My wife has mouth ulcer in upper dome near the upper front teeth. My doctor in India had prescribed her with Doxycycline cap. IP 100 mg, morning ,evening each. This cap. is exhausted, and we have arranged its substitute as Doxycycline Hydrochloride & Lactic acid Bacillus Tablets " DOXIL-100" from India. presently we are in USA on vacations. I wish to know if the substitute medicine will work for the problem. Thanks
