Trinovum is a triphasic combined oral contraceptive pill. This means that you will take three different doses during your cycle to reduce side effects, such as bleeding, spotting, mood swings, and amenorrhea (absence of a period). Trinovum doesn't only provide contraceptive cover, but is also a known treatment for endometriosis and can be prescribed to women who have irregular, heavy or painful periods.
How does the Trinovum pill work?
Trinovum uses two synthetic hormones, ethinylestradiol (oestrogen) and norethisterone (progestogen) to influence your body's natural cycles. This is because it supplements your body with the hormone levels released during and after ovulation, so that your body thinks it has already occurred and that an egg has already been released.
The womb lining is also prevented from thickening, so should an egg be released, it won't be able to embed itself. As an additional measure, the hormones prevent semen from entering the womb by thickening the cervical fluid.

What are the benefits of Trinovum?
Triphasic oral contraceptives prevent pregnancy with three different doses. This allows the amount of hormones taken to rise and lower, depending on which stage of your menstrual cycle you are experiencing. Because it adapts to your natural cycle, the chance of you experiencing side effects such as bleeding, spotting, mood swings and missed periods (amenorrhea) is significantly reduced.
Trinovum provides immediate contraceptive cover if you take it on the first day of your cycle. Because it's a combined contraceptive, Trinovum can also help to reduce period pains and make your periods more regular. It's also used as a treatment for endometriosis, a common problem where womb cells grow outside of the womb on other cells.
Does Trinovum protect me against STIs?
No. Trinovum tablets will not protect you against any sexually transmitted diseases/infections. If you've had had unprotected sex and are worried you might have contracted an STI, you should talk to your GP or visit your local sexual health clinic.
Alternatively, you can take a look at some of the options available from HealthExpress.
How do I take the Trinovum pill?
Trinovum is triphasic, which means that you take pills containing different doses of the active ingredients at different times in your cycle. You must take these pills in order that is suggested on the packaging. Trinovum is a 21 day pill, which means that there is a seven day break between 21 day strips. You will still be completely protected for those seven days.
For immediate cover you should start taking this contraceptive on the first day of your period. You start by taking seven white tablets containing 35 micrograms ethinylestradiol and 0.5 milligrams norethisterone, followed by seven light peach tablets containing 35 micrograms ethinylestradiol and 0.75 milligrams norethisterone. And you finish the course with seven darker peach tablets containing 35 micrograms ethinylestradiol and 1 milligram norethisterone.
If not taken on the first day of your period, use condoms for the following seven days.Take each pill around the same time every day for maximum effectiveness of over 99%. Many women set an alarm to remember their next dose.Each Trinovum pill can be easily swallowed with or without drink and food.Store away from direct sunlight and under the temperature of 25°C.Double check the expiry date and patient leaflet regarding use and missed pill if unsure.
What happens if I miss my dose of Trinovum?
If you happen to forget to swallow your Trinovum pill at the scheduled time, take is as soon as you remember. However, if you realise that you've missed it by 24 hours or more, it is advised to follow these instructions:
If you have missed one Trinovum tablet, then take it as soon as you can. Sometimes this might mean taking two pills at the same time. After this has been done, you can then continue taking the rest of the pack as instructed by your doctor.
If you miss two or more Trinovum pills, then you will be at risk of falling pregnant should you engage in unprotected intercourse. However, take the missed pill as soon as you remember. Sometimes this may mean taking two tablets at the same time. Due to the way the treatment works, you're advised to use condoms or other forms of contraception for the next seven days.
If you have less than seven pills left in your packet of Trinovum, then you should finish it and then start a new one straight away without a break.
If you have seven or more pills left in the pack, you should finish it and have your normal 7-day break before opening the next one.
