Spasfon (phloroglucinol 80 mg) is an antispasmodic used to relieve familiar functional cramps, such as irritable bowel cramps and menstrual cramps. Its safety profile is clean in terms of side effects and interactions. However, it is not suitable for new, undiagnosed acute abdominal pain, which needs medical assessment before any sedation.
Many people look for Spasfon when abdominal cramps strike them suddenly or when cramps occur with their period, and they want to know what it does and what its limits are. The short answer is that it relaxes muscle spasms and does not treat the cause of the pain. That is why knowing the type of pain is just as important as knowing the medicine. In this article we explain its uses, warnings, and red-flag signs, and show you how to reach the right doctor in Jordan.
What is Spasfon and why is it used?
Spasfon (Spasphon) is the brand name for the active ingredient phloroglucinol (Phloroglucinol). It comes as tablets containing 80 mg and is classified in the drug directory among digestive system medicines. You can find its full profile on the Spasfon page in the drug directory.
It is usually prescribed for functional cramps, meaning pain caused by spasms of the muscles of a passage or organ without obvious acute inflammation. It is not subject to the strict controls that apply to narcotic drugs. The Jordan Food and Drug Administration (JFDA) regulates medicines and their listed prices in Jordan, so ask your pharmacist for the official price of the pack.
How does Spasfon work on cramps?
The walls of the intestines, the bile ducts, the ureters, and the uterus are built from smooth muscle. When these muscles contract strongly or irregularly, you feel pain that comes in waves. An antispasmodic works by relaxing these muscles, so the intensity of the contraction decreases.
It does not belong to the anticholinergic class. Therefore, it does not cause drowsiness or dry mouth as some other colic medicines do, according to the drug directory. This is understood especially in the context of the uterus: period pain occurs when the uterus contracts during menstruation, and it is usually a normal part of the menstrual cycle [2].
Relaxing the muscle eases the symptom but does not remove the cause. If the pain is due to inflammation, a stone, or an obstruction, the pain may partly subside while the disease keeps progressing without you noticing.
When is Spasfon used?
The drug directory lists the conditions for which it is usually prescribed. The following table summarizes its role in each case and what to pay attention to.
| Condition | Role of Spasfon | Important note |
|---|---|---|
| Irritable bowel syndrome and intestinal colic | Relieves known recurrent cramping | If colic recurs without a diagnosis, what is needed is investigation, not successive packs |
| Biliary colic | An adjunct that relaxes the duct | Severe, prolonged pain needs medical assessment |
| Renal or ureteric colic | Given alongside a painkiller | An adjunct to painkillers, not a replacement for them |
| Spasmodic dysmenorrhea (period pain) | Relieves cramps | Pain more severe than usual needs a doctor |
| Cramps in pregnancy and labor | Used within selected medical settings | Not to be used without a doctor's supervision |
What these conditions have in common is that they are "familiar": pain you recognize and understand the pattern of, or pain your doctor has previously diagnosed. New, different pain has a different story, which we will detail later.
Does Spasfon help with menstrual period pain?
Period pain is very common. It usually appears in the lower abdomen before or at the start of the period. It may be cramps that extend to the back and thighs, or sharp or mild continuous pain, and it usually lasts up to 3 days [2]. Spasfon is used here because the pain is caused by uterine contraction.
There are home measures that complement any medical treatment [2]:
- A warm bath or shower.
- A heat pack or a hot water bottle wrapped in cloth placed on the abdomen.
- Massage of the abdomen and back.
- Light exercise such as walking, swimming, or yoga.
- Painkillers such as paracetamol or ibuprofen.
For severe pain, a doctor may prescribe anti-inflammatory drugs such as naproxen or mefenamic acid, or hormonal contraceptives that lighten the period and reduce pain [2]. According to the drug directory, Spasfon can be combined safely with painkillers.
When is usual period treatment not enough?
See your doctor if your period becomes more painful, heavier, or irregular, if the pain prevents your daily activities, if it is accompanied by pain during intercourse, urination, or bowel movements, or by bleeding between periods [2]. Also see a doctor if you have abdominal swelling, loss of appetite, or unexplained weight loss [2].
Sometimes the pain may be due to endometriosis, uterine fibroids, or pelvic inflammatory disease. Tests such as ultrasound imaging may be done to find the cause [2]. An intrauterine device (IUD) may also cause pain during the first three to six months after insertion [2].
Does Spasfon have side effects or interactions?
Its profile is described as one of the cleanest in the pharmacy. Side effects are rare, the most important being a skin reaction (rash or hives), which requires stopping the drug and consulting a doctor. Very rare individual cases of angioedema, a sudden swelling of the face or lips, have been recorded. If swelling or shortness of breath appears, call 911 or go to the nearest emergency department. You can read more about drug allergy.
No significant documented drug interactions exist, and it can be safely combined with painkillers and antibiotics. Nevertheless, tell your pharmacist about everything you take. You can understand the difference between the two in the difference between a drug interaction and side effects.
And during pregnancy?
The drug directory classifies it under pregnancy category B, and it is used for cramps in pregnancy and labor within selected medical settings. However, this does not mean you should treat your abdominal pain yourself during pregnancy. Abdominal pain during pregnancy requires an urgent appointment or medical help [1].
What is the usual dose and how is it used?
The usual adult dose, as determined by the doctor or pharmacist, is two tablets two to three times daily, according to the drug directory. Do not exceed what has been prescribed for you, and do not extend the duration on your own.
As for children, their dose depends on weight and requires a doctor's prescription or pharmacist's guidance. Do not give a child the adult dose.
