IUDs vs. Birth Control Pills: What to Consider


Your Birth Control Options
If you want to avoid pregnancy, you may be considering an IUD or the birth control pill from among the many options. Each method has pros and cons, side effects, and risks.

Copper vs. Hormonal IUDs
IUDs come in two forms. Copper IUDs use copper to prevent pregnancy, while hormonal IUDs release hormones to achieve the same goal. Both are highly effective but have different side effects and benefits.

Concerns with IUDs
IUD insertion can be uncomfortable, and some users experience side effects like cramping and irregular bleeding. IUDs carry a small risk of pelvic inflammatory disease. IUDs raise your risk of ectopic pregnancy, although that's rare.

Combined vs. Progestin-Only Pills
Birth control pills come in two main types: combined (estrogen and progestin) and progestin-only. Each type has different benefits and side effects.

Concerns With Birth Control Pills
Common side effects of birth control pills include nausea, weight gain, and mood changes. Combination pills could raise your chances of heart attacks, stroke, and blood clots. You're also at higher risk of cervical and breast cancer. You might be at higher risk of ectopic pregnancy with the minipill, but it's rare.

Using Multiple Methods
You can use more than one birth control method for added protection. For example, combining condoms with birth control pills can reduce the risk of pregnancy and STIs.

Cost Considerations: IUDs vs. Pills
IUDs can be more expensive up-front but are cost-effective over time, while pills require ongoing monthly expenses.
