I wouldn't.

I would just take the medication, make sure you are clear, and not have sex until you are all cleared up. If you do that, you should be fine.

Because infections impact men differently (are more external than internal, more located in the urinary tract than reproductive tract) I wouldn't share medication unless he saw a doc and the doc suggested it.

I've had recurring gardnerella infections (Bacterial Vaginitis) for two years and finally found a doctor who cured me. She gave me and my partner 1 mega-dose of flagyl (we both took 4-500 mg pills at one time. She told me this 2 gram flagyll treatment is the newest protocol for treating BV gardnerella and it worked. The smell is gone and the pills had no side effects on either of us. One caveat--you can't drink alcohol for 24 hours after taking flagyll or you'll get really sick. Although treating the male is considered "controversial" the fact is that the bacteria will colonize in the urethra of the man. So you need to knock it out of him too or he'll keep reinfecting you.
