Can diphenhydramine have a negative effect on the human body?

Hello, I’m 32 years old and I’ve been struggling with motion sickness since I was a child, so I tried to avoid long and tiring journeys for me. Now, however, my husband came up with an idea to visit Europe and go on a car trip with the children. Realizes that I have problems with motion sickness, but he believes that the stops and properly selected medications will help me and that the whole family will have a great trip.

I admit that I am a bit worried about what it will be like and I have already started reading what drugs are best for motion sickness. I noticed that the majority of it is diphenhydramine and it immediately lit up a red light – what exactly is diphenhydramine and how does it affect my health? I have no idea how many medications I will have to take on this trip, and a little bit, I suppose. Therefore, I am very curious about the side effects of diphenhydramine?

Before a longer trip, we have to make smaller ones so that I can check how I will feel at all. If so, I told my husband that I would not go with them, but I would like to see a little bit of the world. This is not what worries me composition of drugs for motion sickness. So I am asking for reliable information about the side effects of diphenhydramine? Thank you very much. Regards.

The doctor explains the effect of diphenhydramine on the human body

Madam, I am diphenhydramine XNUMXst generation antihistamine drug with antiallergic effect. Compared to second-generation drugs, it additionally has a sedative effect, i.e. a sedative and hypnotic effect. Diphenhydramine reduces allergic symptoms that result from the action of histamine, such as itching, conjunctival redness, tearing, pain and swelling. In the case of side effects, they are classified according to the form of the drug, i.e. whether it is oral, eye drops or nasal.

In the case of the oral form, nausea with vomiting, abdominal pain, dizziness, somnolence are observed, in rare cases renal and hepatic failure. When it comes to nasal drops, a paradoxical reaction consisting in the intensification of local changes may occur. Additionally, there may be heart rhythm disturbances, anxiety, excessive sweating as well as headaches and dizziness.

Eye drops may experience itching and pain in the eyes, conjunctival redness and visual disturbances. Increased blood pressure, headaches and dizziness are very rarely observed. Please remember that oral preparations may impair the ability to drive vehicles.

I would also like to mention the possibility of an overdose of the drug, which may result in excessive sleepiness, slow heart rate, drop in blood pressure, nausea and dry mouth. Diphenhydramine, like any other drug, may have many side effects, although it is considered a safe preparation.
