Peritol review

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


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


Common side effects include nausea, vomiting, headaches, hypertension, diarrhea, chest pains, dry mouth, confusion, scratchy throat, and a loss of appetite. Serious side effects, which 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. Bring Peritol patients to a hospital if they show even the slightest sign of an allergic reaction to the medication.


Before taking Peritol there are some precautionary measures that each patient should take. First, tell your physician about any medications, over the counter or prescription, that you are taking. Specifically, your physician should know if you are taking cold medicine, depression medicine, sleeping pills, muscle relaxants, narcotics and even vitamins. Second, tell your physician about any illnesses you have previously contracted. Asthma, diabetes, hyperthyroidism, urinary tract disorders, heart disease, high blood pressure and seizures affect Peritol and how it works in your body. Adult patients should remember that Peritol has a strong sedative effect so driving or operating machinery that can harm others is not suggested especially right after you start taking the medication. The medication has the opposite effect on young children. While adults feel drowsy after taking Peritol, children, especially very young children, become excited and very active.


Pregnant women should be careful when taking this medication since it has not been proven safe for unborn fetuses yet. There might be a risk of abnormalities to the unborn 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 Peritol, since most medications are passed on in breast milk.
