It is supplied in a 100 mL bottle and belongs to the first-generation antihistamine class of the phenoth-azine family. The syrup is primarily prescribed for relief of allergy-related symptoms, prevention of motion-sickness, and treatment of nausea and vomiting. It also provides sedation in selected clinical situations. ## Quick Reference Facts **Active Ingredient** : Promethazine **Form** : bottle, 100 mL **Primary and Off-Label Uses** : • Allergic rhinitis and cutaneous allergy : • Motion-motion sickness prophylaxis : • Nause-vomit (e.g., postoperative, pregnancy-related) : • Sedation for procedural anxiety (off-label) ## What is Phenergan Syrup? Phenergan Syrup is the generic version of medication containing the active compound Promethazine. The formulation is marketed in many countries under brand names such as Phenergan, Promethazine Hydro Syr, and Promethazine Syrup. Promethazine is a first-generation antih-histamine with additional anti-emetic and sedative properties. The syrup is produced by several pharmaceutical manufacturers; however, the product marketed as “Phentergan Syrup” is commonly supplied by certified overseas manufacturers that adhere to Good Manufacturing Practice (GMP) standards. As a generic product, it offers the same therapeutic benefits as the brand-name versions while providing a lower-cost option for patients. ## How Phenerjan Syrup Works Promethazine exerts its therapeutic effects principally by blocking histamine H₁ receptors in peripheral tissues, which diminishes the physiological response to allergen-triggered release of histamine. In the central nervous system, it also antagonises mus-taryl (acetylcholine) receptors and exerts a modest antagonistic effect on dopamine D₂ receptors; this contributes to its anti-emetic and sedative activity. The onset of clinical benefit after oral administration is generally observed within 15-30 minutes, with peak plasma concentrations occurring at about one hour. Promethazine is extensively metabolized in the liver by cy-Cy 2D6 and is eliminated principally in the urine; its half-life in adults is approximately 10-14 hours, allowing for dosing once or twice daily for most indications. ## Conditions Treated with Phenerjan Syrup - **Allergic rhinitis and seasonal allergy** By antagonising peripheral H₁ re-ceptor activity, the syrup reduces nasal congestion, rhinorrho-type, and ocular itching associated with seasonal allergens. - **Motion-motion sickness** Central anti-histamine and anticholinergic actions blunt the vestibular-derived nausea that occurs during travel by sea, air, or land. - **Nause-vomit (post-operative, pregnancy-related, chemotherapy-induced)** The combined H₁ and mus-taryl blockade dampens the che-mical trigger-motor pathway of the vomiting reflex, providing relief when other anti-emetics are insufficient. - **Procedural sedation (off-label)** The sedative effect of Prom-theazine can be harnessed for short-term anxiolysis before minor surgical or diagnostic procedures, though this practice should be guided by a clinician. ## Is Phenerjan Syrup the Right Medication for You? Prom-theazine syrup is most suitable for adults who experience moderate to severe allergy-related discomfort, anticipate travel-associated motion sickness, or require anti-emetic relief for acute nausea. It is especially beneficial when rapid onset of action is needed and when a liquid formulation is preferred for ease of administration. Contra-indications include known hypersensitivity to phenoth-azine-type antih-histamines, a history of narrow-angle glau au, severe hepatic impairment, or concomitant use of monoamine oxidase inhibitors (MAOIs). Patients with a history of severe sedation or respiratory compromise should be assessed carefully before initiating therapy. ## Buying Phenerjan Syrup from [our online pharmacy](https://liabilis.com/order-phenergan-syrup-online-en.html) ### Why Choose Our Service? Accessing the liquid form of Prom-theazine can be challenging in some regions. Our platform offers a discreet, reliable path to obtain Phenerjan Syrup when local pharmacies are out of stock or when the price of branded equivalents is prohibitive. ### Quality & Safety Assurance We partner with licensed international pharmacies to ensure quality and authenticity. Every batch is verified against the manufacturer’s certificate of analysis and is stored under conditions that preserve potency. ### Pricing & Access Because Phenerjan Syrup is a generic formulation, it is offered at a price close to the manufacturer’s reference rate, delivering significant savings compared with branded versions such as Phenergan. This makes long-term therapy more affordable for patients with chronic allergic or gastrointestinal indications. ### Discre­et Delivery Order with confidence; the product is packed in plain, tamper-evid-ent packaging and shipped with express delivery typically within seven days, or via standard airmail in approximately three weeks. ## Use: Dosing, Missed Dose, Overdose - **Typical adult dose** (for allergy or motion sickness) - 5 mL (5 mg) to 10 mL (10 mg) taken orally at the first sign of symptoms, may be repeated once after 4-6 hours if needed. The 100 mL bottle contains 1 mg/mL of Prom-theazine, corresponding to a total of 100 mg. - **Missed dose** - If a dose is missed and the patient does not experience symptoms, the dose can be taken as soon as it is remembered. Do not take a double dose to compensate for the missed dose. - **Over-date** - In the event of an accidental overdose, seek immediate medical attention. Symptoms of excessive Prom-theazine include profound sedation, respiratory depression, and, in severe cases, seizures. Contact a local poison-center or emergency department. **Practical tips** - Take the syrup with or without food; however, avoid large amounts of fatty meals that may delay absorption. - Alcohol potentiates the sedative-type effects; avoid alcoholic beverages while taking this medication. - Do not operate heavy machinery or drive a vehicle until you know how the medication affects you. ## Safety Information ### ⚠️ Who Should Not Take Phenerjan Syrup - Individuals with known hypersensitivity