Geriatric Use

Clinical studies of Pronicy HCl tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy (see WARNINGS, Activities Requiring Mental Alertness).



Each tablet contains 4 mg of Pronicy hydrochloride.

How should this medicine be used?

Medically reviewed by Last updated on Jun 1, 2019.


Pronicy (Periactin) is an antihistamine used to treat allergic reactions by blocking the histamines. The drug is used for various types of allergic reactions including skin reactions. Off-label (non-FDA approved) uses include spasticity associated with spinal cord injury and preventing migraine headaches. Review side effects, dosage, drug and supplement interactions, and pregnancy and breastfeeding safety information prior to taking this drug. Periactin, the brand name, has been discontinued.

Why is this medication prescribed?

Pronicy relieves red, irritated, itchy, watery eyes; sneezing; and runny nose caused by allergies, irritants in the air, and hay fever. It may also be used to relieve the itching of allergic skin conditions, and to treat hives, including hives caused by exposure to cold temperatures and by rubbing the skin. Pronicy is also sometimes used to treat allergic reactions in people who have received blood products as part of medical treatment and to treat life-threatening allergic reactions after the symptoms have been brought under control with other medications. Pronicy will help relieve symptoms but will not treat the cause of symptoms or speed recovery. Pronicy is in a class of medications called antihistamines. It works by blocking the action of histamine, a substance in the body that causes allergic symptoms.

Pronicy (Periactin)

Pronicy (Periactin), an antagonist at the 5-HT 2, histamine H1, L-calcium channels and muscarinic cholinergic receptors, is widely used in the preventive treatment of childhood migraine ( Barlow, 1984; Forsythe and Hockaday, 1988 ; Raskin, 1988b ). Curran and Lance (1964) found Pronicy to be more effective than placebo but less effective than methysergide. Pronicy (Periactin) is available as 4-mg tablets. The total dose ranges from 12 to 36 mg a day (given twice to three times a day or at bedtime). Common adverse events are sedation and weight gain; dry mouth, nausea, lightheadedness, ankle edema, aching legs, and diarrhea are less common. Pronicy may inhibit growth in children ( Smyth and Lazarus, 1974 ) and reverse the effects of SSRIs. Rao and colleagues (2000) reported that Pronicy (4 mg/day) was as effective as propranolol (80 mg/day) in reducing migraine frequency and severity. The combination of Pronicy and propranolol was more effective than monotherapy.

What is Pronicy, and how does it work (mechanism of action)?

Pronicy (Periactin) is an oral antihistamine used for treating allergic reactions. It works by blocking the effects of histamine and is classified as a first generation antihistamine. Histamine is released by cells of the body during several types of allergic reactions and, to a lesser extent, during some viral infections, such as the common cold. When the histamine binds to receptors on other cells, it stimulates changes within the cells that lead to the release of chemicals that cause sneezing, itching, and increased production of mucus. Antihistamines compete with histamine for cell receptors and bind to the receptors without stimulating the cells. In addition, they prevent histamine from binding and stimulating the cells. Pronicy also blocks the action of acetylcholine (anticholinergic effect) and serotonin, two neurotransmitters that nerves and muscles use to communicate with one another, and it causes drowsiness.

How should I take Pronicy (Periactin)?

Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Do not give this medicine to a child younger than 2 years old. You should not use antihistamine medication to make a child sleepy. Death can occur from the misuse of an antihistamine in very young children.

Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

Tell your doctor if you have any changes in weight. Pronicy doses are based on weight (especially in children and teenagers), and any changes may affect the dose.

This medicine can cause you to have a false positive drug screening test. If you provide a urine sample for drug screening, tell the laboratory staff that you are taking Pronicy.

Store in a tightly-closed container at room temperature, away from moisture and heat.
