Cilest contains two types of female sex hormones, oestrogen and progestogen. These hormones prevent an egg being released from your ovaries so you can’t get pregnant.

What is Cilest For?

Women who do not want to get pregnant and regulate their menstrual cycle are advised to take Cilest. This is a birth control pill containing progestogen and oestrogen – the synthetic versions of norgestimate and Ethinyl estradiol, which helps prevent pregnancy.

Cilest: How Does It Work? 

The two female sex hormones contained in Cilest are progestogen and oestrogen which works by preventing the release of an egg from the ovaries. This medicine also produces a thicker mucus in the cervix, making it more difficult for the sperm to reach the womb. All these actions prevent pregnancy.

Cilest: Benefits 

Cilest gives women some form of protection from unwanted pregnancies. This gets rid of the unnecessary worrying by women about getting pregnant after engaging in a sexual act.

The hormones in Cilest can also regulate the menstrual cycle, and for those who have severe symptoms, to stop the monthly period altogether.

Birth control pills are of two types: the progestogen-only pill, and the combined pill.

Cilest is classified as the combined pill and this is the more popular type of contraceptive because it is reliable and reversible. Furthermore, the medicine does not cause any side effects that will disrupt your sex life. If you are taking Cilest, your monthly period will become less painful and regular. 

Cilest: How Do You Use It? 

Your doctor will give you a prescription if he determines that Cilest is the right medication for you. Always follow the instructions of your doctor and read the information pamphlet that is enclosed in the medication package.

You can take the medicine orally and with a glass of water, even on an empty stomach.

For your initial treatment dose, you should take the first pill from the blister pack on Day 1 and up to Day 5 of your monthly period. This will ensure that you are immediately protected from getting pregnant.

If you start taking the pill later in your cycle, you must use other contraception methods like condoms, as it will take 7 days before the protection works.

If you are already taking a different pill but want to start on Cilest, you can take the pill anytime as long as you are not pregnant.

You will need to use additional contraception methods or barriers if you are on a non-hormonal birth control method and you take Cilest 5 days after your period started, until consuming the first 7 tablets correctly.

If you have just given birth to a baby and want to start on Cilest, you must consult with your doctor for advice as blood clots are more likely to happen during this time. Similarly, if you had a miscarriage or abortion, your doctor will advise you about using Cilest, if suitable for your condition.

Cilest comes in a packet that is complete with markings of the days of the week and arrows that will guide you on the direction of use. Choose your first tablet on the day of the week that you start. For example, if you start on a Wednesday, take the pill marked Wednesday on the first row. You must take the next tablet following the direction of the arrows. Take one pill per day until you have consumed the entire packet.

After consuming all the 21 pills in the packet, do not take Cilest for 7 days. Your protection against pregnancy is still in effect during this time as long as you are taking the tablets correctly.

Following the 7-day break, you must start on the next packet on the day following the day when the last pill was taken from the previous pack. If you took your last pill from the previous pack on a Friday, you should take Cilest on a Saturday for the next pack.

Expect to have some vaginal bleeding that is almost like a period during the 7-day break. Even if bleeding continues until the day you are to start Cilest on the next packet, you should still take the pill on the intended day.

Cilest: Dosage

Cilest is available in 35mcg of Ethinyl estradiol and 250mcg of norgestimate in film-coated tablets (35/250mcg).

The recommended dosage is one pill daily taken at approximately the same time each day for 21 days. Take 7 days no-pills break after the last of the 21 pills has already been taken. One packet is good for 4 weeks of consumption.

This birth control pill will be less effective if you miss taking a pill or if you start taking the pill late. If you have forgotten a dose, take the pill as soon as you remember. This will not have any effects on your protection.

If, on the other hand, you forgot more than one dose, or if you start a pack late more than a day, there is a chance that you are not protected against pregnancy.

In this case, take the most recent missed dose and leave the other pills you have forgotten to take in the pack. You are advised to use additional contraception like condoms for 7 days.

If you have severe diarhhoea, or if you are sick, you may not get enough hormones for your body from the Cilest pill.

If you have been sick 2 hours after taking the Cilest tablet, take a tablet from a spare strip. Continue taking the tablets as you would normally and you wouldn’t have to use additional contraception.

You can also delay your period. Consume the pills in the packet and begin the next packet on the day after the last pill from the previous packet was taken. This time continue taking the pills after 21 days, without the usual 7-day no pills break.
