TriNovum Contraception Pill
TriNovum Contraception Pill

TriNovum is a combined contraceptive pill that can be taken to avoid pregnancy.


TriNovum as a Contraception

TriNovum is a form of combined contraception that is taken to prevent unwanted pregnancy for women. It is an oral birth control pill to be taken consecutively for 21 days with a 7-day break or alternatively, depending on your consultation with the GP or doctor. It also helps alleviate symptoms of menstruation.

What is TriNovum and how does it work?

The pill contains synthetic progesterone and oestrogen. These hormones are also produced by the body. TriNovum works by altering the hormonal balance of the body to prevent ovulation by making the lining of the uterus less receptive to egg implantation.

Is this medication suitable for me?

Please get in touch with a doctor if you are unsure what medication is suitable for you. You can also complete our online consultation form to check your eligibility for the product.

How is the medication delivered?

All orders placed before 14:00 from Monday to Friday will be dispatched that day. The orders are sent using 24 Hour Tracked delivery provided by Royal Mail.

How many pills do you have to miss to get pregnant?

If you vomit or have diarrhoea within 2 hours of taking a pill, it may not have been fully absorbed into your system. You should take another pill straight away. If this happens more than once, contact your doctor for advice.

Missing one or two pills is unlikely to cause you to get pregnant. However, if you miss three or more pills, there is a greater chance that you could become pregnant. If you miss any pills, it is important to use another form of contraception, such as condoms, until you have taken a pill for 7 days in a row. This will help to reduce the risk of pregnancy.

How long does it take for Trinovum to become effective contraception?

It is important to take Trinovum exactly as your doctor tells you to. You will need to use another form of contraception, such as condoms, for the first 7 days of taking Trinovum. After this, it will start to work as a contraceptive.

Some products only require an online consultation which approximately takes 1 minute to complete, enabling you to then buy the product. Other products will also require a prescription; in this case, you will need to complete the online consultation, and then one of our partner pharmacy prescribers or doctors will review the online consultation questions and approve the order for delivery if you are eligible to purchase the item.
