How Troynuron SR works
Methylcobalamin replaces a B vitamin your body needs to make red blood cells, to keep nerves healthy and to release energy from food.
How to take Troynuron SR

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
Missed dose and overdose
If you miss a dose
Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.
If you take too much
An overdose of this medicine is unlikely to cause serious harm, because the body passes surplus B vitamins out in the urine. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.

- Nausea
- Stomach upset
- Harmless bright yellow urine
- Loose motions
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Warnings and precautions
Tingling, numbness or burning in the hands and feet should be assessed by a doctor rather than self-treated — a supplement does not address the cause. Folic acid can mask a vitamin B12 deficiency while nerve damage continues, so B12 should be checked before taking folic acid long term. Bright yellow urine after a B-complex dose is expected and harmless.
Do not take Troynuron SR if
Not for anyone with a known allergy to this medicine or to any ingredient in the pack.
Interactions with other medicines
Long-term metformin, acid-reducing medicines and some anti-epileptics lower B12 or folate levels. Tell your doctor if you take levodopa, as vitamin B6 can reduce its effect.
How to store Troynuron SR
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
Expert advice for Troynuron SR
A supplement corrects a deficiency; it is not a general energy tonic. If you are on it for nerve symptoms, keep your review appointment so the underlying cause is looked for.
