ellaOne Side Effects

ellaOne is a form of emergency contraception which can be taken up to five days after having unprotected sex. It is considered a highly effective way of preventing pregnancy and is very safe for women to use in case of a problem with the chosen contraceptive method.

Are there any side effects?

As with all medications, taking ellaOne as an emergency contraceptive can sometimes cause side effects. Medications affect different people in different ways, and bodily reactions - especially hormonal changes - can change from one person to the next.

None of the side effects should last longer than a few days, but if they persist, it is worth consulting a doctor or pharmacist to see what your options are.

It is possible that you will experience a mild headache and some dizziness after taking ellaOne. Migraines are less common but may still occur. You may also notice that your mood is temporarily affected by this medication.

What causes the side effects?

Because ellaOne contains a high level of artificial hormones, it can alter the body's natural cycle. Hormones can affect different women in very different ways and some people may not experience any side effects at all. It is important to remember that ellaOne should not be taken on a regular basis and never twice during the same menstrual cycle.

What should I do if I experience any ellaOne side effects?

If you take this emergency contraception pill and experience any of the side effects, you should not worry. They should only last a couple of days, and then go away. If they do persist and cause you discomfort, then consult a doctor, family planning clinic or pharmacist. They can provide advice on what to do, make a note of your reactions and suggest the next step for you.
