Uses of Caterpil Capsule

Key benefits

  • inflammation
  • and swelling in conditions that affect joints and muscles. It can help relieve pain in conditions like rheumatoid arthritis and osteoarthritis. But

How Caterpil Capsule works

Caterpil 100mg/20mg Capsule is a combination of two medicines: Aceclofenac and Rabeprazole, which relieves pain. Aceclofenac is a non-steroidal anti-inflammatory drug (NSAID) which works by blocking the release of certain chemical messengers that cause pain and inflammation (redness and swelling). Rabeprazole is a proton-pump inhibitor which prevents damage to the stomach lining caused by Aceclofenac.

Warnings and precautions

Take it with or just after food, and for the shortest time that works. Stop and seek urgent care for black or tarry stools, vomiting blood, or severe stomach pain — this group can cause bleeding from the stomach. Long or high-dose use raises the risk of heart attack, stroke and kidney injury, particularly in older people and those already at risk. Avoid if you are dehydrated or have an illness with vomiting or loose motions — the kidneys are vulnerable then. Must be avoided in the last three months of pregnancy. Take it on an empty stomach, about half an hour to an hour before your first meal — this is when the acid pumps are most active and the medicine works best. Long-term use has been linked to low magnesium and low vitamin B12, and to a higher risk of bone fracture. Review the need with your doctor rather than continuing indefinitely. Tell your doctor if acidity comes with difficulty swallowing, vomiting, weight loss, or black stools — these need investigation, not a longer course. Do not stop a long course abruptly; acid can rebound. Your doctor will taper it.

Do not take Caterpil if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Not for people with an active stomach ulcer, severe kidney or heart failure, or asthma triggered by aspirin or anti-inflammatory painkillers. Not in the third trimester of pregnancy.

Interactions with other medicines

Combining with a blood thinner or aspirin sharply raises the bleeding risk. Reduces the effect of blood pressure medicines and water tablets, and together with them can harm the kidneys. Never take two anti-inflammatory painkillers at the same time. Reduces the absorption of some antifungals, iron and certain HIV medicines. Tell your doctor if you take clopidogrel, methotrexate or a blood thinner.

How to store Caterpil Capsule

Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.

Expert advice for Caterpil Capsule

Take it as per the dose and duration prescribed by your doctor. Long term use may lead to serious side effects. It may cause dizziness and sleepiness. Don't drive or do anything that requires mental focus until you know how Caterpil 100mg/20mg Capsule affects you. Inform your doctor if you are pregnant, planning to conceive or breastfeeding. Your doctor may regularly monitor your kidney function, liver function and levels of blood components if you are taking this medicine for long duration.
