Pain relief
Ark 75mg Tablet is a non-steroidal anti-inflammatory drug (NSAID). It works by blocking the release of certain chemical messengers that cause pain and inflammation (redness and swelling).
Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Ark 75mg Tablet should be taken with or after food.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
If you miss a dose of Ark 75mg Tablet, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
An overdose of this medicine can cause stomach bleeding, kidney failure, drowsiness and fits. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.
Most side effects of Ark-75 are mild and settle as the body adjusts. Reported side effects include:
Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

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.
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.
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.
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
You have been prescribed Ark 75mg Tablet to relieve pain and inflammation. Take it with food or milk to prevent upset stomach. Take it as per the dose and duration prescribed by your doctor. Long term use may lead to serious complications such as stomach bleeding and kidney problems. It may cause dizziness, drowsiness or visual disturbances. Use caution while driving or doing anything that requires concentration. Avoid consuming alcohol while taking Ark 75mg Tablet as it can cause excessive drowsiness and increase your risk of stomach problems. Inform your doctor if you have a history of heart disease or stroke. Your doctor may regularly monitor your kidney function, liver function and levels of blood components, if you are taking this medicine for long-term treatment.
