What is Periactin and why is it prescribed? Periactin is an antihistamine given to help relieve cold and allergy related symptoms such as hay fever, nasal inflammation, stuffy nose, red and inflamed eyes, hives, and swelling. Periactin may also be given after epinephrine to help treat anaphylaxis, a life-threatening allergic reaction. Some doctors prescribe Periactin to treat cluster headache and to stimulate appetite in underweight people. Like other antihistamines, Periactin may make you feel sleepy and sluggish. However, some people, particularly children, may have the opposite reaction and become excited. How should you take Periactin? Follow your doctors directions for taking Periactin. If you miss a dose take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Do not take two doses at once. Store Periactin at room temperature in a tightly closed container. Are there any Periactin side effects? Periactin side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Periactin side effects may include anaphylaxis, anemia, appetite loss, chest congestion or tightness, chills, confusion, constipation, convulsions, diarrhea, difficulty urinating, dizziness, dry mouth, nose, or throat, earlier-than-expected menstrual period, exaggerated feeling of well-being, excessive perspiration, excitement, faintness, fatigue, fluttery or throbbing heartbeat, frequent urination, hallucinations, headache, hives, hysteria, inability to urinate, increased appetite and weight gain, insomnia, irritability, lack of coordination, light sensitivity, liver problems, low blood pressure, nausea, nervousness, rapid heartbeat, rash and swelling, restlessness, ringing in the ears, sleepiness, stomach pain, stuffy nose, tingling or pins and needles, tremor, vertigo, vision problems, vomiting, weight gain, wheezing, and yellow eyes and skin. Older people, in particular, are likely to become dizzy or drowsy, or develop low blood pressure in response to Periactin. What are the possible food and drug interactions when taking Periactin? If Periactin is taken with certain other drugs, the effects of either could be increased, decreased, or altered. Be sure to inform your doctor of all the prescription and over the counter medications you are taking. Avoid alcoholic beverages while taking Periactin. It is especially important to check with your doctor before combining Periactin with Antidepressant drugs classified as MAO inhibitors (including Nardil and Parnate), Sedatives (such as Nembutal and Seconal), or Tranquilizers (such as Librium and Valium). Are there any special warnings about Periactin? Like other antihistamines, Periactin may make you drowsy or impair your coordination. Be cautious about taking Periactin if you have bronchial asthma, the eye condition called glaucoma, an overactive thyroid gland, high blood pressure, heart disease, or circulatory problems. |
