Among the drugs to relieve pain or postoperative spasmodic, the Buscapina (Butylscopolamine) is one of the most employees . Its composition makes it an effective resource, in a wide range of situations in which our health is impaired. But what are its applications, its contraindications or possible side effects? Next, we find out.

How to take Buscopan: recommended doses

This abdominal antispasmodic is a derivative of scopolamine and hyoscine that has analgesic, antispasmodic and antipyretic properties . Its composition in quaternary ammonium, a common alkaloid in plants of the Duboisia family , prevents it from damaging the central nervous system .

It is used mainly to alleviate the pain produced by abdominal cramps and spasms of the gastrointestinal, biliary and genitourinary system , which also reduces the secretions of these glands. Its analgesic effect, acting on smooth muscles, cuts pain at the root and is suitable in the following cases:

  • Syndrome Irritable bowel .
  • Cramps and disturbances of the digestive system.
  • Menstrual spasms
  • Antisecretory in urinary ulcers.
  • Muscular weakness.
  • After surgery or severe trauma.

Buscopan can be administered orally (tablets or lozenges), rectally (suppositories) or parenterally (muscular, subcutaneous or intravenous injections) . The specialist will decide, under his assessment, the relevant route and dosage.

Although the recommended daily amounts, in adult patients and children older than 6 years, should not exceed 60-80 mg orally or rectally; and 100 mg, if this is parenteral, the characteristics of each patient (age, history, current pathology …) will determine the dose that best suits their needs.

The conventional dosage aims to dilute 30 drops in a glass of water 3 times a day or take one tablet every 8 hours for at least 3 days . However, certain pathologies will cancel the oral and rectal routes and advise the subcutaneous as a priority form of administration. We refer to:

  • Inability to swallow
  • States of low consciousness (comatose or agonizing).
  • Oral cancer
  • Intestinal obstruction and vomiting.
  • Repeated intolerance to oral administration.

This subcutaneous administration will be invalidated in those circumstances, very rare, that present:

  • Generalized edema.
  • Weakened peripheral circulation.
  • Clotting problems
  • Recurrent infections at the injection sites.

Contraindications of Buscopan

Although there are no clinical studies, Buscopan has category C risk, in case of pregnancy ; Therefore, its use is discouraged during pregnancy, especially in the first trimester, unless the doctor considers its application essential for the obvious benefit of the mother and justifies possible damage to the fetus.

In lactation, on the other hand, there is evidence of its inhibitory activity in milk, which reduces its production. Due to this incompatibility, it should not be administered during lactation; and it must be suspended, if its administration is unavoidable.

Interactions with other medications

It can create addiction , if it is combined with other antispasmodics; and it is contraindicated, if we are being treated with antihistamines, tricyclic antidepressants or medication capable of reducing gastrointestinal mobility , as well as in patients with liver or kidney failure.

Although rare, allergic reactions to Buscopan have occurred in the form of hives , nausea, vomiting, or a choking sensation, requiring urgent medical attention. Other signs of eventual overdose poisoning are:

  • Absence of urine
  • Eruptions
  • Palpitations
  • Paralysis of the intestine.
  • Vision or breathing disorders.

Buscopan side effects

The most common sequelae are drowsiness and dry mouth , which subside after a few days. Therefore, it is recommended to avoid driving or manipulating dangerous machinery during its administration, as well as sucking on ice, eating candy or resorting to artificial saliva to counteract such discomfort.

Other possible consequences are:

In the most serious cases, its ingestion may be accompanied by:

  • Swelling of the feet and hands.
  • Tachycardias
  • Diarrhea.
  • Insomnia .
  • Dizziness, especially if its administration is parenterally.
  • Eye pain.

If these symptoms persist for more than three days, it will be necessary to see a doctor to reverse the situation and adopt alternative measures .

Its administration should be carried out with caution, in the elderly and children, as well as in:

  • Down syndrome patients.
  • Hypertensive
  • Sufferers of hyperthyroidism .
  • People with heart disease.
  • Chronic constipation.
  • Low-grade fever.

How to store Buscopan

It is recommended to keep the medicine out of the reach of children, in a dry and cool place, not exceeding 30º C; and, preferably, in its packaging, to protect it from light and to be able to confirm the expiration date.

If we want pharmacotherapy to fulfill its mission, in addition to scrupulously following the guidelines set by the specialist, it is advisable not to double the dose, if we have forgotten to take it; and, especially, if the next hour is close.

If the discomfort does not subside in several weeks or even worse, it will be essential to notify our doctor. Only if we act with prudence and common sense will we contribute to the maintenance of our well-being.
