It is supplied as oral pills in two strengths-250 mg and 500 mg. Classified as an antimalarial agent, Aralen is primarily used for prophylaxis against malaria and for the treatment of acute malaria caused by chloroquine-sensitive Plasmodium species. The drug belongs to the 4-aminoquinoline class, which interferes with parasite metabolism and replication. ## Quick Reference Facts ``` **Active Ingredient** : Chloroquine **Form** : pill 250 mg | 500 mg **Primary Uses** : • Malaria prophylaxis • Treatment of chloroquine-sensitive malaria ``` ## What is Aralen? Aralen is a generic version of chloroquine phosphate tablets. It is marketed in many countries under brand names such as **Plaquenil** and **Aralen**. The medication is produced by licensed pharmaceutical manufacturers that comply with Good Manufacturing Practices (GMP). As a generic product, Aralen provides the same therapeutic effect as its branded counterparts while offering a lower cost to patients. ## How Aralen. Chloroquine works by entering the malaria parasite’s digestive vacuole and raising its pH. This neutralization prevents the parasite from digesting hemoglobin, an essential nutrient, leading to parasite death. The drug is rapidly absorbed from the gastrointestinal tract, reaching peak plasma concentrations within 2-4 hours. It is extensively distributed into tissues, including the liver, spleen, and retina, and is eliminated slowly-its terminal half-life ranges from 1 to 2 months, allowing weekly dosing for prophylaxis. Metabolism occurs primarily via hepatic pathways, with renal excretion of unchanged drug accounting for a smaller fraction. ## Conditions Treated with Arelen - **Malaria prophylaxis** - Aralen is taken before, during, and after travel to endemic regions to prevent infection by chloroquine-sensitive *Plasmodium* species. Weekly dosing maintains protective blood levels throughout exposure. - **Uncomplicated chloroquine-sensitive malaria** - For confirmed infections, a short course of higher-dose tablets eradicates the parasite and resolves fever and systemic symptoms. The regimen is timed to achieve rapid parasite clearance. ## Is Aralen the Right Medication for You? Aralen is most suitable for adults who: - Are traveling to areas where the malaria parasite remains sensitive to chloroquine. - Have been diagnosed with uncomplicated malaria caused by chloroquine-sensitive strains. - Do not have contraindications such as known hypersensitivity to 4-aminoquinolines, pre-existing retinal disease, or severe hepatic impairment. The medication may be less appropriate for: - Individuals with a history of cardiac conduction abnormalities, because chloroquine can prolong the QT interval. - Patients taking drugs that significantly raise chloroquine plasma levels (e.g., digoxin, certain macrolide antibiotics). - Pregnant or breastfeeding women unless the benefits clearly outweigh potential risks, as safety data are limited. Clinical judgment should balance disease severity, patient comorbidities, and local resistance patterns. ## Buying Aralen from [our online pharmacy](https://liabilis.com/order-aralen-online-en.html) ### Why Choose Our Service? Accessing antimalarial therapy can be challenging when travel plans are urgent or when insurance coverage does not include generic options. [our online pharmacy](https://liabilis.com/order-aralen-online-en.html) streamlines the process, offering a discreet, cost-effective way to obtain Aralen without compromising quality. ### Quality & Safety Assurance We partner with licensed international pharmacies to ensure quality and authenticity. Every batch of Aralen is sourced from manufacturers that meet stringent regulatory standards, and our pharmacy service verifies batch numbers against official pharmacopeial records, providing you with a trustworthy product. ### Pricing & Access Because Arelen is a generic formulation, it is priced near the manufacturer’s production cost-often 30-50 % lower than brand-name equivalents such as Plaquenil. This makes it an affordable choice for travelers, expatriates, and patients who need long-term prophylaxis. ### Discreet Delivery Orders shipped through our platform arrive in unmarked packaging, protecting your privacy. Express delivery typically reaches you within 7 days, while standard airmail arrives in approximately three weeks, giving you flexibility to suit your schedule. ## Use: Dosing, Missed Dose, Overdose - **Standard dosing for prophylaxis**: 250 mg (base) taken as a single tablet once weekly, starting 1-2 weeks before travel and continuing for 4 weeks after leaving the endemic area. - **Standard dosing for acute treatment**: 500 mg (base) at h, 6 h, 24 h, and 30 h (four doses total). Tablet strengths of 250 mg may be split to achieve the required dose. - **Missed dose**: If a prophylactic dose is missed, take the missed tablet as soon as remembered unless the next scheduled dose is less than 24 hours away; then skip the missed dose and resume the regular weekly schedule. Do not double-dose. - **Overdose**: Symptoms may include nausea, vomiting, visual disturbances, cardiac arrhythmias, and seizures. Seek emergency medical care immediately; supportive care and monitoring are essential. - **Practical precautions**: Take tablets with a full glass of water. Food does not markedly affect absorption, but antacids may reduce bioavailability-separate administration by at least 2 hours. Avoid alcohol, operating heavy machinery, or driving until you know how Arelen affects you. ## Safety Information ### ⚠️ Who Should Not Take Arelen - Individuals with known hypersensitivity to chloroquine or related 4-aminoquinolines. - Patients with documented retinal or visual field changes (chloroquine-induced retinopathy). - Persons