Drug Class: Multivitamin and Mineral Supplement | Form: Oral Tablet | Prescription Status: Available Without Prescription (OTC) — DRAP Registered
What is Surbex Z Tablet? Surbex Z is a comprehensive high-potency multivitamin and zinc supplement combining ten essential micronutrients in a single daily tablet — specifically formulated to address multiple nutritional deficiencies simultaneously. Its unique combination of high-dose Vitamin C 500mg, therapeutic Zinc 22.5mg, complete B-Complex, and Vitamin E 30 IU addresses the most common nutritional gaps seen in the Pakistani population — particularly during illness recovery, periods of high physical or mental stress, poor dietary intake, and conditions with increased micronutrient demand. Unlike basic multivitamins, Surbex Z contains clinically meaningful doses of each nutrient — sufficient to correct deficiencies and support measurable physiological functions rather than merely providing token supplementation. It is particularly valued for immune support, energy metabolism, skin and wound healing, and neurological health maintenance.
What is Surbex Z Used For?
- Multivitamin and mineral deficiency — correcting multiple simultaneous nutritional deficiencies (وٹامنز اور معدنیات کی کمی)
- Immune system support — Vitamin C and Zinc provide combined immune enhancement (قوت مدافعت کو مضبوط کرنا)
- Post-illness recovery — replenishing depleted micronutrients after infection or surgery (بیماری کے بعد صحت یابی)
- Stress-related nutritional depletion — B-Complex replenishment during physical and mental stress (ذہنی اور جسمانی تھکاوٹ)
- Wound healing support — Zinc and Vitamin C are critical for collagen synthesis and tissue repair (زخم بھرنے میں مدد)
- Skin health — Zinc, Vitamin C, and B vitamins support healthy skin maintenance (جلد کی صحت)
- Energy metabolism — complete B-Complex supports carbohydrate, fat, and protein energy conversion (توانائی میں اضافہ)
- Neurological health — B vitamins including B1, B6, B12, and Folic Acid support nerve function
How Does it Work? Each ingredient in Surbex Z addresses specific physiological functions. Vitamin C 500mg is a powerful antioxidant essential for collagen synthesis, immune cell function, iron absorption, and protection against oxidative stress. Zinc 22.5mg supports over 300 enzymatic reactions — critical for immune function, wound healing, protein synthesis, DNA replication, and skin integrity. The B-Complex vitamins collectively serve as essential coenzymes in energy metabolism — Thiamine B1 for carbohydrate metabolism, Riboflavin B2 for cellular energy production, Nicotinamide for NAD synthesis, Pantothenic acid for coenzyme A formation, Pyridoxine B6 for protein and neurotransmitter metabolism, and Cyanocobalamin B12 with Folic Acid for DNA synthesis and red blood cell formation. Vitamin E 30 IU provides additional antioxidant protection — protecting cell membranes from oxidative damage and supporting immune function. Together these ten nutrients provide synergistic comprehensive nutritional support across multiple body systems.
Dosage and Administration
⚠️ Never exceed one tablet daily without medical advice — high-dose Vitamin C and Zinc can cause gastrointestinal side effects in excess. Take with or after food to improve absorption and reduce stomach discomfort. Long-term use beyond 3 months should be reviewed by a doctor. Zinc at therapeutic doses can interfere with copper absorption with prolonged use.

Who Should NOT Take Surbex Z?
- Allergy to any vitamin, mineral, or excipient component of the tablet
- Haemochromatosis or iron overload conditions — Vitamin C significantly increases iron absorption which can worsen iron overload
- Wilson's disease — zinc supplementation may interfere with copper metabolism management
- Hypercalcaemia — some formulation excipients may contain calcium
- Severe kidney impairment — high-dose Vitamin C increases oxalate production and kidney stone risk
- Pregnancy — Folic Acid 150mcg is below the 400mcg recommended for pregnancy; consult obstetrician for appropriate prenatal supplementation
- Patients on Warfarin — Vitamin E at supplemental doses may enhance anticoagulant effect
Side Effects Surbex Z is generally very well tolerated at the recommended once-daily dose. Side effects at standard dosing are uncommon and mild.
