How Megabid 50 works

This medicine combines 2 active ingredients: Methylcobalamin and Pregabalin. Methylcobalamin replaces a B vitamin your body needs to make red blood cells, to keep nerves healthy and to release energy from food. Pregabalin calms the over-active nerve signals that cause burning, shooting and tingling pain.

How to take Megabid 50

Use this medicine as your doctor has directed. Follow the dose and the duration written on your prescription.

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. It can cause deep drowsiness, confusion, unsteadiness and slowed breathing, especially with an opioid or alcohol. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.

Side effects of Megabid 50

Most side effects of Megabid are mild and settle as the body adjusts. Reported side effects include:

• Nausea
• Stomach upset

• Loose motions
• Drowsiness
• Dizziness
• Swelling of the ankles and feet
• Weight gain
• Blurred vision
• Unsteadiness

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.

Safety advice for Megabid 50

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. This medicine causes drowsiness and unsteadiness, particularly when you start it or the dose goes up. Do not drive or operate machinery until you know how it affects you. Never stop it suddenly. Stopping abruptly can cause anxiety, sleeplessness, sweating and, in people taking it for epilepsy, fits. Your doctor will taper it. Tell your doctor about any change in mood or any thoughts of harming yourself. The dose is usually built up slowly from a low starting point — follow the schedule your doctor gave you rather than jumping to the full dose. Pregabalin comes under Schedule H1 from 16 November 2026 and will then need a prescription and a pharmacy register entry.

Do not take Megabid 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. Opioid painkillers, alcohol, sleeping tablets and antihistamines all add to the drowsiness, and the combination with opioids can dangerously slow breathing. Antacids reduce the absorption of gabapentin — separate them by a couple of hours.

How to store Megabid 50

Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.

Expert advice for Megabid 50

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. Take the larger part of the dose at night if drowsiness is a problem. Rise slowly from sitting or lying, especially in the first weeks. Keep your review appointment so the dose can be adjusted to the lowest that controls your pain.
