What are the risks of taking allopurinol?

Back to Allopurinol

Will it affect vaccinations?

You can have vaccinations while on allopurinol.

Can I drink alcohol while on allopurinol?

Alcohol increases the level of urate in the blood so it’s recommended that you should only drink alcohol in small amounts (maximum of 14 units per week for women and 21 units per week for men). You should discuss this with your doctor.

Does allopurinol affect fertility or pregnancy?

It’s rare for women to get gout before the menopause, but allopurinol is unlikely to affect fertility. However, we don’t know what effect allopurinol might have on an unborn baby, so you shouldn’t take it if you’re pregnant. If you’re planning a family or become pregnant while taking allopurinol you should discuss this with your doctor.

Does it affect breastfeeding?

Some allopurinol will pass into the breast milk  and we don't yet know how this might affect the baby. Therefore you shouldn’t breastfeed if you’re taking allopurinol.
