# These 10 Medications May Raise Your Risk of Heat-Related Illness
Ten common medications increase your child's vulnerability to heat illness during summer months and hot weather, according to health research. Parents giving their kids these drugs should take extra precautions when temperatures rise.
Antihistamines like diphenhydramine (Benadryl) and cetirizine (Zyrtec) reduce the body's ability to sweat, making heat dissipation harder. Stimulant medications used for ADHD, including methylphenidate (Ritalin) and amphetamine-based drugs (Adderall), raise heart rate and metabolism in ways that generate excess body heat. Decongestants like pseudoephedrine narrow blood vessels, restricting blood flow to the skin where cooling happens.
Other high-risk medications include certain antidepressants, some blood pressure medications, anticholinergic drugs, diuretics, and topiramate (a medication for seizures and migraines). These drugs affect sweating, blood vessel function, or fluid balance in ways that compromise heat regulation.
Heat-related illness ranges from heat exhaustion to heat stroke. Symptoms include excessive thirst, weakness, dizziness, nausea, rapid heartbeat, and confusion. Heat stroke requires emergency care.
Parents whose children take these medications should increase hydration during hot weather, limit outdoor activity during peak heat hours (10 a.m. to 4 p.m.), dress kids in loose, light clothing, and watch closely for warning signs. Never stop medication without talking to your child's doctor first. Instead, discuss summer safety strategies at your next appointment.
Talk with your pediatrician or pharmacist about your child's specific medications and their heat-related risks. They can offer personalized guidance for your family's situation. For children
