Deaths From Antihistamine Overdose

There have been reports of death due to antihistamine toxicity. These include accidental overdoses and intentional misuse.

Death can occur when an overdose causes severe complications such as respiratory distress, cardiac arrest, or seizures. Each persons tolerance to medication can vary. However, toxicity usually occurs when a person ingests three to five times the recommended dosage.

Medical emergency

To avoid life-threatening complications, call 911 or go to the emergency room if you have any symptom of an overdose. You can also call the Poison Control Help Line at 800-222-1222.

Several Factors Impact How Quickly Benadryl Is Metabolized Including: 3

  • Age: Adults over 65 years old and children younger than 12 years old metabolize diphenhydramine more slowly, so lower doses less often are safer.3
  • Liver problems: Since the active ingredient in Benadryl is processed through the liver, anyone with decreased hepatic function will have difficulty safely consuming this drug.
  • Kidney problems: The kidneys help to process toxins by passing them out through the bladder. People who have decreased renal function may have a tough time metabolizing Benadryl. Urinary pH can also impact how the body processes diphenhydramine.
  • Hydration: People who do not drink sufficient water may struggle to eliminate diphenhydramine from their system.
  • Low vs. high dose: Even healthy adults who take more than the recommended dose of Benadryl will experience consequences, such as taking longer to metabolize the drug. Taking the recommended dose of Benadryl for longer than recommended may also lead to tolerance as the drug builds up in the body, and that also might increase the medications elimination time.
  • Other medications: Taking prescription drugs, or other over the counter drugs, along with Benadryl may change how the body metabolizes all the substances together.
  • Body weight/mass: Different body types process different amounts of medication at different rates. This is true for prescription drugs, recreational substances like alcohol, and over the counter drugs like Benadryl.

Your child’s provider may ask if your child has any other medical conditions, such as liver problems or diabetes. The provider may ask you how you gave your child his or her medicine and to describe his or her symptoms. Your child may need tests to help providers learn if his or her condition is serious or life-threatening.

  • Blood tests may be needed to give providers more information about your child’s condition. Your child may need to have blood drawn more than once. If you do not know which medicine your child took, blood tests may be able to tell which medicine is in his or her body. For example, blood tests may be done to check for acetaminophen in your child’s body. Blood tests may be used to check his or her liver.

How Antihistamines Work

Antihistamines block the effects of a substance called histamine in your body.

Histamine is normally released when your body detects something harmful, such as an infection. It causes blood vessels to expand and the skin to swell, which helps protect the body.

But in people with allergies, the body mistakes something harmless such as pollen, animal hair or house dust for a threat and produces histamine. The histamine causes an allergic reaction with unpleasant symptoms including itchy, watering eyes, a running or blocked nose, sneezing and skin rashes.

Antihistamines help stop this happening if you take them before you come into contact with the substance you’re allergic to. Or they can reduce the severity of symptoms if you take them afterwards.

A Small Overdose Of Allergy Medicine

Stop a Deadly Overdose With Naloxone From VA

To most people spring is a pleasant season, but to me the blooming flowers and the smells of blossom mean only one thing allergies.

Ive suffered from allergies for as long as I can remember. Im allergic to a long list of trees and grasses . Everything Im allergic to seems to bloom in late April and early May.

I used to take all kinds of medication for my allergies most of them started to work after a few weeks when allergy season ended. But kidding aside, although they did not cure me, they usually relieved some of the sneezing, coughing, itching, and breathing problems I suffer from during the spring

Diabetes changed things with my allergies. The allergies did not get better but the allergy medicine seems to affect my blood sugar levels in a bad way.

So, I made a decision a few years ago to only take allergy medicine when my allergies are so bad I cant function otherwise. I think I draw the line at 20 sneezes per minute.

I was incredibly happy about getting a metformin prescription, but other than that, I just couldnt stand anything.

In the evening I gave in and went to take my allergy medicine. I took the small pill out of the wrapper and then without much thought, took a second pill. My condition was so bad I figured a double dose wouldnt hurt. It took a while for the medicine to work, if it did at all, but when I went to sleep my symptoms seemed better. As soon as I woke up, I took another pill.

Jessica looked at me and said, You look drugged.
