TL;DR

• Menstrual cramps, medically known as dysmenorrhea, are common and can range from mild to severe. 

• They are usually caused by high levels of chemicals called prostaglandins or, in some cases, an underlying condition.[1]

• Home remedies like heat therapy, TENS, rest, or gentle movement may provide relief from pain, but medication may be needed if symptoms persist.[2,3]

• Nonsteroidal anti-inflammatory drugs (NSAIDs) are the first-line treatment for menstrual cramps.[4,5]

• Other medicines may also be recommended, depending on the cause and severity of symptoms. These include antispasmodics, hormonal treatments, analgesics, and neuromodulators.[6,7,8,9,10]

• Combining medication with supplements, heat therapy, TENS, and lifestyle changes may help manage symptoms better. It may also reduce the need for frequent medication over time.

• If pain does not improve with treatment, it may require further evaluation to rule out any underlying conditions.[1]

What Causes Period Cramps (Dysmenorrhea)?

Most women of reproductive age experience menstrual cramps at some point. The intensity can range from mild pain and discomfort to severe pain that affects daily activities. Menstrual pain is divided into two categories based on its root cause. 

Period pain due to high levels of prostaglandins (Primary dysmenorrhea)

Primary dysmenorrhea is menstrual pain that occurs without any underlying condition. Just before and during your period, the uterine lining releases prostaglandins. These hormone-like chemicals trigger uterine contractions needed for menstrual bleeding.[1]

When prostaglandin levels are higher, contractions become stronger and more frequent, leading to pain and cramping in the lower abdomen.  

The pain usually lasts 8–72 hours and eases as prostaglandin levels fall. Other common symptoms include lower back pain, thigh pain, headache, diarrhea, nausea, and vomiting.[1] 

Period pain due to an underlying condition (Secondary dysmenorrhea)

Secondary dysmenorrhea is menstrual pain caused by an underlying condition affecting the reproductive organs. Unlike primary dysmenorrhea, this type of pain often begins earlier, lasts longer, and may feel more intense.[1]

It is often associated with symptoms such as heavy menstrual bleeding, pelvic pain between periods, or pain during or after sex. Conditions such as endometriosis, pelvic inflammatory disease, uterine fibroids, or adenomyosis may cause this type of period pain.[1]

Note: This distinction matters because treatment depends on what is causing the pain. 

Can Period Pain Relief Medicines Help?

Painkillers are typically the first-line treatment for period pain, especially when no underlying condition is present.[1]

When medications can help

Medicines work best when the pain is caused by prostaglandins (primary dysmenorrhea) and follows a predictable pattern.

Signs that medicines may work well: 

• Pain starts just before or on day 1 of periods

• Crampy lower abdominal pain that may spread to the back or thighs

• Improves within 8–72 hours

• No major warning signs

Most women notice improvement within 1–2 cycles. Some may also benefit from combining it with heat therapy, TENS, or supplements.

Note: Medications are more likely to work when taken in the correct dosage at the right time, ideally at the first sign of pain or just before it begins. 

When medications alone may not be enough 

If an underlying condition such as endometriosis or fibroids is causing the pain (secondary dysmenorrhea), just painkillers may not be as effective.

Possible signs include:

• Pain that starts days before the period or continues after it ends

• Worsening pain over time

• Heavy or irregular bleeding

• Pain during intercourse or between periods

In these cases, further evaluation may be needed. Treatment often involves a combination of approaches.

Types of Medicines for Period Pain Relief

Various types of medicines may be used to manage period pain. The overview below explains how each type works, when it may be recommended, who should avoid it, and the possible side effects.

Disclaimer: Always consult a doctor before starting any medication for period pain. Self-medicating, taking the wrong dose, or continuing a medicine that is not working may cause side-effects or delay the diagnosis of an underlying condition.

NSAIDs (Non-steroidal anti-inflammatory drugs)

NSAIDs are the most commonly used first-line treatment to relieve menstrual cramps. They lower prostaglandin production, which helps reduce inflammation, pain, and abdominal cramps. They work well especially when taken early and at the correct dosage.[4,5]

Examples: Ibuprofen, mefenamic acid, diclofenac, aspirin

When your doctor may recommend it: For mild to moderate period pain, especially when symptoms are predictable and linked to the menstrual cycle.

