Dactil Ob is a drug of the antispasmodic type, that is, it serves in the treatment of spasms and is also uterorelaxant. This makes it especially useful for treating and preventing threats of miscarriage and premature birth. It is also useful in treating dysmenorrhea.

This medicine is used mainly in cases of threats of premature births and to combat the threats of abortion due to its relaxing action on the uterus. It works by inhibiting prematurely produced uterine contractions by decreasing smooth muscle motility. Thus, the relaxation tone is returned to the uterus during pregnancy. This medicine is absorbed from the gastrointestinal tract.

Dactil Ob comes as compressed tablets, usually in a box of 30 tablets. Each contains the active substance piperidolate hydrochloride (100 mg), hesperidin (50 mg), and ascorbic acid or vitamin C (50 mg).

What is Dactil Ob for in pregnancy?

The Dactil Ob is especially useful during pregnancies with threatened abortions that begin to present uterine contractions or the initiation of labor before 37 weeks of gestation. That is, before the normal duration of a pregnancy.

So if it is not the right time of pregnancy for delivery to occur, Dactil Ob can decrease uterine muscle spasm and prevent preterm labor.

Dactil ob is one of the most effective anticholinergics (that is, it inhibits the production of the neurotransmitter acetylcholine) that can prevent premature contractions of the uterus. The active substance in this drug, piperidolate, helps decrease involuntary muscle spasms or contractions, which in turn inhibits parasympathetic post-ganglionic nerve impulses.

In this way, it is quite effective in preventing the onset of labor when there is dilation and laying of the cervix or cervix.

The administration of Dactil Ob during pregnancy should only be done under prescription and medical observation. In addition, this drug is an adjunct to the threat of abortion, it must be complemented with other therapies in addition to absolute rest.

After terminating the pregnancy, the drug should be discontinued and not used during lactation. The strict recommendations of the doctor should always be followed in case of using this drug during pregnancy.
