Most people take this drug to treat common cold, allergies, or common irritations occurring on a yearly basis.

For pregnant women, the topic of medication is often debatable as many medications are usually considered unsafe to take while pregnant. In addition, it is recommended to try to avoid medications during the initial stages of pregnancy.

Even then, you should only use them when necessary and in short durations. But, always practice caution when taking any medication, especially during pregnancy.
