FLO Saline+Plus may also be used by pregnant mothers, and people with sensitive noses because it does not contain any preservatives, alcohol, chemicals or buffers. FLO Saline+Plus helps reduce nasal congestion by washing the nose and thinning mucus. FLO Saline+Plus may be used with other medicated nasal sprays - both prescribed and pharmacist recommended. Use FLO Saline+Plus 10-15 minutes before a medicated nasal spray to cleanse the nasal tissues and help improve the effectiveness of the medicated spray. FLO Saline+Plus is fitted with a pump delivery system which helps to keep the solution sterile without the need for added preservatives and chemicals.
