Hi,

Welcome to HCM...

You have given very short history. Your photo shows macular erythematous lesions. It may be called Morbilliform drug eruptions.

Such lesions can after taking certain drugs. I would like to know what is the disease you have and what drug you have taken. Kindly give detailed history of your disease and the medicines you took.

However,I would like to give you some knowledge about such drug induced rash....

Morbilliform drug rash is the most common drug rash occurs due to hypersensitivity reaction. Many drugs can trigger such reaction, among them antibiotics are the most common group. The eruption may resemble rashes or exanthems caused by viral and bacterial infections.

It is also called maculopapular drug eruption or morbilliform exanthem.

Morbilliform drug eruptions are very common, comprising 95% of all drug-induced skin reactions.

-Beta-lactam antibiotics (penicillins, cephalosporins),
-antibiotic sulfonamides,
-allopurinol,
-anti-epileptic drugs
- nonsteroidal anti-inflammatory drugs (NSAID) ...commonly taken, and are the most common drugs to cause this.

However the list is very long and includes herbal drugs and natural therapies.

In this type of drug rash,the skin rash usually appears 1-2 weeks after starting the drug, but sometimes may occur up to 1 week after stopping the medicine. However on re-exposure to the culprit drug, skin lesions appear fast...within 1-3 days.

Remember..... a morbilliform skin rash in an adult is usually due to a drug, but in a child is more likely to be viral.

I hope you got my answer.

Thanks.

Brief Answer:
Drug induced rash

Detailed Answer:
Hi,

Welcome back...

The red Morbilliform rash on whole body except hands is more likely due to the drug verapamil you are taking. You consult your physician. He would change your medicine. There is no need to take treatment for the rash, but I prefer you seek physicians help and discuss about changing verapamil. The rash should disappear after discontinuing the verapamil.

I hope this would help you.

Thanks.
