Medications to Manage Injection-Site Pain on Testosterone Cypionate: First-Line and Beyond

What the label says about injection-site pain

The Depo-Testosterone label lists "inflammation and pain at the site of intramuscular injection" in its adverse reactions section with no rate, no expected duration and no suggested treatment [1]. The same label states the drug is for intramuscular use only, should not be given intravenously, and should be injected deep in the gluteal muscle, and that the 100 mg/mL and 200 mg/mL solutions contain cottonseed oil, benzyl benzoate and benzyl alcohol [1].

Hypersensitivity reactions the label lists

Depo-Testosterone lists hypersensitivity, including skin manifestations, as well as anaphylactoid reactions, and known hypersensitivity to the drug is a contraindication [1]. Spreading redness and warmth can also be signs of cellulitis [5].

Over-the-counter pain relievers and their label limits

Ibuprofen. MedlinePlus's ibuprofen entry carries the NSAID class warning: a higher risk of heart attack or stroke, events that can happen without warning, with risk possibly higher for people who take NSAIDs for a long time or at higher doses. It also warns of ulcers, bleeding or holes in the esophagus, stomach or intestine, which can happen without warning symptoms, with risk possibly higher in people who take NSAIDs for a long time, are older, have poor health, smoke or drink large amounts of alcohol [2]. None of that is specific to testosterone cypionate.

Acetaminophen. MedlinePlus classifies acetaminophen as an analgesic and antipyretic that works by changing how the body senses pain [3]. Its warning is hepatic: too much can cause liver damage serious enough to require transplantation or cause death, which can happen by taking more than one acetaminophen-containing product or by not following the label. The entry sets a limit of no more than 4,000 mg a day from all sources [3]. Acetaminophen also comes in combination cough and cold products [3].

Lidocaine patches. MedlinePlus says nonprescription lidocaine is available to relieve minor pain in the shoulders, arms, back, neck and legs in adults and children 12 and older. The 4% patch is applied 3 to 4 times daily for no more than 8 hours per application, to clean, dry, intact skin, and not to an open wound, skin that is irritated or red, or skin affected by a rash, burn or other skin problem [4]. That entry covers patches, not creams or gels.

What about prescription drugs and antibiotics?

The Depo-Testosterone label does not recommend a prescription NSAID, an oral corticosteroid or an antihistamine for injection-site soreness [1]. MedlinePlus describes cellulitis as a common skin infection caused by bacteria, usually treated with antibiotics taken by mouth, and says it usually goes away after 7 to 10 days of antibiotics, though more severe cases may take longer [5]. It is diagnosed on a physical exam, at which the provider may mark the edge of the redness with a pen to see whether it spreads. The entry lists redness or inflammation that grows as the infection spreads, tight glossy skin, warmth, tenderness, fever with chills and sweating, and fatigue among the signs [5].

Would a different route or technique change the pain?

Depo-Testosterone is labeled for deep gluteal intramuscular injection at 50 to 400 mg every two to four weeks, in 100 mg/mL and 200 mg/mL strengths, and not for intravenous use [1]. The label does not describe a subcutaneous cypionate dose or compare injection routes for site pain [1].
