Although you may feel better early in treatment, Dapsone should be used exactly as directed. Misuse or overuse of Dapsone could lead to the growth of bacteria that will not be killed by Dapsone (resistance). This means that Dapsone may not work for you in the future. Do not share your medicine.

Warnings and precautions
To help avoid side effects and ensure proper use, talk to your healthcare professional before you take DAPSONE. Talk about any health conditions or problems you may have, including if you have:
- heart problems
- lung disease
- liver disease
- kidney problems
- anemia
- lack of the enzyme glucose-6-phosphate dehydrogenase in the body, so that red blood cells don’t work properly.
DAPSONE may cause blood cell problems such as:
- Hemolytic anemia - red blood cells are destroyed so that they do not do their job carrying oxygen in the body
- Methemoglobinemia – where a high amount of methemoglobin is made in the blood, and this prevents oxygen release into body tissues
- Lack of the enzyme glucose-6-phosphate dehydrogenase can worsen the above blood cell problems.
Your doctor will do routine blood work during DAPSONE treatment to watch for blood problems and changes in liver function.
Other warnings you should know about:
Don’t use DAPSONE while pregnant unless advised by your doctor. If you become pregnant
while taking DAPSONE, tell your doctor immediately
DAPSONE is excreted in breast milk. Your doctor will decide with you if you should continue breastfeeding or stop taking DAPSONE.
Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.
