Plaquenil (hydroxychloroquine sulfate) is a widely used prescription medication in the United States. It has been part of standard care for decades to help manage autoimmune conditions including rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), as well as certain types of cutaneous lupus. It is also used for malaria prophylaxis and treatment in accordance with public health guidance. In the U.S., Plaquenil is commonly dispensed as 200 mg tablets (equivalent to 155 mg base) and should be taken only under the supervision of a licensed healthcare provider.

As a disease-modifying antirheumatic drug (DMARD), Plaquenil is valued for its favorable long-term safety profile compared to other immunomodulators, its steroid-sparing effect in lupus, and its broad benefits on disease control and flares. Generic hydroxychloroquine is widely available, helping reduce costs for many patients. On this page you’ll find comprehensive information tailored to U.S. patients about indications, dosing strategies, contraindications, interactions, eye safety screening, pregnancy and breastfeeding considerations, and how to access Plaquenil through licensed U.S. pharmacies, including telehealth prescription support where appropriate.

Plaquenil cost in the USA

In the United States, hydroxychloroquine is available as both brand-name Plaquenil and as generic hydroxychloroquine sulfate. Generic versions typically offer substantial savings and are covered by many insurance plans. Out-of-pocket costs vary by pharmacy, insurance coverage, geographic location, and whether you use a savings program or coupon.

Typical cash prices for generic hydroxychloroquine can range from low-cost tiers (often under $20–$40 for a 30-day supply of 200 mg tablets at select pharmacies) to higher list prices at other locations without discounts. Brand-name Plaquenil is generally more expensive. Many patients reduce costs by:

• requesting generic hydroxychloroquine when clinically appropriate
• using a 90-day supply to lower per-tablet costs
• checking pharmacy discount programs, manufacturer copay cards (for brand), or prescription savings platforms
• using in-network pharmacies designated by their insurance plans

Always compare prices between pharmacies, and speak with your prescriber about whether generic hydroxychloroquine meets your clinical needs. The most cost-effective option depends on your dose, frequency, and coverage.

Where can I buy Plaquenil in the USA?

In the United States, Plaquenil is available by prescription only. You can obtain it from licensed retail and mail-order pharmacies. If you do not yet have a prescription, many U.S. telehealth services can connect you with a licensed clinician to review your medical history and determine whether Plaquenil is appropriate for you. Once a prescription is issued, it can be transmitted to a pharmacy of your choice for dispensing and delivery to your home.

Our partner platform helps you navigate legitimate U.S. pharmacy options and telehealth services, streamlining the process from consultation to fulfillment. We emphasize safe, compliant access: a U.S. prescription is required, and your clinician will determine the correct dosing and monitoring plan based on your condition.

For patients with autoimmune disease, consistent access and adherence are essential to prevent flares. If you’re new to Plaquenil, your care team may schedule baseline eye screening and periodic follow-up to ensure long-term safety. If you’re transferring care, ask your prescriber to send your prescription to a convenient, cost-effective U.S. pharmacy.

Plaquenil USA

Getting Plaquenil in the U.S. is straightforward when you work with licensed providers and pharmacies. After your clinician reviews your health status—including any heart rhythm history, other medications that may prolong QT interval, and existing retinal conditions—they will prescribe an individualized regimen, usually 200–400 mg per day for autoimmune indications, with adjustments based on body weight and clinical response.

What is hydroxychloroquine (Plaquenil)?

Plaquenil (hydroxychloroquine sulfate) is an antimalarial and immunomodulatory medication classified as a disease-modifying antirheumatic drug. It modulates immune pathways implicated in autoimmune conditions such as RA and SLE, and it is used for malaria prophylaxis and treatment in regions where chloroquine-sensitive malaria is present. Hydroxychloroquine is available in the U.S. as oral 200 mg tablets (155 mg base per tablet).

Key FDA-approved uses include:

• Rheumatoid arthritis (RA)
• Systemic lupus erythematosus (SLE) and chronic discoid (cutaneous) lupus
• Malaria prophylaxis and treatment (for chloroquine-sensitive strains, following current CDC guidance)

Beyond labeled uses, clinicians sometimes prescribe hydroxychloroquine off-label for select conditions based on clinical judgment. Off-label use should be individualized and supported by appropriate monitoring.

Plaquenil for Rheumatoid Arthritis

In RA, Plaquenil is commonly used as monotherapy in mild disease or in combination with other DMARDs (such as methotrexate or sulfasalazine) to enhance disease control. Benefits include reduced joint pain and swelling, improved function, and a favorable overall safety profile relative to many immunosuppressants.

Therapeutic effect is gradual; many patients begin to notice improvement within 4–12 weeks, with maximal benefit often taking several months. Because response builds over time, continuing therapy as directed by your rheumatologist is important before determining efficacy.

Typical dosing for adults with RA is 200–400 mg daily (once daily or divided), not exceeding approximately 5 mg/kg/day based on actual body weight, to minimize the risk of retinal toxicity. Dose adjustments may be necessary in renal impairment or based on tolerability. Your clinician will tailor dosing to your needs.

