ERIG Vaccine Price Philippines 2026: Cost, Free Options & PhilHealth
Quick answer: ERIG (equine rabies immunoglobulin) costs approximately ₱1,800 to ₱2,160 per vial in selected Philippine pharmacy listings. At private animal-bite clinics, published ERIG charges start at around ₱1,500 to ₱1,800, depending on whether the facility charges per infiltration, vial, or treatment. The total can be higher depending on the amount required and additional services. Some government Animal Bite Treatment Centers (ABTCs) provide ERIG free of charge, while PhilHealth offers a ₱5,850 Animal Bite Treatment Package at accredited providers.
When it is used: ERIG provides ready-made antibodies to help prevent rabies after certain high-risk animal bites, scratches, or saliva exposures. It is mainly used for Category III exposures, including bites that penetrate the skin and saliva contacting broken skin or the eyes, nose, or mouth. ERIG provides immediate antibodies while the anti-rabies vaccine stimulates the body’s immune response. It is generally administered once during post-exposure treatment when indicated, rather than as a routine vaccine or booster.
ERIG Prices in the Philippines
The following table compares publicly advertised medicine prices, private clinic rates, and government treatment options.
| Where You Get ERIG | Published Price | Important Note |
|---|---|---|
| Government Animal Bite Treatment Center | Free at selected facilities | Depends on eligibility and medicine availability |
| RAC Animal Bite Clinic, Pasig | ₱1,500 per infiltration | Also advertises ₱1,800 per 20 kg |
| CIF Central Animal Bite Center, Quezon City | ₱1,700 per vial | Advertised Equirab rate |
| Pallad Health, Batangas | Starts at ₱1,800 | Private clinic starting price |
| Southstar Drug | ₱1,800 per vial | Equirab pharmacy listing; availability must be checked |
| THOG Pharmacy | ₱2,160 per vial | Vinrab 1,000 IU/5 mL; listed as sold out when checked |
| PhilHealth-accredited ABT provider | ₱5,850 package benefit | Not a retail ERIG price |
Important: These are selected published rates, not a nationwide average. A pharmacy vial price, a per-infiltration charge, and a clinic’s starting price cannot be compared as though they include the same services.
The amount you pay may also include consultation, rabies vaccination, wound care, and other medically necessary treatment.
How Much ERIG Do You Need Based on Body Weight?
ERIG dosing is calculated using body weight, but the amount actually administered also depends on the wounds. The maximum recommended dose of equine rabies immunoglobulin is 40 international units (IU) per kilogram of body weight.
A commonly listed ERIG product contains 200 IU/mL, equivalent to 1,000 IU in a 5 mL vial.
ERIG Maximum Dose and Illustrative Cost by Weight
This table shows the calculated maximum dose and the theoretical cost of purchasing enough complete 1,000 IU vials at a retail price of ₱2,160 each.
| Body Weight | Maximum Dose | Whole Vials to Supply Maximum | Illustrative Medicine Cost |
|---|---|---|---|
| 20 kg | 800 IU | 1 | ₱2,160 |
| 25 kg | 1,000 IU | 1 | ₱2,160 |
| 40 kg | 1,600 IU | 2 | ₱4,320 |
| 50 kg | 2,000 IU | 2 | ₱4,320 |
| 60 kg | 2,400 IU | 3 | ₱6,480 |
| 75 kg | 3,000 IU | 3 | ₱6,480 |
| 80 kg | 3,200 IU | 4 | ₱8,640 |
These are mathematical examples, not actual clinic quotations or recommended injection amounts. The table assumes complete vials are purchased to supply the calculated maximum. It excludes consultation, vaccine, administration, and other treatment charges.
Does a 60 kg Patient Always Need Three Vials?
No. A 60 kg patient has a calculated ERIG maximum of 2,400 IU. However, current WHO guidance emphasizes infiltrating rabies immunoglobulin into and around the exposed wounds, up to the maximum calculated dose.
The amount actually required may be lower. The clinic’s billing method also matters. Some providers charge per vial, while others charge per infiltration or weight category.
A patient should therefore not assume that the maximum-dose calculation equals the amount that must be purchased or paid. Before treatment, ask whether the quotation covers all the ERIG required for the wounds.
ERIG Prices at Private Animal Bite Clinics
Several private clinics in the Philippines publish ERIG charges, although their pricing methods differ.
| Clinic | Location | Published ERIG Price |
|---|---|---|
| CIF Central Animal Bite Center | Loyola Heights, Quezon City | ₱1,700 per vial |
| RAC Animal Bite Clinic | Manggahan, Pasig City | ₱1,500 per infiltration or ₱1,800 per 20 kg |
| Pallad Health | Lipa City, Batangas | Starts at ₱1,800 |
CIF Central Animal Bite Center
CIF’s published 2026 advertisements include an Equirab price of ₱1,700 per vial. The clinic also advertises separate charges for first-visit vaccination packages and succeeding anti-rabies vaccine doses. Ask whether consultation, wound care, and administration are included in the final quotation.
