4 Contraindications

Lo Loestrin Fe is contraindicated in females who are known to have or develop the following conditions:

5 Warnings and Precautions

5.2 Malignant Neoplasms

Additions underlined

Breast Cancer

Lo Loestrin Fe is contraindicated in females who currently have or have had breast

cancer because breast cancer may be hormonally sensitive [see Contraindications (4)].

Epidemiology studies have not found a consistent association between use of combined oral contraceptives (COCs) and breast cancer risk. Studies do not show an association between ever (current or past) use of COCs and risk of breast cancer. However, some studies report a small increase in the risk of breast cancer among current or recent

users (<6 months since last use) and current users with longer duration of COC use [see Adverse Reactions (6.2)].

6 Adverse Reactions

6.2 Postmarketing Experience

 

New subsection added

Five studies that compared breast cancer risk between ever-users (current or past use) of COCs and never-users of COCs reported no association between ever use of COCs and breast cancer risk, with effect estimates ranging from 0.90 - 1.12 (Figure 1).

Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 1). One of these studies reported no association between breast cancer risk and COC use. The other two

studies found an increased relative risk of 1.19 - 1.33 with current or recent use. Both of these studies found an increased risk of breast cancer with current use of longer

duration, with relative risks ranging from 1.03 with less than one year of COC use to approximately 1.4 with more than 8-10 years of COC use.

PATIENT INFORMATION

Additions underlined

Do birth control pills cause cancer?

It is not known if hormonal birth control pills cause breast cancer. Some studies, but not all, suggest that there could be a slight increase in the risk of breast cancer among current users with longer duration of use.

If you have breast cancer now, or have had it in the past, do not use hormonal birth control because some breast cancers are sensitive to hormones.

8 Use in Specific Populations

8.1 Pregnancy

(Additions and/or revisions underlined)

Risk Summary

There is no use for contraception in pregnancy; therefore, Lo Loestrin Fe should be

discontinued during pregnancy. Epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies and limb- reduction defects) following exposure to combined hormonal contraceptives (CHCs) before conception or during early pregnancy.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4 percent and 15 to 20 percent, respectively.

Data

Human Data

Epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to CHCs before conception or during early pregnancy.

8.2 Lactation

(Additions and/or revisions underlined)

Risk Summary

Contraceptive hormones and/or metabolites are present in human milk. CHCs can reduce milk production in breastfeeding females. This reduction can occur at any time but is less likely to occur once breastfeeding is well-established. When possible, advise the nursing female to use other methods of contraception until she discontinues breastfeeding. [See also Dosage and Administration (2.2).] The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Lo Loestrin Fe and any potential adverse effects on the breastfed child from Lo Loestrin Fe or from the underlying maternal condition.

4 Contraindications

(Additions and/or revisions are underlined)

Do not prescribe Lo Loestrin Fe to women who are known to have the following conditions:

  • Use of Hepatitis C drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to the potential for ALT elevations

5 Warnings and Precautions

5.4 Risk of Liver Enzyme Elevations with Concomitant Hepatitis C Treatment

(Newly added subsection)

During clinical trials with the Hepatitis C combination drug regimen that contains ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, ALT elevations greater than 5 times the upper limit of normal (ULN), including some cases greater than 20 times the ULN, were significantly more frequent in women using ethinyl estradiol-containing medications, such as COCs. Discontinue Lo Loestrin Fe prior to starting therapy with the combination drug regimen ombitasvir/paritaprevir/ritonavir, with or without dasabuvir. Lo Loestrin Fe can be restarted approximately 2 weeks following completion of treatment with the Hepatitis C combination drug regimen.

7 Drug Interactions

7.3 Concomitant Use with HCV Combination Therapy – Liver Enzyme Elevation

(Newly added subsection)

Do not co-administer Lo Loestrin Fe with HCV drug combinations containing ombitasvir/ paritaprevir/ritonavir, with or without dasabuvir, due to potential for ALT elevations.

Patient Information

(Additions and/or revisions are underlined)

Who should not take Lo Loestrin Fe?

  • Take any Hepatitis C drug combination containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir. This may increase levels of the liver enzyme “alanine aminotransferase” (ALT) in the blood.

What are the most serious risks of taking Lo Loestrin Fe?

A few women who take birth control pills may get:

  • Take any Hepatitis C drug combination containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir. This may increase levels of the liver enzyme “alanine aminotransferase” (ALT) in the blood.
