The earlier in the stage of labour that treatment is given, the longer will be
the period of abolition of uterine contraction. Once the cervix is fully dilated or
the foetal feet are passing into the cervical area, the product will only delay
parturition for a maximum of a few hours.

None

medicinal product to the animal
When using do not eat, drink or smoke. After use, wash any contaminated
skin immediately with soap and clean water. This product contains
clenbuterol, a beta-agonist. Accidental self-injection may cause
tachycardia and tremor. These effects may be reversed by the use of a
non-selective beta-blocker. If accidental self-injection occurs seek medical
advice immediately, avoiding driving if possible.
Clenbuterol decreases the tonus of the uterine muscles. Pregnant women
should avoid any risk of exposure to Planipart and should not administer
the product.