Who should avoid it? Women with a history of stomach ulcers, gastrointestinal bleeding, kidney disease, severe liver disease, asthma, bleeding disorders, certain cardiovascular conditions, or allergy to NSAIDs should not take the medication without proper guidance. Pregnant or breastfeeding women should also consult their doctor first.[4,5]

Side effects: May cause nausea, stomach upset, heartburn, dizziness, drowsiness, headaches, and dryness of mouth. Less commonly, NSAIDs may lead to more serious side effects such as gastrointestinal bleeding or kidney issues.[4]

DRESS syndrome: The Indian Pharmacopoeia Commission has issued a warning about mefenamic acid. It may trigger a rare but serious reaction called DRESS syndrome (Drug Reaction with Eosinophilia and Systemic Symptoms). Early signs may include fever and a widespread rash, sometimes followed by facial swelling. In rare cases, it can affect internal organs if not treated in time. 

Although uncommon, it is important to be aware of these symptoms. Mefenamic acid should be taken under a doctor’s guidance, and medical help should be sought if any unusual symptoms develop.[11,12]

Antispasmodic drugs

Antispasmodic drugs work by relaxing the smooth muscle of the uterus. It helps in reducing the spasms and contractions that cause cramps and pain.[6]

Examples: Drotaverine, hyoscine butylbromide

When your doctor may recommend it: As an add-on to NSAIDs for faster and stronger relief. 

Who should avoid it? Those with a history of low blood pressure, severe liver or kidney disease, or certain heart conditions should discuss this with their doctor before use.

Side effects: May include nausea, dry mouth, dizziness, or constipation. In some cases, it may also cause a slight increase in heart rate.

Hormonal contraceptives

Hormonal contraceptives are often recommended when NSAIDs alone are not sufficient or when contraception is also needed. Two types are used: combined oral contraceptive and progestin.[7]

1. Combined oral contraceptives

Combined oral contraceptives contain both estrogen and progestin and often work better for period pain relief. They help suppress ovulation and reduce the thickness of the uterine lining, which may lower prostaglandin production. It helps relieve menstrual cramps and reduce heavy bleeding.[7]

When your doctor may recommend it: For period pain caused by higher prostaglandin levels or underlying conditions.[13,14,15,16]

Who should avoid it? Women with high blood pressure, breast or endometrial cancer, heart disease, migraines with aura, liver disease, a history of blood clots or stroke, blood clotting disorders, or two or more cardiovascular risk factors should avoid it. Smokers over the age of 35 should also avoid it. Postpartum or breastfeeding women should also discuss with a doctor before using it.[7]

Side effects: Usually mild side-effects that resolve with continued use or trying a different formulation. Breast tenderness, nausea, headaches, bloating, increased vaginal discharge, decreased libido, or bleeding between periods. Long-term risks may include an increased risk of clotting.[7,17]

2. Progestin

Progestins mimic the action of progesterone and work by thinning the uterine lining and reducing prostaglandin production. This can help reduce menstrual bleeding and ease pain.[8]

When your doctor may recommend it: For period pain with an underlying condition such as endometriosis or when estrogen is not suitable.[18,19]

Who should avoid it? Women who are pregnant or suspect pregnancy, breast cancer, unexplained abnormal uterine bleeding (AUB), and certain liver conditions.[8]

Side effects: Irregular bleeding, especially in the first few months, along with possible hormonal effects such as acne, increased hair growth, and ovarian cysts.[8,18]

Analgesics

Analgesics are medicines that help block pain signals, and may reduce how strongly cramps and pain are felt. However, they do not reduce inflammation.[9]

Examples: Paracetamol (non-opioid), tramadol (opioid)

When your doctor may recommend it: Paracetamol may be used for mild pain or when NSAIDs are not suitable.[5,9] Opioids are reserved for severe pain under medical supervision.

Who should avoid it? 

• Paracetamol: Those with liver disease or a history of allergy to paracetamol.

• Opioids: Those with a history of substance abuse, severe breathing problems, risk of suicide, mental health issues, significant liver or kidney disease. 

Side effects: 

• Paracetamol is generally well tolerated but can cause skin rashes, anemia, and kidney damage. It may also lead to liver damage if overdosed. 

