1. What Levonorgestrel/Ethinylestradiol pensa is and what it is used for

• Levonorgestrel/Ethinylestradiol pensa is a combined oral contraceptive tablet used to prevent pregnancy. It contains two different female hormones, levonorgestrel and ethinylestradiol.
• Each of the 21 pink tablets contains 100 micrograms of levonorgestrel and 20 micrograms of ethinylestradiol.

2. What you need to know before starting to take Levonorgestrel/Ethinylestradiol pensa

Before you start taking Levonorgestrel/Ethinylestradiol, your doctor will ask you several questions about your medical history and personal relationships. Your doctor will also measure your blood pressure and may perform other tests.

This leaflet describes certain situations in which you should stop taking Levonorgestrel/Ethinylestradiol or where its effectiveness may decrease, increasing the risk of pregnancy. In these situations, you should avoid sexual intercourse or use additional non-hormonal contraceptive precautions (e.g., condoms or other barrier methods). Do not use the rhythm method or temperature method. These methods may not be reliable because Levonorgestrel/Ethinylestradiol alters monthly changes in body temperature and cervical mucus.

Levonorgestrel/Ethinylestradiol pensa, like other oral contraceptives, does not protect against HIV infection (AIDS) or other sexually transmitted diseases.

Do not take Levonorgestrel/Ethinylestradiol pensa

• If you have or have had heart problems or blood vessel disorders, particularly:
  • Heart attack (myocardial infarction), irregular heartbeat, or heart valve disorders.
  • Blood clots in the legs (deep vein thrombosis), in the lungs (pulmonary embolism), or rupture of blood vessels in the brain (stroke), mini-stroke, or a general tendency to form blood clots (venous or arterial thrombosis).
  • Chest pain caused by angina pectoris.
• If you have uncontrolled high blood pressure despite treatment.
• If you suffer from certain types of migraine (migraine with focal neurological symptoms).
• If you have hepatitis C and are taking medications containing ombitasvir/paritaprevir/ritonavir and dasabuvir, glecaprevir/pibrentasvir, or sofosbuvir/velpatasvir/voxilaprevir (see also section “Other medicines and Levonorgestrel/Ethinylestradiol pensa”).
• If you have or have had a benign or malignant liver tumor, or if you recently had liver disease. In such cases, your doctor will ask you to stop taking Levonorgestrel/Ethinylestradiol until your liver function returns to normal.
• If you have breast cancer, uterine cancer, or any cancer sensitive to female hormones, or if such cancer is suspected.
• If you have vaginal bleeding of unknown cause.
• If you have high blood sugar levels (diabetes) associated with blood vessel complications.
• If you are pregnant or suspect you might be.
• If you are allergic to the active substances (levonorgestrel or ethinylestradiol) or to any of the other ingredients of this medicine (listed in section 6).

This medicine contains soy lecithin. It should not be used if you are allergic to peanuts or soy.

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to take Levonorgestrel/Ethinylestradiol.

Special care may be needed when taking Levonorgestrel/Ethinylestradiol or any combined oral contraceptive. Your doctor will routinely monitor you. Smoking increases the risk of serious adverse effects on the heart and blood vessels associated with the use of oral contraceptives. This risk increases with age and the number of cigarettes smoked and is particularly significant in women over 35 years of age. Women using oral contraceptives should not smoke. Women over 35 who smoke should consider using alternative contraceptive methods.

If you have any of the following conditions, inform your doctor before starting Levonorgestrel/Ethinylestradiol. If any of the conditions listed below develop or worsen while taking Levonorgestrel/Ethinylestradiol, you must consult your doctor to determine whether Levonorgestrel/Ethinylestradiol remains suitable for you:

Inform your doctor if:

