Pentacel (tetanus toxoid conjugate) Diphtheria, Haemophilus Influenzae, Pertussis, Tetanus, and Polio Vaccine is used to prevent these diseases in children ages 6 weeks to 4 years. Common side effects of Pentacel include redness, pain, tenderness, or swelling where the shot was given, fever, fussiness or crying, headache, tiredness, joint pain, body aches, loss of appetite, nausea, diarrhea, or vomiting.

Pentacel is given in a series of 4 doses at ages 15 to 18 months, 2, 4, and 6. The first dose can be given to a child as young as 6 weeks old. Pentacel may interact with other drugs. Before your child receives this vaccine tell your doctor if they have received any other vaccines, or if in the past 2 weeks have taken drugs that can weaken their immune system such as steroids, medications to treat autoimmune disorders like psoriasis, or medications used to treat organ transplant rejection. Make sure your child receives all 4 doses of Pentacel. This medication is not indicated for women of child bearing age so should not be taken if you are pregnant or breastfeeding.

Our Pentacel (tetanus toxoid conjugate) Diphtheria, Haemophilus Influenzae, Pertussis, Tetanus, and Polio Vaccine Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Pentacel in Detail - Patient Information: Side Effects

Your child should not receive a booster vaccine if he or she had a life-threatening allergic reaction after the first shot.

Keep track of any and all side effects your child has after receiving this vaccine. When the child receives a booster dose, you will need to tell the doctor if the previous shots caused any side effects.

Becoming infected with diphtheria, haemophilus influenzae, pertussis, tetanus, or polio is much more dangerous to your child's health than receiving the vaccine to protect against these diseases. Like any medicine, this vaccine can cause side effects, but the risk of serious side effects is extremely low.

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if the child has any of these serious side effects:

  • extreme drowsiness, fainting;
  • fussiness, irritability, crying for an hour or longer;
  • seizure (black-out or convulsions); or
  • high fever.

Less serious side effects may include:

  • redness, pain, tenderness, or swelling where the shot was given;
  • low fever;
  • mild fussiness or crying;
  • headache or tiredness;
  • joint pain, body aches;
  • loss of appetite; or
  • mild nausea, diarrhea, or vomiting.

This is not a complete list of side effects and others may occur. Tell your doctor about any unusual or bothersome side effect. You may report side effects to FDA at 1-800-FDA-1088.

What is Patient Information Overview?

A concise overview of the drug for the patient or caregiver from First DataBank.

Pentacel Overview - Patient Information: Side Effects

SIDE EFFECTS: Pain/swelling/redness at the injection site may occur. Mild fever, irritability/crying, sleepiness, vomiting, loss of appetite, and diarrhea may also occur. If any of these effects persist or worsen, tell the doctor or pharmacist promptly. Consult the doctor or pharmacist about the temporary use of acetaminophen to treat pain and fever due to this vaccine.

Infrequently, temporary symptoms such as fainting/dizziness/lightheadedness, vision changes, numbness/tingling, or seizure-like movements have happened after vaccine injections. Tell your health care provider right away if you have any of these symptoms soon after receiving an injection. Sitting or lying down may relieve symptoms.

Remember that the doctor has prescribed this medication because he or she has judged that the benefit to your child is greater than the risk of side effects. Many children using this medication do not have serious side effects.

Seek immediate medical attention if any of these rare but serious side effects occur: persistent crying (beginning within 48 hours of the injection and lasting longer than 3 hours), high fever (105 degrees F/40 degrees C or higher), little or no response to sound/touch, weak/floppy muscles, seizures.

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact the doctor or pharmacist.

Contact your doctor for medical advice about side effects. The following numbers do not provide medical advice, but in the US, you may report side effects to the Vaccine Adverse Event Reporting System (VAERS) at 1-800-822-7967. In Canada, you may report side effects to Health Canada at 1-866-234-2345.

Pentacel FDA Prescribing Information: Side Effects
(Adverse Reactions)

SIDE EFFECTS

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a vaccine cannot be directly compared to rates in the clinical trials of another vaccine. The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse events that appear to be related to vaccine use and for approximating rates of those events.

