Could Botox have affected my kidneys?

The doses used for cosmetic Botox such as you had are too low to have any effect outside of the immediate treatment area. 

It is unlikely Botox had any effect on your kidneys. It is applied locally into the muscle and cannot spread from there.

Thank you for your question.  Botox cosmetic would have no effect on your kidneys.  Best of luck.

Thank you for your question.Botox is injected into a specific muscle and does not spread. It has nothing to do with the recent findings withbyour kidneys.

Botox shouldn't negatively impact your kidneys, because it is injected locally and doesn't spread. I recommend you follow up with your Doctor for a formal evaluation. Best, Dr. Emer

The botox treatment is coincidental.  I recommend having your tests repeated and if they are still abnormal, your physicians will need to decide on an appropriate assessment.

Thank you for your question. Botox/Disport cannot affect your kidney because of localized effect without systemic circulation involvement. 

Thank you for your question. No, Botox cannot affect your kidneys because it has almost no systemic absorption. I recommend contacting your injector if you have any other concerns. Best of Luck!

As noted below the dosage for cosmetic botox is quite low and complications are "local" near the area injected. It is doubtful that it has affected your kidneys.

Thank you for your question. I am really sorry to hear that your eGFR has decreased. As for your question, Botox cosmetic injections do not affect the kidneys filtration rate. Botox stays where it is injected into the muscle. Wishing you all the best,
