Specific Kurvelo Precautions and Warnings

Some warnings and precautions to be aware of prior to taking this medication include the following:
  • When used properly, Kurvelo is quite effective at preventing pregnancy. However, it becomes much less effective if you take it incorrectly. Make sure you understand exactly how to take Kurvelo, including how and when to start it and what to do if you miss pills. If you cannot remember to take Kurvelo regularly, birth control pills may not be the best option for you.
  • Estrogen-containing contraceptives, including Kurvelo, increase the risk of life-threatening problems, such as heart attacks, strokes, and blood clots. The risk is quite small for healthy, young, nonsmoking women. Make sure to tell your healthcare provider if you have ever had a blood clot, stroke, heart attack, or chest pain.
Smoking cigarettes significantly increases the risk of these serious Kurvelo side effects. This risk is particularly high for smokers over the age of 35.
  • Kurvelo may react with a number of different medications (see Drug Interactions With Kurvelo for more information). Many of these interactions are severe enough to lead to unintentional pregnancy.
  • Kurvelo does not protect against HIV, AIDS, or other sexually transmitted diseases (STDs). In many cases, it is advisable to use condoms in addition to Kurvelo.
  • Oral contraceptives increase the risk of benign (noncancerous) liver tumors. Very rarely, these tumors can rupture and cause serious problems.
  • Hormonal contraceptives, such as Kurvelo, can make gallbladder disease worse. If you have had a problem with your gallbladder, Kurvelo may not be the best contraceptive method for you.
  • Kurvelo may increase blood sugar levels, particularly in women with diabetes. Your healthcare provider may need to monitor you more closely. Let him or her know if you have any sudden vision changes, as this may be a sign of a blood clot in the eyes, which is a possible side effect of Kurvelo and other hormonal contraceptives.
  • Kurvelo can change your menstrual bleeding patterns. Some women have breakthrough bleeding (bleeding between periods), while others may not have a period at all. It is normal to have shorter and lighter periods while using Kurvelo. If you notice any unusual changes in your bleeding patterns, let your healthcare provider know. If you miss a period, you should make sure you are not pregnant.
  • In some cases, hormonal contraceptives can make depression worse. Let your healthcare provider know if you develop new or worsening depression symptoms.
  • Hormonal contraceptives, including Kurvelo, can occasionally cause eye changes that make it more difficult to wear contact lenses.
  • Kurvelo is a pregnancy Category X medication. This means it should not be used during pregnancy (see Nordette and Pregnancy).
  • Contraceptive hormones, such as the ones in Kurvelo, pass through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking the pill (see Nordette and Breastfeeding). Combined hormonal contraceptives, including Kurvelo, are usually not recommended for breastfeeding women.
