When my 12-year-old started taking medication for anxiety and bipolar disorder, I thought the hardest part would be finding the right dose. What I didn’t expect was how careful we would need to be about other doctors adding medications to his regimen, that benefit his health. Even simple things like cold medicine or ibuprofen turned out to matter.

Psychiatric medications, like those prescribed for ADHD, anxiety, or mood issues, can interact with both prescriptions and over-the-counter meds. In children, these interactions can cause anything from stomach upset and drowsiness to mood swings or, in rare cases, dangerous side effects.

Common Interactions to Watch For

• Cold medicine + ADHD meds (like Adderall): can cause a racing heart, jitteriness, or heightened anxiety.
• Ibuprofen + antidepressants (like Prozac or Zoloft): may increase the risk of stomach bleeding, especially if taken frequently.
• Cough medicine with dextromethorphan (DXM) + SSRIs: can trigger serotonin syndrome, a serious condition marked by confusion, shivering, restlessness, and sometimes agitation.
• Antibiotics + psychiatric meds: certain antibiotics can change how psych meds are absorbed, making them either too strong or not effective enough.

When a new medication was added to my son’s regimen, his whole attitude changed almost overnight. He became irritable, got in trouble at school, and seemed angry all the time. After some digging, we realized the new drug was interacting with his Lithium. We removed it immediately, but the medication takes up to a month to fully leave the body. That meant weeks of riding out the storm while supporting him the best we could.

This was a wake-up call. It wasn’t just about monitoring his prescribed medications, but also about paying attention to everyday over-the-counter options and even “routine” prescriptions from other doctors.

If your child is on psychiatric medication, always double-check before adding anything new, even if it seems minor. This doesn’t mean living in fear, it means being aware and proactive. Ask your child’s psychiatrist or pharmacist before starting new medications, supplements, or even common cold remedies.

At the end of the day, you are your child’s strongest advocate. By asking questions and paying attention, you can help keep their treatment safe and effective.