RAC Animal Bite Clinic
RAC’s publicly advertised rates include:
- ERIG infiltration: ₱1,500
- Weight-related ERIG rate: ₱1,800 per 20 kg
These are different charging methods. Patients should confirm which applies and whether the price covers all required treatment.
Pallad Health
Pallad Health publishes ERIG starting at ₱1,800. Its separate clinic prices include:
| Service | Published Price |
|---|---|
| ERIG | Starts at ₱1,800 |
| Anti-rabies vaccine | ₱650 per dose |
| Intramuscular anti-rabies vaccine | ₱1,300 |
| Consultation | ₱400 |
| Wound care | ₱100 |
| Tetanus toxoid | ₱200 |
| Tetanus toxoid promotional price | ₱150 |
The starting ERIG price does not necessarily cover every patient’s required amount. These clinic examples demonstrate why the lowest advertised injection price may not equal the final bill.
ERIG Pharmacy Prices by Brand
ERIG is available under different product names, including Equirab and Vinrab.
| Pharmacy or Supplier | Product | Listed Price | Notes |
|---|---|---|---|
| Southstar Drug | Equirab, 5 mL | ₱1,800 | Availability requires confirmation |
| THOG Pharmacy | Vinrab, 1,000 IU/5 mL | ₱2,160 | Product page listed sold out |
| BrixMp | Vinrab, pack of 10 vials | ₱16,500 per pack | Bulk supplier price |
BrixMp’s pack price works out to ₱1,650 per vial when purchasing all ten vials. This should not be treated as a verified single-vial retail price. Pharmacy prices cover the medicine, not necessarily professional administration.
ERIG requires proper handling, storage, and medical assessment. A pharmacy purchase does not replace treatment at an Animal Bite Treatment Center. If considering purchasing ERIG separately, confirm with the treating facility first. Some clinics may not accept patient-supplied medicines.
Where Can You Get Free ERIG in the Philippines?
Some government Animal Bite Treatment Centers provide rabies immunoglobulin free of charge. These centers may also offer rabies vaccination, tetanus prevention, wound care, and patient counseling.
However, not every government facility has the same services, eligibility requirements, or medicine supply.
Davao Regional Medical Center
Davao Regional Medical Center’s Animal Bite Treatment Center lists free post-exposure services, including:
- Anti-rabies vaccination
- Rabies immune globulin
- Tetanus vaccination
- Wound dressing
- Patient education and counseling
Its published schedule is Monday to Friday, excluding holidays, from 8:00 AM to 5:00 PM. This is an example of a public hospital advertising free rabies immunoglobulin services, not a guarantee that every public facility provides ERIG free.
How to Find a Government Animal Bite Center
If you need rabies post-exposure treatment, contact or visit:
- Your nearest government hospital or emergency department.
- Your City or Municipal Health Office.
- A DOH-recognized Animal Bite Treatment Center.
- A PhilHealth-accredited Animal Bite Treatment Package provider.
You can consult PhilHealth’s accredited healthcare facilities directory to identify participating providers. Ask whether ERIG is available, whether treatment is free or subsidized, and whether the center can provide treatment promptly.
Do not delay rabies assessment while looking for free ERIG. Rabies is almost always fatal after symptoms appear, but timely and appropriate post-exposure treatment can prevent the disease.
ERIG vs Anti-Rabies Vaccine: What’s the Difference?
ERIG is frequently called an “ERIG vaccine,” but it is not technically a vaccine. It is an immunoglobulin preparation containing ready-made antibodies.
| Feature | ERIG | Anti-Rabies Vaccine |
|---|---|---|
| Main purpose | Provides immediate antibodies | Stimulates the body to develop antibodies |
| When used | Certain high-risk exposures | Exposures requiring rabies vaccination |
| Administration | Generally once when indicated | Multiple doses according to schedule |
| Quantity | Depends on wounds and weight-based maximum | Depends on vaccination regimen |
| Can replace the other? | No | No, when immunoglobulin is indicated |
ERIG helps provide immediate protection at the exposure site while the vaccine-induced immune response develops. Patients who need both must receive appropriate treatment according to the healthcare professional’s assessment.
For separate vaccine charges, read our Anti-Rabies Vaccine Price in the Philippines guide.
ERIG vs HRIG: Which Is More Expensive?
Rabies immunoglobulin comes in two major forms:
- ERIG: Equine rabies immunoglobulin, produced from purified horse-derived antibodies.
