It is supplied as a 4 mg oral tablet and belongs to the class of first-generation H₁-receptor antagonists with additional antiserotonergic activity. The primary therapeutic uses of Periactin are relief of allergic symptoms such as rhinitis and urticaria, and stimulation of appetite in individuals with marked loss of desire to eat. Secondary, off-label applications-such as treatment of serotonin syndrome-are sometimes reported in clinical practice, but these uses are not approved by major regulatory agencies. ## Quick Reference Facts **Active Ingredient** : Cyproheptadine **Form** : pill 4 mg **Primary Uses** : • Relief of allergic rhinitis and urticaria • Management of pruritus associated with allergic conditions • Appetite stimulation in patients with severe anorexia ## What is Periactin? Periactin is the generic formulation that contains the active compound cyproheptadine. It is the generic version of medications containing cyproheptadine. Marketed under brand names such as Periactin, Cyprohept, and other regional equivalents, this product offers the same pharmacological profile as its brand-name counterparts. First-generation antihistamines like cyproheptadine were developed in the mid-20th century; the compound is chemically a dibenzocycloheptene derivative that blocks H₁-histamine receptors and antagonizes serotonin (5-HT₂) receptors. Periactin is produced by multiple manufacturers for international distribution and is classified as a prescription medication in most jurisdictions. ## How Periactin Works Cyproheptadine exerts its therapeutic effect through two principal mechanisms. First, it binds competitively to peripheral H₁-histamine receptors, preventing histamine-induced vasodilation, increased vascular permeability, and sensory nerve activation that underlie itching, sneezing, and rhinorrhea. Second, its antagonism of central 5-HT₂ receptors reduces serotonergic stimulation of the appetite-regulating centers in the hypothalamus, thereby increasing food intake. The drug is well absorbed after oral administration, reaching peak plasma concentrations within 1-2 hours. It is extensively metabolized in the liver via CYP2D6 and eliminated primarily in the urine with a terminal half-life of approximately 8 hours, supporting two to three daily dosing intervals. ## Conditions Treated with Periactin - **Allergic rhinitis** - By blocking H₁ receptors in the nasal mucosa, Periactin alleviates sneezing, itching, and nasal discharge associated with seasonal or perennial allergies. - **Chronic urticaria** - Histamine release from mast cells drives wheal formation; antihistamine action reduces the size and number of hives and relieves associated pruritus. - **Pruritus of allergic origin** - Peripheral H₁ blockade diminishes the itch sensation that can accompany dermatoses such as atopic dermatitis or insect bites. - **Appetite stimulation** - Antagonism of central 5-HT₂ receptors diminishes serotonergic satiety signals, leading to increased caloric intake in patients with anorexia, cancer-related cachexia, or other conditions causing severe loss of appetite. ## Is Periactin the Right Medication for You? Periactin is most appropriate for adults who experience bothersome allergic symptoms that have not responded adequately to second-generation antihistamines, or for individuals whose medical condition involves clinically significant loss of appetite. It is particularly useful when both antihistamine and appetite-stimulating effects are desired in a single agent. Contraindications include known hypersensitivity to cyproheptadine or any component of the tablet, narrow-angle glaucoma, and severe hepatic impairment. Caution is advised in patients with asthma, urinary retention, or a history of cardiac arrhythmias, as anticholinergic and serotonergic activities may exacerbate these conditions. Pregnant or breastfeeding women should discuss risks with their health professional because safety data are limited. ## Buying Periactin from [our online pharmacy](https://liabilis.com/order-periactin-online-en.html) ### Why Choose Our Service?

