Why Am I Getting Peripheral Tingling and Numbness from Rosacea Treatments?

Numbness and tingling of the hands and feet may be a result of a neuropathy, a malfunction of nerves.  Neuropathy can have many causes and needs to be evaluated.  Some medications are known to cause neuropathy, but usually the infgested forms of these medications.  Your symptoms need to be evaluated by a neurologist to rule out any other potential causes of the numbness and tingling.

Doxycycline can potentially cause dizziness, but symptoms like numbness and tingling in your hands and feet from topical medications sounds quite unusual.  There are a few medical reports of clindamycin being absorbed systemically and causing colitis, but it is exceedingly rare. 

Oral forms of erythromycin and metronidazole have been reported to be associated with a neuropathy, but not topical.

Finacea is not associated with any neurologic symptoms.

To answer your question, if you are a candidate for laser treatment, that may be an option for your rosacea, since it does not involve any medications.  Also, if you are not allergic to sulfur/sulfacetimide combination topical preparations, these also do well with rosacea.

Most importantly, please see a neurologist for an evaluation.
