Yes, Cryselle is a combination birth control pill. Each active tablet contains two hormones: 0.3 mg of norgestrel (a synthetic form of progesterone) and 0.03 mg of ethinyl estradiol (a synthetic form of estrogen). Because it delivers both an estrogen and a progestin, it falls squarely into the “combination oral contraceptive” category rather than the progestin-only or “mini-pill” category.
What’s in a Cryselle Pack
A standard Cryselle pack contains 28 pills: 21 white active tablets followed by 7 light-green inactive (placebo) tablets. Every active pill delivers the same dose of both hormones, making Cryselle a monophasic pill. Some combination pills change hormone levels across the cycle (biphasic or triphasic), but with Cryselle the dose stays constant for all 21 active days. Your period typically arrives during the 7 placebo days.
How It Prevents Pregnancy
Cryselle works the same way other combination pills do: the two hormones together suppress the signals from your brain that trigger ovulation. Without ovulation, there’s no egg to fertilize. The progestin component also thickens cervical mucus, making it harder for sperm to reach the uterus, and thins the uterine lining so a fertilized egg would have difficulty implanting.
With perfect use, combination pills like Cryselle have a failure rate of about 0.3% in the first year. In typical use, which accounts for missed pills and late starts, that number rises to around 9%, according to CDC effectiveness data. The gap between those two numbers is almost entirely about consistency: taking the pill at roughly the same time every day and not skipping doses.
Common Side Effects
The most frequently reported side effects of Cryselle are ones shared by most combination pills:
- Irregular bleeding or spotting, especially in the first few months
- Nausea
- Headaches, including migraines
- Weight changes (gain or loss)
- Mood changes, including depression or nervousness
- Acne
- Fatigue
- Dark patches on the face (melasma)
Many of these ease after the first two to three cycles as your body adjusts to the hormones. Spotting between periods is particularly common early on and is not a sign the pill isn’t working.
Serious Warning Signs
Because combination pills contain estrogen, they carry a small but real risk of blood clots, stroke, and heart attack. Seek emergency care if you experience any of the following while taking Cryselle:
- Persistent leg pain or swelling that won’t go away
- Sudden severe shortness of breath
- Chest pain
- A sudden, severe headache that feels different from your usual headaches
- Sudden vision changes or blindness
- Weakness or numbness in an arm or leg
- Difficulty speaking
These can be signs of a blood clot, stroke, or pulmonary embolism and require immediate attention.
Who Should Not Take Cryselle
The estrogen in combination pills is the reason certain people are advised against them. Cryselle is contraindicated for anyone who:
- Smokes and is over age 35 (the risk of cardiovascular events rises sharply with both age and number of cigarettes)
- Has a history of blood clots in the legs or lungs
- Has coronary artery disease, uncontrolled high blood pressure, or diabetes with vascular complications
- Experiences migraines with aura at any age, or any migraines after age 35
- Has certain heart valve disorders or inherited clotting conditions
If any of these apply to you, a progestin-only pill, hormonal IUD, or non-hormonal method is typically a safer choice. The key distinction is that the estrogen component, the very thing that makes Cryselle a “combination” pill, is what drives most of these cardiovascular risks. Progestin-only options avoid that concern entirely.