- HRIG: Human rabies immunoglobulin, produced from human plasma.
| Comparison | ERIG | HRIG |
|---|---|---|
| Source | Horse-derived antibodies | Human plasma |
| Maximum dose | 40 IU/kg | 20 IU/kg |
| General cost | Lower | Higher |
| Purpose | Rabies post-exposure treatment | Rabies post-exposure treatment |
| Allergic reactions | Possible | Possible |
HRIG generally costs more than ERIG, but there were insufficient comparable current Philippine listings to establish a dependable HRIG price range. Both products require appropriate clinical administration.
The choice should be based on medical suitability, availability, and professional assessment rather than price alone.
How Much Does Complete Animal Bite Treatment Cost With ERIG?
The ERIG charge is only one part of the possible treatment cost. Depending on the injury and vaccination history, the patient may also need:
| Possible Additional Charge | When It May Apply |
|---|---|
| Anti-rabies vaccine | When post-exposure vaccination is indicated |
| Consultation | If charged separately |
| Wound cleaning and dressing | Depending on the injury |
| Tetanus vaccine or antitoxin | Based on wound and immunization assessment |
| Antibiotics | When medically indicated |
| Additional wound treatment | For injuries requiring further care |
| Follow-up rabies vaccine visits | To complete the prescribed course |
Example: Private Clinic First-Visit Cost
Using Pallad Health’s published individual prices:
| Service | Example Price |
|---|---|
| ERIG starting charge | ₱1,800 |
| Anti-rabies vaccine | ₱650 |
| Consultation | ₱400 |
| Wound care | ₱100 |
| Illustrative subtotal | ₱2,950 |
This is an arithmetic example, not a published package or guaranteed bill. The amount may be higher if more ERIG, tetanus prevention, or additional wound care is required. Some facilities may bundle services rather than charge each item separately.
For related expenses, see our Tetanus Toxoid Vaccine Price in the Philippines guide.
Does PhilHealth Cover ERIG?
Yes. PhilHealth includes rabies immunoglobulin in its Animal Bite Treatment Package. The package benefit is ₱5,850, as stated in PhilHealth’s March 2025 announcement and official benefits information.
The package covers eligible services such as:
- Rabies vaccine
- Rabies immune globulin, including purified ERIG or HRIG
- Local wound care
- Tetanus toxoid and anti-tetanus serum
- Antibiotics
- Medical supplies such as syringes, alcohol, and antiseptics
Treatment must meet the applicable PhilHealth benefit rules and be provided through an accredited Animal Bite Treatment Package provider.
Will PhilHealth Pay the Entire ERIG Bill?
Not necessarily. The ₱5,850 is the package benefit paid under PhilHealth’s rules. It is not the retail price of ERIG, and it is not automatically deducted from every pharmacy purchase or private clinic bill.
Your final charges depend on eligibility, the provider’s accreditation and billing arrangements, and which services are included. Before treatment, ask whether the facility can process the Animal Bite Treatment Package and what, if anything, you must pay.
Does an HMO Cover ERIG?
HMO coverage depends on the patient’s policy and provider. Some plans include emergency treatment or animal-bite services, but ERIG may be subject to separate coverage rules, exclusions, or limits.
Ask your HMO:
- Is Category III animal-bite treatment covered?
- Is ERIG or HRIG included?
- Is the clinic accredited?
- Is an LOA required?
- Are follow-up vaccine doses covered?
- Will there be any co-payment?
Do not delay urgent medical assessment while waiting for routine authorization.
Senior Citizen and PWD Discounts
Eligible senior citizens and persons with disabilities in the Philippines may qualify for a 20% discount and applicable VAT exemption on covered medicines and medical services.
The actual discount depends on the patient’s eligibility, required documents, the type of charge, and applicable billing rules. Bring valid identification and any required prescription documents.
Ask the facility to identify which parts of the bill qualify, particularly if PhilHealth benefits, government subsidies, or promotions also apply.
Who Needs ERIG After an Animal Bite?
ERIG is not required after every dog bite or cat scratch. A healthcare professional determines whether rabies immunoglobulin is indicated based on the exposure category, vaccination history, and other clinical circumstances.
| Exposure Category | Examples | General Recommendation |
|---|---|---|
| Category I | Touching or feeding animals; licks on intact skin | Washing; rabies post-exposure vaccination generally not required |
| Category II | Minor scratches without bleeding; nibbling uncovered skin | Wound washing and rabies vaccination |
| Category III | Bites or scratches penetrating the skin; saliva on broken skin or mucous membranes; direct bat exposure | Wound washing, rabies vaccination, and immunoglobulin when indicated |
A small wound may still represent a serious exposure. Bites involving the face, head, neck, hands, or multiple wounds need prompt assessment.
What If You Were Already Vaccinated Against Rabies?
