What works for colds

Whether the penetration of the cold viruses into the mucous membrane cells of the nose can be prevented by using so-called cold or defence sprays, which put a protective film on the mucous membrane, is not conclusively clarified. A strong protective effect is rather not to be expected. Carragelose (Alcovir®), hypromellose (First Defence Micro-Gel Spray Wick) and glycerol with the peptidase trypsin (ViruProtect Cold Spray) are used as film formers. In order to achieve the greatest possible protection, the application should start with the cold period and then be used continuously. If possible, the protective film should always be placed on the mucous membranes when cold viruses are likely to be in the air we breathe. Depending on the type of preparation, it is sprayed several times a day.

If the nose is congested, decongestant nasal sprays or drops (decongestives) are the best choice. They can quickly and effectively improve the symptoms of a runny or blocked nose. The active ingredient is an α-sympathomimetic such as xylometazoline or oxymetazoline. The preparations should be used consistently at the recommended dosage to keep the nose open and to prevent secretion congestion. The effect lasts five to eight hours.

Pregnant women who suffer from colds can use decongestant nasal drops without any concerns. But it is not always a cold when pregnant women have the feeling that their nose is blocked. During pregnancy, hormones improve the blood supply to the nasal mucous membranes, making them slightly swollen. This is nothing to worry about. The nasal application of saline solution can relieve the symptoms.

Dosage sprays are advantageous for decongestives because, in addition to an exact dosage, they ensure a good distribution of the active substance solution in the nose. They are especially recommended for use in children, older children can use them themselves under supervision. Nasal sprays and drops are available in different concentrations for different age groups. The use of topical α-sympathomimetics in infants is not without controversy due to possible systemic side effects. As an alternative, PTA and pharmacists can recommend a physiological saline solution for the very youngest.
