Vitamin A (Retinol) + Vitamin B5 (Pantothenic Acid) + Vitamin B2 (Riboflavin) + Vitamin B1 (Thiamine) + Vitamin D3 (Cholecalciferol) is a concentrated sterile solution of fat-soluble and water-soluble vitamins formulated for intravenous infusion. It belongs to the Multi-Vitamin Infusion (M.V.I.) class and is used to provide essential micronutrients to patients who are unable to receive adequate nutrition orally or via the digestive tract. The formulation combines Vitamin A and Vitamin D3 with key B-complex vitamins, including Thiamine (B1), Riboflavin (B2), and Pantothenic Acid (B5). Vitamin A (Retinol) + Vitamin B5 (Pantothenic Acid) + Vitamin B2 (Riboflavin) + Vitamin B1 (Thiamine) + Vitamin D3 (Cholecalciferol) is typically administered intravenously in a clinical setting as part of supportive care during illness, surgery, or recovery.

Vitamin A (Retinol) + Vitamin B5 (Pantothenic Acid) + Vitamin B2 (Riboflavin) + Vitamin B1 (Thiamine) + Vitamin D3 (Cholecalciferol) is an injectable multivitamin infusion designed for parenteral administration. It is indicated as a daily multivitamin supplement for patients receiving intravenous nutrition and for those with acute nutritional depletion, where the oral route is contraindicated or inefficient.

Each component in the infusion serves a vital physiological role: Vitamin A (Retinol) is essential for maintaining the integrity of epithelial tissues, immune function, and vision. Vitamin D3 (Cholecalciferol) is the primary regulator of calcium and phosphate homeostasis, necessary for bone mineralisation. The B-vitamin complex serves as an enzymatic engine: Vitamin B1 (Thiamine) is a coenzyme in carbohydrate metabolism; Vitamin B2 (Riboflavin) is critical for cellular respiration and energy production; and Vitamin B5 (Pantothenic Acid) is a precursor to Coenzyme A, which is essential for the metabolism of fatty acids and the synthesis of various hormones.

By delivering these vitamins directly into the systemic circulation, Vitamin A (Retinol) + Vitamin B5 (Pantothenic Acid) + Vitamin B2 (Riboflavin) + Vitamin B1 (Thiamine) + Vitamin D3 (Cholecalciferol) ensures 100% bioavailability, bypassing the gastrointestinal barriers that often limit absorption in critically ill patients. It helps maintain metabolic balance and supports tissue repair during periods of high physiological stress. The solution is typically diluted in larger volumes of intravenous fluids and administered under close clinical supervision.

Vitamin A (Retinol) + Vitamin B5 (Pantothenic Acid) + Vitamin B2 (Riboflavin) + Vitamin B1 (Thiamine) + Vitamin D3 (Cholecalciferol) may be indicated by your doctor for:

• Nutritional support in hospital patients who cannot take food or supplements orally, such as those recovering from surgery, severe trauma, or burns.

• Correction or prevention of nutritional deficiencies in patients with chronic illness, malnutrition, or conditions that impair absorption through the digestive tract.

• Support during parenteral nutrition (IV feeding) when vitamins cannot be provided through diet.

• Clinical management of increased metabolic demands, for example, during severe infection, prolonged illness, or recovery from major medical procedures.

Vitamin A (Retinol) + Vitamin B5 (Pantothenic Acid) + Vitamin B2 (Riboflavin) + Vitamin B1 (Thiamine) + Vitamin D3 (Cholecalciferol) may provide benefits such as:

• Rapid Correction of Deficiencies: Bypasses the gut to deliver essential nutrients directly to the bloodstream for immediate use.

• Metabolic Support: Ensures the presence of cofactors needed for energy production and the breakdown of macronutrients.

• Enhanced Recovery: Supports the synthesis of proteins and the repair of tissues after physical trauma or surgery.

• Bone and Immune Maintenance: Provides fat-soluble vitamins necessary for skeletal strength and the body's natural defence systems.

• Prevention of Secondary Complications: Helps avoid the neurological and metabolic complications associated with acute vitamin depletion.

Vitamin A (Retinol) + Vitamin B5 (Pantothenic Acid) + Vitamin B2 (Riboflavin) + Vitamin B1 (Thiamine) + Vitamin D3 (Cholecalciferol) is generally well-tolerated when infused at the correct rate, but side effects can occur.

Common side effects of Vitamin A (Retinol) + Vitamin B5 (Pantothenic Acid) + Vitamin B2 (Riboflavin) + Vitamin B1 (Thiamine) + Vitamin D3 (Cholecalciferol) may include:

• Bright yellow urine (due to Riboflavin/B2, which is normal and harmless)

• Flushing or a feeling of warmth during the infusion

• Mild nausea

Uncommon side effects of Vitamin A (Retinol) + Vitamin B5 (Pantothenic Acid) + Vitamin B2 (Riboflavin) + Vitamin B1 (Thiamine) + Vitamin D3 (Cholecalciferol) may include:

• Headache

• Dizziness

• Localised irritation or pain at the site of the intravenous line

Serious side effects that may require immediate medical attention include:

• Signs of a severe allergic reaction (hives, difficulty breathing, or swelling of the face and throat)

• Symptoms of Vitamin A toxicity (severe headache, blurred vision, or persistent dizziness)

• Signs of hypercalcemia (excessive thirst, frequent urination, or muscle weakness)

Always inform your healthcare provider if you experience any unusual symptoms during the infusion.

