Special Considerations
In deciding to use a medicine, the risks of using the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For clonidine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to clonidine. Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.

Clonidine has not been shown to cause birth defects in animal studies but may cause other problems. Before taking this medicine, make sure your doctor knows if you are pregnant or if you may become pregnant.
Breast-feeding
Clonidine passes into the breast milk. Because this medicine may cause serious side effects, breast-feeding is generally not recommended while you are using it.
Children
Although there is no specific information comparing use of clonidine in children with use in other age groups, this medicine is not expected to cause different side effects or problems in children than it does in adults. This medicine is usually used in children only when the pain is severe and other pain medicines did not help.
Older adults
Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of clonidine in the elderly with use in other age groups.
Other medicines
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary.

• Beta-adrenergic blocking agents (acebutolol [e.g., Sectral], atenolol [e.g., Tenormin], betaxolol [e.g., Kerlone], bisoprolol [e.g., Zebeta], carteolol [e.g., Cartrol], labetalol [e.g., Normodyne], metoprolol [e.g., Lopressor, Toprol-XL], nadolol [e.g., Corgard], oxprenolol [e.g., Trasicor], penbutolol [e.g., Levatol], pindolol [e.g., Visken], propranolol [e.g., Inderal, Inderal LA], sotalol [e.g., Betapace], timolol [e.g., Blocadren])-These medicines may increase the risk of harmful effects when clonidine treatment is stopped suddenly
