Periactin is a brand name for cyproheptadine, a medicatine that reduces the natural chemical histamine in the body (an antihistamine). It helps to reduce and eleminate various allergy symptoms caused by histamine, such as sneezing, runny nose, watery eyes, itching and the like.
When taking Periactin, it is best to follow your physician's instructions to the dot. Do not increase the dosage or the term of treatment on your own free will. Before giving Periactin, or any other cold or allergy medicine, to a young child, it is necessary to consult with a doctor, since the misuse of such medical preperation in infants has been shown to be fatal. If you are using Periactin in liquid form, measure the dose with a special device (a marked spoon or cup) to get precise results. Very often such a device can be found in the medicine pack, otherwise you can ask for one at your local pharmacy. Remember to store Periactin at room temperature away from destructive factors such as heat, moisture, and light.
The most common Periactin side effects include but are not limited to mild drowsiness, nausea, dizziness, appetite changes, sleep problems. The drug may also cause more dangerous symptoms, such as seizure, easy bruising/bleeding, dark colored urine, urinating less than usual, severe weakness spells, pounding heartbeats, confusion, hallucinations, unusual way of thought. If you have noticed any of these happening to you, contact your doctor at once.