Plaquenil for Lupus (SLE and Cutaneous Lupus)

For patients with systemic lupus erythematosus, Plaquenil is foundational therapy that can reduce disease activity, decrease flare frequency, and allow lower doses of corticosteroids. It is also beneficial for cutaneous lupus (chronic discoid lupus) to help control skin manifestations. In SLE, long-term use is common and associated with improved outcomes, including potential cardiovascular benefits and reduced thrombotic events in some populations.

Standard dosing is 200–400 mg daily. Because lupus is chronic and relapsing, continuation is often recommended unless contraindications arise. Stopping therapy without medical guidance can lead to flares, so always work closely with your rheumatology team.

Plaquenil for Malaria: Prevention and Treatment

Plaquenil may be used for malaria prophylaxis and treatment in areas where Plasmodium species remain sensitive to chloroquine-class drugs. In the United States, your clinician will reference up-to-date CDC travel health recommendations to determine whether hydroxychloroquine is suitable for your itinerary.

General principles for malaria prophylaxis include:

• starting prophylaxis prior to travel (often 1–2 weeks before), continuing during the stay, and for 4 weeks after leaving the endemic area
• taking the weekly dose with food at the same time each week to improve tolerability
• using repellents, bed nets, and protective clothing; no antimalarial is 100% effective

For malaria treatment, dosing follows established guidelines and differs from prophylaxis. Because treatment regimens depend on species, region, severity, and resistance patterns, you should seek prompt medical evaluation for fever or symptoms during or after travel. Never self-treat suspected malaria without medical supervision.

How Plaquenil works (mechanism of action)

Hydroxychloroquine exerts antimalarial effects by accumulating in parasite lysosomes and interfering with heme detoxification, which is toxic to the parasite. In autoimmune disease, it has several proposed mechanisms:

• modulation of toll-like receptor (TLR) signaling and antigen presentation
• inhibition of lysosomal activity and autophagy-related processes within immune cells
• reduction of pro-inflammatory cytokine release

These immunomodulatory actions help downregulate overactive immune responses characteristic of RA and SLE.

Safety, monitoring, and eye screening in the USA

Hydroxychloroquine has an established safety record when used at appropriate doses with recommended monitoring. The most important long-term risk is retinal toxicity, which can impair vision if not detected early. Risk increases with higher daily doses (generally above 5 mg/kg/day of actual body weight), long duration of use (typically >5 years), renal impairment, concurrent tamoxifen use, and certain pre-existing retinal conditions.

U.S. guidance typically recommends:

• baseline eye evaluation within the first year of starting Plaquenil, including appropriate retinal imaging when available
• annual screening after 5 years of use, or earlier/more frequent screening in higher-risk individuals
• dose optimization using actual body weight to reduce risk

Other monitoring considerations include periodic assessment of blood counts, liver and kidney function as clinically indicated, and evaluation for muscle weakness or cardiomyopathy rarely associated with long-term use.

Common side effects of Plaquenil

Many people tolerate hydroxychloroquine well. When side effects occur, they are often mild and transient. Common effects may include:

• nausea, stomach upset, abdominal pain
• loss of appetite, diarrhea
• headache, dizziness
• skin rash or itching, photosensitivity
• changes in skin pigmentation or hair discoloration (rare)

Serious but uncommon adverse events include:

• retinal toxicity/vision changes
• heart rhythm changes (QT prolongation), cardiomyopathy (rare)
• severe hypoglycemia (with or without diabetes medications)
• myopathy or neuromyopathy (rare)
• severe skin reactions (extremely rare)

Seek urgent medical care if you experience vision changes, fainting, palpitations, severe rash, difficulty breathing, or signs of very low blood sugar (confusion, sweating, shakiness). Report any suspected side effects to your clinician or the FDA MedWatch program.

How to take Plaquenil

To improve tolerability, take hydroxychloroquine with food or milk. Swallow tablets whole with water. Follow your prescriber’s instructions exactly; do not change your dose without medical guidance. For autoimmune conditions, benefits build gradually—do not stop early unless you’re instructed to do so. If you miss a dose, take it when you remember unless it is close to your next dose; never double up.

For malaria prophylaxis, take the medication on the schedule provided by your travel clinic or clinician. If you vomit soon after a dose, contact your clinician for advice, as you may need to repeat the dose.

Hydroxychloroquine and COVID-19: current U.S. guidance

Large, well-conducted studies and U.S. public health agencies (including the FDA and NIH) do not recommend hydroxychloroquine for the prevention or treatment of COVID-19 outside clinical trials. Early emergency authorizations were revoked, and current treatment guidelines advise against routine use for COVID-19. If you have questions about COVID-19 care, speak with your healthcare provider about evidence-based options.

Dosing overview (adults)

Dosing varies by indication, body weight, and clinical response. Always follow your prescriber’s instructions.

Rheumatoid arthritis

Typical total daily dose: 200–400 mg (once daily or divided). Do not exceed approximately 5 mg/kg/day actual body weight unless your clinician determines a different plan is necessary. Therapeutic effect may take several weeks to months.

