Spadix Injection is a combination medication that works as both an antispasmodic and an analgesic. That means it helps relax muscles and relieve pain at the same time. It is commonly used to treat painful spasms, especially those related to the abdomen, pelvis, or uterus.
This injection usually contains two key components:
- Phloroglucinol – a muscle relaxant that eases spasms.
- Trimethylphloroglucinol – enhances the antispasmodic effect and supports pain relief.
During pregnancy, women may experience mild to moderate abdominal cramps, uterine spasms, or pelvic discomfort, especially in the early or mid stages. Doctors may prescribe Spadix Injection to help manage such issues, especially when:
- Uterine cramps are causing distress.
- There’s pain without bleeding, often labeled as harmless pregnancy cramps.
- The mother is dealing with gastrointestinal spasms or discomfort.

Spadix Injection Formula / Composition
Spadix Injection is a powerful yet gentle combination of two main active ingredients:
Ingredient | Role in the Body |
---|---|
Phloroglucinol | Relaxes smooth muscles, especially in the uterus and digestive tract. |
Trimethylphloroglucinol | Boosts the antispasmodic effect, giving faster and longer-lasting cramp relief. |
Together, they soothe muscle spasms and reduce pain, especially in conditions where the uterus or abdominal muscles tighten abnormally.
How Does Each Component Work?
- Phloroglucinol works by directly relaxing involuntary muscles, like those found in the uterus or intestines. It doesn’t affect your central nervous system, which makes it safer for pregnant women under medical supervision.
- Trimethylphloroglucinol is a more potent derivative of phloroglucinol. It strengthens the spasm-relieving action and gives faster pain relief, especially in acute situations like sudden cramps during pregnancy.
Spadix Injection Route
Spadix Injection is available in two injectable forms:
Route | When It’s Used |
---|---|
IV (Intravenous) | Injected directly into the vein for rapid relief, often in emergency settings. |
IM (Intramuscular) | Injected into the muscle for a slightly slower but longer-lasting effect. |
Doctors choose the route based on the urgency of the condition and the patient’s comfort or situation.
Dosage Form – What Does It Look Like?
Spadix is typically available in the form of glass ampoules, each containing a single dose of the medication. These are meant to be administered by a healthcare provider, not for self-injection.
Spadix Injection Strength
Each ampoule of Spadix Injection commonly contains:
- Phloroglucinol – 40 mg
- Trimethylphloroglucinol – 0.04 mg
This combination is balanced to provide quick relief from spasms without overwhelming your system, which is particularly important during pregnancy.

Is Spadix Injection Safe in Pregnancy?
Safety is the first concern for any expectant mother — and rightly so. If your doctor has recommended Spadix Injection during your pregnancy, you’re probably wondering: “Is this really safe for me and my baby?”
Safety Classification
Spadix Injection (Phloroglucinol + Trimethylphloroglucinol) does not have an official FDA pregnancy category, but it is generally considered safe when used under medical supervision, especially during the first and second trimesters.
Here’s a trimester-wise overview:
Trimester | Safety Notes |
---|---|
First Trimester | Can be used to relieve early pregnancy cramps, but only if prescribed by a doctor. |
Second Trimester | Often prescribed for managing uterine spasms and abdominal pain. |
Third Trimester | Used cautiously; not typically recommended close to labor without medical need. |
Clinical Considerations
Doctors typically consider Spadix safe in pregnancy when:
- The mother is experiencing recurrent uterine cramps or spasms.
- There’s no bleeding or signs of miscarriage.
- Other causes of pain (like infections or preterm labor) have been ruled out.
- A short-term, quick-relief option is needed to avoid oral medications.
Avoid If You Have… | Reason |
---|---|
Allergy to phloroglucinol or similar compounds | May trigger allergic reactions. |
Ongoing vaginal bleeding or miscarriage symptoms | It could mask the signs of complications. |
Severe liver or kidney problems | Metabolism of the drug may be affected. |
Near term (late third trimester) without cause | It could interfere with labor timing in rare cases. |
Expert Opinions / Gynecologist Views
Many gynecologists in Pakistan and globally use Spadix Injection as a first-line antispasmodic in pregnancy-related pain. Here’s what doctors typically say:

— Dr. Maria Hussain, Consultant Gynecologist

If your pregnancy is considered high risk (e.g., history of preterm labor, placenta problems), your doctor will carefully weigh the benefits and risks before recommending Spadix. - Breastfeeding mothers:
There is limited data on whether Spadix passes into breast milk. It’s best to discuss with your doctor if you are breastfeeding before using this injection.
