Question: I just finished a 10-day course of flagyl after testing positive for C Diff. Around day 5 on the drug my symptoms improved, somewhat. Now that I'm finished, I'm still having 1-3 loose stools per day and a GI specialist I spoke with said I could expect this for the next 3-4 weeks. My questions are: 1. can I take an over-the-counter diarrhea aid to help 2. Will the side effects from the flagyl (nausea, dizziness, head/joint ache, fatigue, darkened urine, night sweats) subside soon? 3. Was 10 days enough on the flagyl or should it have been prescribed for 14?

Thank you for the query.

Before the answers for your question let me write some things. As you have been treated with two antibiotics recently, your regular, protective intestinal bacterias has been destroyed and this two antibiotics has left some kind of mess in bacterias cultures. It needs some time for it to get back to the regular state. Without this good bacterias, your intestines does not work property. Until this wont be reversed, you may have symptoms like diarrheas or loose stools.
Answering to your questions:
1. Yes, you can take anti diarrhea medicines (like Loperamide 4mg 3 times a day). You should also add probiotics, have soft diet. Rifaximine therapy might be also very helpful at your case. This is an antibiotic which does not get absorbed, works only inside the intestines and affects only those bad bacterias.
2. Yes, this symptoms should go away in a few days. If not, you should visit your doctor again.
3. Yes, 10 days is enough. No need for longer treatment.

Hope this will help. Feel free to ask further questions.

Thank you, that is very helpful. I don't think my doctor will be willing to prescribe rifaximine as she has told me to wait 7 days to see improvement. I have been taking a probiotic for the past 10 days, specifically Saccharomyces Boulardii which I read is helpful in the treatment of C Diff as well as eating a lot of plain yogurt.

Again, Thank you for your help.

Than just continue probiotic and yogurt. It should work even without Rifaximine.

I had casual sex a month ago and a few days after felt the head of my penis burning as well as the part between testicles and anus (urethra?). Some days I felt a sensation like urine incontinency and sometimes i detect discharge which looks and feels very much like pre-semen, but I have found that that discharge is mostly after having sex or just an erection.

I consulted a general medician first and a uro-whatever doctor afterwards. The latter made tests for chlamydia (blood test), VIH, Sifilis, and another urine test (I already had one taken with the first sympthoms). Everything was negative/ok, just mucin was high both times. Now, the first doctor recommended a treatment of Ciprofloxacine with some red pills that made me pee orage color, both for a week. The second doctor gave me some 7 pills that were a mixture of Tinidazole (250 mg), Azitromicine (500 mg) and Fluconazole (37.5) and instructed me to buy 3 more for a total 5 days. Since I was not able to get that combined pill in local drugstore I bought last two separated and Metronidazole instead of Tinidazole. I finished the treatment. Pain has mainwhile relieved mostly, but I still see the discharge. Any suggestions?

Kindly suggest me what to do.
