Possible food and drug interactions with Trimox

There may be an increased risk of experiencing a rash as a side effect of Trimox if you are also taking allopurinol.

Trimox may decrease the removal of methotrexate from the body, increasing the risk of side effects. If you are taking methotrexate you should be well monitored by your doctor while you are taking a course of Trimox.

Probenecid increases the blood level of Trimox, and people taking probenecids may be prescribed a lower dose of Trimox.

Trimox may rarely alter the anti-blood-clotting effects of anticoagulant medicines such as warfarin. Your doctor may wish to monitor your blood clotting time while you are taking both medicines.

If you are taking a combined oral contraceptive pill there may be a very low risk that Trimox may make it less effective at preventing pregnancy. Although the risk of this is very low, the personal and ethical consequences of an unwanted pregnancy can be very serious. For this reason the Family Planning Association recommends that women taking combined oral contraceptives should use an extra method of contraception (eg condoms) while taking a short course of Trimox , and for seven days after finishing the course. If the seven days run beyond the end of a pill packet, a new packet should be started without a break (in the case of ED pills the inactive tablets should be omitted).
