These interindividual differences in the elimination of this medicine are known to be a result of various factors.
These mainly consist of a frequency of ingestion, person’s age, dosage, hepatic function and co-administration of other drugs.
It is these factors that are needed to be considered when contemplating the amount of time Benadryl stays in your body after you stop consuming it.

Based on this information, it can be concluded that it around 3.1 days for the complete elimination of diphenhydramine from the body systems of the elderly individuals.
The statistic’s say that around 2.11 days are required by the young adults for the complete elimination of Benadryl and only 1.24 days by kids.
2. Hepatic Function
The clinical study says that the content of diphenhydramine present in Benadryl is metabolized by certain enzymes present in our liver.
Thus, the elimination of Benadryl contents is affected because of the hepatic impairment. If the liver is damaged in any way, then the lifespan of Benadryl in the human body is highly affected.
It can take around 4 to 6 for the complete elimination of the entire content of Benadryl from the human body if you are suffering from or having the severe hepatic impairment.
Research proves that the increased time of complete elimination is longer among cirrhotic patients. This is mainly because of increase in the bilirubin content.
In case of adults having a normal hepatic functioning, complete elimination of Benadryl occurs in just 2 days or so.
3. Dosage (Low vs. High)
This is one of the major factors to be considered while checking out how long Benadryl will stay in your body. The dosage of Benadryl is given as per the individual’s age.
It is as follows:

- Adults and old people – 25 mg to 50 mg
Thus, it can be easily noted that higher the amount of dose; greater is the time duration for which the medication will reside inside your body. However, there are other factors as well which influence the time span.
4. Frequency (Single Vs. Multi-Dose)
How often do you consume Benadryl?
The answer to this question is surely going to affect the time duration for which the drug resides inside the human body. It is logical to say that a person who takes a single dose of the medication per day is bound to eliminate the drug at a faster rate.
On the contrary, the person taking it multiple times a day will take more time to eliminate it. This is primarily due to the logic that a user taking a single dose user is likely to have less amount of accumulated Benadryl in his body.
5. Co-Administration Of Drugs (CYP2D6)
If you’re consuming other drugs along with Benadryl, then it is possible that there might be an increase or decrease in the time required for its complete elimination.
Clinically, it is proven that the enzyme Cytochrome P450(CYP2D6) affects the diphenhydramine which is the active ingredient in Benadryl.
Thus, taking into consideration the other medications the person is ingesting becomes important too.

It is a general scenario that an individual with a large count of BMR tends to burn more energy as well as fat. This greatly affects the rate at which the drugs are eliminated from the human body
- Renal function: Medically it is proven that people suffering from issues with the liver are having a low dissemination rate of drugs.
- Urinary pH: People had a high urinary pH are likely to require more time for complete elimination of Benadryl. High pH leads to increased acidity, which in turn affects the body metabolism.
