Pheniramine Side Effects

Pheniramine is the name of an antihistamine. It is often combined with a decongestant and works to relieve allergy symptoms. It is a major component to many medications. It works to obstruct histamine's effects. Histamine is a chemical that occurs naturally within the body. Pheniramine manages and stops watery eyes, sneezing and other uncomfortable symptoms that are caused by allergies. As with any type of medication, there are some possible side effects that are associated with use of Pheniramine.

  1. Common Side Effects

    • There are some common side effects caused by Pheniramine that are generally considered to be minor and subside quickly on their own. These side effects include a tinging sensation and redness of the eyes. If these effects persist or intensify, it is advised to seek medical attention.

    Serious Side Effects

    • On the other hand, there are also some serious, potentially harmful side effects that could result from Pheniramine use. In the case of serious side effects, one should cease using the antihistamine and receive immediate medical attention. Some of the effects are vision changes, blurry vision, irritation and redness, eye ache and seeing "halos" surrounding areas of light.

    Allergic Reactions

    • Some people also might experience allergic reactions as a side effect of Pheniramine. If an individual should notice signs of allergic reaction, they should seek medical assistance. Some signs of potential allergic reaction are breaking out into hives, having a hard time breathing, skin rash and swelling of the tongue, throat, lips and mouth.

    Overdose

    • If a person suspects that she has overdosed on Pheniramine, she should stop using it immediately and get emergency medical help. Some signs of Pheniramine overdose are excitation, hallucinations, fever, extreme sleepiness, delirium, seizures, tremors, loss of balance, fast heartbeat, enlarged pupils, feelings of depression, dry mouth, anxiety, flushed skin, nausea and throwing up.

    Drug Interactions

    • It is advised that individuals taking Pheniramine avoid using MAO inhibitors during as well as before and after treatment with the medication (two weeks before, and two weeks afterward). This is due to the possibility of a life-threatening drug interaction occurring as a result of the MAO inhibitor and the Pheniramine. Those taking certain migraine medicines (such as naratriptan and ergotamine) should also consult their physicians about Pheniramine use, as the decongestant component of the medication could make side effects worse for them. Anti-seizure medications and other types of medications that induce drowsiness, muscle relaxants, psychiatric medication, and narcotic pain reducers are all drugs that could possibly interact negatively with Pheniramine.
