Avoid becoming overheated in hot weather. Chlorpheniramine and methscopolamine increases the risk of heat stroke because it causes decreased sweating and can make you more sensitive to sunlight.
Avoid drinking alcohol. It can increase some of the side effects of chlorpheniramine and methscopolamine.
Avoid using other medicines that make you sleepy (such as cold medicine, pain medication, muscle relaxers, and medicine for seizures, depression or anxiety), or medicines that may cause restlessness (such as caffeine, stimulants, diet pills, and decongestants contained in over-the-counter cold medicines).
