Aceclofenac-Tizanidine

What is Aceclofenac-Tizanidine?

Aceclofenac-Tizanidine 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.
• Tizanidine: a muscle relaxant that eases muscle tightness and spasm.

Drug class

The combination belongs to the group of anti-inflammatory and muscle relaxant pain medicines. Aceclofenac is an NSAID, and tizanidine is a centrally acting alpha-2 adrenergic agonist.

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:

• Muscle spasm with pain, 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

Approval status differs by country. This combination is not an FDA-approved product in the United States. Tizanidine is FDA-approved on its own for spasticity, and aceclofenac is not marketed in the United States.

Available formulations and strengths

The most common form is an oral tablet. A typical tablet contains aceclofenac 100 mg and tizanidine 2 mg or 4 mg. Strengths and tablet types (for example, film-coated tablets) vary by manufacturer. Always check the label on your own package.

What is the Recommended Dosage of Aceclofenac-Tizanidine?

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: older adults are often 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, because tizanidine builds up when kidney function is low and is broken down by the liver
• Other medicines: some medicines greatly raise tizanidine levels in the body

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. Take it the same way each time, since food can change how tizanidine is absorbed.
• It is generally meant for short courses. NSAIDs are used at the lowest effective dose for the shortest time needed. See your provider if pain continues beyond the planned period.
• Do not take other NSAIDs or other muscle relaxants at the same time unless your provider tells you to.
• If you have taken tizanidine regularly for a long time or at high doses, do not stop suddenly. Ask your provider how to lower the dose gradually.

How Aceclofenac-Tizanidine 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.
• Tizanidine acts mainly in the spinal cord. It stimulates certain receptors (alpha-2 receptors) that reduce the nerve signals telling muscles to tighten, which helps ease muscle stiffness and spasm.

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-Tizanidine 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.
• 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-Tizanidine

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

Common side effects

• Drowsiness or sleepiness
• Dizziness or lightheadedness, especially when standing up
• Dry mouth
• Tiredness or weakness
• Nausea, indigestion, or heartburn
• Stomach pain, gas, or bloating
• Diarrhea or constipation
• Headache
• Low blood pressure or a slow heart rate
• 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:

• 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)
• Yellowing of the skin or eyes, dark urine, severe tiredness, loss of appetite, or pain in the upper right abdomen (possible liver problems)
• Fainting, severe dizziness, or a very slow heartbeat
• Seeing or hearing things that are not there, or unusual confusion
• 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)
• Sudden swelling in the legs or feet, or much less urine than usual (possible kidney problems)
• Unusual bruising or bleeding

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:

• Fluvoxamine and ciprofloxacin: these medicines can raise tizanidine levels sharply and cause severe low blood pressure and sleepiness. Using them together is not recommended and is contraindicated in the U.S. tizanidine labeling.
• Other medicines that slow the breakdown of tizanidine (such as some other antibiotics and certain heart rhythm medicines): may raise tizanidine levels. Your provider may adjust the dose.
• 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.
• Blood pressure medicines (ACE inhibitors, ARBs, beta-blockers) and diuretics: NSAIDs can reduce their effect and may strain the kidneys, and tizanidine may lower blood pressure further.
• Alcohol, sedatives, sleeping pills, anti-anxiety medicines, opioids, and other muscle relaxants: may add to drowsiness and slowed breathing.
• 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.
• Oral contraceptives and smoking: can change how the body clears tizanidine, so its effect may be stronger in some people.

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

• 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. Tizanidine can also lower blood pressure and slow the heart rate. Use extra caution if you have heart disease or high blood pressure, and stand up slowly.
• Liver: Both ingredients can affect the liver. Tizanidine can raise liver enzymes and, rarely, cause liver injury, and NSAIDs can also affect the liver. Use caution in liver disease. Liver tests may be advised during treatment.
• Kidneys: NSAIDs can reduce kidney blood flow, and tizanidine builds up when kidney function is low. Use caution in kidney disease, dehydration, or heart failure. Kidney function may be monitored.
• Sleepiness: The medicine can cause drowsiness. Avoid driving, operating machinery, or other tasks that need alertness until you know how it affects you. Avoid alcohol.
• Hallucinations: Rarely, tizanidine can cause hallucinations or delusional thoughts. Report these promptly.
• Pregnancy: NSAIDs should generally be avoided in the third trimester and used after about 20 weeks only if clearly advised by a provider, because they may affect the baby’s kidneys and heart circulation. Safety data for tizanidine in pregnancy are limited. Talk to your provider before using this medicine at any stage of pregnancy or if you are trying to conceive.
• Breastfeeding: Not generally recommended unless your provider advises otherwise.
• Children: This combination is generally not recommended for children and adolescents unless a specialist specifically advises it.
• Older adults: More sensitive to drowsiness, low blood pressure, 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. It is a symptom-relief medicine and is not meant to be a long-term solution without medical review. Whether it is suitable for you depends on your medical history, your other medicines, and your specialist’s assessment.

Who Should Not Take Aceclofenac-Tizanidine

Do not take this medicine if you:

• Are allergic to aceclofenac, tizanidine, or any ingredient in the tablet
• Have had asthma, hives, or an allergic reaction after taking aspirin or another NSAID
• Take fluvoxamine or ciprofloxacin
• 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 significantly abnormal liver tests
• Have severe kidney disease
• Have a bleeding disorder
• Are in the third trimester of pregnancy

Use extra caution and speak with your provider first if you have low blood pressure, a slow heart rate, heart rhythm problems, high blood pressure, diabetes, inflammatory bowel disease, mild-to-moderate kidney or liver problems, a history of hallucinations or psychiatric illness, or if you drink alcohol regularly.

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.