Dosage may be adjusted based on therapeutic response and tolerability. - **Missed dose**: If a dose is forgotten and the scheduled time is less than 6 hours away, take the missed tablet as soon as remembered. If the next dose is imminent, skip the missed tablet and resume the regular schedule. Do not double-dose. - **Overdose**: Symptoms may include excessive drowsiness, rapid heart rate, dry mouth, and blurred vision. In the event of suspected overdose, seek immediate medical attention or contact a poison control center. - **Administration advice**: Alcohol and other central nervous system depressants can amplify sedation; avoid operating heavy machinery until you know how Periactin affects you. Taking the tablet with a full glass of water is recommended. ## Safety Information ### ⚠️ Who Should Not Take Periactin - Documented hypersensitivity to cyproheptadine or any excipients. - Narrow-angle or closed-angle glaucoma. - Severe hepatic impairment (Cytochrome P450 metabolism may be compromised). - Infants and children under 12 years unless prescribed by a pediatric specialist. ### Common Side Effects - **Drowsiness** (most frequent; may diminish with continued use). - **Dry mouth, constipation, or blurred vision** due to anticholinergic properties. - **Increased appetite and modest weight gain**; usually desired in the indicated population. - **Mild dizziness**; advise caution when standing quickly. ### Serious Side Effects (Seek Immediate Medical Help) - **Palpitations, irregular heart rhythm, or severe hypotension**. - **Severe allergic reaction** (rash, swelling, difficulty breathing). - **Marked confusion or hallucinations**, especially in the elderly. - **Signs of serotonin syndrome** (agitation, hyperthermia, tremor) when combined with other serotonergic agents. ### Drug & Food Interactions - **CNS depressants (benzodiazepines, opioids, alcohol)** - additive sedation; limit concurrent use. - **Other anticholinergic drugs (e.g., trihexyphenidyl, atropine)** - may increase dry-mouth and constipation risk. - **Serotonergic agents (SSRIs, MAO inhibitors, tramadol)** - potential for serotonin syndrome; monitor closely. - **Warfarin** - limited data suggest possible enhancement of anticoagulant effect; periodic INR assessment recommended when co-administered. ## Off-Label and Investigational Uses of Periactin - **Serotonin syndrome** - Clinical case series have reported that cyproheptadine can reverse symptoms of excess serotonergic activity, such as agitation and hyperreflexia, when conventional measures are insufficient. This use remains off-label and should be supervised by a specialist. - **Migraine prophylaxis** - Small studies indicate that the antiserotonergic action may reduce migraine frequency, but evidence is insufficient for formal approval. - **Dermatologic pruritus not related to allergies** - Cyproheptadine has been employed in refractory itching conditions (e.g., cholestatic pruritus) with variable success. All off-label applications must be undertaken only under the direct oversight of a qualified healthcare provider. ## Storage & Handling - Store tablets at 20-25 °C (68-77 °F) in a dry place, protected from moisture and direct sunlight. - Keep the container tightly closed and out of reach of children. - Do not use the medication after the printed expiration date. - Dispose of unused tablets through a pharmacy take-back program or according to local hazardous waste regulations. ## Frequently Asked Questions **Practical Use & Lifestyle** - **Can I travel internationally with Periactin?** Yes, but keep the medication in its original packaging with a copy of the prescription or a physician’s note, as some countries require documentation for import of prescription drugs. - **Is it safe to take Periactin with caffeine?** Caffeine does not have a known pharmacologic interaction with cyproheptadine, but excessive caffeine may counteract the sedative effect, potentially reducing the medication’s benefit for allergy relief. **Product & Formulation Details** - **What do Periactin tablets look like?** Periactin tablets are typically round, white to off-white, scored for optional splitting, and bear the imprint “4 mg”. Tablet appearance may vary slightly between manufacturers. - **Can I split a 4 mg tablet?** The tablet is scored, allowing division into two 2 mg portions if a lower dose is clinically indicated. Always confirm dose adjustments with a pharmacist or prescriber. **Regulatory & Safety Nuances** - **Will Periactin show up on a drug test?** Cyproheptadine is not a controlled substance and is not screened for in standard occupational drug-testing panels. - **Is Periactin safe for athletes subject to anti-doping regulations?** The World Anti-Doping Agency does not list cyproheptadine as a prohibited substance, but athletes should verify with their governing body, especially if competing in sports with strict medication disclosure policies. **Scientific & Clinical Curiosity** - **What was the original purpose of developing cyproheptadine?** It was synthesized in the 196s as a potent H₁-antagonist intended for allergic conditions, with the added benefit of appetite stimulation discovered later. - **How does Periactin compare to second-generation antihistamines?** Compared with newer agents, Periactin is more likely to cause sedation and anticholinergic effects due to its ability to cross the blood-brain barrier, but it also offers the unique benefit of appetite stimulation. **Additional Practical Questions** - **Can Periactin be taken on an empty stomach?** Yes, the tablet may be taken with or without food; however, taking it with a meal can lessen occasional stomach irritation. - **Do I need to avoid dairy products while on Periactin?** No specific interaction with calcium-rich foods has been documented, so dairy does not need to be restricted. - **Is there a risk of dependence on Periactin?** Cyproheptadine does not produce craving or tolerance typical of controlled substances; however, abrupt discontinuation after prolonged high-dose use may result in rebound itching. - **How long does it take to notice an effect on appetite?** Increased hunger can be observed within a few days of consistent dosing, though maximal effect may require up to two weeks. ## Glossary **Antihistamine** : A drug that blocks histamine receptors, reducing allergic symptoms such as itching, swelling, and runny nose. **Antiserotonergic** : Refers to a substance that inhibits the action of serotonin at its receptors, often influencing mood, appetite, and gastrointestinal function. **First-generation H₁ antagonist** : An older class of antihistamines that readily enters the central nervous system, commonly causing sedation. **GMP (Good Manufacturing Practice)** : International quality standards that ensure pharmaceutical products are consistently produced and controlled. **Half-life** : The time required for the plasma concentration of a drug to decrease by 50 % after reaching steady state. ## Disclaimer The information provided about **Periactin** is for general knowledge only.
