Introduction About LACARNIT INJECTION
LACARNIT INJECTION contains Levocarnitine, which belongs to the group of medicines called amino acid derivatives. It is used to manage levocarnitine deficiency. Levocarnitine deficiency can occur as a result of a congenital deficiency, various metabolic disorders, end-stage kidney disease and haemodialysis management.
The symptoms of levocarnitine deficiency may include muscle weakness (muscles of the hips, shoulders, neck, jaw, and even heart muscles), fatigue, low blood sugar, stomach pain, growth retardation, brain function defects, etc.
Before recommending LACARNIT INJECTION, your doctor may want you to take blood tests to check for the existing amount of levocarnitine in circulation to determine the correct dosage for you. LACARNIT INJECTION is not recommended for use in patients suffering from a history of fits or severely compromised renal function.
Pregnant or breastfeeding women should use LACARNIT INJECTION with caution; therefore, consult your doctor before taking. The most common side effects of taking LACARNIT INJECTION are vomiting, nausea, stomach pain, diarrhea, headache, and an abnormal fish-like body odour (fish-like smell). Contact your doctor if any of the symptoms worsen.
Uses Of LACARNIT INJECTION
LACARNIT INJECTION is used to manage:
- primary systemic carnitine deficiency by birth
- secondary carnitine deficiency due to certain metabolic disorders that result in the accumulation of abnormal and toxic metabolites (Ex. methyl malonic aciduria, propionic acidemia, glutaric aciduria and medium chain fatty acetyl dehydrogenase deficiency
- secondary carnitine deficiency due to hemodialysis
How LACARNIT INJECTION Works
Levocarnitine is a naturally occurring substance in the body that is essential for the energy metabolism of the body. It is utilized in the process of producing energy in the energy-building bodies of our cells (mitochondria). This helps in sustaining the muscular activity of the heart and other muscles.
How to use LACARNIT INJECTION
LACARNIT INJECTION is administered only by a doctor or nurse directly into the veins (intravenously). Your doctor will decide the correct dose and duration for you depending on your age, body weight and disease conditions.

Pregnancy
LACARNIT INJECTION must be used with caution in pregnant and those who are planning to get pregnant women due to a lack of safety data. Consult your doctor before receiving LACARNIT INJECTION.

Breastfeeding
LACARNIT INJECTION must be used with caution in nursing women due to a lack of safety data. Consult your doctor before receiving LACARNIT INJECTION.

Driving and Using Machines
LACARNIT INJECTION is considered safe for driving or while using machinery. However, consult your doctor before receiving it.

Kidney

This medicine must be used cautiously in patients suffering from kidney disorders and undergoing hemodialysis. Consult your doctor before receiving LACARNIT INJECTION.

Allergy
Do not administer LACARNIT INJECTION if you are allergic to Levocarnitine.
Others
LACARNIT INJECTION is not recommended for use if you:
- have a history of fits (seizure activity) as it may lead to a rise in the frequency, duration and severity of the seizures
Before taking LACARNIT INJECTION, inform your doctor if you:

FAQs About LACARNIT INJECTION
Can I administer LACARNIT INJECTION myself at home?
No, LACARNIT INJECTION should only be administered by a registered doctor or nurse, as it is given directly into the veins (intravenously). Consult your doctor before taking it.
What is LACARNIT INJECTION used for?
LACARNIT INJECTION is used to manage carnitine deficiency, which can occur at birth, as a result of certain metabolic disorders, or as a result of a medical procedure such as hemodialysis. This reduced level of levocarnitine results in decreased energy, leading to muscle weakness. LACARNIT INJECTION helps manage these symptoms by managing the deficiency.
How should LACARNIT INJECTION be stored?
LACARNIT INJECTION should be stored at a controlled room temperature of 250 C. It is recommended not to store it in the refrigerator. Also, LACARNIT INJECTION should be kept out of reach of children.
What medications should I not take before or after receiving LACARNIT INJECTION?
Anti-diabetic medications (Ex. Insulin, Metformin), blood-thinning medications (Ex. Aspirin), and medications to manage blood clots (Ex. Heparin, Warfarin) are not recommended to be taken along with LACARNIT INJECTION as they may lead to unwanted side-effects. Inform your doctor about all the medicinal and/or surgical managements that you were, are, or will be undergoing before receiving LACARNIT INJECTION.
Can I drive my way back home after receiving LACARNIT INJECTION?
Yes, you can drive after receiving LACARNIT INJECTION since LACARNIT INJECTION has not been reported to cause disturbance while driving or using machinery. However, consult your doctor before receiving LACARNIT INJECTION.
Is it normal to experience body odour after receiving LACARNIT INJECTION?
Yes, body odour is a common side effect usually seen after receiving LACARNIT INJECTION. Apply a mild deodorant or perfume to the skin to manage it. However, it should be brought to the attention of your doctor if it worsens with time.
Can I receive LACARNIT INJECTION if I am pregnant?
It is recommended to consult your doctor and bring it to his attention if you are pregnant or are planning pregnancy before receiving LACARNIT INJECTION, as its effects have not been studied in pregnant women.
