2. After taking this product for more than 3 months, you should go to the hospital for examination. When taking this product, you should have a physical examination once a year, and explain to the doctor that you are taking this product.
3. Withdrawal bleeding usually occurs in the withdrawal period of 7 days, usually 2-3 days after the last medication, and may last until the next box of drugs is taken.
4. Please use it with caution in the following situations:
1) venous and arterial diseases.
A) The use of hormonal contraceptives is related to venous thrombosis (deep venous thrombosis and pulmonary embolism) and arterial thrombosis, sometimes with fatal results.
B) In COC users, the increased risk of venous thrombosis complications is related to the following factors:
-age;
-Positive family history (i.e. siblings or parents suffered from venous thromboembolism when they were relatively young). If it is suspected that it is a genetic factor, further examination is needed;
-Inability to walk, surgery (especially in the leg) and severe trauma. In these cases, it is recommended to stop COC (at least 4 weeks in advance if it is elective surgery) and use it again after two weeks of full activity;
Obesity (body mass index over 30kg/m [sup] 2 [/sup]);
-It may also include spontaneous superficial phlebitis and varicose veins. There is no consensus as to whether these diseases are the causes or promoting factors of deep vein thrombosis.
C) The increased risk of arterial thrombosis complications is related to the following factors:
-age;
-Smoking (if women over 35 want to use COC, they should be advised to quit smoking);
Abnormal lipoproteinemia;
Obesity (body mass index over 30kg/m [sup] 2 [/sup]);

2) Tumors: The most important risk factor for cervical cancer is human papillomavirus (HPV) infection. It has been reported that the risk of cervical cancer in women who take compound oral contraceptives for a long time increases, but how much should be attributed to the mixed effect of other factors (such as cervical cancer screening and sexual behavior including barrier contraception) is still controversial; The analysis of epidemiological research reports shows that the relative risk of breast cancer diagnosis rate will increase slightly, but these studies do not provide conclusive evidence; Occasionally there are reports of benign liver tumors; There are also rare reports of malignant liver tumors in women taking compound oral contraceptives.
3) Other circumstances:
A) Women with hypertriglyceridemia or family history may increase the risk of pancreatitis when taking compound oral contraceptives.
B) It is reported that many women who take compound oral contraceptives may have a slight increase in blood pressure.

5. If pills are missed, gastrointestinal reactions or some drugs are combined, the curative effect may be reduced.

7. Disposal of lost clothes
A) If you miss it within 12 hours, the contraceptive effect will not be reduced. Once you think of it, take it immediately and take it regularly 1 tablet. If you miss more than 12 hours, the contraceptive effect may be reduced, and the following suggestions can be made to deal with it:
* The service leak occurred in the first week.
Take the missed medicine as soon as you think of it (even if you take two tablets at the same time). Take one tablet at a fixed time. For the next 7 days, take barrier contraception (such as condoms) at the same time. If you have sex in the first 7 days, you may get pregnant. The more pills you miss, the closer you get to the withdrawal period, the higher the risk of pregnancy.
* The service leak occurred in the second week.
Eat as soon as you think, even if you eat two tablets at the same time. Then take the rest of the pills at the specified time. If you take the pill correctly for 7 days before missing it, you don't need to take other contraceptive measures. If you don't take the correct medicine for 7 consecutive days or miss more than one tablet, it is recommended to use barrier contraception at the same time in the next 7 days.
* The service leak occurred in the third week.
Method 1: Eat as soon as you think of it, even if you eat two tablets at the same time. Take the remaining pills at a fixed time. Once this box of medicine is finished, I will start taking the next box immediately, so there is no withdrawal period during this period. There may be no withdrawal bleeding before taking the second box of medicine, but there may be drip bleeding or breakthrough bleeding during taking the medicine.
Method 2: You can also stop taking this box of medicine for 7 days (including the day when the tablets are missed), and then continue to take the next round.
If a woman misses oral contraceptives and there is no withdrawal bleeding during the withdrawal period, the possibility of pregnancy should be considered.
B) treatment of vomiting
If you vomit within 3-4 hours after taking the medicine, the effective components of the medicine may not be completely absorbed. It's like missing a pill. Therefore, according to the section "How to deal with missed service", it is still handled according to the doctor's advice. If you don't want to change the normal medication order, you can take more pills from the next box.
