Have you discussed your alleged negative side effects with your primary care physician?
Before you consider a lawsuit, I suggest you initiate a conversation and thorough medical examination with the physician who prescribed the medication.
In addition to being an attorney, I'm also a licensed osteopathic physician.

Montelukast (Singulair): Uses, Side Effects, Dosage & Reviews
Tips
May be taken with or without food. Available as tablets, chewable tablets, and oral granules. The granules can be administered directly into the mouth or dissolved in a teaspoonful of breast milk or formula, or soft food such as applesauce, carrots, rice, or ice cream. Once the packet is opened, the contents should be taken within 15 minutes. Discard any unused portion.
Take once daily in the evening when used as a preventative treatment for asthma.
Take montelukast daily as prescribed, even if you have no symptoms of asthma. Do not take another dose of montelukast within 24 hours of a previous dose. Do not increase or decrease the dose of montelukast without your doctor's permission and continue to take all other asthma medications as prescribed.
Take montelukast two hours before exercise when using to prevent exercise-induced bronchospasm (EIB). If you are already taking montelukast on a daily basis, you do not need to take an additional dose to prevent EIB.
Take exactly as prescribed when given for asthma, even if you are asymptomatic. Continue taking as prescribed even during an acute asthma attack.
If you miss a dose, take it as soon as possible. But if it is almost time for your next dose, just skip that dose. Do not double up on doses.
Chewable tablets are typically taken once daily in the evening (although studies have not been conducted to evaluate if there is any difference in effectiveness with morning dosing). Chew the tablets thoroughly before swallowing.
If you are having an acute asthma attack, take your short-acting bronchodilator medicine (for example, albuterol) as prescribed. Talk to your doctor if you regularly need to take more of your acute asthma treatment.
Notify your doctor if you experience any neuropsychiatric effects (such as aggression, anxiety, depression, or hallucinations) while taking montelukast.
Also, tell your doctor if you develop any symptoms of an allergic reaction including a rash or breathing problems; or side effects such as an abnormal heartbeat, unusual bruising, yellowing of the skin or eye, trouble sleeping, or a tingling or twitching in your fingers and toes.
Avoid driving or operating machinery if montelukast makes you drowsy or dizzy.
If you know you are sensitive to aspirin or other NSAIDs, continue to avoid these while taking montelukast.
If you have phenylketonuria, be aware that the 4 and 5mg chewable tablets contain phenylalanine.
Tell your doctor if you are breastfeeding, pregnant, or intending to become pregnant because they will need to discuss the risks versus benefits of using montelukast while pregnant or breastfeeding.
Medicines that interact with montelukast may either decrease its effect, affect how long it works for, increase side effects, or have less of an effect when taken with montelukast. An interaction between two medications does not always mean that you must stop taking one of the medications; however, sometimes it does. Speak to your doctor about how drug interactions should be managed.
Common medications that may interact with montelukast include:
anticonvulsants, such as carbamazepine, divalproex, fosphenytoin, or phenytoin
antifungals, such as fluconazole, miconazole, or voriconazole
echinacea
fibrates, such as gemfibrozil
fluvoxamine
heart medications, such as amiodarone
HIV medications, such as efavirenz
isoniazid
metronidazole
nafcillin
phenobarbital
rifampin
St. John's wort
sulfamethoxazole
tamoxifen
trimethoprim
zafirlukast.
Note that this list is not all-inclusive and includes only common medications that may interact with montelukast. You should refer to the prescribing information for montelukast for a complete list of interactions.

Were you or a loved one diagnosed with a mental health disorder after taking Singulair?
Case Review
Do I Qualify for a Singulair Lawsuit?
If you or a loved one took brand name Singulair and received a diagnosis of a mental health disorder, such as those listed on the Singulair black box warning, you may qualify to file a Singulair lawsuit for compensation.
Neuropsychiatric disorders linked to Singulair include:
Major depressive disorder
Suicide
Institutionalization for psychiatric disorders
Obsessive-compulsive disorder
Homicidal thoughts
Suicidal thoughts
Non-psychiatric injury
Anxiety disorder
Other psychiatric disorders
In general, the time limit to file a claim for injuries caused by a drug is about three years, but this varies by state and may be less.
This can change depending on when you took the drug or when you discovered the drug's side effects. Make sure you contact an attorney right away if you believe you qualify to file a claim.
Filing on Behalf of a Family Member
Parents or caregivers can file on behalf of their children, and family members can file a suit for loved ones who died as a result of Singulair side effects.
When parents file on behalf of their child, they claim damages they incurred as guardians of the child, such as paying for medical bills. They also file for injuries their child suffered. Wrongful death claims are filed on behalf of deceased family members.
Experienced law firms can walk parents and family members through the process of starting a claim.
Preparing to File a Lawsuit
Once you've confirmed you took brand name Singulair and have received a diagnosis, it's time to start the lawsuit process.
Step 1: Finding an Experienced Law Firm
The first thing you need to do is find a law firm that has experience handling complex pharmaceutical litigation claims.
It's an important decision, so make sure you ask about the firm's track record and experience. Remember, you can interview more than one firm.
Step 2: Preparing Necessary Documentation
Once you've decided on the law firm you want to hire, sign up for a free consultation.
Before you talk to your attorney, make sure you have proof you took brand name Singulair, such as a receipt. Also gather medical records showing your diagnosis.
If you have difficulty getting these records, your attorney may be able to help.
Step 3: File the Claim
Once your attorney has determined you qualify to file a claim, he or she will start the process by writing up the complaint and filing the claim in the appropriate court.
Is There a Singulair Class-Action Lawsuit?
So far, there are no class action lawsuits for Singulair's mental health side effects. The lawsuits currently being filed are individual lawsuits.
Members of class actions don't get to choose their attorneys, and all the members of the class are awarded the same amount of money regardless of the severity of their injuries. For this reason, most drug lawsuits similar to Singulair lawsuits are individual claims.
When hundreds or thousands of plaintiffs sue the same defendants for similar injuries, a judge may decide to consolidate the cases into multidistrict litigation (MDL).
Cases in an MDL may share some resources such as discovery and experts, but each individual chooses their own lawyer and any settlement or jury verdict amount is based on the individual merits of their case.