In Studies 494-01, 494-03, 5A9908, and P3T06 (Table 1), a total of 5,980 participants received at least one dose of Pentacel (tetanus toxoid conjugate) vaccine, including 4,198 participants who were enrolled in one of three US studies that evaluated the safety of four consecutive doses of Pentacel (tetanus toxoid conjugate) vaccine administered at 2, 4, 6, and 15-16 months of age. In calculating event rates across doses and studies, one subject who received one dose of Pentacel (tetanus toxoid conjugate) vaccine followed by three doses of Control vaccines was included in the control group. Two of the US studies, Study 494-01 and Study P3T06, included a control group that received separately administered vaccines. In Study 5A9908 conducted in Canada, 1,782 participants previously vaccinated with three doses of Pentacel (tetanus toxoid conjugate) vaccine received a fourth dose at 15-18 months of age. Across the four studies, 50.8% of participants were female. Among participants in the three US studies, 64.5% were Caucasian, 9.2% were Black, 12.9% were Hispanic, 3.9% were Asian, and 9.5% were of other racial/ethnic groups. In the two controlled studies, the racial/ethnic distribution of participants who received Pentacel (tetanus toxoid conjugate) and Control vaccines was similar. In the Canadian fourth dose study, 86.0% of participants were Caucasian, 1.9% were Black, 0.8% were Hispanic, 4.3% were Asian, 2.0% were East Indian, 0.5% were Native Indian, and 4.5% were of other racial/ethnic groups.

Solicited Adverse Reactions

The incidence and severity of selected solicited injection site and systemic adverse reactions that occurred within 3 days following each dose of Pentacel (tetanus toxoid conjugate) or Control vaccines in Study P3T06 is shown in Table 6. Information on these reactions was recorded daily by parents or guardians on diary cards. In Table 6, injection site reactions are reported for the Pentacel (tetanus toxoid conjugate) vaccine and DAPTACEL vaccine injection sites.

Following Dose 4, the proportion of temperature measurements that were taken by axillary, rectal or other routes, or not recorded were 62.7%, 34.4%, 2.4% and 0.5%, respectively, for Pentacel (tetanus toxoid conjugate) vaccine, and 61.1%, 36.6%, 1.7% and 0.5%, respectively, for DAPTACEL + ActHIB vaccines.
§ Moderate: interferes with or limits usual daily activity; Severe: disabling, not interested in usual daily activity.

Hypotonic Hyporesponsive Episodes

In Study P3T06, the diary cards included questions pertaining to HHEs. In Studies 494-01, 494-03, and 5A9908, a question about the occurrence of fainting or change in mental status was asked during post-vaccination phone calls. Across these 4 studies, no HHEs, as defined in a report of a US Public Health Service workshop (22) were reported among participants who received Pentacel (tetanus toxoid conjugate) vaccine (N = 5,979), separately administered HCPDT + POLIOVAX + ActHIB vaccines (N = 1,032) or separately administered DAPTACEL + IPOL + ActHIB vaccines (N = 1,455). Hypotonia not fulfilling HHE criteria within 7 days following vaccination was reported in 4 participants after the administration of Pentacel (tetanus toxoid conjugate) vaccine (1 on the same day as the 1st dose; 3 on the same day as the 3rd dose) and in 1 participant after the administration of DAPTACEL + IPOL + ActHIB vaccines (4 days following the 1st dose).

Seizures

Across Studies 494-01, 494-03, 5A9908 and P3T06, a total of 8 participants experienced a seizure within 7 days following either Pentacel (tetanus toxoid conjugate) vaccine (4 participants; N = 4,197 for at least one of Doses 1-3; N = 5,033 for Dose 4), separately administered HCPDT + POLIOVAX + ActHIB vaccines (3 participants; N = 1,032 for at least one of Doses 1-3, N = 739 for Dose 4), separately administered DAPTACEL + IPOL + ActHIB vaccines (1 participant; N = 1,455 for at least one of Doses 1-3), or separately administered DAPTACEL + ActHIB vaccines (0 participants; N = 418 for Dose 4). Among the four participants who experienced a seizure within 7 days following Pentacel (tetanus toxoid conjugate) vaccine, one participant in Study 494-01 had an afebrile seizure 6 days after the first dose, one participant in Study 494-01 had a possible seizure the same day as the third dose, and two participants in Study 5A9908 had a febrile seizure 2 and 4 days, respectively, after the fourth dose. Among the four participants who experienced a seizure within 7 days following Control vaccines, one participant had an afebrile seizure the same day as the first dose of DAPTACEL + IPOL + ActHIBvaccines, one participant ha d an afebrile seizure the same day as the second dose of HCPDT + POLIOVAX + ActHIBvaccines, and two participants had a febrile seizure 6 and 7 days, respectively, after the fourth dose of HCPDT + POLIOVAX + ActHIBvaccines.

