Can You Cut Bactrim DS Tablets in Half?

Hello, and thanks for using HelloPharmacist!

Yes, you can absolutely use a pill cutter to split your Bactrim DS tablet in half to make it easier to swallow. That indentation you noticed down the middle of the tablet is called a score line, and it's the manufacturer's way of indicating the tablet is designed to be broken evenly.

Bactrim DS tablets are quite large (they contain 800 mg of sulfamethoxazole and 160 mg of trimethoprim), so you're certainly not the first person to find them a challenge to get down!

Why the Score Line Makes Splitting Okay

Two things make Bactrim DS a good candidate for splitting.

First, it's an immediate-release tablet, meaning there's no special extended-release or delayed-release mechanism inside that could be disrupted by cutting it.

Second, that score line means the tablet was manufactured with breaking in mind, so you should get two reasonably even halves. Compare that to unscored or film-coated tablets, where splitting can produce uneven pieces or expose a bitter interior, and you're in a much better position with Bactrim DS.

Since you're splitting purely to make swallowing easier (not to change your dose), just be sure to take both halves at the same time so you get the complete dose your doctor prescribed.

Tips for Cutting and Taking Your Tablets

Here are some pointers I usually give to individuals who need to split tablets:

• Use a clean, sharp pill cutter and line the score mark up with the blade for the most even cut.
• Split each tablet right before you take it rather than cutting the whole bottle at once (i.e., don't split all the tablets and store for later use).

If even the halves are hard to manage, ask your pharmacist or doctor about the liquid (oral suspension) form of sulfamethoxazole-trimethoprim, which avoids swallowing tablets altogether.
