Tell your prescriber or health care professional about all other medicines you are taking, including non-prescription medicines.

These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.
Mesoridazine may cause your skin to become more sensitive to the sun or ultraviolet light. If this reaction occurs, it can cause a severe sunburn and damage the skin. Keep out of the sun, or wear protective clothing outdoors and use a sunscreen (at least SPF 15). Do not use sun lamps or sun tanning beds or booths. Wear sunglasses to protect your eyes.
Avoid skin contact with injectable mesoridazine because a skin reaction called contact dermatitis can occur. This reaction can cause redness, itching, or blistering of the skin. If the skin is accidentally exposed to injectable mesoridazine, wash the affected area immediately. Seek medical care if necessary.
Mesoridazine can change the response of your body to heat or cold. Try not to get overheated. Avoid temperature extremes, such as saunas, hot tubs, or very hot or cold baths or showers. Dress warmly in cold weather.
If you experience dry mouth while taking mesoridazine, make sure to drink plenty of water. It may also be helpful to suck on sugarless hard candy or crushed ice. If your dry mouth is severe, ask your doctor about a saliva substitute.
You may get dizzy or drowsy. Do not drive, use machinery, or do anything that needs mental alertness until you know how mesoridazine affects you. Alcohol can increase dizziness and drowsiness. Avoid alcoholic drinks.