with severe hepatic impairment (Child-Pugh class C). - Those with a history of serious cardiac arrhythmias or prolonged QT interval. ### Common Side Effects - Nausea, vomiting, and abdominal cramps (usually mild and transient). - Headache and dizziness. - Pruritus or mild rash. - Transient changes in taste. These effects are generally self-limiting; taking the medication with food may lessen gastrointestinal discomfort. ### Serious Side Effects (Seek Immediate Medical Help) - Visual disturbances (blurred vision, decreased acuity, color vision changes) that may herald retinal toxicity. - Cardiac arrhythmias, especially torsades de pointes, in patients with pre-existing QT prolongation. - Severe hypoglycemia, particularly in diabetic patients on insulin or sulfonylureas. - Hemolytic anemia in individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency. If any of these symptoms appear, discontinue Arelen and obtain urgent medical evaluation. ### Drug & Food Interactions - **Antacids** - Reduce chloroquine absorption; separate dosing by ≥2 hours. - **Digoxin** - Chloroquine may increase serum digoxin concentrations; monitor levels closely. - **Cyclosporine** - Co-administration can raise chloroquine levels, increasing toxicity risk. - **Macrolide antibiotics (e.g., erythromycin)** - May prolong QT interval when combined with chloroquine. - **Sulfonylureas/Insulin** - Heightened risk of hypoglycemia; adjust dose or increase glucose monitoring. ## Off-Label and Investigational Uses of Aralen - **COVID-19** - Early laboratory studies suggested antiviral activity, but large clinical trials have not demonstrated a clear benefit. Use remains experimental and is not FDA-approved. - **Rheumatoid arthritis and systemic lupus erythematosus** - Hydroxychloroquine, a close analogue, is approved for these conditions; chloroquine has been used off-label with limited evidence. Physicians may consider it in select cases, but safety and efficacy data are sparse. - **Amebiasis** - Some protocols combine chloroquine with metronidazole for intestinal amebiasis; this practice is based on small case series. *Off-label use should only be considered under the direct supervision of a qualified healthcare provider.* ## Storage & Handling - Keep tablets at room temperature (20-25 °C), protected from excess heat, moisture, and direct sunlight. - Store in the original container with a tight-closing lid. - Do not use after the printed expiration date; discard responsibly through a pharmacy take-back program. ## Frequently Asked Questions **Practical Use & Lifestyle** - **Can I travel with Aralen in my hand luggage?** Yes. Aralen tablets are allowed in carry-on bags for personal medical use. Keep them in their original packaging and have a copy of the prescription or a doctor’s note if requested by security personnel. - **Should I adjust the dosing schedule when crossing time zones?** For weekly prophylaxis, maintain the same 24-hour interval regardless of time-zone changes. If you miss a dose while traveling, follow the missed-dose guidance in the dosing section. - **Does alcohol affect the efficacy of Arelen?** Moderate alcohol consumption does not significantly alter chloroquine absorption, but excessive drinking can increase the risk of gastrointestinal upset and cardiac side effects. **Product & Formulation Details** - **What do Aralen tablets look like?** The 250 mg tablets are round, white, and bear the imprint “250 CHL.” The 500 mg tablets are larger, round, and imprinted “500 CHL.” In some regions, tablet color may vary slightly due to local manufacturing. - **Are there any inactive ingredients I should be aware of?** In addition to chloroquine phosphate, the tablets contain lactose, maize starch, and magnesium stearate. Patients with severe lactose intolerance should discuss alternatives with your prescriber. **Regulatory & Safety Nuances** - **Will Arelen appear on a standard drug test?** Routine workplace drug screens do not test for chloroquine. However, specialized toxicology panels used in some clinical settings can detect it if specifically requested. - **Is chloroquine safe for pregnant women?** Current data are limited; chloroquine crosses the placenta and animal studies have not shown teratogenicity, yet human safety data are insufficient. Use only if the potential benefit justifies the potential risk, under medical supervision. - **Can I use Arelen if I have G6PD deficiency?** Chloroquine can precipitate hemolysis in G6PD-deficient individuals, though the risk is lower than with primaquine. Screening before initiation is advisable. **Scientific & Clinical Curiosity** - **How long has chloroquine been used for malaria?** Chloroquine was first synthesized in the 193s and became the cornerstone of malaria treatment and prevention throughout the mid-20th century, dramatically reducing malaria mortality before resistance emerged. - **What is the half-life of chloroquine, and why does it matter?** The drug’s terminal half-life ranges from our service between 1 and 2 months, allowing weekly prophylactic dosing. However, the long half-life also means that side effects or toxic accumulation can persist for weeks after discontinuation. ## Glossary **Prophylaxis** : Preventive treatment intended to stop disease before it occurs. **Retinopathy** : Damage to the retina that can impair vision; chloroquine-induced retinopathy is dose- and duration-dependent. **Bioavailability** : The proportion of an administered dose that reaches systemic circulation in an active form. **Half-life** : The time required for the plasma concentration of a drug to decrease by half; influences dosing frequency. ## Disclaimer The information provided about **Aralen** is for general knowledge only.