• Opioids may cause drowsiness, nausea, vomiting, constipation, mood changes, itching, slow breathing, and even risk of dependence with long-term use.

Neuromodulators 

Neuromodulators work on the nervous system to change how pain signals are processed by the brain. Limited evidence suggests they help in reducing the intensity of cramps and pain in certain cases.

Examples: Gabapentin, amitriptyline

When your doctor may recommend it: For complex or chronic pelvic pain when standard treatments do not work. They are not a first-line treatment for period pain and are usually considered only in select cases.[10]

Who should avoid it? 

• Those with certain medical conditions such as kidney disease, liver disease, heart problems, psychiatric disorders. 

• Those taking certain medications such as strong opioids, NSAIDs, benzodiazepines, capsaicin, or muscle relaxants

Side effects: Drowsiness, dizziness, swelling, balance issues, dry mouth, weight gain, palpitations, feeling faint when standing up. 

Addressing Common Queries About Period Pain Relief Tablets

Many women have questions about using medicines to relieve menstrual pain, from safety concerns to common myths around addiction and fertility. Here are some of the most frequently asked questions, explained clearly.

Can painkillers delay periods?

NSAIDs do not delay periods because they do not affect the hormones that control the cycle, including estrogen and progesterone. 

Instead, they act on prostaglandins, which cause pain and inflammation. Even at high doses, NSAIDs may slightly reduce bleeding by lowering prostaglandins, but they do not change when your period starts.[1,3]

Are over-the-counter period pain medicines safe?

Certain over-the-counter (OTC) medicines, such as ibuprofen and paracetamol, are generally safe when used as directed. However, it is best to start these medicines after consulting a doctor, especially if your pain is severe or keeps coming back. 

A doctor can help rule out any underlying cause and guide you on the right timing, dose, and duration of use for your situation.[1,2]

Can you get addicted to period pain tablets?

No, standard painkillers like NSAIDs, antispasmodics, and analgesics like paracetamol do not cause dependence or cravings. The exception is opioid-based medicines. However, these are rarely used and only prescribed for severe pain under close medical supervision due to their risk of dependence.

Do period pain relief medicines cause infertility?

No, period pain relief medications do not affect fertility. In some cases, very high doses may temporarily delay ovulation, but this effect is short-term and does not last. If you have concerns, speaking with a gynaecologist can help clarify what is right for you.[1]

Is it bad to take painkillers every month for periods?

Not necessarily. It is generally safe when the pain is predictable, responds to standard doses, and medicines are used for only 1–3 days per cycle at the right time. If you need higher doses or painkillers are becoming less effective, it is worth discussing this with a doctor.[1,3]

Berry’s Insights: Can You Reduce the Need for Period Pain Medicines?

It may be possible to reduce how often you need painkillers for period pain, but this takes time. It requires getting to the root cause of the pain, not just the symptom, and using the right remedies consistently.

Most period pain is driven by high prostaglandin levels, inflammation, strong uterine contractions, and heightened pain sensitivity. Painkillers work by blocking these processes and provide relief, but only temporarily. To rely on them less, the focus needs to shift towards reducing these triggers so that each cycle begins with less intense pain.

Three evidence-informed strategies can help with this.

Targeted supplements (over 8–12 weeks)

Certain supplements are used for period pain as part of long-term management. They do not provide instant relief like painkillers, but over 2–3 cycles, many women notice less intense cramps and a reduced need for repeat dosing.

• Magnesium: Helps relax muscle contractions and may reduce cramping.[20]

• Vitamin E: May reduce prostaglandin activity and ease cramps and pain.[21,22]

• Omega-3 fatty acids: Help reduce moderate pain and inflammation.[22]

• Vitamin D (especially if deficient): Supports muscle function and prostaglandin regulation.[23,24]

More information: Learn more about supplements like Vitamin E and Vitamin D for cramps to support long-term reduction in period pain.

Heat therapy and TENS

Heat therapy and TENS are effective for abdominal cramps, lower back pain, and thigh pain.[2]

• Heat therapy for 10–30 minutes helps relax muscles and improve circulation.