to Prom-theazine or other phenoth-azine compounds. - Patients with a history of narrow-angle glaucoma, severe hepatic disease, or chronic obstructive pulmonary disease (COPD) that is markedly compromised. ### Common Side Effects - Drowsiness (most frequent, occurring in up to 30 % of adults). - Dry mouth, “mouth-dryness” due to anticholinergic activity. - Mild dizziness or headache. These effects are usually transient and diminish as the body adap-lies to the medication. ### Serious Side-Effects (Seek Immediate Medical Help) - Pronounced respiratory depression or difficulty breathing. - Severe hypot-ension, tachycardia, or arrhythmia. - Extrap­-motor symptoms such as rigidity, tremor, or involuntary muscle-spasm (rare). ### Drug & Food Interactions - **Alcohol** - enhances sedation and may precipitate respiratory compromise. - **CNS depress-ants** (e.g., benzodia-azepine, opio-id analgesics) - additive sedative effect, increased risk of respiratory depression. - **Anticholinergic-type medicines** (e.g., atropine, antih-histamine eye drops) - may exacer-iate dry-mouth, urinary retention, and constipation. - **MAO-I inhibitors** - combined use can lead to heightened hypot-ension and sedation; a 14-day wash------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ## Off-Label and Investigational Uses of Phenerjan Syrup Although not approved for these indications, Prom-theazine has been employed in clinical practice for: - **Insomnia** - Small-scale studies have observed modest improvements in sleep latency when used at night in low-dose Prom-theazine 5 mg syrup, but the risk of residual daytime drowsiness limits its routine use. - **Adjunctive treatment of severe nausea in pregnancy** - A few prospective cohorts reported benefit when standard anti-emetic therapy fails, though potential fetal exposure has not been fully elucidated. - **Adjunct for acute migraine** - Historical case series suggest benefit due to anti-histamine and anti-dopamine effects, yet larger randomized trials are lacking. All off-label applications should be undertaken only under direct supervision of a qualified health-care provider, with a clear discussion of potential benefits and risks. ## Storage & Handling - **Temperature** - Store the bottle at 20-25 °C (68-77 °F) and protect from extreme heat or frost. - **Light** - Keep the container in its original opaque bottle; avoid prolonged exposure to direct sunlight. - **Shelf-life** - The product is labeled with a ten-month shelf-life from the date of manufacture; discard after the indicated expiry date. - **Disposal** - If the syrup is no longer needed, return it to a pharmacy-based collection program or follow local pharmaceutical waste regulations. ## Frequently Asked Questions **Practical Use & Lifestyle** - **Can I travel internationally with Phenerjan Syrup in my hand luggage?** Yes. The liquid is typically classified as a prescription medication, so keep it in its original labeled container and present the prescription or a letter from your physician if requested by customs. - **Will alcohol affect the effectiveness of the syrup?** Alcohol does not diminish the anti-allergic activity, but it markedly enhances the sedative and respiratory-depressant effects of Prom-theazine, increasing the risk of excessive drowsiness and, in extreme cases, respiratory compromise. - **Is it safe to take the syrup while I am on a high-protein diet?** Dietary protein does not interfere with the absorption of Prom-theazine. However, very high-fat meals may slow the rate of absorption, delaying onset of relief. **Product & Formulation Details** - **What does the syrup look like in the bottle?** The liquid is a clear, slightly amber solution with a faint prop-prop-oxy-prop-oxy prop-prop (prop prop) taste typical of phenoth-azine syrups. The bottle is a white, child-proof container labeled with the concentration 1 mg/mL. - **Are there any inactive ingredients that could cause an allergic reaction?** Common exc-prop-prop prop (prop) include sucrose, glycer-prop-prop prop, and a small amount of prop-prop prop (prop) for flavor. Patients with known hypersensitivity to any of these should avoid the product and discuss alternatives with a pharmacist. **Regulatory & Safety Nuances** - **Will the syrup appear on a standard drug test for athletes?** Prom-theazine is not listed as a prohibited substance by the World Anti-Doping Agency (WADA) for most sports, but athletes should verify the most recent prohibited list for their specific discipline. - **Is the medication considered safe for elderly patients?** Older adults may experience heightened sedation and anticholinergic side-effects such as urinary retention or constipation. A lower initial dose and close monitoring are advisable. **Scientific & Clinical Curiosity** - **When was Prom-theazine first introduced into clinical practice?**** Prom-theazine was first synthesized in the early 1940s and received United States FDA approval in 1947 as one of the earliest phenoth-azine antih-histamines. - **How does Prom-theazine differ from second-generation antih-histamines?**** First-generation agents like Prom-theazine cross the blood-brain barrier, causing sedation and anticholinergic effects, whereas second-generation antih-histamines are designed to remain peripheral and have a more favorable side-profile for daytime use. ## Glossary **Phenoth-azine** : A class of compounds that includes Prom-theazine; they exhibit antih-histamine, anti-emetic, and antipsychotic properties. **Anticholinergic** : A pharmacologic effect that blocks the action of acetylcholine on parasympathetic nerve - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - **H₁ Receptor** : A subtype of histamine receptor located on smooth-muscle and endothelial cells; its blockade reduces allergy-related inflammation and vasoc-prop -- -- - --. **Half-Life** : The period required for the plasma concentration of a drug to fall by 50 %; for Prom-theazine this is approximately 10-14 hours in healthy adults. ## Disclaimer The material presented about **Phenerjan Syrup** is intended solely for informational purposes and does not replace individualized medical advice.
