How should I take Sectral?

Follow all directions on your prescription label. Your doctor may occasionally change your dose to make sure you get the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.

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

Your blood pressure will need to be checked often.

You should not stop using Sectral suddenly. Stopping suddenly may make your condition worse.

If you are being treated for high blood pressure, keep using this medicine even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medicine for the rest of your life.

Sectral is only part of a complete treatment program that may also include diet, exercise, and weight control. Follow your doctor's instructions very closely.

Store at room temperature away from moisture, heat, and light.

Keep the bottle tightly closed when not in use.

What happens if I miss a dose?

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

Overdose symptoms may include very slow heartbeats, trouble breathing, severe dizziness, fainting, or seizure (convulsions).

Drinking alcohol with Sectral can cause side effects.

Ask a doctor or pharmacist before using any cough or cold medicine that contains a decongestant. Taking Sectral together with a decongestant may raise your blood pressure to dangerous levels.

This medicine may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
