Why This Information Matters
This Medicare Part D dataset provides transparency into the provider’s prescribing patterns, helping you understand the scope and nature of their pharmaceutical care. Here’s what you can learn:
- Prescribing Trends: See which medications—both generic and brand-name—this provider has most frequently prescribed.
- Specialization Insights: The types of drugs prescribed can give insight into the provider’s areas of focus or specialization, whether it’s managing chronic conditions, addressing acute illnesses, or providing preventive care.
- Cost Awareness: Learn about the total drug costs associated with these prescriptions, which may help you anticipate your own costs and coverage needs.
- Patient-Centered Decision Making: Understanding a provider’s prescribing practices helps you align their expertise with your health goals, ensuring the care you receive is consistent with your expectations.
- Generic Name
- Acyclovir
- Specialty
- Infectious Disease
- Times Prescribed
- 23
- Number of 30-Day Refills Prescribed
- 34
- What is this prescription?
- A GUANOSINE analog that acts as an antimetabolite. Viruses are especially susceptible. Used especially against herpes.
- What is this prescription used for?
- Acyclovir is used to treat infections caused by certain types of viruses. It treats cold sores around the mouth (caused by herpes simplex), shingles (caused by herpes zoster), and chickenpox. This medication is also used to treat outbreaks of genital herpes. In people with frequent outbreaks, acyclovir is used to help reduce the number of future episodes. Acyclovir is an antiviral drug. However, it is not a cure for these infections. The viruses that cause these infections continue to live in the body even between outbreaks. Acyclovir decreases the severity and length of these outbreaks. It helps the sores heal faster, keeps new sores from forming, and decreases pain/itching. This medication may also help reduce how long pain remains after the sores heal. In addition, in people with a weakened immune system, acyclovir can decrease the risk of the virus spreading to other parts of the body and causing serious infections.

- What is this prescription?
- A pyrrole and heptanoic acid derivative, HYDROXYMETHYLGLUTARYL-COA REDUCTASE INHIBITOR (statin), and ANTICHOLESTEREMIC AGENT that is used to reduce serum levels of LDL-CHOLESTEROL; APOLIPOPROTEIN B; and TRIGLYCERIDES. It is used to increase serum levels of HDL-CHOLESTEROL in the treatment of HYPERLIPIDEMIAS, and for the prevention of CARDIOVASCULAR DISEASES in patients with multiple risk factors.
- What is this prescription used for?
- Atorvastatin is used along with a proper diet to help lower bad cholesterol and fats (such as LDL, triglycerides) and raise good cholesterol (HDL) in the blood. It belongs to a group of drugs known as statins. It works by reducing the amount of cholesterol made by the liver. Lowering bad cholesterol and triglycerides and raising good cholesterol decreases the risk of heart disease and helps prevent strokes and heart attacks. In addition to eating a proper diet (such as a low-cholesterol/low-fat diet), other lifestyle changes that may help this medication work better include exercising, losing weight if overweight, and stopping smoking.

- What is this prescription?
- A semisynthetic antibiotic produced from Streptomyces mediterranei. It has a broad antibacterial spectrum, including activity against several forms of Mycobacterium. In susceptible organisms it inhibits DNA-dependent RNA polymerase activity by forming a stable complex with the enzyme. It thus suppresses the initiation of RNA synthesis. Rifampin is bactericidal, and acts on both intracellular and extracellular organisms. (From Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 9th ed, p1160)
- Generic Name
- Testosterone
- Specialty
- Infectious Disease
- Times Prescribed
- 18
- Number of 30-Day Refills Prescribed
- 29
- What is this prescription?
- A potent androgenic steroid and major product secreted by the LEYDIG CELLS of the TESTIS. Its production is stimulated by LUTEINIZING HORMONE from the PITUITARY GLAND. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to DIHYDROTESTOSTERONE or ESTRADIOL.
- What is this prescription used for?
- This medicated patch contains testosterone. It is used for hormone replacement in men who are not able to produce enough testosterone (for example, due to hypogonadism). This medication is absorbed through the skin, enters your bloodstream, and helps your body reach normal testosterone levels. Testosterone helps the body to develop and maintain the male sexual characteristics (masculinity), such as a deep voice and body hair. It also helps to maintain muscle and prevent bone loss, and is necessary for natural sexual ability/desire. This drug should not be used by women.
