Other medicines and Cyclogest

of pain) as they may decrease the effectiveness of progesterone.

Further Information:
Premenstrual Syndrome
Many women suffer from a condition called premenstrual syndrome or PMS. This
is commonly known as PMT (premenstrual tension) because of the anxiety and
bad temper often associated with it. However, there are many other symptoms
that occur with PMS including depression, bloating and breast tenderness. It is not
just your symptoms that decide whether you have PMS but the time at which they
are at their worst.
PMS is characterised by the symptoms that occur during the days leading up to
your period and are then completely relieved by menstruation. The cause of PMS
is not completely understood but it is believed to be related to the hormonal
changes that occur during the monthly cycle. Many women obtain relief from their
symptoms when their hormonal balance is altered with a medicine prescribed by
their doctor.
Further information about PMS can be obtained from:

Post-Natal Depression
Many mothers experience short-term periods of mild depression following the
birth of their baby. This is a common condition, usually occurring three or four
days after delivery, affecting at least half of all new mothers who may feel tearful,
overwhelmed and irritable during this time. Support, reassurance and rest can
help these feelings to pass within a few days.
However, if the anxiety does not improve, the mother may be developing postnatal
depression. Up to 15 per cent of new mothers develop more severe symptoms
within 12 months of their child’s birth. Postnatal depression (PND) is
characterised by marked low mood for a more prolonged period of time.
Though it may take several weeks or months until a full recovery is reached, PND
is a treatable condition from which the mother will get better.
Speak to your midwife, health visitor or doctor if you have any further questions.
