Why this happens
Bactrim (co-trimoxazole) can sometimes increase the effect of certain medications or natural processes that lower blood sugar. Gly-Coramin contains glucose, but it also contains nikethamide, a stimulant. In some cases, the sulfonamide component of Bactrim can interfere with how the body handles blood sugar, potentially leading to unexpected drops.
What you should do
Back to contentsUse this combination with caution. If you have diabetes or problems with blood sugar, monitor your levels more frequently. Watch out for signs of low blood sugar, such as feeling shaky, sweaty, dizzy, or confused. If you feel unwell, contact your doctor or pharmacist.

Important precautions
Back to contentsSevere Skin Reactions
Stop taking Bactrim immediately and seek urgent medical help if you develop a skin rash, peeling, or mouth sores. These can be signs of rare but life-threatening skin reactions (Stevens-Johnson syndrome or toxic epidermal necrolysis).
Pregnancy (Third Trimester)
Do not take Bactrim if you are in the final weeks of pregnancy. It can cause a serious type of jaundice (kernicterus) in the newborn baby by displacing bilirubin in the blood.
Doping in Sport
Gly-Coramin contains nikethamide, which is a prohibited substance in competitive sports. It will result in a positive drug test during or out of competition.
Food and drink warnings
Back to contentsAlcohol
While rare, some people experience a 'disulfiram-like reaction' when mixing Bactrim with alcohol. This can cause flushing, nausea, palpitations, and breathlessness. It is best to avoid alcohol during treatment and for 48 hours after finishing the course.
Cafeína
Gly-Coramin contains a stimulant. Consuming high amounts of caffeine (found in coffee, tea, energy drinks, and chocolate) may increase the risk of side effects such as restlessness, racing heart, and tremors.
