How quickly can Everyday Rx cold sore, herpes, or allergy medication work?

There is no single timeline for all Everyday Rx treatments. The active ingredient, type of symptoms, and how long you have had them all matter. Results vary. Your physician can explain what to expect from the specific medicine prescribed for you.

For cold sores or genital herpes, antiviral treatment often works best when started early in an outbreak. Early signs can include tingling, burning, or itching before sores appear. Follow the start instructions on your prescription rather than taking extra medicine to try to speed things up. Results vary.

For allergies, some medicines can begin easing symptoms relatively soon after a dose. Other treatments, including some nasal medicines, need steady use before their full effect can be judged. Results vary. Do not assume a medicine has failed after one dose unless your physician tells you that is the right test.

Ask when to follow up if symptoms are unchanged or getting worse. Seek prompt care for eye symptoms, severe pain, or signs of a serious allergic reaction instead of waiting for routine treatment to work.
