What is Dantrolene Sodium?
Dantrolene sodium is a medication used to treat muscle spasms and stiffness caused by certain medical conditions, such as spinal cord injury, stroke, multiple sclerosis, cerebral palsy, and amyotrophic lateral sclerosis (ALS). It is also used to treat malignant hyperthermia, a potentially life-threatening reaction to certain drugs used during surgery. Dantrolene sodium is a muscle relaxant, meaning it works by blocking the transmission of nerve impulses to the muscles. It is available as an oral capsule, an injectable solution, and a powder for intravenous injection.

Do You Need a Prescription for Dantrolene Sodium?
Yes, dantrolene sodium is a prescription medication. It is important to speak with your doctor before taking dantrolene sodium, as it can interact with other medications and cause serious side effects. Your doctor will also be able to provide you with the necessary coupons, copay, and medication guide for dantrolene sodium.

How Does Dantrolene Sodium Work?
Dantrolene sodium works by blocking the release of calcium from the sarcoplasmic reticulum, a specialized organelle in muscle cells. This reduces the amount of calcium available to activate the muscle contraction process, leading to a decrease in muscle spasms and stiffness. Dantrolene sodium is also used to treat malignant hyperthermia, a potentially life-threatening reaction to certain drugs used during surgery. It works by blocking the release of calcium from the sarcoplasmic reticulum, which helps to reduce the amount of calcium available to activate the muscle contraction process, leading to a decrease in muscle rigidity and spasms.

Common Side Effects of Dantrolene Sodium
Common side effects of dantrolene sodium include nausea, vomiting, diarrhea, constipation, dizziness, drowsiness, headache, blurred vision, dry mouth, and muscle weakness. Less common side effects may include confusion, depression, difficulty sleeping, and rash. If you experience any of these side effects, contact your doctor immediately.

What Should You Not Take with Dantrolene Sodium?
You should not take dantrolene sodium with other medications that can cause drowsiness, such as sleeping pills, antihistamines, muscle relaxants, and narcotic pain relievers. You should also avoid drinking alcohol while taking dantrolene sodium, as it can increase the risk of side effects. It is important to speak with your doctor before taking any other medications while taking dantrolene sodium.

Indications for Dantrolene Sodium

Dantrolene sodium is a medication used to treat a variety of muscle spasticity conditions. It is most commonly used to treat spasticity caused by cerebral palsy, multiple sclerosis, spinal cord injury, and stroke. Additionally, it is used to treat malignant hyperthermia, a rare but serious condition caused by certain anesthetic agents. Dantrolene sodium works by blocking the release of calcium from the sarcoplasmic reticulum, which helps to relax the muscles.

Dosage and Administration Recommendations

The recommended dosage of dantrolene sodium for the treatment of spasticity is 2.5 mg per kg of body weight per day, divided into four doses. The dose may be increased up to 10 mg per kg of body weight per day, divided into four doses, if needed. Dantrolene sodium should be taken with food to reduce the risk of gastrointestinal side effects.

Common Drug Interactions

Dantrolene sodium can interact with other medications, including anticonvulsants, antihistamines, and anticholinergics. It can also interact with certain supplements, such as St. John’s wort. It is important to tell your doctor about all medications and supplements you are taking before starting dantrolene sodium.

Warnings

Dantrolene sodium can cause serious side effects, including liver damage, increased risk of infection, and abnormal heart rhythm. It can also cause drowsiness, dizziness, and blurred vision. It is important to tell your doctor if you are pregnant or breastfeeding before taking dantrolene sodium.

Clinical Pharmacology

Dantrolene sodium is a muscle relaxant that works by blocking the release of calcium from the sarcoplasmic reticulum. This helps to relax the muscles and reduce spasticity. It is metabolized by the liver and excreted in the urine.

Medication Guide

It is important to follow your doctor’s instructions when taking dantrolene sodium. Do not take more or less than the prescribed dose. Do not stop taking dantrolene sodium without talking to your doctor first. Tell your doctor about any side effects you experience while taking dantrolene sodium.
