Drug Class: High-Dose Therapeutic Vitamin D3 Supplement (Cholecalciferol) | Form: Oral Tablet | Status: OTC Supplement — DRAP Registered | Pack: 30 Tablets | Manufacturer: ABS Nutritions, Pakistan
What is ABS D-Tab 10,000 IU?
D-Tab is a high-dose Vitamin D3 supplement by ABS Nutritions providing 10,000 IU (250mcg) of Cholecalciferol per tablet. It is designed for the treatment of confirmed severe Vitamin D deficiency under medical supervision — not for routine daily supplementation. At 10,000 IU — 2.5 times the internationally recognised safe daily upper limit of 4,000 IU — D-Tab must only be used under doctor's guidance with a confirmed blood test showing significant deficiency and regular monitoring of Vitamin D and calcium levels throughout the course of treatment.
What is D-Tab Used For?
- Treatment of severe and confirmed Vitamin D deficiency (وٹامن ڈی کی شدید کمی)
- Treatment of osteomalacia — soft bones in adults (ہڈیوں کا نرم ہونا)
- Prevention and treatment of rickets under medical supervision (سوکھا روگ)
- Rapid restoration of Vitamin D levels in confirmed deficiency (وٹامن ڈی کی سطح بحال کرنا)
- Supporting bone mineral density and reducing fracture risk (ہڈیوں کی مضبوطی)
- Supporting calcium and phosphorus absorption correction
- Supporting immune system function in severe deficiency states (قوت مدافعت)
- Reducing muscle weakness and neuromuscular dysfunction linked to severe deficiency (عضلاتی کمزوری)
How Does D-Tab Work?
Cholecalciferol (Vitamin D3) is absorbed in the small intestine and transported to the liver — where it is converted to 25-hydroxyvitamin D (the storage and measurable form). It is then activated in the kidneys to calcitriol — the hormonal active form — which regulates intestinal calcium and phosphorus absorption, maintains serum calcium for bone mineralisation, modulates immune cell activity, supports neuromuscular function, and reduces systemic inflammation. At 10,000 IU, D-Tab provides a high therapeutic dose that rapidly saturates Vitamin D stores — correcting deficiency significantly faster than standard 400–4000 IU daily supplements. This makes it appropriate for short-term intensive correction protocols under medical supervision, not for indefinite unsupervised daily use.
Dosage and Administration
| Indication | Dose | Frequency |
|---|---|---|
| Severe deficiency correction | 1 tablet (10,000 IU) | As prescribed — NOT daily without supervision |
| Weekly loading protocol | 1 tablet (10,000 IU) | Once weekly — under doctor's guidance |
| Alternate day protocol | 1 tablet (10,000 IU) | Every 2–3 days — as directed by doctor |
⚠️ 10,000 IU significantly exceeds the internationally recognised safe daily upper limit of 4,000 IU. Do not take one tablet every day without direct medical supervision and regular blood monitoring. Take with a meal containing fat — Vitamin D3 is fat-soluble and requires dietary fat for optimal absorption. Your doctor will determine the correct dosing frequency and duration based on your blood test results. Never self-prescribe this dose.
Active Ingredients
| Ingredient | Strength per Tablet |
|---|---|
| Cholecalciferol (Vitamin D3) | 10,000 IU (250 mcg) |
Who Should NOT Take D-Tab?
- Patients with hypercalcaemia — already high blood calcium levels (خون میں کیلشیم کی زیادتی)
- Patients with hypervitaminosis D — already excess Vitamin D levels
- Patients with kidney stones — high-dose Vitamin D dramatically increases urinary calcium (گردے کی پتھری)
- Patients with sarcoidosis or granulomatous diseases — dangerously heightened sensitivity to Vitamin D
- Patients with severe kidney disease — without nephrologist supervision
- Children — 10,000 IU is an adult therapeutic dose; paediatric dosing must be calculated by a paediatrician
- Pregnant or breastfeeding women — only under specialist medical supervision at this dose
- Patients with hypersensitivity to Vitamin D3 or any tablet excipient
- Anyone self-medicating without a confirmed blood test showing severe deficiency
Side Effects
Common (usually from unsupervised daily use or excessive dosing):
- Nausea or loss of appetite
- Constipation or dry mouth
- Headache or fatigue
Serious (Stop immediately and seek emergency medical attention if):
- Signs of hypercalcaemia or Vitamin D toxicity — excessive thirst, frequent urination, confusion, severe muscle weakness, irregular heartbeat, mental changes (یہ طبی ہنگامی صورتحال ہے)
- Kidney pain or significantly reduced urine output
- Severe nausea, vomiting, or significant loss of appetite with continued use
- Sudden worsening of any existing kidney condition
Drug Interactions
| Medicine / Substance | Possible Interaction |
|---|---|
| Thiazide diuretics (e.g., Hydrochlorothiazide) | Increase calcium reabsorption — combined with 10,000 IU raises hypercalcaemia risk significantly |
| Digoxin (heart medicine) | Hypercalcaemia from high-dose Vitamin D increases Digoxin toxicity risk — potentially fatal |
| Calcium supplements | Combined use raises risk of dangerously high blood calcium — monitor levels very closely |
| Cholestyramine / Orlistat | Reduce fat-soluble vitamin absorption — Vitamin D3 absorption significantly reduced |
| Anticonvulsants (e.g., Phenytoin, Carbamazepine) | Accelerate Vitamin D breakdown — monitor D3 levels and adjust dosing interval accordingly |
| Magnesium supplements | Vitamin D and Magnesium are interdependent — Magnesium deficiency impairs D3 activation; beneficial combination when both are deficient |
| Other Vitamin D supplements | Absolute contraindication — never combine with any additional Vitamin D source at this dose |

Frequently Asked Questions (FAQs)
Q: Can D-Tab 10,000 IU be taken every day like a regular vitamin?
No, 10,000 IU daily significantly exceeds the safe upper intake level of 4,000 IU and carries a real risk of Vitamin D toxicity and hypercalcaemia with prolonged unsupervised use. Your doctor will prescribe the correct frequency — whether daily for a short correction period, weekly, or every few days — based on your blood test results and clinical assessment.
Q: Do I need a blood test before taking D-Tab 10,000 IU?
Yes, a baseline 25-hydroxyvitamin D blood test is essential before starting high-dose supplementation. This confirms the severity of deficiency, guides your doctor in setting the correct dosing protocol, and provides a baseline for monitoring improvement. A follow-up test after 6 to 8 weeks is also necessary to assess response.
Q: How is D-Tab 10,000 IU different from ABS Sulvit-D 5000 IU?
Both are high-dose therapeutic supplements — D-Tab provides double the dose of Sulvit-D. Sulvit-D at 5000 IU is appropriate for significant deficiency correction with daily use under monitoring. D-Tab at 10,000 IU is reserved for severe deficiency requiring rapid correction — typically on a less-than-daily schedule as prescribed by a doctor.
Q: How long should D-Tab be taken?
Duration is determined entirely by your doctor based on serial blood test results. Most high-dose correction protocols last 6 to 12 weeks — after which the dose is reduced to a maintenance level of 400–2000 IU daily. Never continue 10,000 IU supplementation indefinitely without ongoing blood monitoring.
