What is Camrese birth control?

Camrese is a (deep breath) extended-cycle biphasic combined birth control pill.

Come again?

We know, it’s a mouthful. So let’s break that down.

Your typical birth control pill comes in a pack of 28. Camrese comes in a pack of 91. That’s the “extended-cycle” bit — you’re extending the length of time you’re taking active hormones. (This means you’ll get your period every 3 months instead of every month. Score.)

Your typical birth control pill is also monophasic: you get one (mono) dose of hormones in all your active pills. Camrese is biphasic so you get two (bi) doses of hormones throughout the month. This is thought to more naturally mimic your body’s cycle, and can lower the risk of side effects.

Combined birth control contains both of the hormones you’ll find in birth control: progestin and estrogen. And in this case, it comes in the form of a pill you take every day.

So Camrese is an extra-big pack of pills. You’ll take it for three months before having your period. It’s got both progestin and estrogen, and the amounts change over the course of the month. We think it’s a pretty great birth control.

What is Camrese Lo?

Camrese Lo is an option if you prefer an even lower dose of hormones. Generally, a birth control is considered low dose if it has less than .03mg of estrogen.

Regular Camrese has .03mg of ethinyl estradiol (an estrogen) in the first 84 pills and .01mg in the last 7 pills.

Camrese Lo has .02mg of ethinyl estradiol in the first 84 pills and .01mg in the last 7 pills. It also has a little bit less levonorgestrel, the progestin, which is only in the first 84 pills.

Some women may benefit from taking a lower-dose birth control. Talk to the doctor during your consultation to see if Camrese Lo is right for you.

Do I need a prescription for Camrese?

Hormonal birth control is prescription-only in the US, but that doesn’t mean getting it has to be difficult. At EveAdam, we want to make it simple for you to be protected — and stay protected. Take one of our consultations and a licensed doctor will help you choose a birth control that works for you.

What is the dosage of Camrese?

Camrese is available in two strengths, regular Camrese and Camrese Lo. We offer both of these at EveAdam.

Because Camrese is a biphasic pill, you get one dose of hormones (levonorgestrel and ethinyl estradiol) for the first 84 pills and then a different dose (just the ethinyl estradiol) for the last 7.

If you’re taking regular Camrese, your first 84 pills have .15mg levonorgestrel and .03mg ethinyl estradiol. The last 7 pills have .01mg ethinyl estradiol.

Camrese Lo has .1mg levonorgestrel and .02mg ethinyl estradiol in the first 84 pills, and .01mg ethinyl estradiol in the last 7.

How to take Camrese

Take Camrese at the same time every day. None of the pills in your pack are inactive (without hormones) so it’s important you don’t skip a pill. Before starting Camrese, pick a time that works for you and your schedule, every day of the week.

Most women take Camrese with a sip of water but if you experience any nausea or stomach upset this way, try having your daily pill with a snack or small meal.

Your Camrese pack comes with 91 total pills. It’s in an extended-cycle pack which looks like three conventional birth control packs attached to each other. The first two will have 28 pills (four weeks) in each of them and the last pack has an extra week of estrogen-only pills. That’s when you’ll have your period, before starting a new extended-cycle pack.

Does Camrese birth control have side effects?

Yes, Camrese can cause side effects. Most of the common side effects are mild and will go away on their own, and any serious side effects are very rare. However, it’s still important to know what they are so that you’re able to see a doctor if you experience any of them. Here’s what to look out for.

Is Camrese generic?

Yes. Camrese is the generic version of Seasonique. It’s made by Teva.

There are other extended-cycle birth control pills with the same formulation as Camrese and Seasonique. They include Amethia, Daysee, Ashlyna and Jaminess.

Generics are all equally effective but will likely look different and have different prices — and while the active ingredients (hormones) are the same, they may have other inactive ingredients.

Camrese warnings

Camrese isn’t a good choice for everyone. Don’t take Camrese if you’ve ever had breast cancer or another cancer sensitive to female hormones, liver disease, a prescription for a Hepatitis C drug containing ombitasvir/paritaprevir/ritonavir, blood clots or clotting disorders, a stroke or heart attack or severe migraines with aura.

You also shouldn’t take Camrese if you are over 35 years old and smoke. If you’re over 35, a progestin-only birth control would be better for you.

Don’t take Camrese if you are or think you might be pregnant.