People who previously completed an appropriate rabies vaccination course generally do not need rabies immunoglobulin after a new exposure. However, booster vaccination may still be required, and certain patients, including those with significant immune impairment, may need special assessment.
Bring previous vaccination records to the Animal Bite Treatment Center.
How Soon Should ERIG Be Given?
When indicated, ERIG should be administered as soon as possible, preferably when rabies vaccination begins. Under standard guidance, rabies immunoglobulin may generally be given within seven days after the first rabies vaccine dose.
It is generally not indicated after that period. If ERIG is unavailable at the first visit, do not delay starting the rabies vaccine. The treating professional can advise how to obtain the appropriate immunoglobulin within the recommended period.
What to Do Immediately After a Dog or Cat Bite
If you have been bitten or scratched by an animal that may transmit rabies:
- Wash the wound thoroughly with soap and running water for at least 15 minutes.
- Seek medical assessment at an Animal Bite Treatment Center or hospital promptly.
- Explain when and how the exposure happened.
- Bring previous rabies vaccination records, if available.
- Complete the recommended treatment schedule.
Do not apply traditional remedies or attempt to administer ERIG yourself. Do not postpone assessment simply because the animal appears healthy or has a reported vaccination history.
Frequently Asked Questions
Magkano ang ERIG vaccine sa Pilipinas?
Selected Philippine pharmacy listings show ERIG at approximately ₱1,800–₱2,160 per vial. Private clinics advertise different starting prices and billing methods, including per-infiltration and per-vial charges. The total depends on the amount required and additional treatment fees.
Libre ba ang ERIG sa public hospital?
Some government Animal Bite Treatment Centers provide ERIG or other rabies immunoglobulin free of charge. Availability depends on the facility, eligibility, and medicine stock. Davao Regional Medical Center is one documented example of a hospital advertising free rabies immunoglobulin services.
How many ERIG vials does a 60 kg adult need?
The calculated maximum dose for a 60 kg adult is 2,400 IU. This is equivalent to 2.4 vials containing 1,000 IU each. However, the clinician may administer less than the maximum based on wound requirements. It does not automatically mean the patient must purchase three complete vials.
Is ERIG the same as an anti-rabies vaccine?
No. ERIG contains ready-made antibodies that provide immediate passive protection. The anti-rabies vaccine stimulates the body to develop its own antibodies. When both are indicated, ERIG does not replace the vaccine series.
Do I always need ERIG after a dog bite?
No. ERIG is primarily used for certain Category III rabies exposures in people who require rabies immunoglobulin. Minor scratches without bleeding may require vaccination without immunoglobulin. A healthcare professional must classify the exposure.
Can children receive ERIG?
Yes. ERIG may be administered to children when clinically indicated. The healthcare professional calculates the appropriate maximum dose using body weight and determines the amount required for wound infiltration.
Is ERIG given only once?
ERIG is generally administered once during a rabies post-exposure treatment course when indicated. The anti-rabies vaccine follows a separate schedule that may require several administrations.
Does ERIG require a skin test?
Philippine treatment protocols may include ERIG skin testing, but WHO guidance does not recommend routine skin testing for modern purified ERIG because it does not reliably predict severe allergic reactions. The treating facility should follow its current clinical protocol and be prepared to manage allergic reactions.
Can I buy ERIG from a pharmacy and bring it to a clinic?
Some pharmacies and medical suppliers list ERIG for sale, but a clinic may not accept patient-supplied immunoglobulin because of storage, cold-chain, and product-verification requirements. Confirm with the treating facility before purchasing. ERIG should not be self-administered.
Does PhilHealth cover ERIG?
Yes. Eligible rabies immunoglobulin treatment is included in PhilHealth’s ₱5,850 Animal Bite Treatment Package at accredited providers, subject to applicable benefit rules. The package also includes qualifying rabies vaccination, wound care, and other related services.
Before You Pay for ERIG
The best facility is not necessarily the one advertising the lowest injection price. The priority is receiving appropriate post-exposure treatment without unnecessary delay.
Before paying, ask:
- Is ERIG available today?
- Does my exposure require ERIG?
- Is the charge per vial, per infiltration, or based on weight?
- Does the price include the full amount required for my wounds?
- Are consultation, rabies vaccine, wound care, and tetanus treatment charged separately?
- Is free or subsidized treatment available?
- Is the clinic accredited for PhilHealth’s Animal Bite Treatment Package?
- What follow-up vaccine visits are required?
Key price takeaway: Selected pharmacy listings place ERIG at approximately ₱1,800–₱2,160 per vial, while private clinic charges use different billing methods. Your actual treatment bill may be higher or lower than a full-vial purchase calculation. Some public facilities provide free treatment, and PhilHealth’s Animal Bite Treatment Package may help eligible patients.
