Yes, you can take Tylenol and Benadryl together. Generally, taking both of these medications together is safe and there are no known drug interactions. However, it is important to talk to your doctor before taking any medication, especially if you are taking other medications or have any health concerns.
Tylenol is generally considered a safe medication and is used to treat pain, fever, and headaches. It is usually the first choice when it comes to over-the-counter pain relievers. Benadryl is an antihistamine that is typically used to treat allergies, hay fever, and other types of skin reactions.

Does Benadryl raise blood pressure?
The short answer to the question of whether Benadryl raises blood pressure is that it is unlikely to do so in most people. Benadryl (generic name diphenhydramine) is an antihistamine medication primarily used to treat allergies.
It has been studied and found to cause a slight increase in blood pressure in those taking the medication, though for the most part this increase is considered to be minimal.
In a study published in 1983, researchers found an average, small and clinically insignificant increase in diastolic and systolic blood pressure about an hour after Benadryl was administered in seven volunteers.
However, when looking at other studies, the consensus is that Benadryl does not have a major effect on blood pressure and instead works as an antihistamine to treat allergies.
It is important to note that some research has indicated that those already experiencing high blood pressure should use caution when taking Benadryl, as it could adversely affect blood pressure control.
People with existing hypertension should discuss with their doctor the risks involved when considering taking Benadryl.
In conclusion, the research indicates that for most people, Benadryl does not have a major effect on blood pressure. However, if you have existing hypertension, it would be wise to discuss the potential risks with your doctor before taking Benadryl.
Is it safe to drink alcohol while on Benadryl?
It is not recommended to drink alcohol while taking Benadryl (diphenhydramine). Alcohol can increase the effects and side effects of Benadryl, such as increased drowsiness, sleepiness and feeling faint or lightheaded.

Combining Benadryl and alcohol together can increase the risk of serious side effects such as liver damage, seizures, or an irregular heartbeat, and can cause an increase in the side effects of both substances.
If you must consume alcohol while taking Benadryl, it is important to do so responsibly, drink only in moderation, and talk to your doctor to ensure the safe use of both substances.
Is Benadryl bad for your liver or kidneys?
No, Benadryl (diphenhydramine) is not bad for your liver or kidneys. In fact, Benadryl has not been linked to any long-term damage or complications related to the liver or kidneys. Benadryl is considered generally safe and well tolerated when used as directed.
However, it can cause side effects in some people, particularly in those who take too much. As with any medication, it’s important to talk to your doctor before taking it as this will ensure that it is safe for you, and that it won’t interact with any medications you are currently taking.
You can also ask your doctor if there are any specific concerns about the liver or kidneys when taking the medication.
Can you mix antihistamines and alcohol?
No, you should not mix antihistamines and alcohol. Combining antihistamines with alcohol can significantly increase your risk for negative side-effects and dangerous medical interactions. Antihistamines are drugs used to treat allergies, cold, and other illnesses, and can cause drowsiness, dizziness, and confusion.
When combined with alcohol, these effects can be intensified and increase the risk of accidents and injuries. Additionally, combining antihistamines with alcohol can also weaken the effects of the antihistamine, making it less effective at treating your symptoms.
It is important to always talk to your healthcare provider before taking any drugs, including antihistamines, and even more so when drinking alcohol.
How many Benadryl can I take to sleep?
