Long-acting reversible contraceptives (LARCs), such as hormonal implants and intrauterine devices (IUDs), are among the most effective birth control methods available. Implants can prevent pregnancy for up to 3 years, while IUDs offer protection for 3 to 10 years depending on the type. Both are over 99% effective and require no daily action.

If you're weighing your contraceptive options—or experiencing symptoms related to hormones, menstruation, or reproductive health—it's worth understanding your body before making decisions. A free, instant, online symptom check can help you identify possible causes of what you're experiencing and guide your next steps, whether that means talking to a doctor, exploring treatment, or choosing the right contraception for your needs.

Explanation

Long-acting reversible contraceptives (LARCs) are highly effective methods to prevent pregnancy for a long time. These methods include implants and intrauterine devices (IUDs).

Implants: These are small rods placed under the skin of the arm. They release hormones that stop pregnancy and can work for up to 3 to 5 years.
IUDs: These are small devices placed in the uterus. They can be hormonal or non-hormonal. Hormonal IUDs release hormones and can last 3 to 7 years, while non-hormonal ones, made of copper, can last up to 10 years.

These methods are very effective because they do not require you to remember to take a pill every day. Once they are in place, they work without any action needed from you. LARCs are a good choice for people who want long-term birth control without daily attention. If you're experiencing any unusual symptoms or side effects, you can check your symptoms to better understand what might be happening with your body.
