What is Stanback?

Stanback is a combination medicine for adults and children who are at least 12 years old.

Adults may also use it to help with hangover symptoms.

Stanback should not be used instead of getting sleep.

Stanback may also be used for other reasons that are not mentioned in this guide.

How should I take Stanback?

Use exactly as directed on the label, or as prescribed by your doctor.

Stanback is usually taken every 6 hours with a full glass of water.

Take with food if Stanback upsets your stomach.

Limit the use of caffeine-containing medications, coffee, tea, cola, energy drinks, or other sources of caffeine while taking this product.

Call your doctor if your symptoms do not improve, or if they get worse.

If you need surgery, tell the surgeon ahead of time that you are using Stanback. You may need to stop using the medicine for a short time.

Store at room temperature away from moisture and heat.

Warnings

Aspirin may cause bleeding in the stomach or intestines, which can be deadly.

Aspirin can also lead to a severe allergic reaction. Seek emergency medical help if you experience signs of an allergic reaction: hives, trouble breathing, swelling of your face, lips, tongue, or throat.

While taking Stanback, limit the use of medications that contain caffeine, as well as coffee, tea, cola, energy drinks, or other caffeine sources. Too much caffeine may lead to nervousness, irritability, trouble sleeping, and rapid heartbeats.
