What is Blisovi Fe?

Blisovi Fe is a combined birth control pill. That’s a pill which combines both of the hormones used in birth control: progestin (synthetic progesterone) and estrogen. The “Fe” in the name means the inactive pills contain an iron supplement. If you have an iron deficiency, the amount of iron in Blisovi Fe isn’t enough to treat it — but it’s a great bonus during your period week.

The specific hormones in Blisovi Fe are norethindrone acetate and ethinyl estradiol. You can learn more about the dosages and the different types of Blisovi Fe in the section right below.

What are the Blisovi Fe dosages?

EveAdam offers three different types of Blisovi Fe.

There’s Blisovi Fe 1/20 and Blisovi Fe 1.5/30. The numbers in those two refer to the amount of hormones. So Blisovi Fe 1/20 has 1mg of norethindrone acetate and 20mcg (that’s micrograms) of ethinyl estradiol, and Blisovi Fe 1.5/30 has 1.5mg of norethindrone acetate and 30mcg of ethinyl estradiol. They’re both what’s called a 21-day pack of birth control: you take the active pills for 21 days, and then inactive pills for 7 days.

Blisovi 24 Fe is a little different. The number in the name refers to the type of pack, in this case a 24-pack. That means you take the active pills for 24 days and then have just 4 days of inactive pills with the iron supplement. The hormone strength of Blisovi 24 Fe is the same as that of Blisovi Fe 1/20: the active pills contain 1mg of norethindrone acetate and 20mcg of ethinyl estradiol.

Do I need a prescription for Blisovi Fe?

Yes. All hormonal birth control, from the patch to the ring to the pill, requires a prescription. Normally you would call your doctor, attend an in-person appointment and then have to pick that prescription up at a pharmacy — it’s a lot of hassle for something so important. That’s why EveAdam does things a little differently.

After taking an online consultation with a licensed doctor and selecting your birth control from the list of options the doctor recommends for you, your prescription gets sent to our preferred pharmacy. Then they ship it directly to your door. Your EveAdam subscription includes refills, which are sent to you on a schedule you set.

How Blisovi Fe works

Hormonal birth control contains synthetic versions of hormones that are already in your body. Changing the amounts of these hormones changes how your body does certain things every month, keeping you safe from pregnancy.

Blisovi Fe will likely keep you from ovulating, which is when the ovary releases an egg. If there’s no egg, there’s no fertilization and definitely no pregnancy. Because ovulation doesn’t stop for everyone taking hormonal birth control, though, there are a few other things the pill does to make sure you’re protected. The mucus in your cervix grows thicker, which blocks sperm from getting through. And the lining of your uterine wall stays thin instead of building over the course of the month. Biologically, this means that a fertilized egg won’t have a comfortable wall to attach to. Practically, this means that you’ll experience a shorter, lighter period.

How to take Blisovi Fe

Like other hormonal birth control pills, Blisovi Fe is most effective when taken at the same time every day. Before you start your first pack, you should pick a time of day that will work for you every day of the week. That means that if you’re an early bird on weekdays but enjoy a lie-in on the weekends, an early morning time isn’t a great choice. You can set an alarm on your phone so you remember to take your pill but after a while, the routine should become easier to remember.

Depending on when you start taking the pill, it might not be immediately effective. We recommend using a back-up birth control method like condoms for the first 7 days, as you wait for the hormones to kick in.

Nausea is a possible side effect of Blisovi Fe. If you experience it, try taking your pill with a snack or small meal. Taking birth control with food isn’t a requirement, though. Feel free to take it with just a sip of water, or nothing at all (we won’t judge).

Because Blisovi Fe 1/20 and Blisovi Fe 1.5/30 are both 21-day packs, you’ll take active pills for the first three weeks and then finish with a week of inactive pills containing an iron supplement. The week when you’re taking the inactive pill is when you’ll get your period.

If you’re taking Blisovi 24 Fe, you’ll have 24 days of active pills followed by 4 days of inactive pills. Compared to Blisovi Fe 1/20 and 1.5/30, you might experience a shorter period.

Blisovi Fe side effects

Side effects can happen with any medication you take, including hormonal birth control. They range from mild, common ones to rare, severe ones — and most of the mild side effects will go away on their own as your body gets used to the new hormone levels.

Common side effects reported by women taking Blisovi Fe include acne, tender or painful breasts, water retention, dizziness, nausea, vomiting, spotting and irregular periods. With Blisovi 24 Fe, you might also experience cramping, bloating, increased vaginal discharge, increased hair growth, changes to your weight or appetite and decreased sex drive.

What types of Blisovi Fe are there?

EveAdam carries three types of Blisovi Fe.

Blisovi Fe 1/20 and Blisovi Fe 1.5/30 are different strengths of the same medication. Blisovi Fe 1.5/30 has a slightly higher dose of hormones. Both of these are combined birth control pills with 21 active pills and 7 inactive pills per pack, and both have iron supplements in their inactive pills. (That’s the “Fe” part — it’s the symbol for iron in the periodic table of elements.)

Blisovi 24 Fe is the same strength as Blisovi Fe 1/20: 1mg of norethindrone acetate and 20mcg of ethinyl estradiol in the active pills, and iron in the inactive pills. Blisovi 24 Fe comes with 24 active pills and 4 inactive pills. It’s thought that having a 24-4 pack will give you fewer hormone fluctuations over the month, which is a better option for some people. The doctor can help you pick which Blisovi Fe is right for you during your consultation.
