Precautions While Using This Medicine

Your doctor should check your progress at regular visits, especially during the first few months of treatment with this medicine. The amount of haloperidol you take may be changed often to meet the needs of your condition. This also helps prevent side effects.

Do not stop taking this medicine without first checking with your doctor . Your doctor may want you to reduce gradually the amount you are taking before stopping completely. This will allow your body time to adjust and help avoid a worsening of your medical condition.

This medicine will add to the effects of alcohol and other CNS depressants (medicines that slow down the nervous system, possibly causing drowsiness). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; barbiturates; medicine for seizures; muscle relaxants; or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the above while you are taking this medicine .

This medicine may cause some people to become dizzy, drowsy, or less alert than they are normally, especially as the amount of medicine is increased. Even if you take haloperidol at bedtime, you may feel drowsy or less alert on arising. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert .

Although not a problem for many patients, dizziness, lightheadedness, or fainting may occur, especially when you get up from a lying or sitting position. Getting up slowly may help. However, if the problem continues or gets worse, check with your doctor.

This medicine will often make you sweat less, causing your body temperature to increase. Use extra care not to become overheated during exercise or hot weather while you are taking this medicine, since overheating may result in heat stroke . Also, hot baths or saunas may make you feel dizzy or faint while you are taking this medicine.

Before using any prescription or over-the-counter (OTC) medicine for colds or allergies, check with your doctor. These medicines may increase the chance of heat stroke or other unwanted effects, such as dizziness, dry mouth, blurred vision, and constipation, while you are taking haloperidol.

Before having any kind of surgery, dental treatment, or emergency treatment, tell the medical doctor or dentist in charge that you are using this medicine . Taking haloperidol together with medicines that are used during surgery or dental or emergency treatments may increase the CNS depressant effects.

Haloperidol may cause your skin to be more sensitive to sunlight than it is normally. Exposure to sunlight, even for brief periods of time, may cause a skin rash, itching, redness or other discoloration of the skin, or a severe sunburn. When you begin taking this medicine:

• Apply a sun block lipstick that has an SPF of at least 15 to protect your lips.
• Do not use a sunlamp or tanning bed or booth.

If you have a severe reaction from the sun, check with your doctor .

Haloperidol may cause dryness of the mouth. For temporary relief, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if your mouth continues to feel dry for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.
