With your doctor's guidance, you may find a medicine that works well for you. Make sure you know how to use your medicine correctly. Take medicines only as directed. And always read warning labels. Talk to your doctor or pharmacist if you have questions.

NSAIDs (nonsteroidal anti-inflammatory drugs) relieve pain. Some can be bought over the counter. These include aspirin, ibuprofen, and naproxen. Stronger NSAIDs may be prescribed for more severe symptoms.

• Benefits. NSAIDs relieve headaches, muscle aches, and other physical symptoms. They work best when taken at the first sign of symptoms.
• Side effects. NSAIDs can cause stomach upset. Taking them with food may help.
• Other concerns. You shouldn't take more than one type of NSAID at a time. Also, NSAIDs may not be safe if you have asthma, heart disease, history of gastric ulcer, or kidney problems.

Birth control pills may be prescribed to control hormone levels.

• Benefits. Birth control pills ease a range of symptoms, including breast tenderness and appetite changes.
• Side effects. Birth control pills can cause stomach upset and headache.
• Other concerns. Rarely, birth control pills can cause blood clots. The risk is higher for cigarette smokers over age 35.

SSRIs (selective serotonin reuptake inhibitors) may be prescribed to help keep serotonin levels stable. SSRIs may be taken every day. Or they may be taken only during the 2 weeks before your period.

• Benefits. SSRIs help relieve emotional symptoms, including irritability, depression, and mood changes. They also ease physical symptoms, such as bloating, breast tenderness, and appetite changes.
• Side effects. SSRIs can cause stomach upset, sleep problems, anxiety, and headache. SSRIs may also reduce interest in sex. This is less likely when SSRIs are taken only for part of the menstrual cycle.
• Other concerns. SSRIs shouldn't be used if you take certain antidepressants.

GNRH agonists (Gonadotropin-releasing hormone) may be used in severe cases when SSRIs and birth control pills are ineffective or can't be tolerated.

• Benefits. GNRH agonists stop the normal hormonal cycle, effectively causing a temporary menopause, so the cyclic changes are no longer present.
• Side effects. GNRH agonists stop your period and cause hot flashes and bone loss unless given with add-back treatment, which consists of continuous doses of estrogen and progestin.

Surgery to remove your ovaries should be reserved for very severe cases that don't respond to medical treatment. This should be considered only after very careful consideration of the long-term effects and only after childbearing is complete.
