Brief Answer:
Drug induced pruritus

Detailed Answer:
Hello,

Welcome to healthcare magic forum.

I understand from your query that you are having itching after taking sulphamethoxazole / trimethoprim tablets.

The itching could be related to drug intake.

From your history, you do not seem to having any rash.

Sulpha group of drugs are common causative agents of drug rash.

You could continue taking Benadryl tablet at bedtime.

You can take a non-sedative antihistamine like Loratidine ( Claritin) orally in the morning.

If the itching does not stop even after 2 days of antihistamines, you may need a short course of a small dose of oral steroids ( like prednisolone 0.5 mg /kg body weight) for 3-5 days. You need to get this prescribed by your GP.

Hope this helps you.

If you have any more queries, I will be glad to help.

Take care.

Regards,
Dr. Johny Chacko
