it's highly unlikely that botulinum toxin (botox is one common brand) could cause a transient ischemic attack (tia). you don't say why you had injections of botulinum toxin (while people associate botox with cosmetic treatments in truth there are many therapeutic uses for the medication) but it's likely the tias were coincidental to your botulinum toxin injections. tias occur when blood flow to an area of the brain is temporarily blocked (usually by a blood clot) in one of the arteries of the brain. botulinum toxin is a muscle relaxant drug. it isn't injected into the blood stream and has no relationship to clot formation. botulinum toxin is injected into muscles for various reasons -- to smooth wrinkles around the eyes (cosmetic) or to help reduce spasms of the pectoral muscle in breast reconstruction after mastectomy (therapeutic) to name just two examples. if you have any concerns about whether or not botulinum toxin could have been involved in your tia you should talk to the healthcare provider who performed the botox injections. wishing you well!
can botox cause a tia. i've had two episodes of tia and each time i'd had botox injections. i also have two brain aneurysms. the only other factor i have for tia i'd high chlorestorol and it is under control with meds. these episodes were three years apart.
