Human immunodeficiency virus (HIV) and Hepatitis C virus (HCV) infections can cause significant morbidity and mortality if left untreated. The Centers for Disease Control and Prevention (CDC) estimates that 1.2 million adults and adolescents are living with HIV infection1 and 2.4 million individuals are living with chronic HCV infection.2 A significant portion of the individuals infected do not know that they are infected. Fortunately, there are available antiviral treatments that are effective at suppressing HIV replication and eradicating HCV.3,4 These treatments not only decrease the chances of disease progression but also decrease the risk of transmitting the diseases to other individuals.3,4 Therefore, it is vital that appropriate patient groups are screened for these viral infections and then linked to care with appropriate healthcare providers.

All adults ages 18 and over should be screened one time for HCV. All pregnant persons should be screened during each pregnancy. Individuals who are at increased risk of transmission should have periodic repeat screening tests completed.4 HCV is most efficiently transmitted by infected blood-to-blood contact. Therefore, those individuals who should be screened due to risk include those who could have come into contact with HCV-infected blood, such as injection drug users, patients on long-term hemodialysis, healthcare workers after a needle stick injury, children born to HCV-infected mothers, and patients receiving blood before 1992.4 Additionally, individuals who were ever incarcerated, have HIV infection, have unexplained liver disease, and solid organ donors should be screened for HCV.4

All individuals at least 13 years of age should be tested for HIV at least once as a part of routine healthcare.5 For those patients who may come into contact with HIV-infected bodily fluids (e.g., blood, semen, vaginal fluids, rectal fluids, breastmilk), at least yearly screening is recommended.5

Patients diagnosed with HIV and/or HCV should undergo further testing, evaluation, and counseling. The counseling for both infections includes ways to reduce the risk of transmission to others and encouragement to have sexual partners tested.3,4 Additionally, counseling should focus on reducing disease progression, both through antiviral treatment and non-pharmacologic methods. For example, alcohol consumption should be avoided in patients with HCV because both can hasten liver function decline.4 Patients diagnosed with HIV should be counseled about the risk of and signs and symptoms of opportunistic infections.3

In addition to direct clinical care, pharmacists are involved in the public health aspect of HIV and HCV care by participating in the screening and detection process for both viruses.6,7 Pharmacists assist in identifying patients and patient groups who should be screened for HIV and/or HCV, conducting the screening test when applicable, counseling patients on the results of the screening test, assisting other health care providers with interpretation of screening results, and linking patients to further care if the screening test returns positive.



You are a pharmacist practicing in a busy clinic setting. One of your primary roles is to counsel patients who are newly diagnosed with infectious diseases, including HIV and HCV. Your counseling points during these encounters generally include an overview of the viral infections, prevention of transmission, and general points of treatment.

CC: “My new fiancée wanted me to get ‘checked up’ by the doctor before we got married.”

Patient: RC is a 55-year-old male (70 in, 200 lb) who works as a car mechanic in Georgia. At his fiancée’s request, he saw his usual PCP who ordered a number of lab tests. He has now received new diagnoses of HIV and HCV infection from his physician and is presenting to the clinic pharmacist.

HPI: Presented to clinic one month ago. No significant complaints at that time or at this visit. Patient denies any history of rash, fever/chills, night sweats, and jaundice.

PMH: Hypertension (x 5 years); HIV (diagnosed at this visit); Hepatitis C (diagnosed at this visit)

Sexual History:

  • Identifies as heterosexual and has been sexually active since 18 years old
  • Monogamous during prior 15 year marriage to a woman
  • For the last five years, has had vaginal, anal, and oral sex with multiple female sexual partners until meeting current fiancée six months ago
  • Has not participated in oral, anal, or vaginal sex in current relationship with fiancée, but has been monogamous

SDH: RC is English-speaking with a high-school diploma (with a few trade school courses). His annual income (with fiancée) is approximately $75,000. He lives in a single family home with his fiancée.


  • Hydrochlorothiazide 25 mg daily
  • Ibuprofen 200 mg every 6 hours as needed for “aches and pains”

Allergies: NKDA


  • BP (seated) 128/76 mm Hg
  • Other vital signs WNL


  • HIV screen: positive
  • HIV viral load: 56,783 copies/mL
  • CD4 count: 562 cells/mm3
  • HIV genotype: wild type virus
  • HCV screen: positive
  • HCV viral load: 125,000 IU/mL
  • Hepatitis A antibody: Nonreactive
  • Hepatitis B surface antigen: Nonreactive
  • Hepatitis B surface antibody: Nonreactive
  • Hepatitis B core antibody: Nonreactive
  • Other labs: WNL
  • Other health screenings: negative

Case Questions

1. The patient understands how he potentially contracted HIV due to his sexual activity in the last year, but he wants to know if that’s how he got Hepatitis C as well. How do you counsel him about the similarities and differences in the transmission risks of the two viruses?

2. Now that the patient knows how HIV and Hepatitis C are transmitted, he desperately wants to know how to prevent transmitting it to his fiancée. What options are there for both him and his fiancée to lessen transmission risks?

3. RC is unsure that he is ready to start treatment for either disease yet. Besides further discussing treatment details with him, what non-pharmacological recommendations can you give him to help lessen his risk of disease progression?

4. How would you counsel the patient about the possibility of being a blood and/or organ donor?

5. Because a diagnosis of HIV and HCV can be devastating and carries negative stigma, what steps can you take to help the patient cope with the new diagnosis?

Author Commentary

HIV and HCV are two common viral illnesses that create significant morbidity and mortality. Pharmacists play several important roles in the care of these patients. As modeled in the above case, pharmacists are commonly involved with an interdisciplinary healthcare team and will counsel patients shortly after a diagnosis is made. While the bulk of this conversation usually centers on antiviral medications the patient will receive for treatment, there are other important counseling points that pharmacists should make regarding transmission risks and other management considerations besides antiviral treatment, including but not limited to determining need for vaccinations, particularly Hepatitis A and B, and maintaining a healthy lifestyle.

Patient Approaches and Opportunities

Receiving a diagnosis of HIV and/or Hepatitis C can be a devastating situation for a patient. There is still stigma surrounding diagnoses of these diseases even though they are treatable. Therefore, it is important to assess how the patient is coping mentally and emotionally during this counseling session. It might be prudent to offer a follow-up clinic visit or phone call to discuss some of the necessary counseling points if the patient seems overwhelmed. Additionally, keep in mind possible cultural concerns that might cause patients to feel uncomfortable talking with the pharmacist about these particular diagnoses. Asking the patient what you can do to make them more comfortable for this discussion is prudent. One important counseling point at this time of diagnosis is discussion about risks of transmission with sexual partners. The patient’s sexual partner(s) should be screened for all sexually transmitted infections, including HIV and HCV. This is also an ideal time to counsel a patient on safer sexual practices, such as barrier methods, as well as the possible use of pre-exposure prophylaxis if the sexual partner is not infected with HIV.
