Composition

Methotrexate (15 Mg)

Remtrex 15 MG Injection 3 ML is primarily prescribed to manage severe rheumatoid arthritis, a chronic autoimmune condition that causes painful inflammation and damage to the joints. It belongs to the group of medicines classified as an antimetabolite.

Beyond rheumatoid arthritis, this medicine is also indicated for treating psoriasis, a skin condition marked by red, scaly patches that can be painful and lead to excessive skin cell growth. By slowing down the proliferation of these cells, this medicine helps improve the symptoms and appearance of the skin in psoriasis patients.

Before taking this injection, consult your doctor, who will determine the appropriate dosage and frequency. Make sure you inform your doctor about any pre-existing conditions or ongoing medication. If you notice any side effects while on this medicine, notify your doctor immediately. It's important to continue taking the medicine for the duration prescribed by your doctor for optimal results.

Remtrex 15 MG Injection 3 ML is used for the following:

Management of severe rheumatoid arthritis in adults
Reducing symptoms of severe psoriasis in adults
Controlling symptoms of certain types of cancer, such as breast and lung cancer
Reducing the growth of certain cells in adults with severe leukaemia
Managing advanced stages of non-Hodgkin's lymphoma in adults
Control of severe or disabling psoriatic arthritis in adults
Helping to reduce symptoms in adults with severe ankylosing spondylitis.

Remtrex 15 MG Injection 3 ML is administered by a healthcare professional.
It should be injected into a muscle or vein, as directed by your doctor.

Remtrex 15 MG Injection 3 ML can be taken intravenously, intramuscularly, and subcutaneously.

Remtrex 15 MG Injection 3 ML may cause the following side effects:

Diarrhoea
Hair loss
Skin rash
Liver function abnormality
Mucositis (Inflammation and soreness of the mucous membranes - the soft tissues lining your digestive tract)

Managing the Side Effects:

Most side effects are temporary and generally harmless, which resolve upon discontinuing the use of Remtrex 15 MG Injection 3 ML. However, if you experience any serious side effects or worsening of any of the symptoms, please consult your doctor.

Diarrhoea: Try to ensure that you stay hydrated by drinking plenty of fluids throughout the day.

Remtrex 15 MG Injection 3 ML contains methotrexate (15 mg), which works on the body as follows:

Antimetabolite activity: Methotrexate functions as an antimetabolite, meaning it interferes with cellular metabolism. In simple terms, it disrupts the normal functioning of cells.
Folic acid antagonist: As a folic acid antagonist, methotrexate inhibits an enzyme crucial for the synthesis of folic acid in your body. Folic acid is needed for cell growth and division.
Inhibits inflammation: By inhibiting certain enzymes, methotrexate reduces inflammation in your body. This helps manage symptoms in inflammatory conditions like rheumatoid arthritis and psoriasis.

Pregnancy

Remtrex 15 MG Injection 3 ML is strictly contraindicated during pregnancy. It poses risks to foetal development and should not be used during pregnancy unless specifically prescribed by a specialist.

Breastfeeding

This medication is also not recommended for breastfeeding mothers, as its components can pass into breast milk and may adversely affect the infant. Consult your doctor to discuss alternatives or to weigh the potential risks and benefits before using this medicine if you are breastfeeding.

Alcohol

Combining Remtrex 15 MG Injection 3 ML with alcohol can exacerbate side effects, especially those affecting the liver. It is advisable to avoid alcohol entirely or consult your doctor regarding alcohol intake while on this medication.

Liver

Remtrex 15 MG Injection 3 ML may affect liver function, particularly in individuals with pre-existing liver conditions. If you have a history of liver issues, it’s crucial to inform your doctor. Your doctor may suggest periodic liver function tests and adjust the dosage to minimise potential complications.

Kidney

If you have a history of kidney disease, it’s essential to exercise caution with Remtrex 15 MG Injection 3 ML, as it can impact kidney function. Make sure to inform your doctor about any kidney-related health issues before beginning treatment.

Using Machines & Driving

Remtrex 15 MG Injection 3 ML may cause side effects such as dizziness, fatigue, or drowsiness, which can impair your ability to drive or operate machinery. If you experience these symptoms, take extra care and avoid activities that require mental alertness until you know how the medication affects you.

Allergy

If you're allergic to methotrexate or any other component of Remtrex 15 MG Injection 3 ML, this medication should be avoided. Your doctor can help determine whether this medicine is suitable for you based on your allergy history.

Children

Remtrex 15 MG Injection 3 ML is not intended for use in children under 18 years.

Older Patients

Older patients should take Remtrex 15 MG Injection 3 ML under medical supervision as they may be more susceptible to its side effects. Caution is advised, especially if patients are above 70 years of age. Your doctor can guide you based on your health status.

Drug-Drug Interactions

Remtrex 15 MG Injection 3 ML interacts with the following medicines:

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs): Medicines such as ibuprofen and naproxen can interact with this medicine, potentially increasing the risk of side effects like liver damage.

Antibiotics: Certain types of antibiotics, like tetracycline, may interact adversely with this medicine, potentially leading to increased side effects.

Drug-Food Interactions

High protein foods: Foods rich in protein might affect the absorption of methotrexate from the stomach, impacting its efficacy.

Liver disease: People with liver disease should be cautious as this medicine could potentially exacerbate their condition.
Kidney disease: The medicine could have an adverse effect on patients suffering from kidney disease, as it may further impair kidney function.

Daily Dose

The dose of this injection should be administered as recommended by your doctor. The dosage may vary based on individual factors, such as the severity of the condition and response to treatment. It is usually administered once weekly.

Over Dose

Overdosing of Remtrex 15 MG Injection 3 ML is less likely to occur as it is administered by a healthcare professional. In case of accidental overdose, symptoms such as severe bone marrow suppression, gastrointestinal bleeding, liver damage, and pneumonitis can occur.

Missed Dose

Remtrex 15 MG Injection 3 ML is administered subcutaneously or intravenously by a healthcare professional. In case a dose is missed, inform your doctor immediately.

Since this injection is typically used to manage conditions like rheumatoid arthritis, embrace a balanced diet rich in omega-3 fatty acids. Foods like fish, walnuts and flaxseeds can reduce inflammation.
Regular exercise improves joint flexibility. However, switch to gentle activities like swimming or yoga during flare-ups to avoid straining your joints. Always consult your doctor before starting any new exercise regime.
