Month: May 2023

Birth control pills have been safely used in the US (and sold only by prescription) for more than half a century. Just this past summer, the FDA approved Opill, the first daily contraceptive pill intended for sale over the counter. This offers many more people access to a new nonprescription option for preventing pregnancy.

Opill may be available early in 2024, although the exact date and cost are not yet known. Here’s what anyone interested — adults, parents, and teens — should know.

What is in Opill and how does it work?

Opill is a progestin-only form of birth control. That means it uses a single hormone called progestin (or norgestrel) to prevent pregnancy. It works by

• affecting ovulation so that the ovaries do not release an egg every month
• thickening cervical mucus, which blocks sperm from reaching an egg
• changing the uterine lining in ways that keep a fertilized egg from implanting.

How effective is Opill at preventing pregnancy?

It depends on how consistent you are about taking Opill:

• Perfect use means taking the pill every single day at the same time. With perfect use, Opill is 98% effective. That means that if 100 people take the medication perfectly, two or fewer people would become pregnant. Taking a pill perfectly can be difficult, though.
• Typical use averages how well a method works to prevent pregnancy when real people use it in real life. It considers that people sometimes use the pill inconsistently, like forgetting a dose or not taking it at the same time every day. With typical use, Opill is 91% effective. This means that if 100 people use Opill, but don’t take it perfectly, at least nine could become pregnant in a year.

It's also important to know that some medications make Opill less effective at preventing pregnancy. These include medicines used to treat migraines and seizures. Even though this birth control pill will be available over the counter, you should ask your health care provider if any medicines you take could make it less effective.

How do you take Opill?

• Take it once a day at the same time each day until you finish the entire pack.
• Sticking to a consistent time of day, every day, is crucial. Timing matters with progestin-only pills like Opill because this medication works by raising progestin levels. However, progestin only stays elevated for 24 hours after you take each pill. After that, the progestin level will return to normal.
• After you complete a 28-day pack, you should immediately start a new pack of pills the next day.

What happens if you forget to take a dose at the specific time or miss a dose?

• If you take the pill more than three hours late it will not be as effective at preventing pregnancy.
• Take the missed pill as soon you remember.
• You will need to use a backup birth control method such as condoms every time you have sex for the next 48 hours.

Is Opill safe for teenagers?

Opill is generally safe for most people who could get pregnant, including teenagers. There’s no evidence to suggest that safety or side effects are different in teenagers compared with adults.

Research done by the manufacturer has established the safety of Opill in people as young as 15 years old. It will be available without an age restriction.

When teens use birth control, what is the best choice for them?

There isn't a one-size-fits-all birth control method for all teenagers. The best method is the one a teen personally prefers and is committed to using consistently.

For teens who struggle with taking medication at the same time every day –– or anyone else who does –– Opill may not be the right choice. Fortunately, there are many options for preventing pregnancy, catering to individual preferences and goals.

What side effects are common with Opill?

Progestin-only pills are usually associated with mild side effects. The most common side effects are:

• unexpected vaginal bleeding or spotting
• acne
• headache
• gastrointestinal symptoms such as nausea, abdominal pain, and bloating
• change in appetite.

Opill does not cause problems with getting pregnant in the future, or cause cancer. Unlike birth control pills that combine the hormones estrogen and progestin, Opill will not increase the risk of a developing a blood clot.

Will Opill cause any mood changes?

Research looking at possible effects of progestin-only pills on mood is limited, so this is unclear. We do know that most people who take hormonal birth control methods do not experience negative mood changes.

Fortunately, there are many different types of effective birth control. If one method causes you unwanted side effects, talk to your health care provider. Together, you can figure out if another type of birth control may work better for you.

Can it be used as emergency birth control?

No, it should not be used as emergency birth control.

What should you know about STIs?

This type of birth control does not protect you from sexually transmitted infections (STIs) such as syphilis, gonorrhea, or chlamydia.

