Aizea is a progesterone-only pill, otherwise known as a minipill. Distributed in the UK by Marlborough Pharmaceuticals, Aizea does not contain oestrogen, and is therefore less likely to cause side effects in those who have an increased sensitivity to this hormone. It is suitable for those who are breastfeeding, and when applied correctly, is almost as effective as the combined pill.

The way the treatment works is to mimic the function of progesterone in the body. Each month, the body goes through certain processes in order to ready itself for pregnancy. Most crucial among these is ovulation. This is the measure by which the ovary produces an egg and releases it into the fallopian tube. Here, it is ready to be fertilised by male sperm.

Desogestrel, which is the artificial version of progesterone found in Aizea, prevents this from happening. Ovulation occurs as a result of rising and falling levels of progesterone in the body. By replacing the levels of this hormone as they lower, desogestrel makes the body think that ovulation has already occurred. This stops an egg from ripening and being delivered into the womb.

Another function this hormone performs is to increase the density of vaginal mucus. This makes it harder for sperm to move around and reach an egg to fertilise it, thus providing a further protective measure. Most progesterone-only pills have this as their primary aim, and do not contain a dose which is strong enough to prevent ovulation. However, Aizea contains a level of the hormone which, in the majority of cases, stops the release of an egg.

It’s easy to buy Aizea from our secure online pharmacy. All you need to do is fill in our confidential medical survey, and we’ll take care of the rest. Upon completion, your answers will be checked by a registered UK practitioner. If your medication is safe for you, a prescription will be drawn up and sent electronically to our dispensing pharmacy.

Each order we fulfil is shipped by tracked parcel, so that you can relax in the knowledge that your order will arrive with you safely at your door within just one working day of successful consultation.
