Precautions and Warnings With Chlorpheniramine
Warnings and precautions to be aware of prior to taking chlorpheniramine include the following:
- This medication can cause blurred vision, dizziness, and drowsiness. Be sure to see how chlorpheniramine affects you before driving or operating heavy machinery.
- Elderly individuals may be more susceptible to chlorpheniramine side effects and may be more likely to be taking medications that interact with this drug. If you are over the age of 60, it is best to check with your healthcare provider before taking chlorpheniramine. It can worsen many conditions common in the elderly, such as an enlarged prostate or Alzheimer's disease.
- Chlorpheniramine can worsen stomach ulcers, GERD, glaucoma, or an enlarged prostate. If you have one of these conditions, do not take this medication without checking with your healthcare provider first.
- This drug can cause breathing problems in people with asthma or COPD, including chronic bronchitis and emphysema. If you have either of these conditions, check with your healthcare provider before taking chlorpheniramine.
- Make sure to check with your healthcare provider before taking chlorpheniramine if you have hyperthyroidism, any heart problems (including heart disease) or high blood pressure, as it is possible that this medication could worsen these conditions.
- Never combine oral chlorpheniramine products with chlorpheniramine skin products. Also, do not use chlorpheniramine skin products over a large area of the body. Either of these situations could lead to an overdose.
- Chlorpheniramine is considered a pregnancy Category B medication. This means that it probably will not cause problems if used during pregnancy, although the full risks are not currently known (see Chlorpheniramine and Pregnancy).
- It is unknown if chlorpheniramine passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking the drug (see Chlorpheniramine and Breastfeeding).
