Because fertilisation and the early development of a baby are controlled by delicately balanced processes in the body, any additional chemicals can upset this balance.
Any medicines, that could be potentially hazardous to fertility and the development of the unborn baby need to be stopped. If you are on long-term medication this may need to be reduced or stopped before you become pregnant, or it may need to be changed to medication that is safer for use in pregnancy.
Never stop taking long-term medication without seeking medical advice. Other medicines, such as those used for asthma, must be continued so it’s important to discuss any medication you are taking with your doctor.
You should always tell your doctor that you are trying for a baby when he is prescribing medicines and ask the chemist whether any over-the-counter medicine you are buying is safe for use in pregnancy.
Some medicines are not safe for use in pregnancy, these include some antibiotics, cold remedies, antihistamines, general multivitamins and non-steroidal anti-inflammatory drugs. So when you are trying to conceive these should be avoided.
Even caffeine, taken in excess, can affect your chances of conception. If you are trying to conceive you should always seek advice from a health professional before taking over-the-counter medications, natural remedies and supplements.
