Aceclofenac-Thiocolchicoside

What is Aceclofenac-Thiocolchicoside?

Aceclofenac-Thiocolchicoside is a fixed-dose combination medicine that contains two active ingredients in one tablet:

• Aceclofenac: a nonsteroidal anti-inflammatory drug (NSAID) that helps reduce pain and inflammation.
• Thiocolchicoside: a muscle relaxant that eases painful muscle tightness. It is not the same medicine as colchicine.

Drug class

The combination belongs to the group of anti-inflammatory and muscle relaxant pain medicines. Aceclofenac is an NSAID, and thiocolchicoside is a skeletal muscle relaxant.

Approved and common prescribed uses

This combination is mainly used in some countries, such as India, for short-term relief of painful muscle conditions. Healthcare providers may prescribe it for:

• Painful muscle spasm linked to acute spine conditions, such as acute low back pain or neck pain
• Pain, stiffness, and spasm after sprains or strains
• Painful musculoskeletal conditions where both inflammation and muscle spasm are present

In the European Union, oral thiocolchicoside is approved only as an add-on treatment for painful muscle contractures linked to acute spine conditions in adults and adolescents over 16 years of age, and not for long-term treatment of chronic conditions. Approval status of this combination differs by country, and it is not an FDA-approved product in the United States.

Available formulations and strengths

The most common form is an oral tablet. A typical tablet contains aceclofenac 100 mg and thiocolchicoside 4 mg or 8 mg. Strengths and tablet types vary by manufacturer. Always check the label on your own package.

What is the Recommended Dosage of Aceclofenac-Thiocolchicoside?

The right dose is not the same for everyone. Your healthcare provider decides the dose and the length of treatment based on:

• Condition: the type and severity of pain and spasm
• Age: use is generally limited to adults and adolescents over 16, and older adults are started with extra caution
• Body weight and overall health: especially when other conditions are present
• Kidney and liver function: reduced function may require a lower dose or a different medicine
• Pregnancy and contraception status: this medicine must not be used in pregnancy or breastfeeding
• History of seizures: thiocolchicoside can lower the seizure threshold

Available dosage forms

The combination is generally available as an oral tablet. The number of tablets and how often to take them depends on the product your provider prescribes.

Important dosing points

• Follow the instructions from your licensed medical specialist and the directions on the label.
• This medicine is usually taken with or after food to reduce stomach upset, and swallowed whole with water.
• Treatment should be as short as possible. In the European Union, oral thiocolchicoside is limited to no more than seven days in a row because of the genotoxicity concern, and the recommended dose is not to be exceeded. NSAIDs are also used at the lowest effective dose for the shortest time needed.
• Do not take more than prescribed, and do not take it longer than your provider has planned. If pain continues, see your provider rather than extending treatment yourself.
• Do not take other NSAIDs or other muscle relaxants at the same time unless your provider tells you to.

How Aceclofenac-Thiocolchicoside Works

Each ingredient works in a different way:

• Aceclofenac blocks enzymes called cyclooxygenases (COX). These enzymes help the body make prostaglandins, which are chemicals that cause pain and inflammation. Lower prostaglandin levels can ease pain and swelling.
• Thiocolchicoside is thought to act mainly in the spinal cord and brain. It blocks certain receptors for a calming chemical messenger called GABA, which reduces the nerve signals that cause muscles to tighten.

Together, they aim to ease muscle pain from two angles. This medicine helps manage symptoms. It does not heal the injury or treat the underlying cause of the pain, such as a spine or joint condition.

Is a Prescription Required to Buy Aceclofenac-Thiocolchicoside Online?

In most regions where this combination is sold, it is a prescription-only medicine. Rules can differ by country, so check the regulations where you live.

• Talk with a licensed medical specialist before using it. Depending on your condition, this may be an orthopedic doctor, a rheumatologist, a physical medicine and rehabilitation specialist, a pain management specialist, or your primary care physician.
• Buy only from licensed, verified pharmacies that ask for a valid prescription and are legally permitted to sell the product in your country.
• Be careful of counterfeit or substandard tablets. Signs include damaged packaging, missing batch numbers or expiry dates, spelling errors on the label, and unusual tablet appearance.
• Do not buy from websites that offer the medicine without a prescription or that cannot show pharmacy licensing details.

Side Effects of Aceclofenac-Thiocolchicoside

Most people tolerate this medicine, but side effects can happen. Not everyone has them.

Common side effects

• Nausea, indigestion, or heartburn
• Stomach pain, gas, or bloating
• Diarrhea or constipation
• Drowsiness or sleepiness
• Dizziness or lightheadedness
• Headache
• Mild skin rash or itching

These effects are often mild. Taking the medicine with food may help with stomach upset. Tell your provider if they continue or bother you.

Serious side effects

Serious reactions are uncommon but need prompt care. Stop the medicine and get medical help right away if you notice:

• Seizures or convulsions, since thiocolchicoside can lower the seizure threshold
• Black, tarry, or bloody stools, or vomiting blood or material that looks like coffee grounds (possible stomach or intestinal bleeding)
• Chest pain, shortness of breath, weakness on one side of the body, or slurred speech (possible heart attack or stroke)
• Swelling of the face, lips, tongue, or throat, wheezing, or trouble breathing (possible severe allergic reaction)
• Widespread rash, blistering, or peeling skin (possible severe skin reaction)
• Yellowing of the skin or eyes, dark urine, severe tiredness, or pain in the upper right abdomen (possible liver problems)
• Sudden swelling in the legs or feet, or much less urine than usual (possible kidney problems)
• Severe or ongoing diarrhea or vomiting
• Unusual bruising or bleeding
• Confusion or unusual drowsiness

If you are unsure whether a symptom is serious, contact a healthcare provider or local emergency service.

