Yes, this is a well-established area of VA disability law. Under 38 CFR 3.310, a secondary condition is one that is caused or aggravated by an already service-connected disability or its treatment. If you are being treated for a service-connected mental health condition (such as depression or PTSD) and the prescribed medication causes a new medical problem, such as tardive dyskinesia from certain antidepressants or antipsychotics, that new condition can potentially be service-connected on a secondary basis.
To win a secondary service connection claim, you generally need three things: (1) a current diagnosis of the secondary condition, (2) proof of an existing service-connected primary condition, and (3) a medical nexus opinion linking the two, specifically stating that the secondary condition was caused or aggravated by the medication used to treat the primary condition. This nexus evidence is the most critical piece. Many veterans in this situation ask their treating psychiatrist or a private physician to write a nexus letter explicitly tying the new diagnosis to the medication regimen prescribed for the service-connected disability, citing specific drug names and dates.

Analyze my claim free →To file, you would submit VA Form 21-526EZ for a new secondary condition, or VA Form 20-0995 (Supplemental Claim) if you already have a prior decision on the primary condition and are adding new evidence of this complication. The claim should clearly state the condition is secondary to the specific service-connected disability and list the medication as the causal mechanism. A fully developed claim with supporting medical records, pharmacy records showing the medication timeline, and a nexus statement tends to move through the system more smoothly than one lacking medical evidence.
It is also worth noting that aggravation claims are valid even if the medication only worsened a preexisting condition rather than caused it outright, per 38 CFR 3.310(b). Outcomes vary significantly based on the strength of the medical nexus opinion and the specific diagnostic criteria for the secondary condition, so there is no guaranteed approval path, but the legal framework for this type of claim is firmly established.
The concrete next step is to request copies of your pharmacy and treatment records documenting the medication history, then ask your prescribing physician for a written nexus opinion connecting the new diagnosis to the medication prescribed for your service-connected condition before filing a secondary claim.
