Meteospasmyl: Formula, Indications, Mechanism of Action, Dosage, Side Effects, Warnings, Contraindications and Interactions

It is a drug that is made up of two crucial chemical complexes, which are simethicone and alverine citrate.

Meteospasmyl is a recommended treatment for intestinal disorders, generally of gaseous origin. Thanks to its active molecules, simethicone, and alverine, a better evacuation of intestinal gas are produced, thus reducing discomfort and abdominal pain.

This treatment is recommended only for adults.

Alverine is present in the drug as alverine citrate in a proportion of 60mg for each capsule and is the component that is responsible for calming the pains that occur in the stomach due to stomach disorders.

On the other hand, simethicone is an antiflatulent responsible for eliminating gases and preventing air bubbles that lodge in the stomach and that later will form uncomfortable gases in the intestines.

It is also known as an antifoam agent.

It is present in a proportion of 300mg for each capsule, the main component of the drug.

  • Simeticona C6H18O3Si3.


Meteospasmyl comes in the form of soft capsules to take by mouth, and its formula is Alverine 60 mg and Simethicone 300 mg.


Meteospasmyl is an antispasmodic treatment used for gastrointestinal cramps, bloating in the abdomen, painful periods, dysmenorrhea, painful pressure, hiccups, and other conditions.

Mechanism of action

Meteospasmyl is a treatment that acts on intestinal bloating through a digestive tract recovery mechanism in the form of a bandage.

The intestinal wall is covered with a thin layer of silicone that protects it.

Its active ingredients relax the intestinal muscles and reduce abdominal spasms generated by the accumulation of intestinal gases.

Meteospasmyl improves the patient’s condition by performing the following functions:

  • Relaxing the muscles in the intestine and uterus.
  • Acting on the intestine’s inner lining and allowing gas bubbles to coalesce.


In case of intestinal gas accumulation, it is advisable to take 2 to 3 capsules of 360 mg of meteospasmyl per day, at the beginning of the meal or at the time of pain.
