Home Treatment  
Discontinue the birth control pills. The poisoning is unlikely to be life threatening, but if an overdose has occurred call Poison Control for further instructions.

Before Calling Emergency  
Determine the following information:

  • Patient’s age, weight, and condition  
  • The name of the product (ingredients and strengths if known)  
  • When it was swallowed  
  • The amount swallowed  
  • If the medication was prescribed for the patient

Poison Control, or a local emergency number  
Call Poison Control or your local emergency number - they will instruct you if it is necessary to take the patient to the hospital. See Poison Control Centers for telephone numbers and addresses. Take the container with you to the emergency room.

What to expect at the emergency room  

Some or all of the following procedures may be performed:

  • Inducing vomiting  
  • Treating the symptoms

Note: A trip to the emergency room will probably not be necessary.

Expectations (prognosis)