The directory notes that there is a dissolving sublingual form, which is useful when colic strikes you outside the home without water. However, if colic recurs without a diagnosis, do not keep buying packs; see a doctor.
When is sedation alone not acceptable? Warning signs
The rule with all antispasmodics is that new, acute, undiagnosed abdominal pain should be assessed before it is sedated. Early sedation may mask the picture of appendicitis, acute gallbladder disease, or obstruction. Pain severity is not the only criterion: severe pain does not always mean a serious problem, and mild pain does not mean it is trivial [3].
Call 911 or go to the nearest emergency department immediately if:
- The pain started suddenly and was severe or sharp [1][3].
- You vomited blood, or the vomit was green or resembled coffee grounds [1].
- A large amount of blood came from the anus, or the stool was black and sticky [1].
- You are unable to urinate at all, or unable to pass stool or wind at all [1].
- The abdomen was hard and rigid and painful to touch, or the pain was accompanied by pain in the chest, neck, or shoulder [3].
- A rash appeared that does not fade when pressed, or you have difficulty breathing [1].
Request an urgent appointment with a doctor if:
- The pain suddenly increased and became much worse [1].
- You are pregnant [1].
- Blood was found in the stool, or there is unusual bleeding or abnormal vaginal discharge [1].
- Diarrhea or vomiting has continued for more than a few days [1].
- Period pain was more severe than usual and painkillers did not help [2].
How do you tell some causes apart?
Do not diagnose yourself, but these are patterns that doctors recognize [1]:
- Lower right abdominal pain: may indicate appendicitis. This is a clear example of pain that should not be sedated but examined first, especially with fever or vomiting.
- Severe pain radiating toward the groin with nausea and pain on urination: may be a kidney stone. See renal colic treatment, and remember that here Spasfon is an adjunct to painkillers, not a replacement, and that drinking water and treating the stone are the foundation.
- Severe pain lasting up to 8 hours in the middle of the abdomen or under the right ribs: may be gallstones.
- Recurrent pain with bloating and diarrhea or constipation: may be associated with irritable bowel syndrome.
For severe pain in the upper abdomen, read about acute pancreatitis. If the pain is accompanied by persistent nausea and vomiting, see nausea and vomiting and when to be concerned.
What if the pain recurs or lasts a long time?
See a doctor if abdominal pain, bloating, indigestion, or recurrence continues [1], or if you feel a lump in your abdomen or are worried about your symptoms [1]. If mild pain persists for a week or more, or is accompanied by other symptoms, contact your healthcare provider [3].
A doctor may order tests such as ultrasound or endoscopy depending on the case [3]. To understand chronic pain in depth, read about chronic abdominal pain beyond irritable bowel syndrome.
If there is blood in the stool or a persistent change in bowel habits, a doctor may suggest a colonoscopy. You can find information about the colon, colonoscopy, and colorectal cancer.
How do you find the right doctor in Jordan?
The specialty follows the type of pain, and you can start from the abdominal pain symptom page in the directory:
- Period and pregnancy pain: obstetrics and gynecology.
- Intestinal or colon colic: internal medicine or gastroenterology.
- Renal colic: urology or internal medicine.
- If you do not know the specialty, start with a general practitioner or one of the Ministry of Health primary health centers spread across the governorates. For women and children, maternal and child health centers are available.
Filter your search by the governorate that suits you, then open the doctor's profile and check:
- The listed specialty and years of experience.
- The clinic location and working hours.
- The contact or booking method available, if the profile allows it.
Before the appointment, prepare your questions:
- What is the likely cause of the pain, and do I need tests?
- Is an antispasmodic suitable for me, at what dose and for how long?
- What symptoms mean I should return immediately or go to the emergency department?
Write down when the pain started, where it is, what makes it worse or better, and any medications you take, as this information saves a lot of time.
Summary: how do you use Spasfon safely?
- Spasfon relaxes cramps and does not treat the cause of the pain.
- It suits familiar colic such as irritable bowel cramps or menstrual cramps, not new and different pain.
- Its side effects are rare, but a rash or swelling requires stopping it and consulting a doctor.
- The dose and duration are determined by the doctor or pharmacist, and for children, by weight and with a prescription.
- Pregnancy, fever, vomiting, blood, pain in the lower right abdomen, or pain that suddenly intensifies all mean assessment before sedation, and with severe acute pain, call 911.

Frequently asked questions
Does Spasfon stop period pain?
Spasfon helps relax the uterine contractions that cause period pain, and it can be safely combined with painkillers. However, it does not treat any underlying cause such as uterine fibroids or endometriosis. If the pain is more severe than usual or the treatment does not help, see a gynecologist to determine the cause.
Does Spasfon cause drowsiness or dry mouth?
No. According to the drug directory, it does not cause drowsiness, dryness, or anticholinergic effects. Its side effects are rare, the most important being a skin reaction such as a rash or hives, in which case it should be stopped and a doctor consulted. If the face or lips swell or breathing becomes difficult, go to the emergency department immediately or call 911.
Can Spasfon be taken with painkillers or antibiotics?
No significant documented drug interactions exist, and according to the drug directory it can be safely combined with painkillers and antibiotics. Nevertheless, it is preferable to tell your pharmacist or doctor about all your medicines and supplements before starting, especially if you have chronic illnesses or are pregnant.
What is the usual Spasfon dose for adults and children?
The usual adult dose, as determined by the doctor or pharmacist, is two tablets (80 mg per tablet) two to three times daily.
