What is Loestrin?
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.
What doses of Loestrin are there?
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.
How does Loestrin work?
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.

How to take Loestrin
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.
How effective is Loestrin?
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.
What happens if I miss a pill?
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.

Loestrin: FAQ
Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.
Does Loestrin cause weight gain?
Answer:
While we’ve all heard about weight gain associated with the pill, there haven’t been any scientific studies that were able to prove a connection. That’s because there are so many different elements that go into how much we weigh, and weight fluctuates a little every day.
There are two things that hormonal birth control can do that look like weight changes from the outside. Some pills can cause water retention, aka bloating — you’ve probably experienced this already during your cycle, and know what it’s like. Birth control pills can also impact your appetite, which might ultimately change your weight. The important thing to remember is that weight doesn’t magically appear or disappear. If you’re experiencing an uncomfortable amount of bloating with your birth control or noticing that it’s impacting your appetite, it might be time to try a different prescription. We’re here to help.
Does Loestrin help with acne?
Answer:
Loestrin can help with acne. The hormones in birth control like Loestrin decrease how much oil your skin produces, which can help control acne. There are even several birth control pills which are approved to treat acne in addition to preventing pregnancy. If you have issues with acne and you’d like your birth control to help, let the doctor know during your consultation so they can recommend the best option for all of your needs.
Does Loestrin stop your period?
Answer:
Loestrin can stop your period, but it’s not a guarantee. It’s likely you’ll have a shorter and lighter period while taking hormonal birth control, but it won’t necessarily stop. There are some forms of birth control that are more effective at stopping periods than others — let the doctor know during your consultation if you experience heavy periods you’d like help with or if you’re looking to stop having your period.
Is Loestrin generic?
Answer:
No, Loestrin is not a generic birth control. However, there are different versions of it, that have the same active ingredients, including Select, Minestrin, Norinyl and Lolo. The levels of hormones in these pills may differ slightly to Loestrin, and because different companies make them, the packaging and branding will be different too.
What about Lo Loestrin Fe?
Answer:
Lo Loestrin Fe is a low dose version of Loestrin which you can get in the USA, but isn’t available in Canada.
There is a pill available in Canada called Lolo, which is similar to Lo Loestrin. It’s got a unique 24-2-2 format. The first 24 pills are active pills with 1mg norethindrone acetate and 10mcg ethinyl estradiol. Then, the next two pills are also active but only contain the 10mcg of ethinyl estradiol. They have a different shape from the first 24 pills so you’ll be able to tell them apart. Finally, the last two are inactive pills.
Lolo is a good option if you’ve taken Loestrin and had mild side effects.
Why should I buy Loestrin with Treated?
Answer:
Our process is simple, convenient and centered around your health. And refills? They’re part of your Treated subscription, so you don’t have to worry about running out. At Treated, you’ll be able to consult with a doctor who will evaluate your medical history as well as what you’re looking for in a birth control and suggest options that would meet your needs but also be safe for you to take. While hormonal birth control is safe, generally, not all of it may be safe for you, specifically — that’s why it’s important to get help from an expert.
If you start a Treated birth control subscription, we’ll check in with you after a year just to make sure the medication is still working for you. However, we’re always available by chat so you can ask any questions you have, discuss side effects and even switch to a different medication if you’re having any issues with your birth control.
What are the alternatives to Loestrin?
Answer:
There are a lot of different birth control options available that are similar to Loestrin. Select, Minestrin, Norinyl and Lolo all contain the same hormones, but in different formulations (some are higher and some are lower dose).
Loestrin doesn’t have any exact equivalents available in Canada currently. Lolo is a lower dose alternative. Brevicon contains a slightly higher amount of estrogen but a lower amount of progestin, so that’s a close alternative too.
Another option is not a pill at all, but a vaginal ring. NuvaRing comes with a slightly different hormonal makeup, containing etonogestrel instead of norethindrone acetate, but releases 15mcg of ethinyl estradiol every 24 hours.
You can also skip the estrogen entirely and try a mini pill, which is a progestin-only birth control pill.
