Warnings and precautions
Consult your doctor, pharmacist, or nurse before starting to take Manidón.
Your doctor will have to be particularly careful when administering this medicine:

Some medicines, if taken together with Manidón, can change its effect. If you use or have used any of the following medicines, consult your doctor:
Taking Manidón with food, drinks, and alcohol
It has been observed that grapefruit juice increases the plasma levels of verapamil, so Manidón should not be taken together with grapefruit juice.
Taking alcohol together with Manidón can enhance the hypotensive effect.
Pregnancy, breastfeeding, and fertility
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
There is no experience with the use of Manidón during pregnancy. Consult your doctor if you become pregnant while taking Manidón.
Verapamil is excreted in breast milk in small amounts. Limited data from human studies suggest that the use of verapamil may be compatible with breastfeeding. Manidón will only be administered during breastfeeding if it is essential for the mother's health due to possible serious adverse reactions in breastfed infants.
Driving and using machines
Be careful when driving or using any tool or machinery, as Manidón can reduce your reaction ability, especially at the beginning of treatment, when the dose is increased, when changing from another medicine, and with alcohol consumption.