• You have high blood pressure.
• You have high cholesterol levels or abnormal blood lipid (fat) levels (dyslipidemia) – these are detected in a blood test.
• You have diabetes.
• You are obese.
• You have heart valve problems or irregular heartbeat (atrial fibrillation).
• You or a close relative (parent, sibling) have had a condition predisposing to blood clots (in the legs, lungs, or elsewhere in the body), or have a history of heart attacks or strokes.
• You have varicose veins or have had inflammation in the superficial leg veins.
• You experience a sudden and unexplained change in vision.
• You have gallstones, gallbladder disorders, or problems caused by blockage of the bile ducts (cholestasis) – this may cause intense itching.
• You develop migraine for the first time or experience worsening of existing migraines.
• You have or develop liver disease, jaundice, pancreatitis, or kidney disorder.
• You have depression.
• You have hearing loss due to a condition known as otosclerosis.
• You have ever had a blood disorder called porphyria.
• You have had ulcerative colitis or Crohn’s disease (intestinal inflammation causing abdominal pain, frequent diarrhea, and fatigue).
• You have ever had a blood disorder associated with kidney disease (hemolytic uremic syndrome).
• You have a condition known as Sydenham’s chorea. Symptoms include sudden, irregular, involuntary movements.
• You have a disorder affecting your immune system (systemic lupus erythematosus).
• You have had a skin condition during pregnancy or while taking another contraceptive pill causing itching, red spots, or blisters (herpes gestationis).
• You developed temporary brown patches on your skin during pregnancy (chloasma). The pill may cause this to recur, so you should avoid sun exposure or sunbathing while taking Levonorgestrel/Ethinylestradiol.
• You have a blood disorder called sickle cell disease (also known as sickle cell anemia).
• You experience symptoms of angioedema such as swelling of the face, tongue and/or throat, and/or difficulty swallowing, or hives with possible breathing difficulties, contact a doctor immediately. Products containing estrogens may cause or worsen symptoms of hereditary or acquired angioedema.

Psychiatric disorders

Some women using hormonal contraceptives such as Levonorgestrel/Ethinylestradiol have reported depression or depressed mood. Depression can be severe and may sometimes lead to suicidal thoughts. If you experience mood changes or depressive symptoms, contact your doctor for medical advice as soon as possible.

If you have hereditary angioedema, products containing estrogens may cause or worsen angioedema symptoms. You should seek immediate medical attention if you experience symptoms such as swelling of the face, tongue and/or throat, difficulty swallowing, or hives accompanied by breathing difficulties.

Levonorgestrel/Ethinylestradiol pensa and thrombosis (blood clots)

Venous thrombosis (blood clots)

The use of any combined oral contraceptive pill, including Levonorgestrel/Ethinylestradiol, increases the risk of venous thrombosis (formation of blood clots in blood vessels) in women compared to women not taking any contraceptive pill.

The risk of venous thrombosis in women taking combined oral contraceptives increases:

• with age,
• if you are overweight,
• if a close relative has had a condition predisposing to blood clots at a young age,
• with prolonged immobilization (e.g., one or both legs in casts or splints), major surgery, any type of leg surgery, or major trauma. In such cases, it is advisable to stop taking Levonorgestrel/Ethinylestradiol (if surgery is planned, stop at least four weeks beforehand) and not restart until two weeks after you can walk normally again,
• immediately after childbirth, women have an increased risk of blood clots, so you should consult your doctor about when you can start taking the combined pill again.

Arterial thrombosis (or blood clots)

The use of combined oral contraceptives has been associated with an increased risk of arterial thrombosis (blockage of an artery), for example, in blood vessels of the heart (heart attack) or brain (stroke).

The risk of arterial thrombosis in women taking combined oral contraceptives increases:

• If you smoke. You are strongly advised to stop smoking while taking Levonorgestrel/Ethinylestradiol, especially if you are over 35 years old.
• With age, even if you do not smoke.
• If you have increased fat levels in the blood (cholesterol or triglycerides).
• If you are overweight.
• If a close relative has had a heart attack or stroke at a young age.
• If you have high blood pressure.
• If you have migraines.
• If you have heart problems (valve disorders or irregular heart rhythms).

Stop taking Levonorgestrel/Ethinylestradiol pensa and consult your doctor immediately or go to the nearest hospital emergency department if you experience possible signs of thrombosis, such as:

• Severe pain and/or swelling in one of your legs.
• Sudden severe chest pain that may spread to the left arm.
• Difficulty breathing or sudden shortness of breath.
• Sudden unexplained cough.
• Unusual, severe, or prolonged headache, or more frequent or severe migraine attacks.
• Increased blood pressure.
• Changes in vision, partial or complete blindness, or double vision.
• Difficulty speaking, or inability to speak.
• Sudden changes in hearing, sense of smell, or taste.
• Dizziness or fainting.
• Weakness, unusual sensations, or numbness in any part of the body.
• Sudden severe stomach pain.

Levonorgestrel/Ethinylestradiol pensa and cancer

Breast cancer has been diagnosed slightly more frequently in women using combined oral contraceptives, but it is unknown whether the pill causes it. It is possible that these women are simply examined more thoroughly and frequently, making earlier detection of breast cancer more likely. Studies have reported cases of cervical cancer in women who have taken combined oral contraceptives for a relatively long time. It is currently unknown whether this is caused by the pill or related to sexual behavior (e.g., more frequent partner changes) and other factors.

Rarely, benign liver tumors and even a few cases of malignant liver tumors have been reported in patients taking oral contraceptives. Contact your doctor if you have unusual, severe abdominal pain.