Common: Mild nausea or stomach discomfort — particularly if taken on an empty stomach (خالی پیٹ نہ لیں)، mild diarrhoea — particularly with high-dose Vitamin C at 500mg, urine discolouration — bright yellow urine from Riboflavin B2 is harmless and expected (پیشاب کا پیلا رنگ — بے ضرر اور متوقع), mild metallic taste from Zinc component.
Serious — Seek medical attention if: Kidney stones — severe flank pain with blood in urine suggesting oxalate stone formation from high-dose Vitamin C in susceptible patients (گردے کی پتھری — فوری ڈاکٹر کو بتائیں), signs of Zinc toxicity with excessive prolonged use — nausea, vomiting, and severe stomach cramps, significant copper deficiency with very prolonged high-dose Zinc use — anaemia and neurological symptoms (طویل استعمال میں تانبے کی کمی — ڈاکٹر کو بتائیں), severe allergic reaction — sudden widespread rash or swelling of face or throat (فوری مدد لیں).
Drug Interactions
| Medicine | Interaction |
|---|---|
| Iron supplements | Vitamin C 500mg significantly increases iron absorption — beneficial for iron deficiency anaemia but potentially harmful in iron overload conditions |
| Warfarin / blood thinners | Vitamin E at supplemental doses may enhance anticoagulant effect — INR monitoring recommended for patients on anticoagulant therapy |
| Tetracycline / Doxycycline antibiotics | Zinc reduces absorption of tetracycline antibiotics — take at least 2 hours apart |
| Ciprofloxacin / Fluoroquinolone antibiotics | Zinc reduces fluoroquinolone absorption — take at least 2 hours apart |
| Penicillamine | Zinc reduces Penicillamine absorption — take at least 2 hours apart |
| Levodopa / Carbidopa | Pyridoxine B6 may reduce Levodopa effectiveness in Parkinson's patients not on Carbidopa — consult neurologist |
| Metformin | Long-term Metformin reduces B12 absorption — Surbex Z's 12mcg B12 may help partially offset this depletion |
| Antiepileptics (Phenytoin, Carbamazepine) | May reduce Folic Acid levels — supplementation important; however Folic Acid can also reduce antiepileptic blood levels |
| Alcohol (شراب) | Significantly depletes B-Complex vitamins — Surbex Z supplementation particularly valuable in patients with alcohol-related nutritional depletion |
Storage: Store below 25°C in a cool, dry place. Protect from moisture and direct sunlight. Keep in original packaging. Keep out of reach of children (بچوں کی پہنچ سے دور رکھیں). Do not use after expiry date.
FAQs
Q: Why does Surbex Z turn urine bright yellow and is this harmful? The bright yellow urine colour after taking Surbex Z is caused by Riboflavin (Vitamin B2) — a water-soluble vitamin that is excreted in urine when intake exceeds the body's immediate needs. This is completely harmless and is actually a normal indicator that the tablet has been absorbed and the body is processing the B vitamins. The colour typically intensifies within 2 to 4 hours of taking the tablet and fades within the same day.
Q: Is Surbex Z suitable for pregnant women as a prenatal supplement? Surbex Z is not ideal as a standalone prenatal supplement — it contains only 150mcg Folic Acid whereas pregnancy requires a minimum 400mcg daily (ideally 800mcg to 1000mcg) for neural tube defect prevention. Pregnant women should consult their obstetrician for a specifically formulated prenatal supplement with the appropriate Folic Acid dose. Surbex Z may be used alongside prenatal supplements only under medical guidance to avoid duplicate nutrient excess.
Q: Can Surbex Z be taken indefinitely for general health and immunity maintenance? Surbex Z can be taken long-term for genuine nutritional deficiency management — however routine supplementation beyond 3 months should be reviewed by a doctor. Prolonged high-dose Zinc supplementation depletes copper and prolonged high-dose Vitamin C increases kidney stone risk in susceptible patients. For healthy individuals with adequate dietary intake, short targeted supplementation courses during illness recovery or periods of increased demand are more appropriate than indefinite daily use.
