Low dose pill, with a break or not.

Loestrin is an effective combined hormonal birth control pill. You can get it as a 21 or 28 pack, depending on whether you want to take a pill free break or not.

Loestrin is a combined birth control pill. It’s called that because it contains two hormones, progestin and estrogen. If you take it exactly as it says in the leaflet, it’s over 99% effective at preventing pregnancy. When you make a mistake when taking Loestrin, it’s less effective but still gives you good cover as long as you follow the instructions on what to do if you miss a pill. It contains a fairly unique formulation of hormones, so there aren’t many other pills like it available.
There’s only one dose of Loestrin available in Canada: 1.5/30. You can get very similar pills in different doses. Pills that contain the same hormone but with variable amounts include: Minestrin, Select, Lolo and Norinyl. But because other versions of Loestrin contain different levels of hormone, they may not be as good as controlling symptoms you normally get around your period – so there’s this to consider if you’re thinking of switching.
The hormones in Loestrin keep your body from going forward with its monthly plans. Normally you’d experience ovulation, which is when the ovary releases an egg. Loestrin keeps this from happening — no egg means definitely no fertilized egg means no pregnancy.
Taking Loestrin also changes the mucus in your cervix, making it thicker so that sperm would have a harder time getting through. Your uterine lining plays a part as well. This lining normally builds over the course of the month in anticipation of possible pregnancy (like fluffing up the pillows when you’ve got guests coming) and is dispelled during your period. When you’re taking hormonal birth control, the lining doesn’t build in the same way, so your period will probably be shorter and lighter.

Loestrin birth control pills are more effective when they are taken at the same time every day. And this is birth control we’re talking about, so effectiveness is super important. Before you start taking your pills, pick a time that’ll be easy to stick to every day of the week. So if you get up at the crack of dawn on weekdays but sleep in on weekends, first thing in the morning might not be the best choice. (We like noon, personally, but it’s up to you.) If it’s hard for you to remember your pill every day, try setting a reminder on your phone — there are even apps to help you.
When you start taking Loestrin, it’s a good idea to use a back-up method like condoms for the first 7 days. This gives your body time to adjust to the pill and for its effectiveness to kick in, ensuring you’re as protected as possible.
You don’t have to take your birth control pill with food, but you might have an upset stomach when you start using it. Nausea is a common side effect of using Loestrin. If you experience nausea around the time you take your pill, try having it with a small meal or snack to help settle your stomach.
Loestrin 1.5/30 has 21 active pills you’ll take for the first three weeks followed by a week of inactive pills — that’s when you’ll have your period.
There isn’t a 100% effective birth control method, but Loestrin comes pretty close. When taken correctly, it’s around 99% effective. This means that if 100 women took Loestrin daily for a year, less than 1 woman would become pregnant.
By taking birth control correctly, we mean at the same time every day and as directed on the accompanying package insert. Correct use of birth control is how it’s done in clinical trials. But in day-to-day life, you’re more likely to take your pill “typically.”
Typical use considers things like taking your pill late or occasionally missing a pill. This lowers the effectiveness and your chances of being pregnant increase, so it’s important to stick to the routine as well as possible. If you’re finding yourself regularly forgetting pills, a non-daily method like the patch or ring might be better for you.
Missed pills can happen from time to time. Don’t panic — just get back on track as soon as possible.
If you miss one Loestrin pill, take it as soon as you remember. This could mean taking two in one day. After that, take one pill a day like normal.
If you miss two active pills in Week 1 or Week 2, take two pills a day for the next two days. After that, take one pill a day like normal. We recommend using a back-up birth control like condoms for a week to make sure you’re adequately protected.
If you miss two consecutive active pills in Week 3 (or if you miss three active pills in a row during any week), throw your pack away and start a new one that day. (If you’re a Sunday Starter, keep taking a pill each day until you reach Sunday and then start a new pack.)
When you miss a pill, the hormone levels in your body change and you might not get your period that month. If you don’t get your period the following month, though, you should take a pregnancy test.
