Full information about Periactin

General Information on Periactin

Periactin is used to treat signs of allergies such as itching, runny nose, sneezing, watery eyes and other symptoms. It is also indicated in the treatment of hay fever caused by allergies (perennial allergic rhinitis) and seasonal allergic rhinitis.

Cyproheptadine Hydrochloride, the main active ingredient in the medication, is a sedating antihistamine. It blocks histamine H1 receptors in the body. Histamine is a natural substance produced by the body in response to allergies. It is known to cause release of other chemicals in the body that cause various symptoms of allergies. By preventing the bonding of histamine to its receptors, it stops the release of chemicals that cause allergy symptoms.

Periactin is available in the form of a tablet. Each Periactin tablet contains 4mg Cyproheptadine Hydrochloride. The drug is a prescription medication, so you can buy Periactin only if it is recommended by your doctor.

Side effects of Periactin

Periactin may cause mild to severe side effects in some people. Mild drowsiness, feeling restless or excited, tingling or numbness, blurred vision, nausea, appetite changes, upset stomach, constipation, dry mouth or nose, diarrhea, sleep problems, dizziness, increased urination or sweating, and a spinning sensation are some less severe side effects associated with the drug. These side effects generally wane over time. However, if they persist or become bothersome, you must consult your doctor.

Periactin may also cause serious side effects in some people. Feeling like you might pass out, dark-colored urine, confusion, fast or pounding heartbeat, hallucinations, ringing in your ears, fever, pale or yellowed skin, seizure, unusual behavior or thoughts, urinating less than usual or not at all, easy bleeding or bruising, or unusual weakness are some severe side effects associated with Periactin. Stop using the medication and consult your doctor immediately if you experience or notice any severe side effects after taking a dose of Periactin.

Periactin is listed as a pregnancy Category C drug. It is not known whether the drug passes into breast milk or how it may affect a nursing baby. Pregnant women and nursing mothers should exercise caution regarding the use of the drug. They should use Periactin only after learning about the benefits and risks associated with it.

Dosage of Periactin

Your doctor will give you specific instructions regarding the dosage. The dosage of Periactin is individualized. The recommended adult dosage is in the range of 4mg to 20mg daily. The anti-allergic effect of the medication remains for around 4 to 6 hours, so you would need to take around 3 doses daily.

Doctors generally start the treatment with an initial dose of one Periactin 4mg tablet three times daily. The dosage is adjusted as per the weight of the patient and response to therapy.


Periactin may potentially interact with other medicines you are using and cause side effects. It may interact with drugs such as sleeping tablets, barbiturates, antipsychotic medicines, Benzodiazepines, anticholinergic medicines for Parkinson's symptoms and urinary incontinence, strong opioid painkillers, tricyclic antidepressants, MAOI antidepressants, sedating antihistamines, or antispasmodics.

To reduce the risk of drug interactions, inform your doctor about every drug you are using before you buy Periactin. Before starting the treatment, provide a list of all the drugs you are taking to your doctor, which includes prescription medicines, over the counter drugs and herbal supplements.