Drug Interactions

Tell your licensed medical specialist and pharmacist about every medicine you take. Major interaction categories include:

• Other NSAIDs and aspirin (such as ibuprofen, diclofenac, naproxen): raise the risk of stomach bleeding and kidney problems.
• Blood thinners and antiplatelet medicines (such as warfarin, clopidogrel): raise the risk of bleeding.
• Medicines that lower the seizure threshold: such as some antidepressants, antipsychotics, tramadol, and some antibiotics (for example, quinolones). They may raise the risk of seizures when combined with thiocolchicoside.
• Blood pressure medicines (ACE inhibitors, ARBs, beta-blockers) and diuretics: NSAIDs can reduce their effect and may strain the kidneys.
• Corticosteroids and SSRI antidepressants: may increase the risk of stomach bleeding.
• Lithium, methotrexate, digoxin, and ciclosporin: NSAIDs can raise levels of these medicines in the body.
• Alcohol, sedatives, sleeping pills, anti-anxiety medicines, opioids, and other muscle relaxants: may add to drowsiness and slowed breathing.

Over-the-counter medicines, supplements, and herbal products

Over-the-counter pain relievers, cold and flu remedies, and sleep aids may contain NSAIDs or sedating ingredients. Supplements and herbal products that may affect bleeding or cause drowsiness, such as fish oil, ginkgo, garlic, valerian, kava, and St. John’s wort, should be discussed with your provider. Give your provider a complete, up-to-date list of prescription medicines, over-the-counter products, vitamins, supplements, and herbal remedies.

Safety & Important Considerations

• Genotoxicity risk: Laboratory studies found that a breakdown product of thiocolchicoside can cause aneuploidy, which means an unequal number of chromosomes in dividing cells. This is considered a risk factor for harm to an unborn baby, miscarriage, reduced male fertility, and possibly for tumors. For this reason, use at higher-than-recommended doses or for long periods should be avoided.
• Pregnancy and breastfeeding: Must not be used. Women who could become pregnant should use effective contraception during treatment and for a period afterward, and men who are able to father a child should also use effective contraception, as advised by their provider. In the EU guidance, this period is up to one month after treatment for women and up to three months for men. NSAIDs should also be avoided in the third trimester and used after about 20 weeks only if clearly advised, because they may affect the baby’s kidneys and heart circulation.
• Seizures: Thiocolchicoside can trigger seizures, particularly in people with epilepsy or those at risk of seizures, and at higher doses. It should not be used in people with epilepsy or a seizure history unless a specialist directs it.
• Stomach and intestines: NSAIDs can cause ulcers and bleeding, even without warning signs. The risk is higher in older adults, in people with a history of ulcers, and with long-term use.
• Heart and blood vessels: NSAIDs carry a safety warning about a higher risk of heart attack and stroke, which can happen early in treatment and may rise with higher doses or longer use. Use extra caution if you have heart disease or high blood pressure.
• Kidneys: NSAIDs can reduce kidney blood flow. Use caution in kidney disease, dehydration, or heart failure. Kidney function may be monitored.
• Liver: NSAIDs can sometimes raise liver enzymes or cause liver injury. Use caution in liver disease. Liver tests may be advised if treatment is prolonged.
• Sleepiness: Avoid driving, operating machinery, or other tasks that need alertness until you know how the medicine affects you. Avoid alcohol.
• Children: Not recommended for children and adolescents under 16, and generally not recommended in older children unless a specialist advises it.
• Older adults: More sensitive to drowsiness, falls, and stomach, kidney, and heart effects. Lower doses and closer monitoring may be needed.
• Surgery: Tell your surgeon or dentist you take this medicine, since it may increase bleeding.
• Asthma: Some people with asthma react to NSAIDs with breathing symptoms.

Who This Medication Is For

This medicine is typically used by adults who need short-term relief from painful muscle spasm with inflammation, such as acute back pain or neck pain, when a provider decides that both an anti-inflammatory and a muscle relaxant are needed. Because of the genotoxicity concern with thiocolchicoside, it is not a first-choice medicine for everyone. Whether it is suitable for you depends on your medical history, your pregnancy and contraception status, your other medicines, and your specialist’s assessment.

Who Should Not Take Aceclofenac-Thiocolchicoside

Do not take this medicine if you:

• Are pregnant or breastfeeding
• Are a woman who could become pregnant and are not using effective contraception
• Are a man who is able to father a child and does not wish to use effective contraception during treatment and afterward
• Have epilepsy, a history of seizures, or are at risk of seizures
• Are allergic to aceclofenac, thiocolchicoside, or any ingredient in the tablet
• Have had asthma, hives, or an allergic reaction after taking aspirin or another NSAID
• Have an active stomach or intestinal ulcer or bleeding, or a history of repeated ulcers or bleeding
• Have severe heart failure, or are about to have or have recently had heart bypass surgery
• Have severe liver disease or severe kidney disease
• Have a bleeding disorder
• Are under 16 years of age
• Need long-term treatment for a chronic condition

Use extra caution and speak with your provider first if you have high blood pressure, heart disease, diabetes, inflammatory bowel disease, or mild-to-moderate liver or kidney problems.

What to Do If You Miss a Dose

• Take the missed dose as soon as you remember, with food, if you still need it and it is not close to the next dose.
• If it is almost time for your next dose, skip the missed one and continue your normal schedule.
• Do not take two doses at once to make up for a missed dose.
• If you are unsure what to do, contact your licensed medical specialist or pharmacist.

If you think you have taken too much, seek medical help immediately, even if you feel well. Taking too much thiocolchicoside can raise the risk of seizures.
