Indomethacin

What is Indomethacin?

Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID). It helps reduce pain, swelling, and inflammation in the body.

It is commonly prescribed for:

•  Rheumatoid arthritis
•  Osteoarthritis
•  Ankylosing spondylitis
•  Acute gout attacks
•  Shoulder bursitis or tendonitis
•  Certain types of moderate to severe pain

Indomethacin is available in several forms:

 Oral capsules

• Indomethacin 25mg
• Indomethacin 75mg SR Capsules
• Indomethacin 75mg SR Tablets

1.  Extended-release capsules
2.  Oral suspension (liquid)
3.  Rectal suppositories

It is not a steroid and not an opioid. It works by reducing inflammation but does not cure chronic joint diseases.

What is the Recommended Dosage of Indomethacin?

The correct dose depends on:

•  The condition being treated
•  The severity of symptoms
•  Age
•  Kidney and liver function
•  Overall health

Available dosage forms include:

 Immediate-release capsules

• Indomethacin 25mg

 Extended-release capsules

• Indomethacin 75mg SR Capsules
• Indomethacin 75mg SR Tablets

 Oral liquid suspension

•  Rectal suppositories

Dosing must follow the instructions of a licensed medical specialist. Higher doses or long-term use increase the risk of serious side effects. Patients should use the lowest effective dose for the shortest duration needed.

Do not change the dose without medical guidance.

How Indomethacin Works

Indomethacin blocks enzymes called COX-1 and COX-2. These enzymes help the body produce prostaglandins, which cause:

•  Pain
•  Swelling
•  Fever
•  Inflammation

By lowering prostaglandin levels, indomethacin reduces inflammation and discomfort.

It helps control symptoms but does not stop the progression of underlying diseases such as arthritis.

Is a Prescription Required to Buy Indomethacin Online?

Yes. Indomethacin is a prescription-only medication in most countries.

Because it carries risks such as stomach bleeding and heart complications, it must be prescribed by a licensed medical specialist, such as:

•  A rheumatologist
•  An orthopedic specialist
•  A general physician

Patients should:

•  Avoid websites that do not require a prescription
•  Avoid unverified international pharmacies
•  Avoid veterinary-labeled products

Purchase only from licensed pharmacies to reduce the risk of counterfeit or unsafe products.

Side Effects of Indomethacin

Common Side Effects

These are usually mild:

•  Stomach pain
•  Nausea
•  Heartburn
•  Headache
•  Dizziness
•  Diarrhea

Taking the medication with food may reduce stomach discomfort.

Serious Side Effects

Serious risks may include:

•  Stomach or intestinal bleeding
•  Ulcers
•  Heart attack or stroke
•  Kidney damage
•  High blood pressure
•  Severe allergic reactions

Seek immediate medical attention if you experience:

•  Chest pain
•  Shortness of breath
•  Black or bloody stools
•  Vomiting blood
•  Sudden weakness or slurred speech

Long-term use increases these risks.

Drug Interactions

Indomethacin can interact with many medications.

Major interaction categories include:

 Blood thinners (e.g., warfarin)

•  Other NSAIDs
•  Aspirin
•  Corticosteroids
•  Blood pressure medications
•  Diuretics
•  Lithium
•  Methotrexate

Over-the-counter medications such as ibuprofen or naproxen should not be combined without medical advice.

Patients must provide a complete list of:

•  Prescription medications
•  OTC drugs
•  Herbal supplements
•  Vitamins

This helps reduce the risk of harmful interactions.

Safety & Important Considerations

NSAIDs may increase the risk of heart attack and stroke, especially with long-term use or high doses.

Pregnancy

Indomethacin should generally be avoided in the third trimester of pregnancy. It may harm the unborn baby.

Older adults are at higher risk for bleeding, kidney injury, and heart complications.

Monitoring may include:

•  Blood pressure checks
