Sex, pregnancy & mood stabilisers

Mood stabilisers could possibly affect sexual activity, though this is rare. It is also worth noting potential risks of taking mood stabilisers whilst pregnant or breastfeeding.

Sex

Drugs can affect desire (libido/sex drive), arousal (erection), and your ability to have an orgasm. Mood stabilisers have not been reported to have a major adverse effect on these three stages. However, if this does happen, you should discuss it with your doctor, as a change in dose may help minimise the problem.

If you are considering trying for a baby you are well advised to contact your doctor and discuss your options.

Pregnancy

There is no evidence to suggest that pregnancy itself increases the risk of relapse in patients with manic depression. However, the risk of relapse after giving birth is hugely increased: up to 8 times.
Taking lithium during pregnancy has a well known risk of heart problems in the foetus. The time when the foetus is at most risk is 2-6 weeks after conception; before the majority of women will know that they are pregnant. Lithium should be avoided in pregnancy if possible.

Both carbamazepine and valproate taken during pregnancy have a clear link with increased risk of foetal abnormalities, particularly spina bifida. Both drugs should be avoided if possible. There is not enough research relating to lamotrigine to recommend its use.

Olanzapine is not associated with foetal deformities but there is a higher risk of getting diabetes while you are pregnant.
Pregnancy & mental illness

Breastfeeding

All mood stabilisers are excreted in breast milk and recommendations are that they are avoided as far as possible. Your options during this period should be discussed with your doctor or psychiatrist.
