In summary, the conversation discusses the use of topical ointments for skin problems and the potential risks of them entering the bloodstream. It is advised to strictly avoid direct contact with open wounds or mucous membranes. Medical advice should be sought if there are concerns, and it is important to read the instructions and warnings on ointment packaging. In terms of first aid, sterile water is recommended for irrigating wounds and covering with sterile dressings, while burns should not be treated with ointments. Antiseptic wipes can be used for minor injuries. Additional resources on wound care can be found through Mayo Clinic and the CDC.

TL;DR Summary
Can ointments cross the skin barrier.
This is probably the wrong forum to ask this question, but here goes: in the case of skin problems, boils, even open wounds possibly (?) can various ointments - antiseptic creams, for instance - get into the bloodstream? And if so, could this cause additional health problems? Thanks in advance.

At least parts of it, for otherwise it would be senseless to use them. However, in any case direct contact with open wounds, cuts or scratches, or even with conjunctiva or mucosa should usually strictly be avoided!

Even if they might not be a serious danger - and you cannot know, e.g. in the eyes, it is at least painful and an obstacle for the healing process.

We cannot give additional medical advice, since this would be irresponsible. All we can say are those common information. If in doubt, ask a doctor or a pharmacist, and study the package insert.

Thread closed.

I'll add a couple links about first aid, in case that helps the OP and others.

For prehospital EMS, we use sterile water to irrigate wounds and cover with sterile dressings for transport to the Emergency Department (ED) at the hospital. For Wilderness Medicine, we irrigate with water and treat with triple antibiotic ointment (or Bacitracin if the Patient has sulfur allergies), and cover with a sterile dressing. Burns generally do not get any ointments, since they need to be cleaned at the ED. Antiseptic wipes can be used for simple lacerations and abrasions, along with irrigation.

FAQ: Ointments and the bloodstream query

1. What are ointments and how do they work?

Ointments are semi-solid preparations that are applied topically to the skin. They are made up of a base, such as petroleum jelly or lanolin, and may also contain active ingredients such as medications or herbs. Ointments work by forming a protective layer over the skin, which helps to retain moisture and protect the skin from irritants. They can also deliver medications directly to the affected area.

2. Can ointments enter the bloodstream?

Yes, some ointments can enter the bloodstream, but the amount that actually enters the bloodstream is minimal. This is because the skin acts as a barrier and only allows small molecules to pass through. Ointments with active ingredients that are designed to be absorbed into the bloodstream will have specific instructions for application, such as applying to a thin and highly vascularized area of the skin.

3. Are there any risks associated with ointments entering the bloodstream?

There can be potential risks associated with ointments entering the bloodstream, especially if they contain medications or herbs. These risks can include allergic reactions, drug interactions, and systemic side effects. It is important to always follow the instructions for use and consult with a healthcare professional if you have any concerns.

4. How long does it take for an ointment to enter the bloodstream?

The time it takes for an ointment to enter the bloodstream can vary depending on the type of ointment and the area of the skin it is applied to. Generally, it can take anywhere from a few minutes to a few hours for an ointment to be absorbed into the bloodstream. This can also be affected by factors such as the thickness of the ointment and the condition of the skin.

5. Are there any alternatives to ointments for delivering medications to the bloodstream?

Yes, there are other methods for delivering medications to the bloodstream, such as oral medications, injections, and transdermal patches. Each method has its own advantages and disadvantages, and the best option will depend on the specific medication and the individual's needs. It is important to consult with a healthcare professional to determine the most appropriate method of medication delivery for your specific situation.
