Periactine review

Periactine is a multi-use medication prescribed mostly for patients with allergies, specifically hay fever, and patients suffering from anorexia. It relieves the sneezing, itching, bloating and watery eyes induced by allergies.


This medication is an anti-histamine with antagonistic tendencies toward serotonin in the body. This medication stops the different chemicals in the body that cause allergic reactions, usually through blood flow control and blood vessel constrictions. A change in serotonin levels affects one's mood, so the anorexia is challenged by Periactine through its antagonistic strategy against serotonin. Periactine is also used to battle insomnia due to its unusually strong sedative effects as an anti-histamine.


Common side effects of Periactine include nausea, vomiting, headaches, high blood pressure, diarrhea, chest pains, dry mouth, confusion, scratchy throat, and a loss of appetite. Serious side effects that may be a sign of an allergic reaction include intense excitement, rashes, problems with vision, difficulty urinating, and weakness in the body. Consult your physician immediately if you experience any of these side effects. It might be best to bring Periactine patients to a hospital if they show even the slightest sign of an allergic reaction to the medication.


Before taking Periactine there are some precautionary measurements that each person should take. First, inform your physician of any medicaments, over the counter or prescription, that you are taking. Specifically, you should reveal if you are taking cold medicine, depression medicine, sleeping pills, muscle relaxants, narcotics and even vitamins. Second, inform your physician about any diseasees you have previously contracted. Asthma, diabetes, hyperthyroidism, urinary tract disorders, heart disease, high blood pressure and seizures can all affect Periactine and how it affects your body. Adult Periactine patients should remember that Periactine specifically has a strong sedative effect so driving or operating machinery that can harm others is not suggested especially after first taking the medication. The medication has the opposite effect on young children. While adults may feel drowsy after taking Periactine, children, especially very young children, tend to become excited and very active.


Pregnant women should be careful when taking this medication since it has not been proven safe for fetuses yet. There might be a risk of abnormalities in the fetus; however it has not been proven. It's better to inform your physician and have him adjust the dosage or give you another medication. Nursing mothers should be careful since this medication might pass through the breast milk. It might be better to stop breastfeeding while on Periactine, since most medicaments are passed on in breast milk.
