The doctor had prescribed me 100 mg doxycycline twice daily for 14 days. On 9th day of medication, I had itching in different parts of my body. Then I consulted the doctor but he asked me to continue the doxycycline and complete the course. To control itching he gave me antihistaminic drug for the remaining medication period. Even after completing the course of medicine I had little bit itching for one more week.
