    erythromycin 500mg QDS for 15 days.
  • Control blood pressure to normal pre-pregnant levels.
  • Ensure diabetes is controlled.
  • For cases of recurrent urinary tract infections, order repeated urine cultures and appropriate chemotherapy.
  • For brucellosis positive cases, give doxycycline 500mg QDS for 3 weeks + streptomycin 1g IM daily for 3 weeks. If pregnant, substitute cotrimoxazole for doxycycline.
  • Offer cervical cerclage in next pregnancy in cases of cervical incompetence.
  • For cases with poor luteal function, give a progestin early in pregnancy, e.g., hydroxyprogesterone 500mg weekly until gestational age is 14 weeks. Then continue with oral gestanon 5mg TDS up to the 6th month.
