Before using Prefrin Liquifilm

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Children may be especially sensitive to the effects of phenylephrine. This may increase the chance of side effects during treatment. In addition, the 10% strength is not recommended for use in infants. Also, the 2.5 and 10% strengths are not recommended for use in low birth weight infants.

Geriatric

Repeated use of 2.5 or 10% phenylephrine may increase the chance of problems during treatment with this medicine. In addition, heart and blood vessel problems have occurred more often in elderly patients than in younger adults.

Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Interactions with medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking this medicine, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
