From the Guidelines
Several medications in this list can potentially cause heat intolerance as a side effect, including metformin ER, Mounjaro, fluoxetine, buspirone, and gabapentin, which can affect the body's thermoregulation by influencing blood vessel dilation, sweat gland function, or central temperature regulation mechanisms 1.
Medications Causing Heat Intolerance
- Metformin ER (500mg twice daily) may cause increased sweating in some patients, as it is a common side effect of this medication 1.
- Mounjaro (tirzepatide 5mg weekly injection) can affect temperature regulation, although the exact mechanism is not well understood 1.
- Fluoxetine (20mg daily) and buspirone (10mg twice daily) are both known to occasionally cause increased sweating or heat sensitivity, which can be a concern for patients taking these medications 1.
- Gabapentin (300mg three times daily) may also contribute to heat intolerance in some individuals, as it can affect the body's thermoregulation mechanisms 1.
Recommendations
- If experiencing significant heat intolerance, it's essential not to discontinue any medications without consulting your healthcare provider 1.
- Stay well-hydrated, avoid prolonged sun exposure, and use cooling measures during hot weather to minimize the risk of heat-related illnesses 1.
- Your doctor may consider adjusting medication timing or dosages if heat intolerance is severely affecting your quality of life, as the benefits of these medications may outweigh the risks in some cases 1.
From the Research
Medications and Heat-Related Illness
- The medications listed, including metformin, rosuvastatin, and others, may have various side effects, but their relationship to heat-related illness is not directly established in the provided studies.
- However, a study published in the Journal of Clinical Pharmacy and Therapeutics 2 suggests that certain medications, such as diuretics, anticholinergics, and psychotropics, may increase the risk of dehydration and heat-related illness, especially in elderly people taking multiple medications.
Specific Medications
- Metformin, a medication for type 2 diabetes, has been studied extensively, but its relationship to heat-related illness is not mentioned in the provided studies 3, 4.
- Rosuvastatin, a statin used to lower cholesterol, has been shown to be effective in reducing LDL cholesterol in diabetic patients, but its relationship to heat-related illness is not established in the provided studies 5.
- Mounjaro (tirzepatide), a medication for type 2 diabetes, has been studied in a clinical trial, but its relationship to heat-related illness is not mentioned in the provided study 6.
- Eliquis, a blood thinner, and other medications listed, such as buspirone and fluoxetine, do not have established relationships to heat-related illness in the provided studies.
Heat-Related Illness Prevention
- The study published in the Journal of Clinical Pharmacy and Therapeutics 2 emphasizes the importance of preventive measures, such as reviewing medications and identifying thermoregulatory issues, to reduce the risk of heat-related illness, especially in elderly people taking multiple medications.