• Vitamin A (Retinol) + Vitamin B5 (Pantothenic Acid) + Vitamin B2 (Riboflavin) + Vitamin B1 (Thiamine) + Vitamin D3 (Cholecalciferol) is given by a doctor or nurse in a hospital or clinical setting.

• It is administered through a vein (intravenous infusion), usually when you are unable to take enough nutrition by mouth.

• The medicine is first mixed with a suitable fluid before being given.

• It is given slowly over a period of time as directed by your healthcare provider.

• Do not try to self-administer this medicine.

• The dose and duration depend on your nutritional needs and medical condition.

Vitamin A (Retinol) + Vitamin B5 (Pantothenic Acid) + Vitamin B2 (Riboflavin) + Vitamin B1 (Thiamine) + Vitamin D3 (Cholecalciferol) provides a combination of essential vitamins directly into the bloodstream to help maintain normal metabolic function when dietary intake or absorption is inadequate.

Vitamin A (retinol) is converted in the body to active forms that help maintain normal vision, epithelial tissue integrity, and immune function. It also plays a role in cell growth and differentiation.

Vitamin D3 (cholecalciferol) is metabolised in the liver and kidneys to its active form, which acts through vitamin D receptors to regulate calcium and phosphate balance. This supports normal bone mineralisation and skeletal health.

Thiamine (B1), riboflavin (B2), and pantothenic acid (B5) act mainly as coenzymes in energy metabolism. Thiamine is essential for carbohydrate metabolism and nerve function, while riboflavin supports redox reactions involved in cellular energy production. Pantothenic acid is a component of coenzyme A, which is required for the metabolism of carbohydrates, fats, and proteins.

Overall, Vitamin A (Retinol) + Vitamin B5 (Pantothenic Acid) + Vitamin B2 (Riboflavin) + Vitamin B1 (Thiamine) + Vitamin D3 (Cholecalciferol) helps restore and maintain vitamin levels in patients with inadequate intake or increased requirements. This supports normal energy production, cellular function, and recovery during illness or periods of physiological stress.

• This medicine is given by intravenous infusion in a hospital or clinical setting. It should not be self‑administered at home.

• The infusion may be prescribed if clinically necessary. However, high doses of Vitamin A and D3 can be harmful. Always inform your doctor if you are pregnant or breastfeeding.

• Patients with liver or kidney disease may require close monitoring, as fat‑soluble vitamins (A and D3) can accumulate and cause toxicity. Blood tests may be performed to check vitamin and mineral levels.

• Do not take additional vitamin tablets or injections unless advised by your healthcare provider. Combining supplements may increase the risk of overdose.

• Some patients may experience mild nausea, headache, or flushing during infusion. Report any unusual symptoms such as vision changes, persistent vomiting, or bone pain to your doctor immediately.

• Store the Vitamin A (Retinol) + Vitamin B5 (Pantothenic Acid) + Vitamin B2 (Riboflavin) + Vitamin B1 (Thiamine) + Vitamin D3 (Cholecalciferol) at room temperature or as specified by the manufacturer (some formulations may require refrigeration).

• Keep Vitamin A (Retinol) + Vitamin B5 (Pantothenic Acid) + Vitamin B2 (Riboflavin) + Vitamin B1 (Thiamine) + Vitamin D3 (Cholecalciferol) in their original carton until use, as vitamins A and B2 are sensitive to light.

• Do not freeze the solution.

• Keep out of the reach of children.

• General Diet (NO INTERACTION): Since this medicine is given intravenously, food in the stomach does not affect its absorption or effectiveness.

• Retinoids (SEVERE): Avoid use with medicines such as isotretinoin. The combination significantly increases the risk of Vitamin A toxicity.

• Thiazide Diuretics (MODERATE): May raise the risk of hypercalcemia when used with Vitamin D3. Monitoring of calcium levels is advised.

• Seizure Medications (e.g., Phenytoin) (CAUTION): These drugs can increase the breakdown of Vitamin D, reducing its effectiveness.

• Levodopa (MODERATE): Certain B‑vitamins may interfere with the effectiveness of Parkinson’s medicines. Inform your doctor if you are on levodopa.

• Hypervitaminosis (SEVERE): Do not use if you already have toxic levels of Vitamin A or Vitamin D. This may worsen toxicity.

• Hypercalcemia (SEVERE): Contraindicated in patients with high blood calcium levels, as Vitamin D3 may increase calcium further.

• Sarcoidosis (CAUTION): This condition may increase sensitivity to Vitamin D, leading to elevated calcium levels. Careful monitoring is required.

Overdose is very unlikely because this medicine is given in carefully controlled doses by healthcare professionals. However, if your doctor suspects toxicity, the infusion will be stopped immediately, and you will receive supportive care to manage the symptoms.

In a hospital setting, the timing is managed by clinical staff. If an infusion is delayed, the medical team will adjust the schedule.
