Pregnancy and breast-feeding

Slo-Phyllin is not recommended for pregnant women in their first trimester and should only be taken during the second and third trimesters if the doctor considers it absolutely necessary, as theophylline can cross the placenta.

Newborn babies should be momtored carefully for the effects of theophylline, if Slo-Phyllin is taken during pregnancy. Slo-Phyllin should be used with caution in breast-feeding mothers, as theophylline is excreted in breast milk. If necessary, breast-feeding should take place immediately before administration of Slo-Phyllin and the infant should be carefully monitored for any effects of theophylline. If you are pregnant or breast-feeding, think you might be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Slo-Phyllin can affect the ability to react, and therefore you should take extra care when driving, using machinery, and when working at heights or without sure footing. The effect will be worsened if Slo-Phyllin is taken with alcohol or other medicines that can also affect the ability to react
