“I can continue using spermicide for birth control.”
“If I have burning when I urinate, I will contact my physician.”
Number 3 is correct.
Rationale: Spermicides can increase the risk of cystitis and another form of birth control should be used if possible. Voiding before and after intercourse minimizes the risk of bacteria being introduced into the urethra. Loose-fitting cotton underwear helps prevent irritation to the area. Burning upon urination may indicate another infection and should be assessed by the health care provider for diagnosis and treatment.
