Is Viagra a Loaded Gun?

The following risk management alert was written by the APA-sponsored Professional Liability Insurance Program's risk management department.

In March 1998 the Food and Drug Administration approved the drug Viagra (sildenafil citrate) for use in the treatment of erectile dysfunction. Since then, consumer response has exceeded even the most ambitious forecasts. As responsible physicians, psychiatrists need to consider how the frenzy surrounding Viagra may increase health risks for their patients and liability risks for themselves.

The tools for minimizing liability risks associated with Viagra are the same as those used to minimize the risks associated with any newly approved drug. Patient referrals, education, and documentation are the keys.

Risk 1

You may be viewed by friends, family, and patients as a source of information, samples, and prescriptions for Viagra. However, prescribing or dispensing medications and/or professional advice may inadvertently create a physician-patient relationship, complete with attendant liabilities.

Tip: Refer family members and friends to another qualified health care provider.

Risk 2

A newly approved drug may carry a greater risk for the patient and greater exposure for you, because postapproval information on the drug does not yet exist. For example, there have been no controlled studies about potential interactions between Viagra and the protease inhibitors used to treat HIV infection.

Tip: Educate yourself about this new drug. Become more knowledgeable about its indications, contraindications, and complications. In addition to the FDA's and manu-facturer's information, consult with other resources, such as other scientific literature and medical specialists, such as urologists. (See end of article for Viagra information on the Internet.)

Risk 3

Realize that off-label use of a newly approved drug increases risks even more, because relevant information is scarce or nonexistent. Prescribing a drug for any use other than that specifically approved by the FDA is an off-label use. Therefore, prescribing Viagra for any condition other than erectile dysfunction constitutes an off-label use (for example, prescribing for decreased libido, prescribing to women).

Tip: Again, educate yourself and stay informed as new information becomes available. Maintain a file (separate from your patient files) containing any scientific literature and professional information that you rely on to support the use of newly approved medications and off-label use of medications.

Risk 4

Always remain aware of the high probability for misuse and/or abuse of drugs. This is especially true of Viagra. For example, there have been reports of individuals withholding pertinent information from their physicians to obtain a prescription and of individuals wanting a prescription so they can slip it into their partner's drink.

Tip: Consider including questions about whether a patient has access to and is using Viagra as part of your standard assessment and evaluation. Advise patients that for you to evaluate and treat them appropriately (including the selection of prescription medication), they must inform you of all other medications and treatments they are using, whether prescription or nonprescription.

Risk 5

Medical conditions and risks can be overlooked in the frenzy to prescribe and take "miracle drugs" like Viagra.

Tip: Assess whether the patient who is asking about Viagra, or is already on Viagra, has had the recommended workup, including a thorough medical history and physical exam. This will assist you in determining with whom you should be coordinating treatment and what exams, lab work, referrals, or consultations you should be ordering. Be realistic about your own professional limitations. Consider a professional consultation or a referral to another physician with appropriate training and expertise, when appropriate.

Risk 6

"Stacking" treatments, or prescribing several medications at a time, may increase the risk of adverse interactions. Nevertheless, you may consider prescribing in this manner due to decreased libido and sexual dysfunction caused by psychoactive medications.

Tip: Follow all the preceding risk management tips when considering stacking treatments. One consumer group, Public Citizen's Health Research Group, has already petitioned the FDA to strengthen Viagra's safety warnings, because men may be taking Viagra to treat erectile dysfunction caused by taking other prescription drugs.

Risk 7

Malpractice allegations related to prescribing medications would most likely include a claim of lack of, or insufficient, informed consent, as well as claims of a deviation from the standard of care.

Tip: As always, obtain the patient's informed consent, and document the consent. Your documentation should reflect that the patient was informed about the nature of the treatment; the risks, benefits, and potential side effects of the treatment; any alternatives to the treatment; the risks and benefits of any alternatives; the risks and benefits of doing nothing; and what to do if problems or questions arise. In addition, clarify to the patient whether the proposed treatment is an approved or an off-label use.

Keep copies in the patient's medical record of all written instructions or informational materials provided to the patient.

Remember that informed consent is a continuous process. Record the discussions between yourself and the patient about the medication, the response to the drug, any subsequent actions taken by you, and the basis for your clinical decision-making process.

Additional Tip

Including the patient's partner in the treatment program can be especially important when dealing with sexual dysfunction. If you do so, establish a separate file for the partner and for each person attending a patient's session. Not only will this help ensure confidentiality, but also it will facilitate the ability to process any requests for patient information in a timely manner.

In conclusion, if your actions regarding Viagra, or any other medication, meet acceptable medical standards, and your records adequately document the medical treatment given, then you should be able to minimize your professional liability exposure.
