Tonophosphan Injection (Toldimfos Sodium) | Used for Metabolic Disorders & Phosphorus Deficiency

Precaution

1. Veterinary Use Only

Tonophosphan Injection is intended for animals and should not be used in humans. Administration should be carried out by, or under the supervision of, a qualified veterinarian.

2. Correct Animal and Dose

The dose depends on the species, body size, weight, condition, and reason for treatment. Do not use a human dosing schedule or estimate the dose without veterinary guidance.

3. Kidney Problems

Animals with kidney disorders may require additional caution when receiving phosphorus-containing preparations. Tell the veterinarian about any known kidney disease before treatment.

4. Mineral Imbalance

If the animal has a calcium, magnesium, or phosphorus imbalance, the underlying mineral abnormality should be properly assessed. Tonophosphan may be used together with calcium or magnesium therapy in certain conditions.

5. Pregnancy and Reproductive Conditions

Inform the veterinarian if the animal is pregnant, recently delivered, or being treated for infertility or reproductive problems. The treatment plan should be based on the animal's individual condition.

6. Other Medicines and Supplements

Tell the veterinarian about all medicines, mineral preparations, vitamins, and supplements being given to the animal. This is particularly important when calcium, magnesium, or vitamin D preparations are being used at the same time.

7. Injection Technique

The injection should be administered using an appropriate sterile technique and by the recommended route. Improper injection technique can cause local complications.

8. Follow the Treatment Schedule

Do not repeat injections more frequently or continue treatment for longer than recommended by the veterinarian.

Usage 

• Tonophosphan Injection should be used only according to veterinary instructions.
• The route of administration may be intravenous, intramuscular, or subcutaneous depending on the animal and clinical situation.
• The dose should be calculated according to the animal's species, size, weight, and condition.
• In some acute conditions, treatment may be repeated at short intervals according to veterinary assessment.
• Chronic conditions may require a course of treatment rather than a single injection.
• Do not change the dose or frequency without consulting the veterinarian.
• When treating horses, the recommended injection quantity may need to be distributed across several injection sites.
