Taking Manidón with food, drinks, and alcohol

Grapefruit juice has been shown to increase plasma levels of verapamil; therefore, Manidón should not be taken together with grapefruit juice.

Consumption of alcohol together with Manidón may enhance the hypotensive effect.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using 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. However, Manidón will only be administered during lactation if essential for the mother's health due to the potential for serious adverse reactions in infants.

Driving and use of machines

Exercise caution when driving or operating tools or machinery, as Manidón may reduce reaction capacity, especially at the beginning of treatment, when the dose is increased, when switching from another medicine, and when alcohol is consumed.

Manidón retard 120 mg prolonged-release tablets contain sodium alginate

This medicine contains less than 23 mg of sodium (1 mmol) per tablet; thus, it is essentially "sodium-free."
