Pharmacist Tip

Unless you have been told otherwise by your prescriber, it is usually fine to start a new pack of pills straight after you have finished your last one, without a break, to delay your period. You should not run more than two packs together without advice from your doctor.

TriNovum is a phasic 21-day contraceptive pill containing the active ingredients ethinylestradiol and norethisterone. It helps to make it harder for the sperm to penetrate the womb and to reduce the chance of a fertilised egg implanting in the womb. Phasic 21-day contraceptive pills, like TriNovum, contain a combination of the hormones oestrogens and progestogens. They help to make it harder for the sperm to penetrate the womb and to reduce the chance of a fertilised egg implanting in the womb. If taken correctly they are over 99% successful at preventing pregnancy.

Trinovum is referred to as a combined oral contraceptive or ‘pill’. This is due to its two active ingredients; Ethinylestradiol and Norethisterone, which are synthetic versions of the female sex hormones Oestrogen and Progesterone. Combined oral contraceptives, such as Trinovum, work by over-riding a woman’s monthly menstrual cycle. During a natural menstrual cycle, the levels of oestrogen and progesterone change throughout the month. It’s these changes that trigger the various stages of the menstrual cycle. These sex hormones are responsible for ovulation, where an egg is released from the ovaries. They also trigger a change in the lining of the uterus, which helps prepare the womb for a potential pregnancy. If towards the end of this cycle an egg hasn’t been fertilised, the levels of sex hormones drop. This causes the lining of the womb to shed, which is commonly referred to as a woman’s monthly period.  

The synthetic hormones contained in Trinovum work by tricking the body into believing that ovulation has already occurred. This results in the ovaries not releasing an egg, as the body believes this has already happened. Trinovum also causes an increase in thickness of the natural mucus found at the neck of the womb. This will make it more difficult for sperm to penetrate beyond the vagina, making it less likely that any sperm will reach the womb. Trinovum tablets will also alter the consistency of the endometrium (lining of the womb). This change makes the lining less hospitable to fertilised eggs, thus decreasing the likelihood of an egg becoming implanted in it.

Trinovum is classed as a triphasic contraceptive. Each pack contains a 21 day supply, divided into three slightly differing types of tablets. Each of these three different types of tablets contain a slightly different dose of their synthetic hormones:

  • 7 white coloured tablets containing Ethinylestradiol 35mcg & Norethisterone 500mcg
  • 7 pale peach coloured tablets containing Ethinylestradiol 35mcg & Norethisterone 750mcg
  • 7 peach coloured tablets containing Ethinylestradiol 35mcg & Norethisterone 1mg

Every pack of Trinovum has these three variations of tablets arranged in the correct order. It is very important the tablets are taken in the correct sequence, starting with a white tablet marked with the day you start taking the pill. One tablet is then taken each day for twenty-one days. You will then need to have a seven day break from taking Trinovum. During this break, your hormone levels will drop, causing a withdrawal bleed that is similar to your natural monthly period. During the seven pill-free days you will still be protected against pregnancy, providing you took the tablets correctly and that you resume taking the next packet of Trinovum on time. You will resume taking a fresh pack of Trinovum after the seven day break is complete, even if you are still bleeding.  

Please read the Patient Information Leaflet for side effects and additional information.

Pharmacist Tip: TriNovum should be taken regularly at roughly the same time every day with a 7-day pill-free break after each pack. If you miss one pill anywhere in your pack, take it as soon as you remember even if it means taking two pills in a day. You should continue taking your pills as normal and you will not need additional contraception. If you miss more than one pill you will lose your contraceptive cover and extra contraception will be required for at least 7 days.

  • Start your packet of Trinovum with the first pill of the first colour (white).
  • Continue taking one pill at the same time each day, working your way around the pack following the arrows until it is finished. You should start with white, then light-peach and finially peach coloured tablets.
  • You should then have a 7-day break when you will have your period.
  • You should then start your new pack of pills on the 8th day (this will be the same day that you started your last new pack).

Missed Pill Advice

According to NHS Choices; if you have missed one pill, anywhere in the pack: 

  • take the last pill you missed now, even if it means taking two pills in one day
  • continue taking the rest of the pack as usual
  • you don’t need to use additional contraception, such as condoms
  • take your seven day pill-free break as normal

However, if you have missed two or more pills (you are taking your pill more than 48 hours late) anywhere in the pack: 

  • take the last pill you missed now, even if it means taking two pills in one day
  • leave any earlier missed pills
  • continue taking the rest of the pack as usual and use an extra method of contraception for the next seven days
  • you may need emergency contraception
  • you may need to start the next pack of pills without a break

Each white pill contains 500 micrograms norethisterone and 35 micrograms ethinylestradiol.

Each pale peach-coloured pill contains 750 micrograms norethisterone and 35 micrograms ethinylestradiol.

The contraceptive pill should not cause a harmful interaction with any of your other current medicines. Some medicines can reduce the effectiveness of the contraceptive pill including some antibiotics; these were checked during your online consultation. Please read the Patient Information Leaflet enclosed with your medicines for a full list of medicines that may affect your contraceptive pill.

While you’re taking TriNovum:

  • You will need regular check-ups with your doctor or family planning nurse, usually when you need another prescription of the Pill.
  • You should go for regular cervical smear tests.
  • Check your breasts and nipples every month for changes – tell your doctor if you can see or feel anything odd, such as lumps or dimpling of the skin.
  • If you need a blood test tell your doctor that you are taking the Pill, because the Pill can affect the results of some tests.
  • If you’re going to have an operation, make sure your doctor knows about it. You may need to stop taking the Pill about 4–6 weeks before the operation. This is to reduce the risk of a blood clot. Your doctor will tell you when you can start taking the Pill again. 
It is important to note that whilst taking Trinovum there is a small increased risk of suffering with a blood clot, stroke or heart attack and cancer of the cervix. It is important to have regular checks with your GP or contraceptive nurse to assess these risks.
