Description
Spasrid (40mg) 4ml Injection is an antispasmodic medication supplied as a box of 6 ampoules, each containing 4ml of injectable solution. Its active ingredients are Phloroglucinol and Trimethylphloroglucinol, which act directly on smooth muscle to relieve spasms without relying on the anticholinergic pathways used by many older antispasmodic drugs. Spasrid is commonly used to relieve pain caused by spasms in the gastrointestinal tract, biliary system, and urinary tract, offering a fast-acting option for patients experiencing acute colicky pain. Because of its targeted, non-anticholinergic mechanism, it tends to be well tolerated across a wide range of patients, including those who may not be suitable candidates for other classes of antispasmodic medication.
Ingredients
Each 4ml ampoule of Spasrid contains Phloroglucinol 40mg along with a small amount of Trimethylphloroglucinol as active ingredients, together with pharmaceutical excipients that maintain the solution’s stability and suitability for intramuscular or intravenous administration.
Dosage Form
Spasrid is presented as a clear solution for injection, supplied in 4ml ampoules, packaged six to a box, intended for administration by intramuscular (IM) or intravenous (IV) injection.
Uses
Spasrid Injection is used for the symptomatic relief of pain related to functional disorders of the gastrointestinal tract and biliary system, as well as spasms affecting the urinary tract. It is commonly used for conditions such as abdominal cramps, bloating, renal colic, biliary colic, and painful spasms associated with kidney stones or gallstones. It may also be used to relieve severe menstrual cramping when prescribed by a doctor.
How to Use
Spasrid must be administered by a trained healthcare professional via intramuscular or intravenous injection, with the injection site cleaned thoroughly beforehand to reduce the risk of infection. The dosage and frequency depend on the severity of the patient’s symptoms and their clinical response, and should always be determined by the prescribing doctor. Because intravenous administration can affect blood pressure if given too quickly, it should be given slowly and carefully. This medication should never be self-administered.
Side Effects
Spasrid is generally well tolerated, though side effects can occur. Commonly reported effects include nausea, dizziness, headache, and mild irritation or redness at the injection site. Less frequently, patients may notice palpitations or a mild drop in blood pressure, particularly if the injection is given too quickly. Rare but more serious reactions include allergic responses such as hives, swelling, or difficulty breathing, which require immediate medical attention. Patients with kidney or liver impairment should be monitored closely, as dosage adjustments may be needed.
Pregnancy & Breastfeeding
Spasrid should only be used during pregnancy or while breastfeeding if a doctor confirms it is appropriate after assessing the potential risks and benefits for the individual patient. It should not be used without medical guidance in these situations, and alternative options should be discussed with a healthcare provider if needed.
Storage Instructions
Spasrid ampoules should be stored in a cool, dry place, below 25°C, away from direct sunlight and moisture. Keep the ampoules in their original packaging until ready for use, and store them safely out of the reach of children. Do not use any ampoule beyond its printed expiry date.
