Buy Gedarel contraceptive pills online

Gedarel is a combined contraceptive pill containing synthetic versions of the natural female sex hormones progestogen and oestrogen: desogestrel and ethinylestradiol. These hormones prevent pregnancy by stopping the ovary from releasing an egg each month, thickening the fluid at the neck of the womb and thinning the lining of the womb. When used correctly, the combined contraceptive pill can be 99% effective at preventing pregnancy.


How does Gedarel work

Gedarel contains two synthetic female hormones to help protect against pregnancy: desogestrel and ethinylestradiol. These active substances work as a contraceptive by preventing your ovaries from releasing an egg every month. These hormones also work by thickening the mucus in the cervix (the neck of the womb) so it’s harder for sperm to reach an egg, and thinning the lining of the womb so there’s less chance of a fertilised egg being able to implant itself into the womb and start growing.



Gedarel comes in strips of 21 tablets, each marked with a corresponding day of the week to make it easier for you to keep track. You should take the pill once a day, every day, with or without food. Make sure you swallow the pill whole with water if necessary - do not try to chew or break the tablet. You should make sure to take your pill at around the same time every day so it works properly. Once you have finished the strip of 21 tablets, you will then need to take a 7-day break where you take no tablets at all. This will cause a withdrawal bleed similar to a period. You will need to start the next strip of tablets once the 7-day break has finished, even if you’re still bleeding.


What should I do if I miss a pill? 

If you’re less than 12 hours late in taking a pill, your protection from pregnancy won’t be reduced. If you’re more than 12 hours late, you will have to use a barrier method of contraception. The more pills you miss, the greater your risk of becoming pregnant.


More than one tablet forgotten: 

Contact your doctor or Chemist4U pharmacist.


One pill forgotten in week 1: 

Take the forgotten pill as soon as you remember, even if that means taking two in one day. Continue taking your pills at the usual time and use barrier contraception for the next 7 days. If you have had sex in the week before forgetting your pill, you could be pregnant - contact your doctor if this is the case.


One pill forgotten in week 2: 

Take the forgotten pill as soon as you remember, even if that means taking two in one day. Continue taking your pills at the usual time; you are still protected from pregnancy and don’t need to use extra contraception.


One tablet forgotten in week 3:

Either take the forgotten pill as soon as you remember, even if that means taking two in one day. Continue taking your pills at the usual time, but instead of taking the 7-day break at the end of the strip, skip this break and go straight to your next strip. Or you can stop the strip immediately and begin the 7-day break, which will include the day you forgot your pill. After that, start your next strip as normal. If you are sick or have severe diarrhoea within 3-4 hours of taking Gedarel, your body may not have absorbed the active substances in the pill. If you can’t manage to take a spare pill within 12 hours of vomiting or having severe diarrhoea, you should refer to the patient information leaflet and follow the instructions on what to do in the event of a missed pill.


Starting Gedarel

If you are starting Gedarel for the first time and you haven’t taken any other hormonal contraceptives in the past month, you should take the first pill on the first day of your period. This way, you will be protected from pregnancy straight away. If you wish to start Gedarel on a different day, you will need to use barrier contraception for the first 7 days of pill taking. If you are changing from a different method of contraception, refer to the patient information leaflet for specific advice on how to start taking Gedarel.


Side effects

Like all medicines, there is a possibility that you may experience side effects when taking Gedarel. These should usually be mild, and not everyone will experience them. Seek medical attention immediately if you experience any signs of severe side effects such as an allergic reaction or a blood clot. For information on severe side effects and their symptoms, refer to the patient information leaflet. Common side effects include: 

  • Irregular bleeding

  • Depression or altered mood

  • Nervousness 

  • Headache or dizziness

  • Nausea or abdominal pain

  • Acne 

  • Tender breasts or breast pain

  • Absence of menstruation, painful menstruation or premenstrual syndrome

  • Weight gain

For information about uncommon and rare side effects, refer to the patient information leaflet. If you experience any side effects, including any not included in the patient information leaflet, you can report them using the MHRA Yellow Card Scheme


Blood clots

Using a combined contraceptive pill like Gedarel can increase your risk of developing a blood clot. Whilst still rare, the risk is highest during the first year of taking the pill, and you should be aware of the symptoms. Seek emergency medical attention if you experience any of the following symptoms: 

  • Throbbing or cramping pain, swelling, redness and warmth in your leg or arm

  • Sudden breathlessness, sharp chest pain and a cough or coughing up blood 

For further information on the link between the combined contraceptive pill and blood clots, as well as more symptoms to look out for, refer to the patient information leaflet. 


Breast cancer

Breast cancer has been found slightly more often in women who take a contraceptive pill compared to women who don’t. Once you stop taking the pill, the risk gradually decreases and 10 years after stopping the pill the risk will be the same as someone who has never taken a contraceptive pill. Breast cancer is still rare for anyone under the age of 40, even in women who take the pill.

Frequently Asked Questions

Can the pill be used to treat acne?

Combined contraceptive pills are not specific treatments for acne.

However, some doctors will prescribe a combined contraceptive pill to women who suffer from hormonal acne, as there does seem to be a beneficial effect.

This is only the case with combined contraceptive pills, not progestogen-only mini-pills.

It can take around 2-3 months of taking the pill before you may notice any effect on your acne.

You do need a prescription for this medication in the UK.
