Loryna is a combined birth control pill containing the active ingredients drospirenone and ethinyl estradiol. These hormones help protect against pregnancy within a few days. It can be up to 99% effective when taken accurately.[1]
Loryna may also help make periods lighter and reduce the uncomfortable PMS symptoms.
What doses of Loryna are there?
Loryna comes in one dose, containing 3mg of drospirenone and 0.02mg of ethinyl estradiol. It’s a low-dose pill suitable for women wanting light and short periods, less painful cramps, and fewer side effects.
It also has a lower risk of severe side effects, such as blood clotting, compared to high-dose pills.
Will I get side effects using Loryna?
You might get side effects while taking Loryna, including mood swings, nausea and headaches, but they should improve as your body adjusts to the treatment.
Loryna is a low-dose pill, so there’s a lower risk of side effects than other birth control pills.
How does Loryna compare with Yaz?
Loryna and Yaz are both pretty similar. They contain the same active ingredient in the same concentration, so they’ll be equally effective and work in the same way.
The main difference lies in the price, with Loryna being much cheaper than Yaz.
How does Loryna work?
Loryan contains synthetic progestin and estrogen. These hormones work in multiple ways to prevent pregnancy: they stop ovulation, thicken the cervical mucus to prevent sperm from reaching the egg, and prevent the buildup of the uterine lining, making it difficult to implant an egg.[2]

How to take Loryna
You should start taking Loryna on the first day of your period or the first Sunday after your period.
Loryna is simple to take:
Take one peach pill on days 1-24 with a glass of water.
Take it at the same time each day.
On days 25-28, take one white pill. During this time, you’ll get your period.
After finishing the white pills, take one peach pill even if you’re still bleeding.
When you start taking Loryna, take it on the first day of your period. This way, you won’t need to use an additional barrier contraceptive, like a condom, for seven days. If you take it on any other day, you’ll need to wear a condom for seven days while Loryna builds up protection.
If you’re switching from another birth control pill, check the package insert for more information.
How long does it take Loryna to work?
In most cases, it will take around a week to get maximum protection. Until that time, it’s best if you use a condom for seven days.
I missed a Loryna pill, now what?
If it’s been more than twelve hours since your last pill, your protection may be lost. You’ll likely need to use additional contraception for the next seven days. For more information, check the package insert.
If it’s been less than twelve hours, take it as soon as you remember. You should still have protection against pregnancy.
If you miss a white pill, you don’t need to worry. These are placebo pills and won’t affect your protection.

Loryna: 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.
How is Loryna different to other birth control pills?
Answer:
Loryna contains drospirenone, making it a fourth-generation birth control pill. Studies have shown that Loryna might be better than other pills when it comes to helping women control menstrual symptoms like vaginal dryness or mood changes.
Research has also found that it isn’t as likely to cause water and salt retention, which is why some women get weight fluctuations.[1]
Is Loryna similar to any other birth control pills?
Answer:
Loryna contains the same hormones in the same doses as a few other birth control pills, like Yaz, Gianvi, Vestura, and Jasmiel. But Loryna is cheaper than most of these other options, so you get the same benefits but at a lower price.
Is Loryna 3mg/0.02mg the only dose?
Answer:
Yes, there’s only one dose of Loryna. If you prefer a pill with the same hormones, but at a higher concentration, Ocella and Yasmin might be suitable for you. The higher concentration pills are better for women whose menstrual symptoms aren't controlled with Loryna.
Do I need a prescription for Loryna?
Answer:
Yes, you need a prescription for Loryna. A clinician will assess your medical history to make sure it’s suitable and safe for you.
While Loryna is safe for most women, if you have certain medical conditions or health risks, it's better to use a safer birth control method.
How effective is Loryna?
Answer:
Loryna is over 99% effective if taken correctly.[2] But in real life, because of human errors, such as taking a pill later or missing one or more pills, this efficacy drops.
If you forget to take a pill, it’s safer to use a barrier contraceptive method, such as a condom or spermicide, for the next seven days.
