Valethamate
Uses of Valethamate
Valethamate is an antispasmodic medicine used mainly to help dilate the cervix during the first stage of labour.
Valethamate is commonly used for:
• Cervical dilation during labour: Helps relax the cervix, making it easier for it to widen during the first stage of childbirth.
• Cervical spasm during labour: Helps reduce spasm of the cervical smooth muscle to facilitate cervical dilatation.
Valethamate is given only in a hospital or clinical setting under the supervision of a doctor.

How Valethamate works
Valethamate belongs to a group of medicines called anticholinergics or antispasmodics.
It works by blocking the action of acetylcholine, a natural chemical messenger that causes smooth muscle to contract. By blocking this action on the smooth muscle of the cervix, Valethamate helps the muscle fibres relax.
This relaxation makes the cervix more pliable, helping it to soften and dilate more easily during the first stage of labour.
