Does taking Benadryl affect longevity of Botox results?

Taking Benadryl will not impact your Botox treatment or longevity. Botox wears off gradually over three to four months on average. I've included a video about neuromodulators that I hope you find helpful.

Thank you for your question.  Antihistamines would not interact with the longevity of Botox.  Best regards

Benadryl antihistamine does not affect the effectiveness or duration of Botox. There should be no concern that you will have a negative consequence having had Botox should you take Benadryl in the evening to help you sleep.

I'm not aware of any relationship between benadryl and Botox - the medications work on different systems and are metabolized with different physiologic pathways.

You can continue taking benadry since it has no effect on your botox results or its longevity.
