Rejunex 100mg/500mcg Capsule 10s

Rejunex 100mg/500mcg Capsule 10s is an oral combination of two neuroprotective agents that address peripheral nerve damage through antioxidant, metabolic, and regenerative mechanisms.

Alpha lipoic acid (ALA) is a naturally occurring dithiol compound synthesised endogenously in mitochondria, functioning as an essential cofactor for mitochondrial enzyme complexes including pyruvate dehydrogenase and alpha-ketoglutarate dehydrogenase. Unlike most antioxidants, ALA is soluble in both aqueous and lipid environments, allowing it to neutralise reactive oxygen species and reactive nitrogen species across all cellular compartments. It directly scavenges free radicals including hydroxyl radicals, singlet oxygen, and peroxynitrite, and regenerates other endogenous antioxidants including glutathione, vitamin C, and vitamin E after they have been oxidised. ALA also chelates redox-active transition metals such as copper and iron, preventing metal-catalysed free radical generation. In nerve tissue, it improves endoneurial blood flow and reduces oxidative damage to neuronal lipids, proteins, and DNA, making it particularly valuable in diabetic and toxic neuropathies characterised by chronic oxidative injury.

Methylcobalamin is the neurologically active, methyl-substituted coenzyme form of vitamin B12. Unlike cyanocobalamin, methylcobalamin does not require hepatic conversion and is directly utilised by the nervous system. It functions as a cofactor for methionine synthase, catalysing the conversion of homocysteine to methionine, a reaction essential for S-adenosylmethionine synthesis and the methylation reactions required for myelin basic protein production and maintenance. Methylcobalamin also promotes axonal regeneration by stimulating nucleoprotein synthesis in neuronal cell bodies and enhancing the production of nerve growth factor. It supports the regeneration of damaged myelin sheaths and improves nerve conduction velocity in demyelinated peripheral nerves. Deficiency of vitamin B12 causes subacute combined degeneration with characteristic demyelination of peripheral and central nerve pathways.

Together, these two components address the oxidative, metabolic, and structural components of peripheral neuropathy, providing synergistic neuroprotective and neuroregenerative activity.

The uses of Rejunex 100mg/500mcg Capsule 10s are as follows:

Diabetic Peripheral Neuropathy

Rejunex 100mg/500mcg Capsule 10s is used to relieve symptoms of pain, burning, tingling, and numbness in diabetic peripheral neuropathy by reducing oxidative nerve damage and supporting myelin integrity.

Chemotherapy-Induced Peripheral Neuropathy

It is used to manage and reduce the severity of peripheral neuropathy caused by neurotoxic chemotherapy agents such as platinum compounds and taxanes.

Nutritional and Vitamin B12 Deficiency Neuropathy

Methylcobalamin corrects the neurological consequences of vitamin B12 deficiency, including peripheral nerve demyelination and subacute combined degeneration.

Idiopathic Peripheral Neuropathy

It is used as a neuroprotective combination in patients with idiopathic peripheral neuropathy where oxidative stress and nutritional factors contribute to nerve dysfunction.

Alcoholic Neuropathy

The antioxidant and B12-replenishing properties of this combination support nerve recovery in alcohol-related peripheral neuropathy.

Oxidative Stress-Related Neurological Conditions

Alpha lipoic acid's broad antioxidant action provides neuroprotective benefit in conditions characterised by chronic neuronal oxidative stress.

Here are the benefits of Rejunex 100mg/500mcg Capsule 10s:

• Dual Neuroprotective Mechanism: Alpha lipoic acid reduces oxidative nerve injury while methylcobalamin supports myelin synthesis and axonal regeneration, together addressing both the cause and structural consequences of neuropathy.

• Universal Antioxidant Action: Alpha lipoic acid is active in both fat-soluble and water-soluble cellular compartments, providing broader antioxidant protection than most single-environment antioxidants.

• Endogenous Antioxidant Regeneration: ALA regenerates glutathione, vitamin C, and vitamin E, amplifying the body's own antioxidant defences in nerve tissue.

