What Makes Triadene Stop Working?

Combined Contraceptive Pill »

The pill is one of the most effective methods of contraception if it is used correctly. However, incorrect usage will lead to a higher risk of pregnancy because if you miss a pill, the levels of hormones are disrupted and it cannot maintain its effects on the menstrual cycle. Therefore, you are more at risk at falling pregnant if you are late in taking a pill or miss a pill altogether.

Medications can also affect the pill and stop it from working properly. Most of the medications used to treat epilepsy will render the pill ineffective. Antibiotics and an anti-fungal medicine called griseofulvin will also have a similar effect. There is a chance that phenylbutazone, which is an anti-inflammatory medication, can stop the pill from working properly and some sedatives can also reduce the pills effectiveness. It is not always prescribed medications that have this effect but some herbal remedies such as St Johns Wort, can stop the pill working. Therefore, you need to report any type of medication that you are using to your doctor so that they can make sure the effectiveness of your pill will not be affected and that your pill will not interfere with other medications. Often, they will advise you to use additional contraception during your treatment and for the next seven days if you are using the medication for the short term but to consider changing your method of contraception if you are using the medication for a long period of time.

Also, if you are sick or have severe diarrhoea, the pill may not work properly. It may not have had enough time to absorb into your blood stream before you were ill. Therefore, you may not be protected from pregnancy.  If you have stopped being ill within 12 hours of taking the pill, take another pill from a spare packet and treat it as a lost pill. However, if it is more than 12 hours then you need to follow the instructions for a missed pill.
