The concern that has received the most attention is the risk of tendon rupture. Fluoroquinolones, including ciprofloxacin (Cipro) and levofloxacin (Levaquin), are often used to treat urinary infections. These antibiotics have been associated with increased risks of tendon ruptures.
Antibiotic-associated diarrhea can occur when you take antibiotics. These medications can alter the normal bacteria in the G.I. system. In order to decrease your chance of having diarrhea, your doctor can keep the duration of antibiotic treatment as short as possible that still eliminates the infection.
Antibiotics that have been linked to photosensitivity are a concern for anyone who plays outdoor sports or exercises outside. Tetracyclines, fluoroquinolones and sulfa drugs are believed to carry this risk. It is possible that you could develop a serious sunburn on body parts exposed to the sun or have an increased risk of skin cancer if you use these medications. Theoretically you should avoid these antibiotics or use sunscreen and wear fully protective clothing.
By no means does this list of concerns represent medical advice. If you have an infection and require antibiotic treatment, you should ask the doctor about possible complications with those drugs, especially as they pertain to exercise and sports.

Dr. David Geier I had an abscessed tooth and had to get a root canal. I’m on amoxicillin for the next 2 weeks, 500 mg 4 times a day. This is quite an inconvenience because I was just in the middle of my winter training for the track season. I am a long distance runner who runs the mile and 2 mile and generally runs between 40-50 miles per week. I had to take 3 days off of running completely and am nervous how my runs will go on the antibiotics. Any thoughts?
Hi Dr David Geier. I have a throat infection that is starting and the doctor gave me 3 days antibiotics to treat it. I will be taking the first today and the last on thursday. The big problem for me is that I am a boxer and I have the national championships this weekend. I will probably only fight on sunday. I need to train because of my weight class during these days. The trainings are not aggressive in fight week but i'm worried if it will affect my performance in the fight. What do you think? I will stop taking it 3 days before the fight. Right now im not feeling bad but the illness is progressing and i cant take that risk because i trained the whole year for this. I would really appreciate your help. Thank you
Hi Dr I had major nuro opperation cos by sinus which turn into septic and almost hit my brain. Now I am taking penicillin 4 tablets 2 times in a day. Dr I just want to know can I do some basic exercise in the gym . Tq Dr
While at the movies (Sawgrass) later in the day after a 10 mile workout (half marathon training) I urinated bright red blood. I freaked out and went to a urologist. He did some unspeakable-very uncomfortable testing. He then prescribed levaquin (Flouroquinilone), and the donkey forgot to tell me to stop training. The next day 10 minutes into my run at beautiful , Hollywood Beach in Florida, I cramped up big time. Then I read about all the poor souls who had tendons ruptures doing the same thing. All kinds of lawyers were offering their services to the afflicted.
Turns out I had no infection AT ALL. ALL IT WAS.. I DIDN'T DRINK ENOUGH WATER.
Same thing happened ironically to my own doctor. My brother in law, also a doctor (nephrologist) said I over did it...and didn't need all that testing. MORAL OF THE STORY: HYDRATE PROPERLY...BOYS AND GIRLS. Levaquin is a very strong antibiotic with the kick of a mule.

Hi doctor, I was bitten by some insect (maybe a tick) and it caused a bruise similar to this one that occurs in Lyme. My doctor said that if it isn't growing and is disappearing there is no need to take antibiotics, because it's not borellia. And it has dissppeared but I noticed another two barely visible little bruises a couple centimeters below the bite place. I have a little bit of OCD temper so to be sure I convinced my doctor to prescribe antibiotics. I've just started therapy, I feel okay and healthy. I would like to ask if I can train (gym, swimming, aerobics) during the therapy with doxycycline. Obviously I will avoid sun. It would be really helpful if you answer. Thank you in advance and sorry for my broken English :)
Scott Broadbent well said! I haven't ever taken antibiotics for (and I dont eat animals or anything from them) and I still had to sit through 10 mins of antibiotic speal with the GP after getting a tick bite.
If we stopped pumping ABiotics into animals AND ourselves we wouldnt be in this mess.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
