About Periactin
Allergy symptoms, excess histamine reactions, and a reduced appetite can significantly affect daily life. Generic Periactin (Cyproheptadine) is a first-generation antihistamine that also blocks serotonin receptors, making it useful both for allergy relief and as an appetite stimulant. In Singapore the medication is available by prescription, typically in a 4 mg oral tablet. It works by dampening the body’s histamine response while the antiserotonergic action can help increase food intake, especially in individuals struggling with weight loss or poor growth.
What is Generic Periactin (Cyproheptadine)?
Generic Periactin (Cyproheptadine) belongs to the first-generation H₁-antihistamine class. It was first approved in the United States in the -s and has since been adopted in many countries, including Singapore, where it is listed as a prescription-only medication. The active ingredient, cyproheptadine, is the same compound marketed under the brand name Periactin and several other trade names worldwide. As a generic, it offers the same therapeutic benefits as the branded product while typically being more affordable.
How Periactin Works
Cyproheptadine blocks H₁ histamine receptors, preventing histamine from binding and triggering the classic allergy cascade-itching, redness, and swelling. In addition to its antihistaminic action, the molecule antagonises 5-HT₂ serotonin receptors. By dampening serotonin signaling in the hypothalamus, the drug reduces the satiety signal that can suppress appetite, thereby promoting increased food intake. After oral administration, the tablet is rapidly absorbed, reaching peak plasma concentrations within 2-3 hours. It is metabolised primarily by the liver (CYP2D6 pathway) and eliminated through the kidneys with a half-life of roughly 8-12 hours, allowing once-daily dosing for most adults.
Why Periactin is Used for Allergy Relief, Appetite Stimulant Conditions
- Allergic Rhinitis & Urticaria - By blocking H₁ receptors, Periactin alleviates itching, sneezing, and hives that arise from airborne allergens or contact triggers.
- Dermatologic Itch - The antihistaminic effect reduces pruritus associated with eczema or drug-induced rashes, improving sleep and quality of life.
- Appetite Stimulation in Children - The antiserotonergic activity counters the appetite-suppressing effect of elevated serotonin, helping children with failure to thrive or adolescents with unexplained weight loss.
- Weight-Loss Management - In select adult patients experiencing reduced appetite due to chronic illness, Periactin can support nutritional intake while monitoring for side effects.
In clinical guidelines, cyproheptadine is considered a second-line option after non-sedating antihistamines for allergic symptoms, while its appetite-stimulating role remains a niche but evidence-supported indication.
Off-Label and Investigational Uses of Periactin
- Serotonin Syndrome - Small case series suggest cyproheptadine can mitigate severe serotonin toxicity by blocking 5-HT₂ receptors. It is not approved for this indication in Singapore and should only be used under specialist supervision.
- Migraine Prophylaxis - Early studies explored its preventive potential due to serotonergic antagonism, but larger trials have not confirmed consistent benefit.
- Nocturnal Enuresis - Some pediatric reports note reduced bedwetting episodes, though evidence is limited and the use remains off-label.
Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Periactin Right for You?
Periactin is most appropriate for individuals who experience pronounced allergy symptoms that have not responded adequately to non-sedating antihistamines, or for patients-particularly children-who need an appetite boost. It may be less suitable for those with a history of severe sedation, glaucoma, or urinary retention, as the anticholinergic component can exacerbate these conditions. Pregnant or breastfeeding women should discuss risks with their physician, as safety data are limited. Renal or hepatic impairment may require dose adjustments, and older adults often experience heightened drowsiness.
Taking Periactin Effectively
- Timing: Take the 4 mg tablet once daily, preferably in the evening to minimise daytime drowsiness.
- Food Interactions: The tablet can be taken with or without food; a light snack may reduce stomach upset.
- Alcohol: Avoid concurrent alcohol consumption, which can intensify sedation.
- Missed Dose: If a dose is missed, take it as soon as remembered unless it is near the time of the next dose-do not double up.
- Travel: Carry a copy of the prescription and keep the medication in its original container to satisfy customs regulations.
Understanding Side Effects and How to Manage Them
- Sedation: Drowsiness is the most common effect. Schedule the dose in the evening, and avoid driving or operating heavy machinery until you know how the drug affects you.
- Anticholinergic Symptoms: Dry mouth, constipation, and blurred vision may occur. Sip water regularly, incorporate fiber-rich foods, and consider a mild stool softener if constipation persists.
- Weight Gain: While appetite stimulation is a therapeutic goal, monitor weight changes to avoid excessive gain.
- Serious Reactions: Rarely, patients experience severe allergic reactions, cardiac arrhythmias, or pronounced hypotension. Seek immediate medical attention if you develop rash, swelling, chest pain, or faintness.

Frequently Asked Questions
-
Can I take Periactin with other antihistamines? Combining first-generation antihistamines can increase sedation and anticholinergic effects. It is best to avoid concurrent use unless directed by a physician.
-
How long does it take to see an appetite increase? Most patients notice a modest appetite boost within 3-5 days of consistent dosing, though individual responses vary.
-
Is Periactin safe for children under 2 years old? The medication is generally not recommended for infants younger than 2 years due to limited safety data and a higher risk of adverse effects.
-
Will Periactin affect my blood tests? Cyproheptadine does not typically interfere with routine laboratory parameters, but it can alter certain hepatic enzyme levels; your clinician may monitor liver function if you have pre-existing liver disease.
-
Can I consume grapefruit juice while taking Periactin? Grapefruit can affect CYP2D6 metabolism, potentially increasing cyproheptadine concentrations. It is prudent to limit grapefruit intake.
-
What should I do if I miss a dose? Take the missed tablet as soon as you remember, unless it is close to the time of your next scheduled dose-then skip the missed one and resume your regular schedule.
-
Is there a risk of dependence on Periactin for appetite stimulation? No evidence suggests physiological dependence; however, long-term use should be periodically reassessed by your healthcare provider.
-
Can Periactin be used to treat COVID-19 related loss of taste? There is currently no robust clinical evidence supporting its use for COVID-19 symptoms, so it remains an off-label consideration not endorsed by Singapore health authorities.
