Can I take Abiraterone and Doxycycline together?

Why this happens

Abiraterone and doxycycline are processed by different pathways in the liver and do not significantly interfere with each other's absorption or effectiveness.

You can take these two medicines together. Ensure you follow the specific timing instructions for abiraterone (usually taken on an empty stomach). If you have been prescribed a steroid alongside abiraterone, inform your doctor before starting the course of doxycycline.

Pregnancy and contraception

Abiraterone can cause severe birth defects. Men must use a condom and another effective method of contraception during treatment and for 3 months after stopping if their partner is pregnant or could become pregnant.

Sun exposure

Doxycycline makes your skin much more sensitive to sunlight. You must avoid direct sunlight and sunbeds, and use a high-factor sunscreen (SPF 50) to prevent severe skin reactions and burning.

Heart and liver monitoring

Abiraterone can cause high blood pressure, fluid retention, and liver damage. You must have regular blood tests and blood pressure checks as directed by your specialist.