• Direct Neuroregenerative Support: Methylcobalamin promotes myelin sheath repair and axonal regeneration, addressing structural nerve damage rather than symptoms alone.

• Improved Nerve Conduction: The combination supports restoration of nerve conduction velocity in demyelinated and oxidatively damaged peripheral nerves.

Like all medicines, Rejunex 100mg/500mcg Capsule 10s may cause side effects in some individuals.

Common Side Effects

• Gastrointestinal Discomfort: Nausea, stomach upset, or mild abdominal discomfort may occur with alpha lipoic acid, particularly on an empty stomach.

• Headache: Mild headache may develop during early treatment with alpha lipoic acid.

• Skin Tingling or Flushing: A transient tingling or warm flushing sensation may occur after taking alpha lipoic acid, particularly at higher doses.

Uncommon Side Effects

• Hypoglycaemia: Alpha lipoic acid improves insulin sensitivity and may lower blood glucose levels, particularly in diabetic patients on antidiabetic medicines. Monitoring of blood glucose is advisable.

• Skin Rash: Allergic skin reactions including urticaria or contact dermatitis may develop in sensitive individuals.

• Altered Taste: Mild changes in taste perception have been reported with methylcobalamin supplementation.

Serious Side Effects (Require Immediate Medical Attention)

• Severe Allergic Reaction: Swelling of the face, lips, or throat with difficulty breathing requires urgent medical care.

• Severe Hypoglycaemia: Marked blood glucose lowering, particularly in insulin-dependent diabetics, may require prompt medical attention.

• Peripheral Neuropathy Worsening: If neurological symptoms worsen during treatment, medical review is required to exclude an alternative or progressive underlying cause.

Always consult your doctor if side effects persist or worsen.

To ensure safe use:

• Use exactly as prescribed by your doctor.

• Usually taken orally once or twice daily as directed.

• Alpha lipoic acid is best absorbed on an empty stomach; take thirty minutes before meals where possible.

• Swallow tablets or capsules whole with water.

• Do not discontinue without consulting your doctor.

• Monitor blood glucose regularly if you are diabetic, as alpha lipoic acid may affect insulin sensitivity.

Rejunex 100mg/500mcg Capsule 10s works through two complementary mechanisms providing neuroprotection, antioxidant defence, and nerve regeneration.

Alpha lipoic acid acts as a cofactor in mitochondrial oxidative decarboxylation reactions, maintaining mitochondrial energy metabolism in peripheral neurons. In its reduced form (dihydrolipoic acid), it directly neutralises reactive oxygen and nitrogen species in both lipid and aqueous cellular environments. It chelates pro-oxidant transition metals, regenerates oxidised antioxidants by donating electrons to spent glutathione, ascorbate, and tocopherol molecules, and activates the Nrf2 transcription factor pathway, upregulating endogenous antioxidant enzyme production. In diabetic neuropathy specifically, it improves endoneurial blood flow by restoring nitric oxide-mediated vasodilation in vasa nervorum.

Methylcobalamin functions as the active coenzyme form of vitamin B12 in the methionine synthase reaction, converting homocysteine to methionine. This maintains adequate S-adenosylmethionine availability for methylation of myelin basic protein, essential for myelin sheath maintenance and repair. It promotes axonal regeneration through stimulation of protein and nucleic acid synthesis in the neuronal cell body and supports the upregulation of nerve growth factor, facilitating structural nerve repair. It normalises nerve conduction velocity by supporting remyelination of damaged peripheral axons.

A few practical measures can help improve treatment outcomes and ensure safe use of Rejunex 100mg/500mcg Capsule 10s:

• Take alpha lipoic acid on an empty stomach: Bioavailability of alpha lipoic acid is significantly higher when taken thirty minutes before meals, as food reduces its absorption.

• Monitor blood glucose if diabetic: Alpha lipoic acid improves insulin sensitivity and may lower blood glucose; regular monitoring helps prevent hypoglycaemia, particularly if you are on antidiabetic medicines.

