Pregabalin

Pregabalin is a gabapentinoid — neuropathic pain agent and anticonvulsant (prescription-only) medicine available in Bangladesh under many brand names. Below are its uses, dosage, side effects and precautions — and all brands with their current prices.

Pregabalin is prescribed for:

• Neuropathic pain — diabetic peripheral neuropathy, post-herpetic neuralgia (pain after shingles), nerve pain from spinal cord injury, sciatica-type nerve pain when a specialist advises
• Fibromyalgia — widespread body pain with fatigue and sleep problems
• Epilepsy — as add-on treatment for partial (focal) seizures
• Generalised anxiety disorder — under psychiatric supervision

It must be used only for a doctor-confirmed diagnosis. It does not work for ordinary headaches, muscle pain or arthritis, and self-medication risks dependence.

Pregabalin dosing is always individualised by the doctor. A common adult pattern for nerve pain:

• Start low, often 75 mg once or twice daily (sometimes 50–75 mg at night)
• Increase gradually every few days as tolerated
• Usual maintenance 150–300 mg per day in two divided doses; maximum 600 mg per day in selected cases

It may be taken with or without food, at the same times each day. Kidney impairment requires a reduced dose. Never increase the dose yourself, never share it, and never stop suddenly — the dose must be tapered down over at least a week under medical guidance.

Common side effects of Pregabalin, especially in the first weeks:

• Dizziness and sleepiness — the most frequent; often settle with time
• Unsteadiness, blurred vision, poor concentration
• Weight gain and increased appetite
• Swelling of hands, ankles or feet
• Dry mouth, constipation
• Mood changes; rarely, depressed mood or suicidal thoughts — report these immediately

Serious but uncommon: severe allergic swelling of face or tongue, breathing difficulty (especially combined with opioids or other sedatives), and dependence with withdrawal symptoms (insomnia, anxiety, sweating, seizures) if stopped abruptly.

Essential precautions with Pregabalin:

• Take it only on a doctor's prescription, for the diagnosed condition — pregabalin is widely misused in Bangladesh and causes real dependence
• Never stop abruptly; taper over at least a week as your doctor directs
• Avoid driving, riding motorbikes or operating machinery until you know how drowsy it makes you
• Do not drink alcohol and do not combine with sleeping pills or opioid painkillers without medical advice — breathing can be dangerously suppressed
• Tell your doctor about kidney disease, heart failure, breathing problems, mood disorders or any history of substance misuse
• Watch weight and ankle swelling; diabetics should monitor glucose and foot skin
• Keep it securely away from others — never share

Important interactions of Pregabalin:

• Opioid painkillers (tramadol, morphine, codeine) — combined sedation and dangerous breathing suppression; use together only under close medical supervision
• Benzodiazepines and sleeping pills (clonazepam, diazepam, zolpidem) — additive drowsiness and respiratory depression
• Alcohol — markedly increases sedation and accident risk; avoid completely
• Antihistamines and other sedating medicines — added drowsiness
• Pioglitazone and similar diabetes medicines — increased fluid retention and weight gain
• ACE inhibitors — possible higher risk of facial swelling (angioedema)

Pregabalin has few interactions through liver enzymes, but its sedative combinations are the real danger — tell your doctor everything you take.

Do not take Pregabalin if you have:

• Known allergy to pregabalin or any ingredient of the product

Use it only with special caution and specialist advice if you have:

• Significant kidney impairment (dose must be reduced)
• Severe breathing problems or you take opioids/sedatives
• A history of drug or alcohol misuse — dependence risk is higher
• Severe heart failure
• Rare hereditary problems of galactose intolerance (capsules may contain lactose)

It is not approved for routine use in children outside specialist epilepsy care.

Pregnancy: Pregabalin should be avoided in pregnancy unless clearly necessary. Studies suggest a slightly increased risk of birth defects when taken in the first trimester, so women planning pregnancy should discuss alternatives, and effective contraception is advised during treatment. Never stop it abruptly on discovering pregnancy — contact your doctor for a safe plan.

Breastfeeding: Pregabalin passes into breast milk, and its effects on the baby are not well established; it is generally not recommended while breastfeeding. Discuss the safest option with your doctor.

Store Pregabalin below 30°C in a dry place, away from light and moisture, in the original pack. Because pregabalin is a medicine with misuse potential, keep it securely stored and strictly out of the reach of children and others — never leave strips lying around or share them. Do not use after the expiry date on the pack.
