Side Effects of Calmovil

Written by faith davies | 13/05/2017

Calmovil is an herbal dietary supplement advertised for the treatment of haemorrhoids. Despite the fact that they are natural substances, some of the ingredients in Calmovil pose side effect risks for some people.


Because it is an herbal product, Calmovil is not evaluated by the FDA for safety or effectiveness. Its ingredients are also not analysed to determine if there are any harmful or toxic chemicals not listed by the manufacturer that may cause side effects.

Side Effects

Three of the ingredients in Calmovil--diosmin, horse chestnuts and hesperidin--can cause stomach upset, diarrhoea and headaches in some people, according to RxList. Horse chestnut may also cause itchy skin rashes and dizziness.

Drug Interactions

Horse chestnut poses a risk for toxic side effects when combined with the mood stabilising drug lithium, according to RxList. When combined with blood-thinning medications like wafarin, two of Calmovil's ingredients--bilberry and nattokinase--increase the risk of developing prolonged or uncontrollable bleeding following an injury or surgery.


Although rarely, some patients develop severe allergic reactions to horse chestnut.


If you are pregnant or nursing or have a history of latex allergies, kidney or liver disease or diabetes, it may not be safe for you to take Calmovil due to the possible side effects of its ingredients, according to RxList.
