Question 1

What is Twirla?

Accepted Answer

Twirla is a transdermal system containing levonorgestrel and ethinyl estradiol, which are forms of progesterone and estrogen. These active ingredients primarily function by inhibiting ovulation, which is the release of an egg from the ovaries. Additionally, the system causes changes in the cervical mucus and uterine lining to further reduce the likelihood of fertilization.

Question 2

What is Twirla used for?

Accepted Answer

Twirla is used to treat contraception .

Question 3

How does Twirla work?

Accepted Answer

Mechanism of Action

Twirla is a transdermal system, commonly known as a patch, that delivers a continuous flow of two hormones: levonorgestrel (a progestin) and ethinyl estradiol (an estrogen). These hormones are absorbed through the skin and enter the bloodstream directly to regulate the reproductive cycle.

The medication prevents pregnancy through several different methods:

Inhibiting Ovulation: The primary function of the hormones is to signal the brain to stop the ovaries from releasing a mature egg each month. If no egg is released, fertilization cannot occur.

Cervical Mucus Changes: The hormones cause the mucus in the cervix to become thicker and stickier. This creates a physical barrier that makes it much harder for sperm to swim into the uterus to reach an egg.

Uterine Lining Alterations: The patch changes the lining of the uterus, making it thinner. This change makes the environment less receptive for a fertilized egg to implant and develop.

Question 4

The active ingredients in Twirla are ethinyl estradiol and levonorgestrel .

Question 5

Headache

Nausea

Application site irritation

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Twirla?

Accepted Answer

Twirla belongs to the combined hormonal contraceptive drug class.

Question 7

What is the dosage of Twirla and how do I take it?

Accepted Answer

How to Use the Patch

Twirla is applied to the skin once a week. Each patch is worn for one week. You should choose a specific day of the week as your Patch Change Day and replace the patch on that same day every week during the first three weeks of your cycle.

Week 1: Apply the first patch.

Week 2: Remove the old patch and apply a new one.

Week 3: Remove the old patch and apply a new one.

Week 4: Remove the patch and do not wear one for this week. This is typically when your period will occur.

Where to Apply

Apply the patch to clean, dry, and intact skin. Suitable areas include the abdomen, buttocks, or the upper torso. Do not apply the patch to the breasts or to skin that is red, irritated, or cut. To help prevent skin irritation, you should rotate the application site each time you apply a new patch by choosing a different spot than the previous one.

Avoid using lotions, oils, powders, or makeup on the area where you plan to place the patch or around a patch that is already in place, as these products may cause the patch to loosen or fall off.

If a Patch Falls Off or is Missed

If the patch becomes loose or falls off, try to reapply it or replace it with a new one immediately. If the patch has been off for an extended period, you may need to start a new cycle and use a backup method of birth control, such as condoms or spermicide, for the first week of the new cycle.

If you forget to change your patch on your scheduled day, apply a new patch as soon as you remember. Depending on how much time has passed since your scheduled change day, you may need to use backup contraception for several days to prevent pregnancy.

Question 8

Is Twirla safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Twirla is a hormonal patch used to prevent pregnancy and should not be used by individuals who are already pregnant. If pregnancy occurs while using the patch, it should be removed and discontinued immediately. Current evidence suggests that the accidental use of hormonal contraceptives during early pregnancy does not significantly increase the risk of birth defects.

Breastfeeding

The use of hormonal contraceptives containing estrogen, such as Twirla, can decrease the quantity and quality of breast milk. Small amounts of the active hormones may also pass into breast milk and could potentially affect a nursing infant. Healthcare providers generally recommend using other forms of birth control until a nursing infant is completely weaned. It is important to discuss the risks and benefits of various contraceptive methods with a clinician while breastfeeding.

Question 9

What forms and strengths does Twirla come in?

Accepted Answer

Dosage Form

Twirla is available as a transdermal system, which is a patch applied to the skin. The patch is round, beige, and consists of three layers designed to deliver medication through the skin and into the bloodstream.

Strengths

This medication is provided in a single strength. It contains a combination of two active ingredients:

Levonorgestrel (a progestin)

Ethinyl estradiol (an estrogen)

The system is designed to release a specific daily dose of these hormones continuously over a period of seven days. Each patch is worn for one week before being replaced.

Question 10

What is the FDA approval status of Twirla?

Accepted Answer

FDA Approval Status

The U.S. Food and Drug Administration (FDA) approved Twirla in February 2020. It is a combined hormonal contraceptive patch containing the active ingredients levonorgestrel and ethinyl estradiol.

Approved Indications

Twirla is indicated for use by women of reproductive potential to prevent pregnancy. Its use is specifically restricted based on the user's body mass index (BMI) due to safety and efficacy concerns identified during clinical trials.

Boxed Warnings

The FDA has required a Boxed Warning for Twirla regarding the following risks:

Cigarette Smoking and Cardiovascular Events: Cigarette smoking increases the risk of serious cardiovascular events from combined hormonal contraceptive use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked. For this reason, Twirla is contraindicated in women over 35 who smoke.

Body Mass Index (BMI) and Thromboembolism: Twirla is contraindicated in women with a BMI of 30 kg/m² or greater. Clinical data showed that women in this BMI category have an increased risk of venous thromboembolism (blood clots) and that the patch is less effective in preventing pregnancy compared to women with a lower BMI.

Limitations of Use

Twirla may have reduced effectiveness in women with a BMI of 25 kg/m² or greater but less than 30 kg/m². Healthcare providers are advised to consider this limitation when prescribing the patch to individuals in this weight range.

Question 11

What should I know about Twirla and birth control?

Accepted Answer

How Twirla Prevents Pregnancy

Twirla works as a combined hormonal contraceptive. It uses two hormones, levonorgestrel and ethinyl estradiol, to prevent pregnancy in three primary ways:

Stopping ovulation: It prevents the ovaries from releasing an egg each month.

Thickening cervical mucus: This makes it harder for sperm to reach an egg.

Changing the uterine lining: It thins the lining of the uterus, making it less likely for a fertilized egg to attach.

Effectiveness and Weight Considerations

While Twirla is an effective method of birth control, its reliability can be affected by body weight. Clinical studies have shown that the patch may be less effective in women with a body mass index (BMI) of 25 or more. Twirla should not be used by women with a BMI of 30 or more, as the risk of pregnancy is higher and there is an increased risk of serious side effects like blood clots.

Usage for Contraception

To maintain its effectiveness as birth control, the patch must be replaced on the same day each week for three consecutive weeks. This is followed by a seven-day patch-free interval during which a withdrawal bleed (similar to a period) usually occurs. It is important to apply the patch to clean, dry skin on the abdomen, buttock, or upper torso (excluding the breasts).
