01

Different methods do different jobs

Contraception reduces the chance of pregnancy. Options include condoms and other barrier methods, pills, injections, patches, rings, implants and intrauterine devices. Effectiveness, side effects, privacy, cost and medical suitability differ.

02

Pregnancy prevention is not STI prevention

Most contraceptive methods do not protect against sexually transmitted infections. Condoms can reduce the risk of many STIs when used correctly and consistently, although they do not remove all risk.

03

Typical use matters

A method can work differently in everyday life than under perfect-use conditions. Missing pills, incorrect condom use or late injections can reduce protection. Long-acting reversible methods require less ongoing action, but need a trained clinician.

04

Choosing safely

A qualified clinician can help compare options based on health history, medicines, migraine history, smoking, blood-pressure risk and personal priorities. Do not use another person’s prescription.

Keep these three points

What to remember

  1. No single method is best for everyone.
  2. Condoms help reduce STI risk; most other methods do not.
  3. Discuss medical suitability with a qualified clinician.
