Clinical information

Sensiblex 40 mg/ml Solution for Injection for Cattle — SPC Details

Source: VMD Summary of Product Characteristics (SPC). Last updated 26 Mar 2026.

Cows, heifers:
-
canal is insufficiently opened.
-
muscular contractions of the uterus.
Heifers:
-

For intramuscular use.
Heifers: 10.0 ml product (400 mg Denaverine hydrochloride / animal)
Cows: 10.0 ml product (400 mg Denaverine hydrochloride / animal)
Timing of product administration:
-
as parts of the foetus are within the cervical canal and abdominal pressing has
already started.
-
the product can be administered immediately after the veterinary surgeon has
determined that insufficient opening of the soft birth canal is present (please also
refer to section 4.3 [contraindications] and 4.4 [special warnings] of the SPC).
In cases where full dilation is not achieved, product administration may be repeated
once after 40 – 60 minutes.

Do not administer in cases of mechanical obstetrical obstructions.
Do not use in cases of hypersensitivity to the active substance or to any of the
excipients.

Increased restlessness; swellings at the injection site; absent or insufficient
effectiveness necessitating further obstetric diagnostics and measures.

The product is ineffective if no part of the foetus has already entered the cervical
canal and if abdominal pressing has not started.
Before administering the product it is important to ensure there are no mechanical
obstructions (e.g. oversized foetus, malpresentation, uterine torsion). If present,
obstructions must be removed prior to product administration (e.g. correction of
abnormal presentation or uterine torsion).
Signs of peripartum electrolyte imbalances (with special attention to calcium and
phosphorus), as well as metabolic disturbances (e.g. ketosis), both possibly causing
weak labour and thus insufficient dilation of the soft birth canal, require particular
consideration and supportive measurements.

Special precautions for use in animals
None.
Special precautions to be taken by the person administering the veterinary medicinal
product to animals
The product has a potential to affect uterine musculature. Therefore, pregnant
women and those women who are attempting to conceive should not handle or
administer the product.
Administration should be performed with caution in order to avoid accidental self-
injection.
In case of accidental self-injection, seek medical advice immediately and show the
package leaflet or the label to the physician.
Accidental spillage onto skin or into the eyes should be thoroughly rinsed off with
water.
People with known hypersensitivity to denaverine hydrochloride or to any of the
excipients should not administer the product.
Wash hands after use.

The product should not be mixed with other veterinary medicinal products. In the
case of additional administration of oxytocin or its analogues, the dose of this active
substance must be carefully selected because denaverine may amplify its effects.
