About this medication

  • ella is an emergency contraceptive that helps prevent pregnancy after unprotected sex or if your usual birth control failed.
  • It works best the sooner you take it after sex, and it must be taken within 5 days.
  • ella is only for occasional, emergency use. It is not meant to replace your regular birth control method.

Reduces pregnancy risk after unprotected intercourse or contraceptive failure.

How to use it

  • Swallow the tablet whole with a glass of water.
  • You can take ella with or without food.
  • Take it as soon as possible after unprotected sex, and no later than 5 days afterward. The sooner you take it, the better it works.
  • If you throw up within a few hours of taking ella, contact your healthcare professional, since you may need to take another tablet.

If you miss a dose

  • This is a one-time dose taken after unprotected sex, so there is no regular dosing schedule to miss.
  • If you are not sure whether you took ella correctly, or you need it again after another act of unprotected sex, talk to your healthcare professional.

Take as soon as possible within five days. Vomiting within three hours may require another dose; contact the Care365 clinical team.

Pregnancy and breastfeeding

  • Do not take ella if you are already pregnant or think you might be pregnant, since it will not end a pregnancy and its safety in pregnancy is not established.
  • Do not breastfeed for one week after taking ella. Pump and throw away your milk during this week to keep up your milk supply, then resume breastfeeding as normal.

The Canadian source advises a breastfeeding interruption; discuss current product guidance before use.

Before you use it

  • Tell your healthcare professional if your period is late or you have signs of pregnancy, such as breast tenderness or morning sickness, since you may already be pregnant.
  • Tell your healthcare professional if you have severe liver disease.
  • Tell your healthcare professional if you are lactose intolerant, since this medicine contains lactose.
  • Tell your healthcare professional if you are breastfeeding.
  • Tell your healthcare professional about any allergies you have.

Important warnings

  • ella does not protect you from sexually transmitted infections, including HIV. Only condoms help protect against these infections.
  • ella will not end a pregnancy that has already started. If you think you might already be pregnant, talk to your healthcare professional.
  • ella only protects you from the one act of unprotected sex it was taken for. You can get pregnant again right away, so use a reliable barrier method, such as condoms, for the rest of your cycle.
  • Do not take ella more than once in the same menstrual cycle.

Not for an established pregnancy or ongoing contraceptive protection.

  • Headache, dizziness, or feeling tired can happen.
  • Nausea or stomach pain can happen.
  • Menstrual cramps, back pain, or breast tenderness can happen.
  • Your next period may come a few days earlier or later than usual.

When to get help

When to get emergency help

  • Get emergency help for signs of a severe allergic reaction: hives, a skin rash, swelling of the face, lips, tongue, or throat, or trouble breathing or swallowing.

When to contact a healthcare professional

  • Contact your healthcare professional if your period is more than 7 days late, or is unusually light or heavy.
  • Contact your healthcare professional if you have stomach pain, breast tenderness, nausea, or vomiting after your expected period, since these can be signs of pregnancy.
  • Contact your healthcare professional if you think you might be pregnant, so you can be tested and get the right care.
  • Contact your healthcare professional if you find yourself needing emergency contraception often, so you can discuss a regular birth control method that works for you.

Severe abdominal pain or a period more than a week late requires pregnancy assessment.

Other medicines and products

  • Tell the Care365 care team about all medicines you take, including ones for seizures, tuberculosis, HIV, fungal infections, and heartburn, since several of these can make ella less effective.
  • Tell the Care365 care team if you take St. John's Wort, an herbal product, since it can also make ella less effective.
  • If you use hormonal birth control, such as the pill, patch, or ring, wait several days after taking ella before starting or restarting it, and use a barrier method like condoms until your next period.
  • Do not take ella together with another emergency contraceptive that contains levonorgestrel.

Enzyme inducers and progestin contraceptives can affect effectiveness; obtain a specific contraception restart and backup plan.

Missed doses, storage and accidental exposure

  • Store at room temperature, in the original sealed package, away from light and moisture.
  • Keep out of reach and sight of children.

Follow your own product’s missed-dose instructions. If you are unsure, ask the Care365 clinical team before taking an extra dose. Contraceptives, injections and modified-release medicines may need a specific plan.

Keep the original packaging and follow its storage, expiry and disposal instructions. Keep medicines away from children and pets. Ask about refrigeration, after-opening limits and safe sharps disposal when relevant.

For suspected overdose or accidental swallowing, contact poison control or urgent medical care promptly. Call emergency services for breathing difficulty, collapse or a seizure.

Key points to remember

  • ella works best the sooner you take it, so do not wait if you think you need it.
  • Talk to your healthcare professional about choosing a regular method of birth control that works for you, so you have reliable protection going forward.
  • This medicine can cause dizziness, drowsiness, or blurred vision. Do not drive or use machinery if you feel this way.
  • Keep this medicine out of reach of children, since it is not intended for anyone other than the person it was prescribed or purchased for.

These practical points come from the Pharmasist patient handout for the same product monograph cited by this guide.
