Can I take Hydroxycarbamide and Hydroxychloroquine together?

Why this happens

These drugs have 'additive' effects on the bone marrow. Hydroxycarbamide is designed to slow down the production of blood cells, and hydroxychloroquine can sometimes cause this as a side effect. When used together, the impact on your immune system and blood count is much stronger.

What you should do

You must speak to your doctor before taking these two medicines together. If your doctor decides you need both, you will require very frequent blood tests to monitor your full blood count. Seek immediate medical help if you develop a fever, sore throat, unusual bruising, or extreme tiredness.
