Other precautions
Discuss your medical history with your doctor before taking Prozac. Prozac may not be suitable for you if you have certain medical conditions or other factors impacting your health. These are drug-condition or drug-factor interactions. The conditions and factors to consider include:
Mental Health Issues. If you're dealing with any mental health disorders like bipolar disorder, it's crucial to inform your doctor before starting Prozac. This medication might enhance the probability of manic episodes in some individuals with specific mental health issues. Your doctor can evaluate if Prozac is a suitable choice for you given your condition.

If you already have a seizure disorder, Prozac might further aggravate your chances of having a seizure. Consult your doctor to understand if Prozac is safe for you.
Eye Problems. Prozac might elevate eye pressure, which could worsen glaucoma. If you have glaucoma, discuss this with your doctor to learn if Prozac is appropriate for you.
Heart Problems. If you have heart concerns, such as arrhythmia, inform your doctor before taking Prozac. This medication may enhance your risk of heart rhythm issues. If you already have a heart condition, Prozac might exacerbate your condition. Your doctor can help determine if Prozac is safe for you.
Bleeding Issues. Prozac might increase your risk of bleeding. If you have a bleeding disorder, Prozac might exacerbate these symptoms. Disclose any bleeding disorders you may have to your doctor before taking Prozac.
Allergic Reactions. If you've experienced an allergic reaction to Prozac or its components, your doctor may be less likely to prescribe Prozac for you. Consult your doctor about alternative medications.
Liver Issues. Prozac is eliminated from your system through your liver. If your liver isn't functioning properly, Prozac may build up in your body. This could increase the risk of side effects from the drug. Discuss any liver problems with your doctor before starting treatment.
Electrolyte Levels. Prozac might decrease sodium (salt) levels in your blood. If you have an electrolyte condition such as low blood sodium levels, taking Prozac might increase your risk of side effects. Moreover, Prozac might boost your risk of heart issues, such as an increased heart rate, if you have an electrolyte issue.
If you have low electrolyte levels, consult your doctor before starting Prozac treatment. They may suggest managing your electrolyte levels prior to administering Prozac.
Age. Older adults (65 years or older) may be at a higher risk of side effects while using Prozac. If you're an older adult, your doctor may monitor you more closely for side effects.
Electroconvulsive Therapy. If you receive electroconvulsive therapy (ECT) for treatment-resistant depression, you might be at a higher risk of seizures when taking Prozac. Consult your doctor to ascertain if Prozac is safe for you in this situation.
Diabetes. Prozac might affect your blood sugar, potentially worsening your diabetes and increasing your risk of low blood sugar. If you have diabetes, your doctor may recommend more frequent blood sugar monitoring while using Prozac.
Alcohol and Prozac
There aren't any known interactions between Prozac and alcohol.
However, combining alcohol and Prozac might increase your risk of side effects from the drug. Both Prozac and alcohol may cause symptoms like:
- nausea

Discuss this with your doctor to determine if it's safe for you to drink alcohol while using Prozac.
Pregnancy and Breastfeeding while using Prozac
It may not be safe to use Prozac during pregnancy or while breastfeeding.
Selective serotonin reuptake inhibitors (SSRIs), including Prozac, might increase the risk of certain developmental problems, such as difficulty breathing, trouble feeding, and irritability. Additionally, Prozac might enhance the risk of pulmonary hypertension (high pressure in the lungs) in a newborn.
