People who suffer from hay fever and various other allergic problems can find a solution for the symptoms when they try a pheniramine drug. Most commonly, the medications sold incorporate pheniramine as an ingredient, although the medicine can also be found without other ingredients. Some common branded drugs that use pheniramine drug are Delhist, Histine, Iohist, Methistine, Multihist, Prohistine and Avil. The generic form of pheniramine can be found under the names of pheniramine, pyrilamine, and phenyltoloxamine. All of these drugs work by the same action: they prevent the negative effects of the body's own histamine. As such, they are all classified as antihistamines, frequently used to treat the conditions of urticaria or hay fever.

These medications can act as a sedative and patients should exercise caution when under the influence of these drugs. Driving a vehicle, operating heavy machinery, and other complex motor activities should be avoided while taking these drugs. In addition, use of alcohol or other drugs may increase the sedative effect experienced by users. Your local doctor should be consulted to determine if pheniramine drug is the best solution. Those patients that have any of the following conditions should be sure to mention them during the visit: kidney disease, diabetes, heart disease, emphysema, enlarged prostate, liver disease, glaucoma, high blood pressure, thyroid disease, or chronic bronchitis. In addition, this medication should not be taken if the patient is also taking a monoamine oxidase inhibitor as well.

The majority of patients who take a pheniramine drug find that there are little to no side effects. The most common side effects are minor and include drowsiness, vision impairment, difficulty in urination, agitated children, and a dryness in the nose, eyes, or mouth. An allergic reaction can also be experienced and will be recognized by the presence of hives, facial swelling, or a problem with breathing.

As there are many different variations of this medication, care should be taken by a patient to use the product only as directed. Liquid forms of the drug should be accurately measured using a measuring spoon or cup. Tablets should be taken whole with water or another liquid. As a general rule, the medication should not be taken for longer than seven continuous days. If there are still problems, your local doctor should be contacted to discuss alternative treatment plans. Pheniramine drug supplies should be kept in a secure location at room temperature out of the reach of children.
