Tofacitinib 5 mg Tablet — IEB Pharmacy

Tofacitinib 5 mg tablets (sold under different brand names depending on where you are) treat certain inflammatory and immune-related diseases. It’s a prescription drug, part of a group called Janus kinase (JAK) inhibitors, which basically dial down an overactive immune system.

What is Tofacitinib?

Tofacitinib is a small molecule drug that messes with specific signaling pathways in immune cells. You take it as a tablet. Usually, doctors turn to it if other meds haven’t worked or if someone can’t tolerate those other options. The “5 mg” just refers to how much medicine is in each tablet.

Researchers first developed the Tofacitinib 5 mg tablet while studying autoimmune diseases—those are the conditions where your immune system turns against your own body, causing damage and inflammation, like in your joints or gut. Tofacitinib helps slow this misguided attack, so inflammation, pain, and tissue damage can calm down over time.

How does it work?

Inside your cells are enzymes called Janus kinases (JAKs). They relay signals from outside the cell—often from molecules called cytokines—into the cell’s nucleus, triggering immune responses and inflammation.

Tofacitinib blocks certain JAKs, especially JAK1 and JAK3. This action keeps the immune system from overreacting. By slowing down these pathways, tofacitinib reduces inflammation—the redness, swelling, and pain you see in things like arthritis or ulcerative colitis.

What do people use it for?

The active ingredient, tofacitinib 5 mg, is mainly prescribed for:

Rheumatoid Arthritis (RA): A chronic disease where the immune system attacks the joints. Tofacitinib helps cut down pain, stiffness, swelling, and joint damage by quieting the immune system.

Psoriatic Arthritis (PsA): Another joint problem connected to psoriasis. If other treatments haven’t worked, tofacitinib can help.

Ulcerative Colitis (UC): An inflammatory disease of the colon that causes diarrhea, bleeding, and cramps. For moderate to severe cases, tofacitinib helps settle the inflammation.

Sometimes doctors try it for other conditions, but these are the main ones it’s approved for. Usually, a specialist prescribes it, and you’ll keep taking it as long as it’s working for you.

How do you take tofacitinib?

You swallow tofacitinib 5 mg tablets, usually 5 mg twice a day, but your doctor sets the dose based on your condition. You can take it with or without food. Just don’t chew or crush the tablets—swallow them whole, ideally at the same times every day to keep the drug level steady. Don’t change your dose or stop the medicine without talking to your doctor first.

Doctors often want regular blood tests to check how your body’s handling the medicine and to watch for side effects, especially if you’re on it for a while.

Possible side effects

Like any drug, Tofacitinib 5 mg price can cause side effects. Some of the more common ones:

Upper respiratory infections (like catching a cold)

Headache

Diarrhea

Nausea

Mild skin rash

Feeling tired

Usually, these are pretty mild and go away on their own.

But since tofacitinib dampens your immune system, it can make you more likely to get infections, like shingles or even tuberculosis, especially if your immune system’s already weak. Rarely, it can mess with your blood counts or liver enzymes, or even cause blood clots. That’s why your doctor keeps a close eye on you during treatment.

A few things to keep in mind

Because tofacitinib affects your immune system, here are some things you need to know:

You need a prescription. Only take it if your doctor says so, and stay under medical supervision.

Watch for infections. If you get a fever, sore throat, cough, or just feel wiped out, let your doctor know.

Vaccines are tricky. Live vaccines usually aren’t recommended while you’re on tofacitinib.

Drug interactions. Other meds that affect your liver (like some antifungals or antibiotics) can interact with tofacitinib.

Not for everyone. People with serious liver or kidney problems, or low blood cell counts, might not be able to take it.

Pregnancy and breastfeeding. If you’re pregnant, planning to be, or breastfeeding, talk this over with your doctor.

How to store it

Keep tofacitinib 5 mg tablets in a cool, dry spot—out of direct light and moisture. And, as always, keep them out of reach of kids.