You can reduce the chance of getting STIs by correctly using condoms each time you have sex. There are different types of condoms: one made for penises and one made for vaginas.

Vaccines help protect against some STIs such as hepatitis B and human papillomavirus (HPV). A medicine called PrEP can help prevent HIV. Ask your medical team for more information about the right choices for you.

When will Opill be available and what will it cost?

The timeline for availability and the cost of medication is determined by the manufacturer. At time of FDA approval, it was expected to hit shelves in early 2024. No updates have been released for the exact date or estimated cost of the medication.

Headaches are very common in children and teens. In fact, more than half will suffer from headaches at some point, and by 18 years the majority of adolescents have had them. And while most headaches are part of a viral illness, some are migraines. In fact, recurring migraines affect as many as one in 10 children and teens overall.  

What should you know — and do — if you think your child or teen may be having migraines?

How early do migraines start to occur?

We don’t tend to think about migraines in children, but by age 10, one in 20 children has had a migraine. And migraines sometimes occur even earlier.

Before puberty, boys and girls are equally likely to have them. After puberty, migraines are more common in girls.

Which migraine symptoms are most common in children?

Migraines are often one-sided in adults. In children they are more likely to be felt on both sides of the head, either in both temples or both sides of the forehead.

While it’s not always easy to tell a migraine from another kind of headache, children

• often report throbbing pain
• may experience nausea and sensitivity to light and noise.

The flashing lights and other vision changes people often see as a migraine begins are less common in children. However, parents may notice that their child is more tired, irritable, or pale before a migraine begins — and takes a while to get back to normal after it ends.

What causes migraines in children?

We don’t know exactly what causes migraines. We used to think it had to do with blood flow to the brain, but that does not seem to be the case. It appears that migraines are caused by the nerves being more sensitive, and more reactive to stimulation. That stimulation could be stress, fatigue, hunger, almost anything.

Migraines run in families. In fact, most migraine sufferers have someone in the family who gets migraines too.

Can migraines be prevented?

The best way to prevent migraines is to identify and avoid triggers. The triggers are different in each person, which is why it’s a good idea to keep a headache diary.

When your child gets a headache, write down what was happening before the headache, how badly it hurt and where, what helped, and anything else about it you can think of. This helps you and your doctor see patterns that can help you understand your child’s particular triggers.

It’s a good idea to make sure your child gets enough sleep, eats regularly and healthfully, drinks water regularly, gets exercise, and manages stress. Doing this not only helps prevent migraines, but is also good for overall health!

How can you help your child ease a migraine?

When a migraine strikes, sometimes just lying down in a dark, quiet room with a cool cloth on the forehead is enough. If it’s not, ibuprofen or acetaminophen can be helpful; your doctor can tell you the best dose for your child.

It’s important not to give your child these medications more than about 14 days a month, as giving them more often can lead to rebound headaches and make everything worse!

Are there prescription medicines that can help children with migraines?

If those approaches aren’t enough, a class of medications called triptans can be helpful in stopping migraines in children ages 6 and up.

If a child experiences frequent or severe migraines, leading to missed days of school or otherwise interfering with life, doctors often use medications to prevent migraines. There are a number of different kinds, and your doctor can advise you on what would be best for your child.

Some girls get migraines around the time of their period. If that happens frequently, sometimes taking a prevention medicine around the time of menses each month can be helpful.

When to contact your doctor

If you think your child might be having migraines, you should call and make an appointment. Bring the headache diary with you. Your doctor will ask a bunch of questions, do a physical examination, and make a diagnosis. Together you can come up with the best plan for your child.

You should always call your doctor, or go to an emergency room, if your child has a severe headache, a stiff neck, trouble with coordination or movement, is abnormally sleepy, or isn’t talking or behaving normally.

The American Academy of Pediatrics has additional useful information about migraines, and how to treat and prevent them, on their website.