Bleeding between periods

During the first few months of taking Levonorgestrel/Ethinylestradiol, you may experience unexpected bleeding (spotting or breakthrough bleeding outside the tablet-free week). If this bleeding lasts longer than a few months or begins after several months, your doctor should investigate the cause.

What to do if there is no bleeding during the tablet-free week

If you have taken all the tablets correctly, have not had vomiting or severe diarrhoea, and have not taken any other medicines, it is very unlikely that you are pregnant.

If your period does not occur for the second time in a row, you may be pregnant. Consult your doctor immediately. Do not start the next pack until you are sure you are not pregnant.

Other medicines and Levonorgestrel/Ethinylestradiol pensa

Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines.

Some medicines may interact with Levonorgestrel/Ethinylestradiol.

Medicines can sometimes interfere with each other. If you are being treated by another doctor, nurse, or qualified healthcare professional, make sure they are aware that you are taking Levonorgestrel/Ethinylestradiol as a contraceptive. They may advise you whether additional contraceptive precautions (e.g., using condoms or other barrier methods) are necessary while you are taking other medicines together with Levonorgestrel/Ethinylestradiol.

Some medicines may make Levonorgestrel/Ethinylestradiol less effective in preventing pregnancy or may cause unexpected bleeding. These include medicines used to treat:

• epilepsy (e.g., phenobarbital, primidone, phenytoin, felbamate, carbamazepine, oxcarbazepine, or topiramate)
• infections (e.g., rifampicin, rifabutin, or griseofulvin)
• HIV infection (ritonavir, nevirapine)
• St. John’s wort (Hypericum perforatum), used to treat certain types of depression
• gout (phenylbutazone)
• sleep disorders (modafinil).

If you have been advised to take additional contraceptive precautions while taking any of the medicines listed above, follow your doctor's instructions carefully. If you need to continue taking the medicine after finishing your current pack, do not take the tablet-free week and start a new pack immediately.

In some cases, you may need to continue using an additional barrier contraceptive for several weeks after stopping the medicine.

Levonorgestrel/Ethinylestradiol may interfere with the following medicines:

• cyclosporine (used to reduce the immune response)
• lamotrigine (used to treat epilepsy).

Taking an antibiotic called troleandomycin may increase the risk of intrahepatic cholestasis (bile retention in the liver) during treatment with the combined pill.

Taking a medicine called flunarizine, used for migraine prevention, may increase the risk of galactorrhoea. This is a condition in which the breasts spontaneously secrete milk without breastfeeding or recent childbirth.

Do not take Levonorgestrel/Ethinylestradiol if you have Hepatitis C and are taking medications containing ombitasvir/paritaprevir/ritonavir and dasabuvir, glecaprevir/pibrentasvir, or sofosbuvir/velpatasvir/voxilaprevir, as these medicines may cause increases in blood liver function parameters (elevated liver enzyme ALT).

Your doctor will prescribe another type of contraceptive before starting treatment with these medicines.

Levonorgestrel/Ethinylestradiol may be restarted approximately 2 weeks after completing this treatment. See the section “Do not take Levonorgestrel/Ethinylestradiol pensa”.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you might be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.

Do not take Levonorgestrel/Ethinylestradiol if you are pregnant. If you think you may have become pregnant while taking Levonorgestrel/Ethinylestradiol, consult your doctor immediately.

The combined pill is not recommended while breastfeeding, as hormones may affect breast milk. If you wish to breastfeed, your doctor will advise you on suitable alternative contraceptive methods.

Always consult your doctor, nurse, or healthcare professional before using any medicine.

Driving and using machines

The effect of Levonorgestrel/Ethinylestradiol on the ability to drive or use machines has not been studied. Dizziness has been reported as an adverse effect. If you experience dizziness, do not drive or use machines until symptoms resolve.

Levonorgestrel/Ethinylestradiol pensa contains lactose and soybean lecithin

This medicine contains lactose. If your doctor has informed you of an intolerance to certain sugars, consult them before taking this medicine.

This medicine contains soybean lecithin. It must not be used if you are allergic to peanuts or soybeans.

3. How to take Levonorgestrel/Ethinylestradiol pensa

Follow exactly the instructions for use of this medicine as given by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.

Each Levonorgestrel/Ethinylestradiol pensa blister pack contains 21 tablets. Take the first tablet from the blister on the day corresponding to the correct day of the week. You must take one tablet every day, with water if necessary, at the same time each day, until the pack is finished. Then you will have a tablet-free week before starting the next pack. You must always start the next pack on the same day of the week.

