Is Cipro safe..?

I was prescribed 500mg Ciprofloxacin, one time daily, for three days, for a UTI. I am a 17 year old female with b12 anemia.
I took the first dose 6 and a half hours ago, assuming it was safe, as no serious reactions were listed on the info that came with the prescription. Then I Wiki’d / Googled it, and found many terrible reports of damage done by it.
Now I’m actually quite afraid.
Has anyone had no symptoms on Cipro? Severe symptoms?
Is it likely for it to cause damage with just one 500mg dose?
I’m already having side effects– joint pain and stiffness, headache, stiff neck.
Anxiety over this is setting in, so I will be very grateful to whoever can answer me or share a personal experience.

ALL drugs have potential side effects. In medicine, we always weigh the risk of a drug against its potential benefits.

You have to look at the risk of your UTI – there’s the discomfort of feeling like you have to pee every 5 minutes, and the real risk of the infection going up the urinary system to your kidneys and causing long-term damage there.

The risk of the Cipro is small compared to the risk of losing your kidneys.

If you have a reaction after taking the medication, call the doctor who prescribed the drug. Sometimes there’s an easy fix (nausea – take drug with meals); sometimes, it’s the sign of something more serious.

Be aware that for every person who posted a horror story on the Internet, there are literally millions of people who took the drug, cured the infection, and lived happily ever after.
