Flexeril® Tablets for Muscle Spasm

Cyclobenzaprine is a prescription muscle relaxant used for short-term relief of painful muscle spasms. This page explains what it is, how to take it, and what to expect. You can access Canadian pricing with US delivery from Canada, which may help if you pay without insurance.

What Flexeril Is and How It Works

Flexeril® contains cyclobenzaprine, a centrally acting skeletal muscle relaxant. Cyclobenzaprine reduces muscle hyperactivity by influencing brainstem motor pathways, helping ease spasm and related pain. Cyclobenzaprine 10 mg is commonly used for acute musculoskeletal conditions alongside rest and physical therapy.

YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.

This medicine is intended for short courses during acute flares. It does not replace exercises or treatment for the underlying cause of pain. The treatment may be sedating, so many people take it in the evening when appropriate.

Who It’s For

This therapy is for adults with acute muscle spasm linked to strains, sprains, or similar soft-tissue injuries. It is typically used together with rest, heat or ice, and guided stretching. It is not designed for chronic spasticity from neurological conditions.

People who should avoid it include those using MAO inhibitors or within 14 days of stopping one. It may not be suitable with certain heart rhythm problems, hyperthyroidism, or angle-closure glaucoma. Caution is advised in liver impairment and in older adults due to increased sensitivity. It is generally not recommended for children under 15 years.

If you have ongoing neck or back symptoms, see our condition pages on Muscle Spasm and Musculoskeletal Pain for context on causes and care options.

Dosage and Usage

Follow your prescriber’s directions and the official label. Treatment is usually short term, often for up to two or three weeks during an acute episode. Many adults start with lower doses and increase only if needed for symptom control.

Some prescriptions may specify Flexeril 10 mg up to three times daily. Others use lower doses, especially at the start, to reduce drowsiness. Take tablets with a glass of water. You may take it with or without food. Avoid alcohol and other sedatives while on this therapy.

Do not drive or perform tasks requiring alertness until you know how this medicine affects you. If you feel overly sleepy, contact your prescriber for guidance on timing or whether the regimen remains appropriate. Refer to the patient information leaflet for complete instructions.

Strengths and Forms

Tablets are commonly supplied in strengths such as 5 mg and 10 mg. Availability may vary by manufacturer.

Many adults receive cyclobenzaprine 10 mg tablets when a higher tablet strength is prescribed. Your pharmacy may dispense a specific brand or a generic equivalent depending on stock and your prescription.

Missed Dose and Timing

If you miss a dose, take it when you remember unless it is close to the next scheduled time. If it is near the next dose, skip the missed dose and resume the regular schedule. Do not double up to make up for a missed tablet.

Avoid taking doses too late in the evening if drowsiness would interfere with your plans the next day. For questions about timing with other medicines, ask a pharmacist or your prescriber.

Storage and Travel Basics

Store tablets at room temperature in a dry place, away from moisture and direct light. Keep them in the original, child-resistant container unless your pharmacist provides a compliance pack. Always keep medicines out of reach of children and pets.

For travel, carry your prescription-labeled bottle in your hand luggage. Bring a copy of your prescription or an electronic record if available. Keep dosing consistent across time zones as advised by your prescriber. Avoid storing tablets in hot cars or damp bathrooms.

Benefits

This class can help relax tense skeletal muscles, making movement easier during recovery. It may also support better sleep when spasms disturb rest. Most benefit comes when used together with rest, ice or heat, and a structured physical therapy plan.

Because it acts on the central nervous system, it can reduce the pain-spasm cycle that often prolongs acute back or neck pain. Using the lowest effective dose and limiting duration can reduce unwanted effects.

Side Effects and Safety

• Common: drowsiness, dry mouth, dizziness
• Others: fatigue, nausea, constipation, blurred vision

Serious but less common risks include fast or irregular heartbeat, confusion, or allergic reactions such as rash, swelling, or trouble breathing. Seek urgent care for severe reactions. The risk of sedation increases with alcohol, opioids, benzodiazepines, or certain sleep aids. Because cyclobenzaprine is related to tricyclic agents, rare serotonin syndrome has been reported when combined with serotonergic drugs.

Drug Interactions and Cautions

Do not use with MAO inhibitors, or within 14 days of stopping one. Use caution with SSRIs, SNRIs, TCAs, tramadol, or triptans due to serotonin syndrome risk. Additive sedation can occur with alcohol, antihistamines, opioids, benzodiazepines, and other CNS depressants.

Tell your prescriber about heart disease, recent heart attack, arrhythmias, hyperthyroidism, liver problems, urinary retention, or glaucoma. Report all prescription and over-the-counter medicines, vitamins, and herbal products you take.

What to Expect Over Time

With short-term use and rest, many people notice less muscle tightness as healing progresses. Sedation can occur early and may lessen as your body adjusts or with lower doses. If symptoms persist or worsen, follow up with your prescriber to reassess the plan.

Compare With Alternatives

Other muscle relaxants may be considered if sedation or other effects are not acceptable. Two options include Robaxin® (methocarbamol), which may be less sedating for some, and Baclofen, which acts on spinal pathways. Your prescriber will choose based on your health history, other medicines, and response.

Patient Suitability and Cost-Saving Tips

This therapy suits short-term use during an acute flare when rest and physical therapy are also planned. It may not be appropriate for people with specific cardiac conditions, hyperthyroidism, severe liver disease, or those taking MAO inhibitors.

To save, consider a multi-month fill if your prescriber anticipates intermittent use and writes quantity accordingly.
