Neurology
Neurology medicines are chosen for a specific diagnosis and often need gradual adjustment and ongoing monitoring. A medicine used for more than one condition can have different benefits and risks in each setting.

Key points
- Seizure, Parkinson’s, migraine-prevention and neuropathic-pain medicines are not interchangeable even when one ingredient has several uses.
- Do not stop seizure or Parkinson’s medicine suddenly; abrupt withdrawal can cause serious deterioration.
- A prolonged or repeated seizure, new weakness or speech difficulty, or a sudden severe headache needs emergency assessment.
Select a listed product and pack to order online. Supply depends on stock and destination rules; ask your doctor or pharmacist whether it suits you.
How the medicine groups differ
- Antiseizure medicine: valproic acid may control selected seizure types and has other specialist uses, but carries major pregnancy-related risks.
- Parkinson’s medicines: levodopa is combined with carbidopa to improve delivery of levodopa to the brain and reduce its breakdown outside the brain.
- Migraine prevention and neuropathic pain: propranolol may be used to prevent migraine, while duloxetine may be used for selected neuropathic pain conditions.
What these medicines are used for
Linked conditions include epilepsy, Parkinson’s disease, migraine prophylaxis and bipolar disorder. Several ingredients here are used across more than one of those, which is why the same name turns up in different places. Prophylaxis means preventing attacks rather than treating one already under way.
Important safety checks
Pregnancy planning is critical with valproate: it is restricted because exposure during pregnancy can cause congenital malformations and developmental harm. Kidney or liver function, mood changes, falls, driving safety and interactions may also need review, depending on the medicine.
When to seek urgent care
Call emergency services for a first, prolonged or repeated seizure without recovery; new facial droop, limb weakness or speech difficulty; a sudden severe headache; severe confusion; or thoughts of suicide or self-harm.
