"💊 Don't let the antihistamine bite your brain! 🧠❌

.

Anyone who likes to take yellow pills or sleeping pills often must listen! Medical research has warned that using these four old antihistamines for a long time in a row risks more 'dementia' and 'Alzheimer's' than normal people!

.

Quick check in your medicine cabinet, which one do you have?

1. Chlorpheniramine

2. Diphenhydramine

3. Hydroxyzine

4. Dimension hydrinate

Some medical data suggest that the use of "older antihistamines" (first-generation antihistamines) such as Chlorpheniramine, Diphenhydramine, Hydroxyzine, Dimenhydrinate for a longer period of time may be associated with a greater risk of dementia or dementia (dementia / Alzheimer's) than is the continued use of these drugs, especially in the elderly, but not the conclusions that certainly prove the cause in all cases - most research is observational, and more clinical studies are also needed to confirm the direct cause of these drugs to actually dementia.

🧠 Why are these drugs being concerned?

✔️ First-generation antihistamines pass easily into the brain and have anticholinergic effects.

- which means inhibiting the major acetylcholine agents for memory and thought functions.

✔️ Some studies have found that cumulative doses are associated with the risk of dementia and Alzheimer's disease in elderly adults.

📊 what the research found.

📈 The risk increases with consumption.

• People who have been exposed to first-generation antihistamines for an extended period of time and high cumulative doses are more likely to be at risk of dementia on a dose-response basis or at increased risk when repeated doses are taken for several consecutive years.

📉 is not conclusive evidence of a direct cause.

• Most studies are also observational - correlated, but not all "direct Alzheimer's disease-causing drugs" can be told.

📌. Drugs that are often mentioned.

➡️ Chlorpheniramine - reported to have anticholinergic effects and is one of the drugs to watch out for in long-term use.

➡️ Diphenhydramine (Benadryl) - The most talked about example of association with memory and brain function.

➡️ Hydroxyzine - is an early antihistamine, but some sources say the anticholinergic activity may be quite different in each substance.

➡️ Dimenhydrinate - Often used to fix motion sickness / seasickness, and also in the first generation of antihistamine.

🤔 So should I worry?

🔹 Yes - Be careful if you take these drugs continuously for a long time, especially in the elderly or other health risk factors.

🔹 Don't panic - occasional use to relieve allergies is no big deal, and many are not at much increased risk of occasional use.

🔹 safer alternatives - newer (second-generation) antihistamines such as loratadine, cetirizine, fexofenadine that are less likely to enter the brain and have lower anticholinergic effects than older drugs.

👉 Hint: If you take antihistamines frequently or for more than several weeks / months continuously, talk to your doctor or pharmacist to check your drug options and overall risk.

1. Epidemiological study in allergic rooge patients

The use of first-generation antihistamines (FGAs) showed that the more cumulative the dose, the greater the risk of dementia compared to non-drug people, and the higher the risk of new-generation drugs (SGAs).

👉 reported in The Journal of Allergy and Clinical Immunology: In Practice (2024).

2.Research from JAMA Internal Medicine 2015

It was found that prolonged use of anticholinergic drugs (including first-generation antihistamines such as chlorpheniramine and diphenhydramine) was associated with a greater risk of dementia and Alzheimer's than unused people.

3. Conclusion from Healthline

It explains that diphenhydramine (such as Benadryl) belongs to the anticholinergic group, and several studies have found a link between the use of this group of drugs and the risk of amnesia in the elderly.

4. Summary of the article on the risk of older antihistamine drugs

Mention that first-generation antihistamines such as diphenhydramine, hydroxyzine, chlorpheniramine have anticholinergic effects, which is linked to the risk of dementia, with the risk being greater according to the cumulative dose of the drug.

5.General information on antihistamines

According to the H1 antagonist, the use of anticholinergic drugs (including first-generation antihistamines) is associated with a risk of cognitive impairment and dementia in the elderly.

📌 Important note:

🔹 Most research is also observational - showing a relationship, not proving that "drugs are the direct cause" of Alzheimer's in all cases.

🔹 The risk is often greater when used consecutively for prolonged periods and accumulates large amounts, especially in the elderly.

🔹 for occasional or brief use to reduce allergies is definitely not the cause of dementia in common people.

📌 Important notes from the source.

✔️ Several studies that discussed the use of anticholinergic drugs (including some of the first-generation antihistamines) found an association with the risk of dementia and Alzheimer's disease in a dose-response analysis - the more cumulative the use, the greater the risk, especially when used in the long-term and among the elderly.

✔️ Evidence in many cases comes from observational studies showing a correlation - not all causal causes (direct causes) cannot be confirmed - so they must be considered in combination with other factors and should not be stopped without consultation.
