Can short term use of cipro, (ciprofloxacin) as a teenager, cause symptoms later in life? as adult, i have gastrointestinal issues, anxiety. possible connection?

Ciprofloxacin: use is not likely to cause long term health problems. If you aren't allergic to it - it is a commonly used antibiotic. I would be doubtful that past short-term use of cipro (ciprofloxacin) led to anxiety in the future. Would anticipate that any gastro-intestinal side effects would have resolved. Take care.

No: While the antibiotic prescribed as a youth very difficult to tolerate and can have long-term side effects, they're not permanent, don't have a decades long latency and are not likely to involve GI system or bring on anxiety. The antibiotic you list as recent (now?) also has several unpleasant side effects that include nausea and diarrhea - so that's more suspect. Have an exam, consider CBT. Best!

Which symptoms??: I'm not sure which "symptoms" you are referring to here. Cipro (ciprofloxacin) is an antibiotic and in general if you are not allergic should not "cause" any problems. There have been some studies suggesting tendon problems in lambs that aren't mature with this class of antibiotics, so for a long time we didn't use any of these antibiotics in kids. While some of them are still suspect, Cipro (ciprofloxacin) is not and is OK.
