What is Dapsone?

Dapsone is an oral medication indicated to treat dermatitis herpetiformis. It is also used for leprosy or Hansen’s disease as an adjunct to other antileprotic agents. This medication does not work for infections caused by viruses.

This sulfone is known to have both bactericidal and bacteriostatic actions. It works by inhibiting the synthesis of dihydrofolic acid by competing with para-amino-benzoate for the active site of dihydropteroate synthetase. This medication’s anti-inflammatory effect is not related to its antibacterial action and is still unknown.

This is available in Dapsone 100mg and 25mg tablet forms.

How to use Dapsone

The package comes with a medication guide or information leaflet so make sure to read it before using the medication. Do not use this prescription medication yet if you have not fully understood the instructions and drug information in the guide provided. If you need more medical advice or have some queries on how to use this drug properly, ask your doctor or pharmacist.

Take the tablet orally. This is usually prescribed once daily or as directed by your physician. The drug can be taken either with or without food. Swallow the tablet and drink a glass of water right after. It is not recommended to split, cut, crush, or chew this type of medication.

Remember to take this oral drug regularly and exactly as directed. To avoid skipping a dosage, create a dosing schedule. If you are taking antacids, ranitidine, famotidine, or didanosine, separate them from your Dapsone dosage for at least 2 hours. This is because these medications may prevent full absorption of sulfone and reduce its effectiveness.

Do not alter your dosing as it depends on your medical condition, response to treatment, age, and weight. Also, you must not stop using this medication abruptly to avoid worsening conditions.
