I was prescribed a course of doxycycline & am just curious - should i try to include some probiotics in my diet?

Yes if okay with M.D: Probiotics can help to counter the GI side effects of most antibiotics. Probiotics can be taken as individual tablets or as contained in drinks and yogurt. The studies in this area have shown some promising results, but more studies are needed. Your physician can further advise you. I hope that this helps. If you have an underlying immunodeficiency, please check with your doctor.

What were you: Probiotics will not hurt, but are not necessary.

Vaginitis is a 5-10%: Issue in women, so probiotics would be helpful, but would have to be in high enough dose. If you are not experiencing vaginitis, then you may not need it immediately. In general, any broad spectrum abx can do this. However, probiotics can be dietary, meaning not yogurt, but also fermented vegetables, like sauerkraut, kimchee, and pickles. So, enjoy a healthy meal too!
