Discussion Overview

The discussion revolves around the potential for various ointments, particularly antiseptic creams, to penetrate the skin barrier and enter the bloodstream in the context of treating skin problems such as boils and open wounds. Participants explore the implications of this possibility for health and safety.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions whether ointments can enter the bloodstream when applied to skin problems, suggesting this could lead to additional health issues.
  • Another participant references "topical/topical use only" warnings found on ointment packaging, implying a limitation on their intended use.
  • A different participant asserts that ointments can cross the skin barrier to some extent, but emphasizes the need to avoid contact with open wounds and sensitive areas like the eyes due to potential complications.
  • There is a caution against providing medical advice, with a recommendation to consult healthcare professionals for specific concerns.
  • One participant shares links to first aid practices, detailing methods for wound care and the use of specific ointments, although this does not directly address the original query about bloodstream absorption.

Areas of Agreement / Disagreement

Participants express differing views on the extent to which ointments can penetrate the skin barrier and the associated risks. There is no consensus on the implications of ointment absorption into the bloodstream.

Contextual Notes

Limitations include the lack of detailed scientific evidence provided in the discussion regarding the absorption of ointments and the specific conditions under which this may occur. The conversation also reflects a reliance on general information rather than definitive medical guidance.

TL;DR
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.
