many medical products, neosporin’s active ingredient degrades over time. To guarantee your neosporin remains potent, all pharmaceutical companies must follow stringent labeling regulations.

These stringent standards require the active ingredient to meet a certain range of potency, which is unique for each product. To guarantee they meet these requirements, these products undergo testing in controlled environments.

According to Consumer Reports, the manufacturer must also determine an appropriate expiration date for their product based on testing results and statistics. This date serves as a guideline that ensures the medication remains safe and effective for as long as possible.
