The smallest thing our body's immune system reacts to?

In summary, tolerance to benzodiazepines develops quickly and the efficacy of the medication decreases over time if taken on a regular basis.

Slightly different question, if we start taking a small constant daily dosage of medicine that quickly reaches some roughly constant percentage in the blood-stream does the body have mechanisms that over a period of days can reduce the percentage of that medicine in the blood-stream even if we continue taking the medicine at a constant daily rate? I was wondering if the immune system attacks medicine?

Thanks for any help!

For starters define "medicine". That is a highly ambiguous term that could mean anything from iron supplements to proteins to live cultures.

Was thinking in particular of the drug Ativan,

What happens is that you build a "tolerance" to the medication whereby it's efficacy decreases over steady (tonic) use. What is tolerance? Well, for psychoactive drugs it's typically downregulation of the relevant receptor(s). I don't think the problem is the immune system attacking the chemical.

From: https://en.wikipedia.org/wiki/Benzodiazepine_dependence

"Tolerance develops rapidly to the sleep-inducing effects of benzodiazepine. The anticonvulsant and muscle-relaxant effects last for a few weeks before tolerance develops in most individuals. Tolerance results in a desensitization of GABA receptors and an increased sensitization of the excitatory neurotransmitter system, glutamate such as NMDAglutamate receptors. These changes occur as a result of the body trying to overcome the drug's effects. Other changes that occur are the reduction of the number of GABA receptors (downregulation) as well as possibly long-term changes in gene transcription coding of brain cells."

My guess is that you got your hands on some benzodiazepines (e.g., Ativan) somehow whether from a friend or legitimate prescription and they're starting to not work as well as they did a couple weeks ago. It's not likely to get any better. So my advice to you (in the spirit of Evo) is to seek professional medical attention for perhaps an alternative solution.

If that doesn't work, I may have a buddy that can help you out :wink: (just kidding).

It is all legally prescribed for a loved one. It was the first drug in 7 weeks that had any effect to reduce some serious anxiety. Started to work this past Friday, worked great Saturday, not as much Sunday, Monday Tuesday. none of this was explained.

Bottom line is she is still in a much better place then last Friday morning, Hell.

Thank you for the help!

Tell your friend to talk to her doctor about it, we can't advise her here.
 

1. What is the smallest thing that our body's immune system reacts to?

The smallest thing that our body's immune system reacts to is a molecule, specifically a pathogen-associated molecular pattern (PAMP) or a damage-associated molecular pattern (DAMP). These are small substances that are recognized by our immune cells as foreign or harmful, triggering an immune response.

2. How does our immune system detect such small molecules?

Our immune system has specialized cells, known as antigen-presenting cells, which are responsible for detecting and presenting small molecules to other immune cells. These cells have receptors on their surface that can recognize specific PAMPs or DAMPs, triggering a response.

3. Can our immune system react to molecules that are too small to see?

Yes, our immune system can react to molecules that are too small to see with the naked eye. This is because our immune system is highly specialized and can detect even the smallest foreign or harmful substances that enter our body.

4. Are there any molecules that are too small for our immune system to react to?

No, there are no molecules that are too small for our immune system to react to. However, some molecules may be too small for our immune system to detect on their own. In these cases, they may need to bind to other larger molecules or be presented by antigen-presenting cells in order to trigger an immune response.

5. What happens if our immune system does not react to small foreign molecules?

If our immune system does not react to small foreign molecules, it may leave our body vulnerable to infection or illness. This can happen if our immune system is compromised or weakened, making it difficult for our body to effectively fight off foreign invaders.
