Guidance

If today is rough, here's what helps.

Before going outside

Take your daily antihistamine 30 minutes before exposure. Nasal sprays work best with consistent daily use, not as-needed.

After coming inside

Rinse your face and hair if you've been out for a while; change clothes before sitting on upholstery. Saline rinse if congested.

When to call us

If symptoms are interfering with sleep, work, or your asthma is acting up — that's a sign your plan needs adjustment. Call (775) 359-5010, ext. 3, to book.
