The NHS has issued an urgent patient safety alert concerning a widely prescribed medication. Individuals taking sodium valproate are being advised to contact their doctor or specialist nurse without delay if they fall into specific groups.
Critical Guidance for Patients on Common Treatment
This prescription drug, known under brand names including Epilim, Dyzantil, Episenta, and Epival, is a long-established treatment for epilepsy and bipolar disorder. However, updated NHS guidance highlights significant risks that require immediate medical consultation for certain patients.
The medicine is strictly prescription-only. For patients under 55, it must be prescribed by a specialist, who also requires a second specialist opinion confirming no alternative treatment is suitable. It is available in various forms, such as capsules, tablets, swallowable liquid, or granules to mix with food or drink.
Pregnancy Prevention Programme and Urgent Action
The most critical warning is directed at women. Sodium valproate is not recommended in pregnancy due to a high risk of causing birth defects and developmental or behavioural issues in children.
The NHS states clearly: "If you think you might be pregnant and you're taking sodium valproate, contact your doctor or nurse urgently." Women of childbearing potential prescribed this medication should be enrolled in Prevent, the valproate pregnancy prevention programme.
It is vital that patients do not stop taking their medication abruptly, as this could worsen epilepsy or bipolar symptoms. A doctor must oversee any changes. For pregnant women with migraine, an alternative treatment should be offered.
Fertility Concerns for Men and Women
The advisory also extends to men planning a family. Men who could father a child are urged to discuss their treatment with a doctor. Effective contraception is required while taking the drug and for at least three months after stopping.
For men aiming to start a family within a year, a conversation about treatment options is essential. Sodium valproate can reduce fertility in both sexes and has been linked to infertility in men, though this may be reversible upon stopping the medication.
In women, the drug can disrupt the menstrual cycle, causing missed periods, and has been rarely associated with polycystic ovary syndrome (PCOS).
The overarching message from the NHS is unambiguous: Do not stop or alter your medication without first speaking to your doctor. Anyone with concerns about how sodium valproate may affect their fertility or pregnancy plans should seek professional medical advice immediately.
