Alternatives LactMed lists
“No published information” means the studies do not exist yet — not that Cyclamate is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
