Why is this medication prescribed?
Cold, allergy, and hay fever-related nasal irritation are all treated with phenylephrine. Furthermore, sinus pressure and congestion are reduced by it. Phenylephrine will cure symptoms but not their underlying causes or hasten healing. The drug phenylephrine belongs to the group of drugs known as nasal decongestants. It reduces nasal channel blood vessel enlargement, which is how it functions.
How should this medicine be used?
You can get phenylephrine as a tablet, a liquid, or a strip that dissolves in your mouth. Typically, it is taken as needed every four hours. Ask your doctor or chemist to explain any instructions you do not understand and carefully follow the advice on your prescription label or the packaging label. Just as prescribed, take phenylephrine. Use it just as instructed by your doctor or the label; do not take more, less, or more frequently.
Both alone and in combination with other drugs, phenylephrine is available. Find out which product is best for your symptoms by seeing your doctor or chemist. When combining two or more over-the-counter cough and cold medications, carefully read the labelling. If you take these products together, you can experience an overdose because they might both contain the same active ingredient. This is crucial if you plan to give children cough and cold drugs.
Products that contain phenylephrine, especially those sold without a prescription, can have fatal side effects in young infants. Provide these goods to kids who are under the age of four not at all. If you provide these goods to kids between the ages of 4 and 11, use caution and pay close attention to the instructions on the container.
You should carefully read the package label before providing phenylephrine or a combination product containing phenylephrine to a kid to ensure that it is the proper medication for a child of that age. Products containing phenylephrine intended for adults should not be given to children.
Check the package label before giving a child a phenylephrine product to determine how much of the medication the youngster needs to take. Use the dose on the chart that corresponds to the child’s age. If you are unsure about how much medication to give the child, consult their doctor.
Do not measure your dose if you are consuming the drink with a regular spoon. Use a spoon designed specifically for measuring medication, the measuring cup that came with it, or both.
Stop taking phenylephrine and make an appointment with your doctor if your symptoms do not improve within 7 days or if you develop a fever.
Put one of the dissolving strips on your tongue and wait for it to dissolve if you’re taking them.

What should I know about storage and disposal of this medication?
Keep this medication tightly closed in the original container and out of the reach of children. Keep it away from excessive heat and moisture at room temperature (not in the bathroom).
Although many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning. http://www.upandaway.org
Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your chemist or the garbage/recycling agency in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medications website at http://goo.gl/c4Rm4p for additional information.