During the tablet-free week, you will experience a withdrawal bleed similar to a period. This bleeding usually starts after two or three days and may not have finished before you start the next pack of tablets.

If this is the first time you are starting a pill or you have not used any hormonal contraceptive in the previous month

Take the first tablet on the first day of your period. If you start after the first day of your period (on days 2–7 of the cycle), you must use an additional barrier method (e.g., condoms) for the first 7 days.

If switching from a combined oral contraceptive pill

If you are currently taking a 21-tablet pack

Finish the current pack and start taking Levonorgestrel/Ethinylestradiol pensa the next day, without a break.

If you are currently taking "daily" pills containing 28 tablets per pack

If your current pill pack contains inactive (placebo) tablets, do not take these tablets and start Levonorgestrel/Ethinylestradiol pensa immediately the next day, without any break.

If switching from a progestogen-only pill, an injection, or an implant

• If switching from a progestogen-only pill, you may start Levonorgestrel/Ethinylestradiol pensa at any time during the menstrual cycle, the day after stopping the progestogen-only pill.
• If switching from an implant, start using Levonorgestrel/Ethinylestradiol pensa the day after removal of the implant.
• If switching from a contraceptive injection, start Levonorgestrel/Ethinylestradiol pensa the day after the next scheduled injection would have been due.

In all cases, you must use a barrier contraceptive method for the first 7 days of taking the pill.

If starting Levonorgestrel/Ethinylestradiol pensa after a first-trimester abortion (within the first 3 months of pregnancy)

You may start taking Levonorgestrel/Ethinylestradiol pensa immediately, but you should follow your doctor's advice before doing so. No additional barrier contraceptive method is needed.

If starting Levonorgestrel/Ethinylestradiol pensa after childbirth or after a second-trimester abortion

Like any other contraceptive pill, Levonorgestrel/Ethinylestradiol pensa should not be started earlier than 28 days after giving birth or after a second-trimester abortion, as the risk of blood clots is increased. If you start later, you are advised to use a barrier contraceptive method for the first seven days of taking the pill. If you have had sexual intercourse before starting Levonorgestrel/Ethinylestradiol pensa, make sure you are not pregnant or wait until your next period.

If in doubt, always consult your doctor.

If you take more Levonorgestrel/Ethinylestradiol pensa than you should

If you accidentally take more Levonorgestrel/Ethinylestradiol pensa than you should, you may experience symptoms including gastrointestinal disturbances (e.g., nausea, vomiting, abdominal pain), breast tenderness, dizziness, drowsiness/fatigue, and vaginal bleeding. These symptoms will naturally subside as your body processes the excess hormones.

If you are concerned, consult your doctor.

Contact your doctor or pharmacist immediately or call the Toxicology Information Service at telephone number: 91 562 04 20, indicating the medicine and the amount ingested.

If you forget to take Levonorgestrel/Ethinylestradiol pensa

If you forget to take a tablet, there is a risk you may become pregnant

• If you realize you have forgotten a tablet within 12 hours of your usual time, take the missed tablet immediately and continue as normal, taking the following tablets at the usual times until the pack is finished.
• If you realize you have forgotten a tablet more than 12 hours after your usual time, there is a risk you may become pregnant. In this case:
  • Take the last missed tablet immediately, even if this means taking two tablets in one day.
  • Continue taking the tablets until the end of the pack.
  • Additionally, use a barrier contraceptive method (e.g., condom) for the next 7 days.
  • If this 7-day period extends beyond the last tablet of the pack, start the next pack immediately without a break. You may experience spotting or bleeding while taking the second pack, but this is not a cause for concern.

If you have missed one or more tablets in a pack and do not have any bleeding during the tablet-free week, you may be pregnant and should consult your doctor.

If you experience vomiting or diarrhoea

If you vomit or have severe diarrhoea within 4 hours of taking a tablet, this is considered the same as missing a tablet. After vomiting or having diarrhoea, you should take another tablet from the reserve blister pack as soon as possible. If possible, take it within the next 12 hours or at your usual pill-taking time. If this is not possible or if more than 12 hours have passed, you should follow the advice given under "If you realize you have forgotten a tablet more than 12 hours after your usual time."

If episodes of vomiting or severe diarrhoea recur over several days, a barrier contraceptive method (e.g., condoms) should be used until the start of the next pack. Consult your doctor if in doubt.

How to delay your period

You can delay your period by starting another pack of Levonorgestrel/Ethinylestradiol pensa immediately, without a break. You may experience some spotting or bleeding while taking the second pack, but this is not a cause for concern. You should have a normal bleed after finishing the second pack.