• Avoid alcohol during treatment: Alcohol worsens peripheral nerve damage and counteracts the neuroprotective benefits of both components.

• Maintain consistent daily use: Neuroprotective and neuroregenerative benefits accumulate with consistent use; do not stop treatment prematurely without consulting your doctor.

• Inform your doctor of all medicines: Alpha lipoic acid interacts with antidiabetic medicines and thyroid hormones; a complete medication review ensures safe concurrent use.

Proper storage is important to maintain the stability and effectiveness of Rejunex 100mg/500mcg Capsule 10s:

• Store at room temperature: Keep away from heat, moisture, and direct sunlight.

• Keep in original packaging: Protects tablets or capsules from humidity and light degradation.

• Keep out of reach of children: Store safely to prevent accidental ingestion.

• Check expiry before use: Do not use after the expiry date printed on the packaging.

Rejunex 100mg/500mcg Capsule 10s may be affected by dietary habits. The following should be noted:

• Take on an empty stomach where possible: Food significantly reduces the absorption of alpha lipoic acid. Taking thirty minutes before meals improves bioavailability.

• Avoid alcohol: Alcohol worsens neuropathy and may counteract the therapeutic effects of both components.

• No other significant dietary restrictions required: Methylcobalamin absorption is not significantly affected by food at standard oral doses.

Rejunex 100mg/500mcg Capsule 10s may interact with the following medicines:

• Antidiabetic Medicines (Insulin and Oral Hypoglycaemics): Alpha lipoic acid enhances insulin sensitivity and may potentiate the glucose-lowering effect, increasing the risk of hypoglycaemia. Blood glucose monitoring and dose adjustment may be required.

• Thyroid Hormone Replacements (Levothyroxine): Alpha lipoic acid may inhibit T4 to T3 conversion and reduce the effectiveness of thyroid hormone replacement. Thyroid function should be monitored during concurrent use.

• Chemotherapy Agents: The antioxidant action of alpha lipoic acid may theoretically reduce the efficacy of certain pro-oxidant chemotherapy agents; concurrent use should be reviewed with the treating oncologist.

• Metformin: Long-term metformin use reduces vitamin B12 absorption; methylcobalamin supplementation is particularly important in patients on metformin to prevent deficiency neuropathy.

• Proton Pump Inhibitors and H2 Blockers: These medicines reduce gastric acid and impair vitamin B12 absorption from dietary sources; methylcobalamin supplementation becomes especially relevant in patients on long-term acid suppression therapy.

Rejunex 100mg/500mcg Capsule 10s should be used carefully in the following conditions:

• Diabetes Mellitus: Alpha lipoic acid improves insulin sensitivity and may lower blood glucose, requiring close monitoring and possible dose adjustment of antidiabetic medicines to prevent hypoglycaemia.

• Thyroid Disorders: Alpha lipoic acid may reduce the conversion of thyroxine (T4) to triiodothyronine (T3); patients on thyroid hormone replacement should have thyroid function monitored during treatment.

• Thiamine Deficiency: In patients with concurrent thiamine deficiency, treatment with alpha lipoic acid without thiamine replacement may paradoxically worsen neurological symptoms.

• Vitamin B12 Malabsorption Syndromes: Patients with pernicious anaemia or gastrointestinal malabsorption may require parenteral B12 supplementation rather than oral methylcobalamin to achieve adequate correction.

• Optic Neuropathy: Leber's hereditary optic neuropathy associated with mitochondrial dysfunction may be exacerbated by certain cobalamin forms; specialist review is required before use.

Usually taken once or twice daily as directed by your doctor. Alpha lipoic acid is commonly used at doses of 300 to 600 mg daily for neuropathy indications, and methylcobalamin at 500 to 1500 mcg daily. The specific dose depends on the indication, severity of neuropathy, and formulation strength. Always follow your doctor's prescription.

If a dose is missed, take it as soon as remembered. Do not double the dose to make up for a missed one. Maintain the regular schedule thereafter.
