  1. 99% efficient protection
  2. Alternative for those who don’t like pills
  3. Removed after 3 weeks and replaced with a new one 7 days later


The contraceptive ring, known by its product name Nuvaring, is a pessary device made by Merck Sharp and Dohme. It is the only birth control treatment currently available in the UK which is supplied in this particular form. The ring is inserted into the vagina, and releases its dose gradually over a period of three weeks. It is then removed, and another is used to replace it after a week's rest period.

Please note that you will need to be shown in person how to insert Nuvaring by a doctor or nurse. If you have not used Nuvaring before or been shown how to insert it, we recommend you make an appointment with your GP. 

As it is only applied and removed at three week intervals, Nuvaring is seen by some as a more convenient and reliable form of contraception than regular pills. In the body, it performs a more or less identical function, by interfering with the process of ovulation, and making pregnancy less likely.

Every month, the ovary releases eggs which are then ripe for fertilisation by male sperm. Once successful contact has been made, the impregnated egg then journeys to the uterus, where it attaches to the uterine wall. It is here where the egg begins its development into an embryo.

The functioning substances in Nuvaring are ethinylestradiol and etonogestrel. These are synthesised versions of progesterone and oestrogen, biological hormones which regulate the monthly processes the body goes through in preparing for pregnancy. Collectively, they stop the ovary from generating an egg ready for insemination by sperm; alter the lining of the endometrium so that an egg is less able to adhere itself to the wall of the uterus; and amplify the density of cervical mucus, so that sperm are not as capable of movement inside the womb.

It is vital to be aware when buying medicine online of the rules and regulations trading pharmacies must follow, and the products they are allowed to sell. Nuvaring is at present only available as a branded treatment in the UK, and therefore no generic version has been licensed for use.

You can buy Nuvaring from our UK-registered pharmacy by taking our medical assessment. A doctor will review your case and if suitable, draw up a prescription for you. Once our dispensing partners have received this, your medicine will be dispensed and shipped to you in just 24 working hours.

Types of Treatments

Types of Treatment

Nuvaring is a contraceptive ring produced by Merck Sharp and Dohne. It is the only contraceptive ring currently available in the UK. The ring itself is small, around 5 cm in diameter and 4 mm thick, and made out of flexible plastic. It is designed to be inserted into the vagina and taken out after three weeks. After a 'no-ring' week, another ring is inserted and the treatment cycle is repeated.

How do they work?

Birth control rings work in an almost identical way to combined pills or patches. They contain a certain amount of synthetic hormones, which when released into the body helps to persuade it that ovulation has already taken place. This then means that the reproductive system does not produce an egg ready to be fertilised during the menstrual cycle.

What are the side effects?

As it contains the same active constituents, the side effects associated with Nuvaring are comparable to those of combined pills. Some of the more common among these are headaches, breast tenderness and slight abdominal pain. More detailed information can be found in the patient leaflet.

Can I take them with other medications?

This product may interact with other medicines. It is important to let your prescriber know which prescription, non-prescription or remedial treatments you are using so that they can accurately determine whether or not this contraceptive method is suitable for you.

Questions & Answers

What’s the difference between the medications?

Nuvaring contains the same hormones as the combined pill, and works in a very similar way. The main difference is in the way you apply it. Whereas oral contraceptives are taken every day, this ring is inserted and left to work for three weeks. It is then removed, and replaced by a new one a week later.

Should I use a ring or combined pills?

This depends on a range of factors, including your medical profile. Check with your doctor to find out which is the most suitable for you.

Are there different side effects?

The side effects associated with this treatment may slightly vary when compared to other hormonal contraceptive methods, but are mostly the same. Common side effects of this product include headache, feeling sick, and menstrual spotting or breakthrough bleeding. More comprehensive information can be found in the leaflet supplied.

Is it right for me?

Your GP or family planning nurse will be able to help you decide on the best form of contraceptive treatment. If you aren’t already using hormonal birth control, they will be able to initiate a prescription. Before using Nuvaring for the first time, a family planning nurse or a doctor will need to demonstrate how to use it.

If you are already using the contraceptive ring, getting your treatment renewed through our service is simple and easy. Our physicians are waiting to help you get access to the treatment you need. Simply select your medicine and complete our consultation. Following approval, your order will be shipped and delivered within one working day.
