Zomig (zolmitriptan) Nasal Spray is a headache medicine that narrows blood vessels around the brain used to treat migraine headaches. Zomig Nasal Spray will only treat a headache that has already begun. Zomig Nasal Spray will not prevent headaches or reduce the number of attacks. Common side effects of Zomig Nasal Spray include unusual or unpleasant taste in your mouth, discomfort in the nose or throat after using the nasal spray, warmth/redness/tingling/numbness under the skin, nausea, dry mouth, weakness, drowsiness, dizziness, or pressure or heavy feeling in any part of your body.
The initial dose of Zomig is 2.5 mg or less. The dose can be repeated after 2 hours if symptoms persist. The maximum dose is 10 mg per day. Zomig may interact with other migraine headache medicines, cimetidine, or antidepressants. Tell your doctor all medications you are taking. During pregnancy, Zomig should be used only when prescribed. It is unknown if this drug passes into breast milk. Consult your doctor before breast-feeding.

Zomig Overview - Patient Information: Side Effects
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
This medication may raise your blood pressure. Check your blood pressure regularly and tell your doctor if the results are high.
Tell your doctor right away if you have any serious side effects, including: blue fingers/toes/nails, cold hands/feet.
Chest/jaw/neck tightness can commonly occur soon after using zolmitriptan. Only rarely are these signs of a serious condition. However, you may not be able to tell it apart from a serious reaction due to a lack of blood flow to the heart, brain, or other parts of the body. Get medical help right away if you have any very serious side effects, including: chest pain, jaw/left arm pain, fainting, fast/irregular/pounding heartbeat, vision changes, weakness on one side of the body, confusion, slurred speech, sudden or severe stomach/abdominal pain, bloody diarrhea, change in the amount of urine.
This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take (see Drug Interactions section). Get medical help right away if you develop some of the following symptoms: fast heartbeat, hallucinations, loss of coordination, severe dizziness, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever, unusual agitation/restlessness.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Clinical Trials Experience
Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice.
In a long-term, open-label study where patients were allowed to treat multiple migraine attacks for up to 1 year, 8% (167 out of 2,058) withdrew from the trial because of adverse reaction.
The most common adverse reactions (≥ 5% and > placebo) in these trials were neck/throat/jaw pain, dizziness, paresthesia, asthenia, somnolence, warm/cold sensation, nausea, heaviness sensation, and dry mouth.
Table 1 lists the adverse reactions that occurred in ≥ 2% of the 2,074 patients in any one of the ZOMIG 1 mg, 2.5 mg, or 5 mg dose groups in the controlled clinical trials of ZOMIG in patients with migraines (Studies 1, 2, 3, 4, and 5) [see Clinical Studies]. Only adverse reactions that were at least 2% more frequent in a ZOMIG group compared to the placebo group are included.
Several of the adverse reactions appear dose related, notably paresthesia, sensation of heaviness or tightness in chest, neck, jaw, and throat, dizziness, somnolence and possibly asthenia and nausea.
Table 1: Adverse Reaction Incidence in Five Pooled Placebo-Controlled
Migraine Clinical Trials1
|ZOMIG 1 mg
|ZOMIG 2.5 mg
|ZOMIG 5 mg
|Paresthesia (all types)||2%||5%||7%||9%|
|PAIN AND PRESSURE SENSATIONS||7%||13%||14%||22%|
|Chest - pain/tightness/pressure and/or heaviness||1%||2%||3%||4%|
|Heaviness other than chest or neck||1%||1%||2%||5%|
|1 Only adverse reactions that were at least 2% more frequent in a ZOMIG group compared to the placebo group are included.|
There were no differences in the incidence of adverse reactions in controlled clinical trials in the following subgroups: gender, weight, age, use of prophylactic medications, or presence of aura. There were insufficient data to assess the impact of race on the incidence of adverse reactions.
Less Common Adverse Reactions with ZOMIG Tablets
In the paragraphs that follow, the frequencies of less commonly reported adverse clinical reactions are presented. Because the reports include reactions observed in open and uncontrolled studies, the role of ZOMIG in their causation cannot be reliably determined. Furthermore, variability associated with adverse reaction reporting, the terminology used to describe adverse reactions, etc., limit the value of the quantitative frequency estimates provided. Adverse reaction frequencies were calculated as the number of patients who used ZOMIG tablets and reported a reaction divided by the total number of patients exposed to ZOMIG tablets (n=4,027). Reactions were further classified within body system categories and enumerated in order of decreasing frequency using the following definitions: infrequent adverse reactions (those occurring in 1/100 to 1/1,000 patients) and rare adverse reactions (those occurring in less than 1/1,000 patients).
General: Infrequent were allergic reactions.
Adverse Reactions with ZOMIG-ZMT Oral Disintegrating Tablets
The adverse reaction profile seen with ZOMIG-ZMT oral disintegrating tablets was similar to that seen with ZOMIG tablets.
The following adverse reactions were identified during post approval use of ZOMIG. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
The reactions enumerated include all except those already listed in the Clinical Trials Experience section above or the Warnings and Precautions section.
As with other 5-HT1B/1D agonists, there have been reports of anaphylaxis, anaphylactoid, and hypersensitivity reactions including angioedema in patients receiving ZOMIG. ZOMIG is contraindicated in patients with a history of hypersensitivity reaction to ZOMIG.
