Sugar-Free Cold and Cough Medicine with Antihistamine, Cough Suppressant, and Nasal Decongestant. Our product is made up of natural ingredients, dextromethorphan, brompheniramine, and phenylephrine. Rompe Pecho Flu, Sugar-Free, helps you relieve more effects such as cough, nasal congestion, irritated eyes, and the nose that, besides being congested, drips continuously. It doesn't contain sugar, so a person with diabetes can also take it. Menthol, echinacea, and the other herbal extracts found in Rompe Pecho have a long medical history. Some of these are often used as traditional homemade remedies for treating health ailments and boosting the immune system. While the SF and SF-FLU were formulated with these herbal extracts like the rest of our other Rompe Pecho presentations, they were formulated without honey or sugar, so they are ideal for use by people with diabetes.
