PREGA HY-M CAP
METHYLCOBALAMINE + PREGABALIN 75MG
PREGA HY-M CAP is a capsule combining pregabalin 75 mg with methylcobalamin, for neuropathic pain. It is used in diabetic peripheral neuropathy, post-herpetic neuralgia, sciatica, fibromyalgia and other nerve-related pain that does not respond to conventional analgesics.
01
Benefits
- Pregabalin binds to calcium channel subunits in the central nervous system, reducing the abnormal nerve signalling that causes burning and shooting pain.
- Neuropathic pain responds poorly to ordinary analgesics; pregabalin acts on the mechanism generating the pain instead.
- Methylcobalamin is the active coenzyme form of vitamin B12, involved directly in myelin formation and nerve repair.
- Pregabalin also improves the disturbed sleep and anxiety that commonly accompany chronic nerve pain.
- Effect is usually apparent within the first week, faster than with several alternatives.

03
Precautions
- Pregabalin is a controlled drug in many countries and carries a real risk of misuse and dependence, particularly in patients with a history of substance misuse. Prescribe and dispense accordingly.
- Never stop abruptly after regular use — taper under supervision to avoid withdrawal symptoms including anxiety, insomnia, nausea and sweating.
- Pregabalin combined with opioids causes profound sedation and respiratory depression and has caused deaths. Avoid the combination or use with close monitoring.
- Causes marked drowsiness and dizziness, particularly when starting or increasing the dose. The patient must not drive or operate machinery until the effect is known.
- Dose reduction is required in renal impairment, as pregabalin is renally cleared — this is frequently overlooked in diabetic patients with nephropathy.
- Use with particular caution in the elderly, who are more susceptible to sedation, confusion and falls.
- Avoid alcohol entirely, and use with caution in heart failure, where fluid retention can worsen it.
- Contraindicated in pregnancy unless clearly necessary; use in breastfeeding only on medical advice.
