In the UK, nearly a quarter of women aged 16\u201349 are regular pill users\u00a0\u2013\u00a0it\u2019s a popular form of contraception.<\/p>\n
There are many pills available\u00a0and all are very effective. Combined oral contraceptive<\/a> (COC) pills are over 99% effective and the progesterone only pill (POP) or ‘mini pill<\/a>‘ is 97% effective\u00a0\u2013\u00a0so which one is right for you?<\/p>\n My first consideration is one of practicality.\u00a0Pills must be taken regularly. For those who work shifts, live between more than one place, are chaotic or prone to forgetfulness, the pill may not be reliable. The COC has more leeway regards missed pills as well as being more effective than the POP, so is usually chosen unless there are specific reasons not to.<\/p>\n To me, safety is the most important issue. Some women have medical conditions that can be worsened or triggered by the hormones in the pill<\/strong>. This is why your doctor or nurse will go through your medical history, and that of your close family. Your current medications, including over the counter herbal ones, will be looked at. Specifically, you will be asked about migraine, smoking, blood clotting issues including clots on the leg (both you and your relatives), as well as other conditions\u00a0such as\u00a0diabetes, cardiovascular disease, liver problems, Raynaud\u2019s disease, and systemic lupus erythematosus.\u00a0Your blood pressure will be measured, and your weight checked, and your age considered into this complicated equation. Presence of the above conditions (severity and number of them) determines whether and sometimes which pill is suitable.<\/p>\n If there are none of these potentially serious health issues restricting choice, then any pill can be prescribed. There are combined oral contraceptive pills which contain both oestrogen and progestogen, as well as the mini or progestogen only pill.<\/p>\n Most women are very happy being on the pill, both in terms of contraception and having regulated light periods or none at all. Some women experience side effects. It is not always possible to predict who this may be (and therefore some women will go on to change their pill).<\/p>\n Some COCs contain a fixed ratio of oestrogen to progestogen (monophasic) and some vary during the cycle. There are different ratios of oestrogen to progestogen in various pills as well as different forms of oestrogen and progestogen. These effect the side effect profile of each pill; some ratios are more likely to cause certain effects. The effects and (if experienced \u2013 most don\u2019t!) side effects are predictable from the contents of the pill.<\/p>\n The oestrogen in the combined pill controls periods better, break-through bleeding or irregular periods that are more likely in lower oestrogen pills or in the POP. Conversely, oestrogen induced nausea or headaches are less likely in lower oestrogen pills or in the POP. Breast tenderness sufferers may also benefit from a lower dose of oestrogen.<\/p>\n Some forms of progestogen are more likely to cause oilier skin and spots (so wouldn\u2019t be used in someone with acne).<\/p>\n Newer forms of progestogen have a greater risk than others of causing deep vein thrombosis (DVT), clots on the legs.<\/p>\n There is less evidence regarding effect of the pill on mood. Lifestyle and other factors need to be explored if mood disturbances occur. Changing the progestogen component to a newer form may help.<\/p>\n Weight gain cannot be attributed to the pill.<\/strong>\u00a0Exploring lifestyle and other factors is worthwhile, changing the pill is not. Other methods of contraception may be considered.<\/p>\n Some women may have a preference regarding pill brand; through previous own experience or friends’ recommendations.<\/p>\n Back to the original question, if none of these factors are present, as a starting point I prescribe a simple, inexpensive, monophasic pill, with a progestogen of the lower DVT risk.<\/p>\n Up to date guidance is available from MIMS – Table: Contraceptives<\/a><\/p>\nContraceptive pill types<\/h2>\n
