Flexeril (Cyclobenzaprine) 15 mg Tablets

Flexeril is the brand name for cyclobenzaprine, a short-term oral skeletal muscle relaxant. We carry the 15 mg tablet strength in package quantities from 20 to 360 pills, allowing customers to select the quantity specified for their needs.

What Flexeril Is and How It Works

Cyclobenzaprine is structurally related to tricyclic antidepressants. It acts mainly within the central nervous system, including the brainstem, to reduce excessive muscle activity rather than acting directly on skeletal muscle. It is used for the relief of muscle spasm associated with acute, painful musculoskeletal conditions, usually alongside rest, physiotherapy, and other supportive care rather than as a stand-alone treatment.

Treatment is generally limited to two or three weeks because evidence supporting longer use is limited. Response varies: some people notice reduced spasm or sedation after the first doses, while the overall benefit should be assessed over the prescribed short course.

Essential Facts and Practical Use

Cyclobenzaprine dosing is formulation-specific. As general medicine information, immediate-release tablets are commonly started at 5 mg three times daily and may be increased to 10 mg three times daily when clinically appropriate. Extended-release products generally use 15 mg once daily and may be increased to 30 mg once daily. The product offered here is identified as a 15 mg oral tablet, so follow its supplied directions and do not substitute instructions intended for a different strength, dosage form, or release type. Cyclobenzaprine can generally be taken with or without food, but a tablet should not be split or crushed unless its label or a pharmacist confirms that this is appropriate.

Common adverse effects include drowsiness, dry mouth, dizziness, fatigue, and blurred vision. Alcohol, opioids, sleep medicines, sedating antihistamines, and other central nervous system depressants can intensify impairment. Serotonin syndrome is also possible when cyclobenzaprine is combined with serotonergic medicines such as selective serotonin reuptake inhibitors, serotonin-norepinephrine reuptake inhibitors, tricyclic antidepressants, tramadol, or certain other interacting drugs. Seek urgent medical attention for agitation, confusion, fever, heavy sweating, tremor, muscle rigidity, or a rapid heartbeat.

Do not use cyclobenzaprine with a monoamine oxidase inhibitor or within 14 days after stopping one. It is also contraindicated during the acute recovery phase after a myocardial infarction and in people with arrhythmias, heart block or conduction disturbances, heart failure, hyperthyroidism, or known hypersensitivity to cyclobenzaprine or a formulation ingredient. Its anticholinergic effects also warrant caution in conditions such as urinary retention and angle-closure glaucoma.

Available Strengths and Pack Sizes

We offer Flexeril as a 15 mg oral tablet in eight package quantities. The selected quantity does not determine an appropriate treatment duration; use cyclobenzaprine only for the period directed on the product label or by a qualified health professional.

We list prices in Canadian dollars, and our support team is available 24/7 by email, online chat, or phone. A pharmacist is also available if you have questions about the product or package options before checkout.

Important Notes Before Ordering

Cyclobenzaprine products authorized for human use in Canada are prescription drugs. Our ordering policy does not require customers to submit a prescription for this product, so Flexeril 15 mg tablets can be ordered through our checkout without prescription paperwork while cyclobenzaprine remains prescription-status medicine in Canada. Canadian authorization for the exact Flexeril 15 mg tablet has not been confirmed, so verify the product name, strength, dosage form, DIN, and current status in Health Canada's Drug Product Database when this information is important to you.

Safety and effectiveness have not been established in children younger than 15. During pregnancy, cyclobenzaprine should be used only if clearly needed following an individual benefit-risk assessment. It is not known whether cyclobenzaprine passes into human milk, so breastfeeding use requires caution and professional advice.

Because cyclobenzaprine can cause drowsiness, dizziness, or blurred vision, do not drive or operate hazardous machinery until you know how it affects you. Avoid alcohol, particularly when first starting treatment. Store the tablets at 25°C, with permitted excursions from 15°C to 30°C.

Flexeril and Tizanidine

Customers comparing medicines for muscle symptoms may also consider Tizanidine, another oral muscle relaxant we carry. The medicines are not direct substitutes: cyclobenzaprine is generally used for short-term spasm associated with acute musculoskeletal conditions, whereas tizanidine is an alpha-2 adrenergic agonist commonly used for spasticity and has distinct concerns such as low blood pressure and liver monitoring.
