Before starting the birth control pill, it's a good idea to review Loestrin warnings and precautions with your healthcare provider. For example, you should be aware that Loestrin may have an effect on blood pressure and blood sugar, and it may also interact with certain drugs. Loestrin warnings and precautions also apply to women who are pregnant or breastfeeding.
Liver disease, such as liver failure, cirrhosis, hepatitis, or liver tumors
Cancer (or if you have had cancer in the past)
Undiagnosed vaginal bleeding.
Also, let your healthcare provider know if you are:
Over 35 years old
A smoker
Pregnant or thinking of becoming pregnant
Breastfeeding.
You should also be sure to tell your healthcare provider about all other medicines you are taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
(Loestrin is equivalent to Junel™ and Microgestin®birth control pills. The information in this article also applies to both of these medications.)