Serious Adverse Events

In Study P3T06, within 30 days following any of Doses 1-3 of Pentacel (tetanus toxoid conjugate) or Control vaccines, 19 of 484 (3.9%) participants who received Pentacel (tetanus toxoid conjugate) vaccine and 50 of 1,455 (3.4%) participants who received DAPTACEL + IPOL + ActHIB vaccines experienced a serious adverse event. Within 30 days following Dose 4 of Pentacel (tetanus toxoid conjugate) or Control vaccines, 5 of 431 (1.2%) participants who received Pentacel (tetanus toxoid conjugate) vaccine and 4 of 418 (1.0%) participants who received DAPTACEL + ActHIB vaccines experienced a serious adverse event. In Study 494-01, within 30 days following any of Doses 1-3 of Pentacel (tetanus toxoid conjugate) or Control vaccines, 23 of 2,506 (0.9%) participants who received Pentacel (tetanus toxoid conjugate) vaccine and 11 of 1,032 (1.1%) participants who received HCPDT + POLIOVAX + ActHIB vaccines experienced a serious adverse event. Within 30 days following Dose 4 of Pentacel (tetanus toxoid conjugate) or Control vaccines, 6 of 1,862 (0.3%) participants who received Pentacel (tetanus toxoid conjugate) vaccine and 2 of 739 (0.3%) participants who received HCPDT + POLIOVAX + ActHIB vaccines experienced a serious adverse event.

Across Studies 494-01, 494-03 and P3T06, within 30 days following any of Doses 1-3 of Pentacel (tetanus toxoid conjugate) or Control vaccines, overall, the most frequently reported serious adverse events were bronchiolitis, dehydration, pneumonia and gastroenteritis. Across Studies 494-01, 494-03, 5A9908 and P3T06, within 30 days following Dose 4 of Pentacel (tetanus toxoid conjugate) or Control vaccines, overall, the most frequently reported serious adverse events were dehydration, gastroenteritis, asthma, and pneumonia.

Across Studies 494-01, 494-03, 5A9908 and P3T06, two cases of encephalopathy were reported, both in participants who had received Pentacel (tetanus toxoid conjugate) vaccine (N = 5,979). One case occurred 30 days post-vaccination and was secondary to cardiac arrest following cardiac surgery. One infant who had onset of neurologic symptoms 8 days post-vaccination was subsequently found to have structural cerebral abnormalities and was diagnosed with congenital encephalopathy.

A total of 5 deathsoccurred during Studies 494-01, 494- 03, 5A9908 and P3T06: 4 in children who had received Pentacel (tetanus toxoid conjugate) vaccine (N = 5,979) and one in a participant who had received DAPTACEL + IPOL + ActHIB vaccines (N = 1,455). There were no deaths reported in children who received HCPDT + POLIOVAX + ActHIB vaccines (N = 1,032). Causes of death among children who received Pentacel (tetanus toxoid conjugate) vaccine were asphyxia due to suffocation, head trauma, Sudden Infant Death syndrome, and neuroblastoma (8, 23, 52 and 256 days post-vaccination, respectively). One participant with ependymoma died secondary to aspiration 222 days following DAPTACEL + IPOL + ActHIB vaccines.

Data From Post-Marketing Experience

The following additional adverse events have been spontaneously reported between 1997 and 2007 during the post-marketing use of Pentacel (tetanus toxoid conjugate) vaccine outside of the US, primarily in Canada. Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to vaccine exposure. The following adverse events were included based on severity, frequency of reporting, or the strength of causal association to Pentacel (tetanus toxoid conjugate) vaccine.

  • Gastrointestinal disorders
    Vomiting, diarrhea
  • General disorders and administration site conditions
    Injection site reactions (including inflammation, mass, abscess and sterile abscess), extensive swelling of the injected limb (including swelling that involved adjacent joints),vaccination failure/therapeutic response decreased (invasive H influenzae type b disease)
  • Immune system disorders
    Hypersensitivity (such as rash and urticaria)
  • Metabolism and nutrition disorders
    Decreased appetite
  • Nervous system disorders
    Somnolence, HHE, depressed level of consciousness
  • Psychiatric disorders
    Screaming
  • Apnea, cough
  • Skin and subcutaneous tissue disorders
    Erythema, skin discoloration
  • Vascular disorders
    Pallor

Reporting of Adverse Events

The National Childhood Vaccine Injury Act of 1986 requires physicians and other health-care providers who administer vaccines to maintain in the recipient's permanent medical record the manufacturer, lot number, date of administration, and the name, address and title of the person administering the vaccine. The Act further requires the health-care provider to report to the US Department of Health and Human Services the occurrence of certain adverse events following immunization. For Pentacel (tetanus toxoid conjugate) vaccine, events required to be reported are anaphylaxis or anaphylactic shock within 7 days, brachial neuritis within 2-28 days, encephalopathy or encephalitis within 7 days following vaccination, or any acute complication or sequela (including death) of these events, or any contraindicating event listed in this Pentacel (tetanus toxoid conjugate) vaccine package insert. (23) (24) These events and other suspected adverse reactions should be reported to VAERS at 1-800-822-7967 or http://www.vaers.hhs.gov and to Sanofi Pasteur Inc. at 1-800-822-2463.
