Im 30 weeks pregnant n have a cough is it ok to take glycerin medicine?

Yes, check the ingredients but most glycerin based cough mixtures dont include parecetemols. Even if it did contain them most doctors would say to take the lower dosage and only for a few days then go back. Can i suggest making a hone and lemon tea. Make your tea up minus the milk and add lemon juice and honey to it, helps soothe if nothing else, also prop yourself up in bed with pillows to sop excessive coughing t night and allowing you to get much needed sleep. Hope the cough goes soon, good luck. xxx
