What is a ZC25 Pill?
A yellow, round tablet with the imprint 'ZC 25' is identified as Meloxicam 7.5 mg [1.2.1, 1.2.3]. Contrary to what some might assume from a search for cold medications, this is not a cough suppressant or an antihistamine. Instead, Meloxicam is a prescription non-steroidal anti-inflammatory drug (NSAID) [1.2.1]. It is primarily used to manage the symptoms of various forms of arthritis, such as osteoarthritis and rheumatoid arthritis [1.2.3, 1.2.7]. The 'ZC 25' marking is an identifier used by the manufacturer, Zydus Pharmaceuticals [1.2.3].
How Meloxicam (ZC25) Works
Meloxicam functions by inhibiting the cyclooxygenase (COX) enzymes in the body. These enzymes are responsible for producing prostaglandins, which are hormone-like substances that cause inflammation and pain [1.2.7]. By reducing the production of prostaglandins, Meloxicam helps to alleviate pain, swelling, and stiffness in the joints associated with arthritis [1.2.7]. It is important to use the lowest effective dose for the shortest possible duration to achieve treatment goals and minimize risks [1.2.3].
Primary Uses and Dosage
Healthcare providers prescribe ZC25 (Meloxicam 7.5 mg) for the following conditions:
- Osteoarthritis (OA): This is a degenerative joint disease and the most common form of arthritis [1.2.1, 1.2.7].
- Rheumatoid Arthritis (RA): An autoimmune disorder that causes inflammation in the joints [1.2.1, 1.2.3].
- Juvenile Rheumatoid Arthritis (JRA): A form of arthritis that occurs in children [1.2.1].
The typical starting dose for adults with osteoarthritis or rheumatoid arthritis is 7.5 mg once daily. Depending on the patient's response, a doctor might increase the dosage to 15 mg once daily, which is the maximum recommended daily oral dose [1.2.3]. The medication can be taken without regard to meals [1.2.3].
Potential Side Effects and Black Box Warning
Like all NSAIDs, Meloxicam carries significant risks, which are highlighted in an FDA-mandated 'black box warning' [1.2.3].
FDA Black Box Warning
- Cardiovascular Risk: NSAIDs like Meloxicam can increase the risk of serious and potentially fatal cardiovascular events, such as heart attack and stroke. This risk may be higher for those with existing heart disease or who use the medication for a long time [1.2.3].
- Gastrointestinal Risk: NSAIDs can also increase the risk of serious gastrointestinal problems, including bleeding, ulceration, and perforation of the stomach or intestines. These events can occur without warning and may be fatal, with elderly patients being at a higher risk [1.2.3].
Common Side Effects
More common side effects are generally milder and may include:
- Diarrhea [1.2.3]
- Dyspepsia (indigestion) [1.2.3]
- Headache [1.2.3]
- Nausea [1.2.3]
- Upper respiratory tract infections [1.2.3]
Serious Side Effects
Patients should seek immediate medical attention if they experience any of the following:
- Chest pain, shortness of breath, or weakness on one side of the body.
- Signs of stomach bleeding like black, bloody, or tarry stools, or coughing up blood.
- Skin rash, blistering, or peeling [1.2.3].
- Unexplained weight gain or swelling (edema) [1.2.3].
- Signs of liver problems, such as jaundice (yellowing of the skin or eyes) [1.2.3].
Drug Interactions and Precautions
Meloxicam can interact with numerous other medications. It is crucial to inform your doctor of all medications you are taking. Key interactions include:
- Other NSAIDs (e.g., aspirin, ibuprofen, naproxen): Combining NSAIDs increases the risk of gastrointestinal bleeding [1.2.3].
- Anticoagulants (e.g., warfarin): Concurrent use can increase the risk of bleeding complications [1.2.3].
- ACE Inhibitors and Diuretics: Meloxicam may reduce the blood pressure-lowering effects of these drugs [1.2.3].
- Lithium: Meloxicam can increase lithium levels in the blood [1.2.3].
This medication should not be used in patients with a known hypersensitivity to Meloxicam, or in those who have experienced asthma or severe allergic reactions after taking aspirin or other NSAIDs [1.2.3]. It is also contraindicated for pain management in the setting of coronary artery bypass graft (CABG) surgery [1.2.3].

| Mechanism | Reduces inflammation and pain | Reduces inflammation and pain | Reduces pain and fever | Blocks pain signals in the CNS [1.4.2] |
| Prescription? | Yes [1.2.7] | No (OTC) | No (OTC) | Yes [1.4.2] |
| Primary Use | Arthritis, chronic joint pain [1.2.1] | Mild-to-moderate pain, fever | Pain, fever | Moderate pain, cough [1.4.2] |
| GI Risk | Yes (Boxed Warning) [1.2.3] | Yes | Low | Low (but causes constipation) [1.3.6] |
| Addiction Risk | No | No | No | Yes [1.4.1] |
Conclusion
The pill marked 'ZC 25' is identified as Meloxicam 7.5 mg, a prescription NSAID used for managing arthritis, not for treating coughs [1.2.1, 1.2.3]. While effective for pain and inflammation, it carries serious cardiovascular and gastrointestinal risks highlighted in its black box warning [1.2.3]. Patients should only use this medication under the guidance of a healthcare professional, ensuring they understand the potential side effects and drug interactions. Always confirm the identity and purpose of any medication with a pharmacist or doctor.