Systemic and cutaneous lupus

Typical total daily dose: 200–400 mg. Long-term therapy is common. Dose adjustments are individualized, especially for renal impairment and risk reduction of retinopathy.

Malaria prophylaxis

Weekly dosing is commonly used in sensitive regions. Start prior to travel, continue during exposure, and for 4 weeks after leaving. Your travel medicine provider will tailor a plan based on your destination and health status.

Malaria treatment

Treatment regimens differ from prophylaxis and depend on species, region, severity, and resistance patterns. Urgent clinical evaluation is required for suspected malaria; do not self-treat.

Drug interactions

Tell your healthcare providers and pharmacist about all prescription and OTC medicines, vitamins, and herbal supplements you take. Notable potential interactions include:

• QT-prolonging drugs (e.g., certain antiarrhythmics like amiodarone; some macrolide antibiotics; some antipsychotics): additive risk of heart rhythm changes
• digoxin: hydroxychloroquine may increase digoxin levels; monitoring may be needed
• antidiabetic agents and insulin: increased risk of hypoglycemia
• antacids and kaolin: may reduce absorption—separate doses by several hours
• cimetidine: may affect hydroxychloroquine metabolism
• mefloquine or other seizure-threshold–lowering agents: increased seizure risk
• tamoxifen: increased risk of retinal toxicity

This list is not exhaustive. Your clinician may monitor EKGs, adjust doses, or choose alternatives depending on your medication profile and comorbidities.

Who should not take Plaquenil?

Plaquenil is not appropriate for everyone. Contraindications and cautions include:

• known hypersensitivity to hydroxychloroquine or chloroquine
• pre-existing retinal or visual field changes attributable to 4-aminoquinoline compounds
• risk factors for QT prolongation without proper monitoring
• severe hepatic or renal disease without dose adjustment and close supervision
• psoriasis or porphyria (may exacerbate)

Before starting Plaquenil, review your medical history (including heart rhythm issues, eye conditions, kidney or liver problems) and medication list with your clinician.

Pregnancy and breastfeeding

In many cases, continuing hydroxychloroquine during pregnancy is recommended for patients with SLE due to benefits in disease control and maternal-fetal outcomes. However, decisions are individualized—always consult your obstetrician and rheumatologist. Hydroxychloroquine is excreted in breast milk in small amounts; discuss breastfeeding plans with your clinician to weigh benefits and risks based on your clinical status.

Pharmacist’s tips for taking Plaquenil

Consider these U.S.-focused best practices:

• take with food or milk to reduce nausea
• use consistent daily timing to support adherence
• schedule baseline and periodic eye exams as directed
• use sun protection if you notice photosensitivity
• do not exceed your prescribed dose; higher daily doses increase eye risk
• separate antacids and Plaquenil doses by several hours to avoid reduced absorption
• if you take warfarin, digoxin, or QT-prolonging drugs, notify your prescriber for appropriate monitoring

Side effects by use case

While side effects are not typically dependent on indication, patients may report different experiences:

Rheumatoid arthritis or lupus

• GI upset (nausea, abdominal discomfort), especially at initiation
• headache or dizziness
• skin rash or itching
• rare: visual changes (report promptly), very low blood sugar symptoms, muscle weakness

Malaria prophylaxis/treatment

• nausea, abdominal cramps, diarrhea
• headache, dizziness
• rare: pruritus, visual changes, mood changes

If you experience signs of an allergic reaction (hives, swelling, difficulty breathing), seek emergency care. Report persistent or severe adverse effects to your healthcare provider.

Storage, missed doses, and overdose

Store Plaquenil at room temperature away from moisture and light. Keep out of reach of children and pets—small amounts can be dangerous if accidentally ingested by children. If you miss a dose, take it when remembered unless it is close to the next scheduled dose; do not double up. In case of overdose, seek immediate medical attention or contact Poison Control (1-800-222-1222 in the U.S.).

Evidence and clinical guidance

Hydroxychloroquine’s role in RA and SLE is supported by decades of clinical experience and research. It is a mainstay of lupus care due to its broad benefits and relatively favorable safety when monitored appropriately. For malaria, its utility depends on local resistance patterns; the CDC provides current recommendations for travelers and clinicians. For COVID-19, major U.S. guidelines recommend against routine use outside clinical trials.

Insurance, access, and affordability in the USA

Most U.S. insurers cover generic hydroxychloroquine; copays vary by plan. If you face high out-of-pocket costs, ask about:

• generic substitution when clinically appropriate
• 90-day fills via mail-order to reduce costs
• pharmacy discount programs and coupons
• manufacturer copay support (for brand Plaquenil) if eligible

Our partner platform can coordinate with prescribers and pharmacies to streamline access, including shipment to your U.S. address when permitted.

Recommendations from our specialists

For autoimmune conditions, consistency is key. Our clinical advisors recommend staying adherent to your prescribed Plaquenil regimen, attending scheduled eye exams, and notifying your care team promptly about any visual symptoms, palpitations, or severe hypoglycemia signs. If you are planning international travel to malaria-endemic regions, arrange a travel medicine consult early to confirm whether hydroxychloroquine is appropriate for your destination and to set up prophylaxis on time.