• TENS for 15–20 minutes helps block pain signals and stimulates natural pain-relieving responses.[26]

These are simple remedies for period pain that can be used on their own or alongside medicines. Using these early may even reduce the need for a painkiller dose.

Lifestyle factors

Daily habits can influence how your body responds to period pain over time. Consistent changes may help improve overall comfort and reduce how intense the pain feels.

• Regular exercise: Regular movement can help lower prostaglandin levels over time and improve your body’s pain threshold.[3] Activities like walking, cycling, or light workouts for about 30 minutes, 3 times a week can be helpful. 

• Yoga: Yoga postures and breathing techniques can improve pelvic blood flow and have been shown to reduce menstrual pain scores in women with primary dysmenorrhea.[27] Simple poses such as cat–cow, child’s pose, or legs up the wall, practised for 10–15 minutes, may help. 

• Sleep and stress management: Poor sleep and ongoing stress can increase pain sensitivity, making your body more reactive to pain signals. Aim for 7–9 hours of sleep and try simple techniques like deep breathing and meditation for a few minutes daily to improve sleep quality. 

• Diet: Reducing ultra-processed foods and improving nutrient intake may help lower inflammation and support muscle function. Focus on protein-rich foods (lentils, eggs, plain yogurt, lean meats), omega-3 sources (walnuts, flaxseeds, fatty fish), and drinking 1.5–2 litres of water daily. 

Quick note: Taking action early, just before your period or at the first sign of discomfort, can reduce period pain and the need for medication. However, everyone’s bodies and symptoms vary. If you need painkillers occasionally to manage your period pain, it’s completely okay. The goal is fewer tablets, lower doses, and better control over pain, not zero medication. If pain remains severe despite these steps, consult a doctor to rule out underlying conditions.

When to See a Doctor?

Most period pain can be managed at home with prescription medications and supplements, heat therapy, TENS, and lifestyle changes. However, certain symptoms may need medical attention. It is important to speak with a doctor if you notice:

• Severe pain that prevents you from going to work, school, or doing daily activities

• Pain that is entirely unresponsive to pain relief medications, heat therapy, or TENS

• Cramps accompanied by severe nausea, vomiting, dizziness, or fever

• Pain that starts several days before your period and lasts well after it ends

• Sudden, severe pain that feels different from your usual menstrual cramps

Your doctor will ask questions to understand what may be causing the pain. Keeping a period diary for at least three cycles can help provide a clearer picture of your symptoms and whether they have changed over time.

Note: What to record in your period diary? 

A useful period diary should include:

• When the pain starts and how long it lasts

• Where you feel the pain, such as the lower abdomen, back, thighs, or legs

• The intensity of abdominal pain and whether it affects daily activities

• Other symptoms like nausea, vomiting, diarrhea, or dizziness

• Your menstrual flow, including heavy menstrual bleeding or clots

• Whether you have pelvic pain outside of your period

• Any PMS symptoms, such as mood changes, bloating, or breast tenderness

Based on this, your doctor may perform a physical or pelvic exam, and in some cases recommend tests like an ultrasound to check for causes of pain and inflammation. Once your doctor reaches a diagnosis, they will discuss treatment options with you. 

The Bottom Line

Period pain (dysmenorrhea) is common but manageable. The first step toward relief from menstrual cramps is identifying whether the pain is driven by prostaglandins or an underlying condition. 

NSAIDs are the first-line treatment for painful periods and often effective for most women. Other medicines, including hormonal contraceptives, antispasmodics, analgesics, or neuromodulators may also be used to manage period pain, depending on your symptoms and needs.

Alongside medicines, approaches such as supplements, heat therapy, TENS, and regular exercise may help reduce the severity of cramps over time. They may also lower the need for frequent pain relief medication. 

If your pain remains severe or persistent despite treatment and self-care strategies, consult a doctor for further advice. 

FAQs on period painkillers

Which tablet is best for period pain?

Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used to relieve period pain, but the right choice depends on your symptoms and overall health.

Which painkiller is best for heavy periods?

NSAIDs may help reduce pain and slightly decrease heavy bleeding during periods, but persistent symptoms should be evaluated by a doctor.

What helps period pain immediately?

Taking a painkiller at the first sign of cramps can help during your menstrual period. Applying heat or TENS to the lower abdomen and other affected areas can also provide relief.
