Topnac contains Aceclofenac (100mg). It belongs to the Non-steroidal anti-inflammatory drug class of medicines.
Treatment of inflammatory conditions associated with Muscle spasm Treatment of Pain due to muscle spasm
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). Thiocolchicoside is a muscle relaxant. It works on the centres in the brain and spinal cord to relieve muscle stiffness or spasm and to improve pain and movement of muscles.
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. Topnac-TH 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 Topnac-TH 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 Topnac 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 at room temperature (below 25°C), protected from light and moisture. Keep out of reach of children.
Topnac-TH Tablet helps relieve pain and muscle spasm that may occur due to strains, sprains, and muscle injuries. It is usually used along with rest and physical therapy. Take it with food to avoid an upset stomach. It may cause dizziness. Do not drive or do anything requiring concentration until you know how it affects you. Avoid consuming alcohol when taking Topnac-TH Tablet as it may cause excessive drowsiness.
